EXTERIOR DESIGN
The fourth generation GS features an all-new exterior reflecting a further
development of Lexus’ unique, L-finesse design philosophy, making the
car look bolder and more dynamic.
Though remaining the same length, the new GS has a 10mm shorter
front overhang, a 10mm longer rear overhang and is 30mm higher than
its predecessor. Improving high speed stability, the front track has been
increased by 40mm and the rear track by 50mm. Overall vehicle width
has increased by 20mm.
Key to the new design is a more aggressive frontal treatment which gives
the new GS the powerful, commanding road presence appropriate to a
Lexus sports sedan.
In a further evolution of a styling cue first developed on the CT 200h,
the inverted trapezoid upper grille and slanted lower grille have been
combined and integrated into a single element, bridging the bumper midsection to create a prominent ‘spindle’ shape. The brake cooling ducts at
either side of the spindle grille combine a distinctive style with engineering
functionality.
This bold, elegant and highly individual grille treatment makes the GS
instantly recognisable as a Lexus at first glance, and will be adopted
throughout the brand to strengthen the Lexus family identity between
model ranges.
The grille is flanked by headlamp clusters clearly positioned on a higher
plane than the grille itself. This is a unique characteristic of Lexus models,
focusing the eye at the very apex of the vehicle to give the design a resolute
look and strengthen the impression of speed and agility.
7
The headlamps themselves are underscored by newly developed, integral
LED Daytime Running Lights (DRL) which form the L-finesse arrowhead
motif, further reinforcing the unique visual signature of the new GS.
Exclusive to the hybrid GS 450h, a unique three-lamp design aligns
the turn signal and Lexus-first high and low beam LED lamps in a single
horizontal row. The improved illumination and beam range provided by
LED lamps offers significantly superior visibility even under low beam
driving conditions.
Integrating sharply sculpted front foglamp housings, the deep front
bumper forms a wide, trapezoid shape which anchors muscular front
wings and flared wheel arches, reinforcing the new GS’s wider front track,
broad stance and powerful road presence.
In profile, the new GS shares its predecessor’s long, elegant cabin
proportions and slingshot window design highlighted by a stainless steel
door frame moulding. But a new, 15mm higher roofline reflects the increase
in rear passenger accommodation and boot space whilst providing
optimum aerodynamic performance for a drag coefficient of Cd 0.26.
The door handle design has been changed, making it easier to grip, and
the smart entry lock mechanism has been changed from a push switch
to a touch sensor, improving both appearance and operability. The door
8
mirror now incorporates both an LED side turn signal lamp and a puddle
lamp. Both the door panel gaps and the gap between wheel arches and
tyres have been reduced, further enhancing the appearance of the new
GS model range.
To the rear, the new design narrows behind the flared wheel arches,
exposing the lower portion of the rear tyre to emphasise the vehicle’s wide
rear track. LED lamp clusters feature aero-stabilising fins to enhance the
aerodynamic efficiency and driving stability of the car. Uniquely, the rear
bumper of the GS 450h covers the exhaust pipe apertures.
In addition to its new headlamp design, the new GS 450h may be further
identified by hybrid-specific, front, rear and side blue badging.
F SPORT Exclusive Features
The F SPORT package is available across the entire GS model range.
F SPORT exterior design features include exclusive front grille and
bumper, rear bumper and lip spoiler treatment, 19” alloys and gradespecific badging.
The F SPORT front bumper design features a more three-dimensional
form at the sides, incorporating enlarged side grilles. Combined with an
exclusive, upper and lower grille mesh design, this reinforces the new GS’s
more aggressive appearance, wider track and sporting stance.
9
To the rear, F SPORT petrol engine models feature a grey metallic paint
finish to the bumper diffuser. The GS 450h F SPORT diffuser combines
grey metallic paint with a chrome plated moulding to the lower section of
the bumper to further enhance the vehicle’s road presence.
INTERIOR DESIGN
All F SPORT models further benefit from a grade-specific rear spoiler and
exclusive, dark premium metallic 19” alloy wheels.
The new GS interior represents a continuation of the next generation
Lexus interior design theme first seen in the CT 200h. With all functional
driving components consolidated in the driver’s seat surroundings, it
combines outstanding ergonomics with advanced Human Machine
Interface technologies.
Exterior Colours
The new GS is available in a choice of 11 colours, including three that are
new to the Lexus colour palette: Crimson Red, Meteor Blue and Sonic
Silver. Vehicles in Crimson Red benefit from glass flakes incorporated into
the coating, adding a high level of brilliance to the paint.
Lexus engineers developed a new advanced coating process for the
Sonic Silver finish. The new GS is the first Lexus to adopt this new coating
technology. Vehicles with the Sonic Silver exterior appear more radiant as
an additional metallic texture gives both strong shading and defined, sharp
highlights. This metallic effect makes subtle and defined bodylines more
noticeable and the surface appear finely polished.
10
An ergonomically designed, driver-focused cockpit enabling customers
to remain alert and comfortable over long periods of time is an essential
requirement of a sports sedan.
Driver Focused Cockpit
A clean, elegant dashboard design forms a wide horizontal plane,
emphasising the overall roominess of the interior, whilst the door and
centre console trim support the driver and front passenger in a secure,
cocooned environment.
The dashboard is divided into two distinct zones: an upper Display Zone,
with the largest, ultra-wide, 12.3 inch, LCD multi-display screen yet installed
in a production car, located at an ideal distance for at-a-glance viewing,
and a lower Operation Zone, which allows access to system controls such
as the second generation of Lexus’ award winning, computer mouse-style
Remote Touch Interface (RTI).
11
Every aspect of the driving position has been carefully considered to
create the ideal placement of controls, maximise comfort and minimise
driver distraction and fatigue
Brake pedal operability has been optimised with a new pedal shape and
surface angle, and the footrest size increased to 300mm for a better fit
and greater comfort.
A new front seat features a lower hip point, placing the driver closer to
the GS’s centre of gravity, and combines optimum holding ability with
superlative comfort. An extended seat sliding range caters for the widest
possible cross-section of occupants. As well as a new mid seat back
folding adjustment, multiple adjustment mechanisms include a butterfly
headrest, shoulder support, side support, 4-way lumbar support, and a
cushion length adjustable by 76mm .
The driver’s instrument binnacle incorporates large diameter Optitron
dials. Minimising the driver’s eye movement from the road ahead, a new
Head-Up Display (HUD) relays essential driving information. Its visibility
has now been significantly improved. By implementing a wedge-shaped
glass for the windshield and the PVC film for displaying information, the
clarity of projection has been increased as well as double image projection
avoided. The HUD now displays a wider range of information including
SPORT mode (tachometer) display and ECO bar display in addition to
the speed and audio displays already implemented.
The airflow volume of the seat ventilation system has been increased to
almost twice that of the current model. And soft padded, tactile finishes to
the centre console arm rest, knee pads and door arm rests further enhance
the long-distance comfort of the driving position.
The steering wheel features an enlarged, 50mm telescopic reach to
bring it closer to the driver, and has been set at a low angle to facilitate
large steering inputs without the need for the driver to move their body
unnecessarily through over-reaching. Even the cross-section has
been painstakingly analysed; no longer uniform throughout the entire
circumference of the wheel, its varying profile allows for a relaxing grip
and smooth steering inputs.
12
The driver’s forward visibility has also been maximised – slim A pillars and
a taller windscreen creating a wider field of view. And even the bonnet
visibility range has been tailored to allow the driver to readily establish
the vehicle extremities, making it easier to place when manoeuvring in
confined spaces.
Comfort, Convenience and Contemporary Craftsmanship
Despite having an identical wheelbase length to that of its predecessor,
the new GS offers increased space and comfort to all vehicle occupants.
Both front and rear door openings have been designed for maximum ease
of ingress and egress, with a particular focus on head clearance.
Front cabin occupants benefit from a new seat back design which is more
comfortable for taller passengers. A greater seat sliding range and seat
height adjustment give an increase in legroom and up to 30mm of extra
headroom.
Rear seat passengers benefit from new seats with a revised seat back angle
and redesigned cushion shape for greater comfort. A thin front seat design
improves knee room by 20mm, and headroom has been increased by
25mm.
Allied to a new, more compact rear suspension layout, a wider opening,
increased deck length and reduced deck height combine to make the new
GS’s luggage space more practical, and significantly increase its volume
to up to 566 litres2 (a 31% increase over the current GS 350). The smartpackaging of the hybrid battery into a stacked format also increased the
GS 450h’s luggage capacity to up to 482 litres2 (a 61% increase over the
current GS 450h).
Throughout the interior, high-quality materials and finishes convey a
contemporary, premium look and feel, with a level of craftsmanship and
attention to detail for which Lexus is globally renowned.

A new interior colour scheme replaces the traditional two-tone design
with a more versatile palette. The dashboard, floor and steering wheel
are uniformly black to create a sporting, luxurious feel. And the leather
instrument panel features coloured stitching - available in grey and ivory
depending on the interior tone- to enhance the premium quality of the
cabin environment.
This beautifully crafted interior is complimented by an all-white LED
interior lighting system which creates an atmosphere appropriate to a
premium performance sedan. Reinforcing the GS’s highly refined onboard ambience, elements of the LED lighting illuminate to greet the
occupants as they approach the car, even before it is unlocked, activating
and fading thereafter in sequence with the vehicle starting procedure.
Matching seat and door upholstery will be available in a choice of six
colours - Black, Ivory, Grey, Saddle Tan, Topaz Brown and Garnet. In
addition to Ebony, Walnut and Bamboo wood finishes, newly developed
Black Gloss and Aluminium bring a contemporary, artistic look and feel to
the interior ornamentation.
F SPORT Exclusive Features
F SPORT model interior design features include matching door and seat
upholstery also available in Garnet -a grade-exclusive colour, combined
with newly developed Aluminium ornamentation, 16-way electrically
adjustable F SPORT front seats, a black headliner and pillar finish, a dimple
perforated leather steering wheel and gear knob, Aluminium pedals and
dashboard trim, exclusive black logo scuff plates and F SPORT badging
to the steering wheel.
A world first, the steering wheel of the GS 450h will be available in a
real bamboo finish, symbolising the innovative spirit and environmental
credentials of the vehicle’s Lexus Hybrid Drive system.
INNOVATIVE ON-BOARD TECHNOLOGIES
The GS interior’s air of sophistication and luxury is reinforced through
Lexus’ painstaking attention to detail throughout. It incorporates exquisitely
crafted details such as satin metal trim, high quality stitching and the
brushed aluminium knobs of the audio system. A new analogue clock with
LED indicators, carved from an ingot, adds a unique touch.
14
Several highly innovative technologies make a first appearance in the new
GS model range, including a new, energy saving air-conditioning system
with S-Flow and ‘nanoe’ technologies, a second generation Remote Touch
Interface (RTI) linked to the world’s largest on-board multi-information
display screen, and a choice of audio systems offering unparalleled power
and clarity.
Second Generation RTI with 12.3” Multimedia Display
The second generation Lexus Remote Touch Interface (RTI) multi-function
control device has been enhanced for increased user-friendliness and
ease of operation.
It now features the world’s first slide haptic joystick mechanism -a planar
slide-type controller that is much like a computer mouse, and the ENTER
command is now accomplished by simply pushing the controller. Usability
has also been improved through the addition of ambient lighting, and by
minimising the difference in height between the RTI controller and the
armrest.
RTI allows users to manipulate the cursor quickly and easily across the
world’s largest on-board multimedia display; a 12.3 inch, full colour, LED
screen with an ultra-wide, 24:9 format. The screen’s size allows for the
permanent display of two types of information simultaneously, such as
map/audio, night view/map and navigation input/incoming call.
Improved Navigation System
The new GS’ navigation system has been enhanced by using also TPEG
(Transport Protocol Expert Group) data including TFP (Traffic Flow and
Protection) information, parking lot availability and fees which additionally
allows to set a certain parking slot as destination.
S-Flow Air Conditioning with Nanoe Technology
Considerably more powerful than the previous system, the new airconditioning features S-Flow technology to maintain optimum occupant
comfort whilst significantly reducing power consumption. Using sensors
it determines if the front passenger seat is occupied. If not, the system
automatically closes all vents serving this seat. The same happens to the
rear seats when the S-Flow button is switched on. This maximises system
efficiency.
In addition the system measures the ambient air temperature, interior air
temperature and insolation to determine the optimal level of air conditioning.
The target airflow volume is customised for each seat through Temperature
Airflow Output (TAO) control. When the thermal load is large (cooldown
in summertime, warm-up in winter) air conditioning is implemented in the
entire car to quickly obtain a comfortable interior temperature. Once the
overall interior temperature is stabilized, the system concentrates only on
occupied seats.
During the development of the centralised occupant sensing control
system, intensive vehicle tests in wind tunnel facilities were performed. The
system was also repeatedly tested on both test courses and actual roads to
ensure it maintains comfortable driving in a range of environments.
15
In addition to the TAO control, upper and lower independent, multilayer air
mix technology has been adopted to achieve an environment tailored for
both driver, front and rear passengers. This allows for example to set the
upper air mix for coolness to deal with effects of solar insolation, and at the
same time the lower air mix for warmth.
The new system also introduces a 2-tier Interior / Exterior Air Control
which prevents window fogging by inducing low humidity exterior air to the
upper half of the cabin while maintaining excellent heating performance in
the foot area by circulating interior air. This avoids ventilation losses which
are characteristic to conventional control system where cold exterior air is
induced into heated interior air.
The new GS is also equipped with a new deodorizing filter, which, in
addition to the removal of pollen and dust, etc., also removes exhaust gas
from the ambient air.
In addition, the air conditioning system incorporates a new ‘nanoe’
technology system. This air cleaning technology operates automatically
when the air conditioning is turned on. It releases 20 to 50Nm diameter
nanoe particles -negatively charged ions wrapped in water moleculesinto the cabin via the driver’s side dashboard air vent.
16
By attaching themselves to airborne particles and molecules, the nanoe
ions have been said to have both an air purifying and odour eliminating
effect. They also deodorise vehicle seats and ceiling to create a cleaner
cabin environment.
In addition, because nanoe moisture content is approximately 1,000 times
that of conventional ions, the emission of ions bonded to water molecules
is said to have a moisturising effect on skin and hair, acting to enhance
occupant well-being.
Audio Systems
The new GS range may be equipped with a choice of two audio systems.
The standard system represents the next generation of realism and clarity in
Lexus sound. It features a fully digital Class-D amplifier capable of creating
virtually distortion-free sound with minimal voltage losses. The natural
sound dynamics and rich harmonies generated by the high definition
amplification are faithfully reproduced by an enhanced, 12-speaker layout
which features a new, front three-way system.
The new top of the range 17-speaker Mark Levinson® Premium Audio
system creates sound based on the concepts of Effortless Dynamics and
Effortless Transient Response, which combine natural dynamics with high
response and tracking performance to offer sound quality equivalent to
that of a live, concert hall performance.
Using the same technologies as those found in top-end home audio
systems, it features a newly developed, Generation III ML5 amplifier. Far
outstripping the performance of the current GS sound system, the new
amplifier generates 125 Watts per channel and a total of 835 Watts (75W
and 505W more power respectively than the current system), whilst
consuming just 6.5 Amps –less than a quarter of the power consumed by
the current generation system.
Developing twice the volume for the same power consumption,
GreenEdgeTM power-saving technology has been incorporated into each
of the 17 speakers. GreenEdgeTM technology covers a wider frequency
band than conventional systems, giving an enhanced dynamic range.
The new Mark Levinson® system features five, newly-developed, 90mm
GreenEdgeTM Unity speakers with a coaxial structure which integrates
mid- and high-range units within the same structure. The all-round cabin
positioning of the five Unity speakers gives consistent timbre for both front
and rear seat occupants, resulting in a whole new level of surround sound,
definition, atmosphere and quality.

DRIVING DYNAMICS
• Rigid bodyshell and new suspension for optimum agility and stability
with superb ride comfort
• Adaptive Variable Suspension (AVS) to further enhance ride quality,
stability, body control and steering response
• Powerful brakes for enhanced stopping power and control
• Drive Mode Select function for a choice of ECO, NORMAL,
SPORT S and SPORT S+ driving modes, and manual paddle shift
override
• GS 450h F SPORT also available with the Lexus Dynamic Handling
system - an integrated four-wheel steering system for sharper
response and greater agility
• Lexus Dynamic Handling system - the world’s first hybrid vehicle
integration of Dynamic Rear Steering (DRS), Variable Gear Ratio
Steering (VGRS) and Electric Power Steering (EPS)
The new GS has been designed to offer customers a much more engaging
and pleasurable driving experience. It combines sharp, responsive steering
and excellent body control with outstanding high speed stability and all the
ride comfort expected from a Lexus performance sedan.
The significant improvements to the next generation GS’s driving dynamics
have been achieved on three levels:
1. A re-engineered bodyshell with a 14% increase in rigidity, new suspension
to promote optimum agility and stability whilst maintaining ride comfort,
and more powerful brakes for enhanced stopping power and control.
2. Adaptive Variable Suspension (AVS) to further enhance ride quality,
stability, body control and steering response.
3. The Lexus Dynamic Handling system; leading edge platform technology
which offers the world’s first integration of Dynamic Rear Steering (DRS),
Variable Gear Ratio Steering (VGRS) and Electric Power Steering
(EPS), to coordinate every aspect of front and rear wheel control and
provide agile, sharp and confident driving behaviour with a more direct
response to the driver’s actions.
Body Rigidity
Extensive computer aided design has been used to optimise body rigidity,
ensuring precise vehicle movement in response to steering input.
The next generation GS features new underbody, rear suspension member
and front end module components. Increased spot or laser welding has
improved rigidity to the door openings, rear under body and rear partition.
Additional reinforcement or thicker gauge sheet metal has been employed
in the cowl panel, front and rear underbody and rear partition. And the
design of the front suspension member, rocker inner and dash panel has
been made stronger.
19
In combination, these enhancements have increased bodyshell torsional
rigidity by 14%, allowing the new GS to respond with much greater accuracy
to the driver’s commands.
Aerodynamics
The new GS marks the introduction of a completely new approach to the
management of airflow over the vehicle body – aerodynamic damping. The
basic concept involves bringing the flow of air closer to the vehicle body,
using it to help control the vehicle’s movement to enhance handling stability.
Allied to smooth, flowing bodywork boasting exceptionally narrow panel
gaps and minimal protrusions, the addition of numerous aerodynamic
under-body elements and aero-stabilising fins further promotes vehicle
stability and helps reduce wind noise to a minimum.
Particular attention has been paid to rectification of the airflow along the
vehicle sides to provide body movement damping. The smoothing of
airflow in and around the front and rear wheel arches, and the reduction
of air pressure within the wheel arch itself contribute to improved steering
response, a flat ride and enhanced road holding. In addition, the rear lamp
clusters feature aero-stabilising fins which generate a vortex to the rear of
the vehicle, helping to improve handling stability.
20
Acting in combination, these elements give the new GS optimum
aerodynamic performance, and a drag coefficient of only Cd 0.26.
Suspension
The new GS features a double wishbone front and multilink rear suspension
system which combines legendary Lexus ride comfort with excellent agility,
optimum steering feel and a particular focus on rear stability.
The front, high-mount, double wishbone suspension set-up incorporates
newly designed, unequal length upper and lower control arms in forged
aluminium, to both reduce system weight and improve ride comfort. The
Front double wishbone
suspension
rigidity of upper and lower arms, the hub bearing unit and the steering knuckle
has been increased to enhance steering responsiveness. Caster trail has been
increased to enhance straight line stability and steering feel.
Optimising roll attitude, the stabiliser arm ratio has been improved, the
stabiliser system spring rate increased, and the shock absorber rebound
spring rate substantially increased. In addition, lower bushing has been
enlarged to minimise the transmission of vibrations.
To the rear, an advanced multilink set-up with toe control bars and an
aluminium rear axle carrier has been completely redesigned. The spring and
shock absorber have been separated to increase their efficiency and create a
more compact design which improves the vehicle’s luggage capacity.
Rear stability has been significantly improved through the addition of
a rebound spring; increased stabiliser shock absorber arm ratios; the
replacement of suspension ball joints with bush joints; the positioning of the
toe control arm at the rear and the minimisation of toe change during the
suspension stroke.
In addition to greatly increasing rear stability, these components also
combine to improve the new GS’s roll posture, ride comfort and straight line
stability, whilst reducing harshness. Ride comfort has been further improved
by the adoption of low-friction oil in both front and rear shock absorbers.
Rear multilink suspension
F SPORT Suspension
F SPORT models feature retuned front and rear suspension to further
enhance the efficiency of the Adaptive Variable Suspension (AVS) system,
maximising body control and steering response for improved vehicle agility.
Both front and rear shock absorber characteristics have been modified
to optimise AVS damping control, and the adoption of low-viscosity oil
reduces friction for improved shock absorber efficiency. In addition, the rear
suspension shock absorber has been inclined further to the rear, and the
lower bushing enlarged and stiffened.
21
In combination, these modifications maximise the AVS system’s control of
body roll and, hence, improve the vehicle’s response to steering inputs for
increased agility and a more engaging driving experience.
Brakes
Featuring 334 x 30mm ventilated discs to the front and 310 x 18mm solid
discs to the rear, the GS’s braking system has been designed to offer drivers
enhanced power and control, with improved pedal feel and a consistently
fade-free performance. Simultaneously, tyre friction characteristics and ABS
control have also been enhanced to minimise stopping distances.
Brake booster power has been increased, and the pedal shape, angle and
ratio changed to provide instant response to changes in applied pedal
force and greater controllability. Brake cooling performance has also been
improved through an increase in ducted cooling airflow volume, minimising
brake fade even under protracted use.
The GS 450h’s Electronically Controlled Braking (ECB) system
characteristics have also been modified to provide greater responsiveness
from the first touch of the pedal.
All GS models fitted with the F SPORT package are equipped with larger,
356 x 30mm ventilated front discs. A world-first, the hat section of the two
22
piece rotor has been fabricated in aluminium to both reduce weight and
suppress heat deformation.
Adaptive Variable Suspension (AVS) system
The Adaptive Variable Suspension (AVS) system allows the driver to fine tune
the GS’s ride characteristics with a choice of two damper settings; ‘Normal’
mode, for everyday driving comfort, and ‘Sport S+’ mode, for improved body
control and precise responses to steering input whilst cornering.
In response to driving operation, vehicle body motion and road surface
conditions, AVS automatically adjusts the performance of the suspension at
Adaptive Variable Suspension
all four wheels independently activates the adjustable damping force shock
absorbers to fulfil a wide range of specific control functions.
the airflow volume is lowered when in ‘high’. Additionally, the air-conditioning
stays switched off until engine cooler water reaches 30.5°C.
Selecting the AVS system’s ‘Sport S+’ mode automatically increases the
difference between inner and outer shock absorber damping through corners
to further reduce vehicle roll. Simultaneously, VGRS automatically reduces the
steering gear ratio by approximately 10% whilst the Electric Power Steering
(EPS) increases steering assist torque by some 4%. These measures combine
to minimise body roll, sharpen vehicle handling and optimise steering feel for
the ultimate in sports sedan driving.
The ECO mode can be selected by turning the dial anti-clockwise. Once
selected, the meters and the ‘ECO mode’ indicator are illuminated blue.
In SPORT S mode the powertrain is adapted to increase acceleration response.
In the petrol version this results from a shift timing change; in the hybrid version
it is achieved through drive force and engine responsiveness enhancements in
the partial and full throttle range respectively. SPORT S mode can be selected
Drive Mode Select System
The next generation GS features a Drive Mode Select function that allows
the driver to choose between ECO, NORMAL, SPORT S and SPORT S+
driving modes, maximising either the vehicle’s environmental efficiency or its
dynamic abilities.
In ECO Drive Mode, engine power output, throttle opening and air
conditioning are controlled automatically to maximise fuel economy. In
addition to moderate drive force changes, the air conditioning functions
are also adjusted, limiting ventilation losses. At temperatures below 10°C
(for GS 450h) and 3°C (for petrol version) the seat heater switches on
automatically. The air-conditioning changes to recirculation as from 20°C and
23
by turning the dial once clockwise. When selected the meter illumination turns
red and the SPORT S mode is indicated on the 12.3’’ screen.
Available on GS models equipped with the Adaptive Variable Suspension
(AVS), SPORT S+ mode combines the SPORT S mode’s enhanced
powertrain output with coordinated control of the Vehicle’s Dynamic
Integrated Management (Step 5 VDIM) including Adaptive Variable
Suspension (AVS) and Electric Power Steering (EPS). When equipped with
Lexus Dynamic Handling (LDH), also Variable Gear Ratio Steering (VGRS)
and Dynamic Rear Steering (DRS) are included.
When M-range is selected, the driver benefits from the total control of fully
manual gear changes via steering wheel mounted shift paddles. With rapid
up shifting and throttle blipping on down shifts, customers can enjoy the most
direct, sporting driving experience the new GS has to offer.
Enhancing the enjoyment of the new GS’s expanded breadth of driving style
preferences, the ambient illumination of the driver’s instruments changes to
a tranquil blue in ECO mode, whilst switching to red in both SPORT S and
SPORT S+ modes. Switching to SPORT S and SPORT S+ modes in the GS
450h automatically changes the system power indicator into a tachometer.
All these enhance the new GS’ stability and steering rewarding the driver
with the ultimate in sporting driving dynamics. The SPORT S+ mode can be
selected by turning the dial twice clockwise illuminating the meters red and
the SPORT S+ mode is indicated on the 12.3’’ screen.
The Lexus Dynamic Handling (LDH) System
The GS 450h F SPORT can be equipped with the Lexus Dynamic Handling
system, making it the world’s first hybrid vehicle to feature an integrated fourwheel steering system.
In addition, a new Sport-D Control system, activated when SPORT S
and SPORT S+ modes are engaged, enhances the performance of the
GS 350AWD’s automatic transmission. With the gear shift level in D-range,
Sport-D Control automatically shifts down the appropriate gear when the
vehicle approaches a corner and maintains the gear when cornering, making
maximum acceleration available to the driver as he exits the bend.
The leading edge platform technology of the Lexus Dynamic Handling system
offers an integration of Dynamic Rear Steering (DRS), Variable Gear Ratio
Steering (VGRS) and Electric Power Steering (EPS), to coordinate every
aspect of front and rear wheel control and provide agile, sharp and confident
driving behaviour with a more direct response to the driver’s actions.
Monitoring vehicle speed, steering direction and driver inputs, LDH calculates
the optimum angle for all four wheels. Using VGRS to the front and DRS
24
to the rear, the system can independently control both front and rear wheel
steering angles to greatly improve turn-in response, rear grip, vehicle stability
and overall agility when cornering.
The LDH system monitors vehicle speed and yaw rate, steering angle and
speed, and lateral G to calculate the required rear wheel steering input, to
a maximum of 2.0 degrees. At most speeds below 80km/h the front and
rear wheels turn in opposite directions. In certain conditions at speeds over
80km/h, front and rear wheels turn in the same direction.
Further coordinating DRS with VGRS and EPS, the Lexus Dynamic Handling
system will automatically customise the adaptive suspension tuning and active
safety systems to suit road conditions, vehicle speed and driving style, giving
customers the confidence to fully exploit the new GS’s exceptional driving
performance.

Hybrid Drive system; a revised GS 350AWD, with increased power and
greater efficiency; and the GS 250, featuring a 2.5 litre V6 which is new to
the GS model range.
GS 450h
Reinforcing the company’s commitment to the future of full hybrid drive
technology, the new GS 450h is equipped with a second generation Lexus
Hybrid Drive system.
Incorporating comprehensive improvements to every aspect of its full
hybrid powertrain, the new GS 450h offers significant reductions in fuel
consumption and CO2, NOx and PM emissions, with no loss of performance.
3
With a total system power output of 254kW/345DIN hp, the GS 450h
will accelerate from 0-100km/h in 5.9 seconds and has a maximum speed
of 250km/h. Conversely, fuel consumption has been reduced by 23% to
5.9l/100 km, and CO2 emissions have fallen to 137g/km.
Lexus Hybrid Drive System Architecture
As with every Lexus hybrid vehicle, the new GS 450h is a full hybrid capable
of operating in petrol or electric modes alone, as well as a combination of
both. Its Lexus Hybrid Drive system features an ultra-smooth running,
213kW/290DIN hp, 3.5 litre V6 petrol engine mated to a compact, highoutput, water-cooled permanent magnet electric motor, the two powerplants
driving the rear wheels both independently and in tandem, as appropriate.
In addition to the petrol engine and electric motor, the new GS 450h’s hybrid
drive system further comprises a generator, a high-performance nickelmetal hydride battery, a power split device which, via planetary reduction
gears, combines and re-allocates power from the engine, electric motor and
generator according to operational requirements, and a compact power
control unit to govern the high speed interaction of the system components.
3.5 Litre Atkinson cycle V6
Adapted specifically for the hybrid powertrain, the 3.5 litre, DOHC, V6
petrol engine benefits from several technical improvements. It adopts the
Atkinson cycle to optimise the fuel-efficient benefits of Lexus Hybrid Drive.
Not all European markets introduce all three powertrains. For more information please contact your national PR
Manager
27
With conventional four-cycle petrol engines, there are times when ‘fuel
enrichment’ becomes necessary, cooling exhaust gases to prevent
degradation or destruction of the catalytic converters. Because the intake
valves close late in an Atkinson cycle engine, compression is delayed. This
creates a high expansion ratio for less compression, reducing intake and
exhaust energy losses and converting combustion energy to engine power
more effectively. As a result, the exhaust temperature is lower than that of
conventional engines.
Further reductions in fuel consumption have been achieved through a high
physical compression ratio of 13:1, a new, mid-port intake tumble generator
and the adoption of next generation D-4S direct injection technology.
D-4S is the latest evolution of Lexus’ stoichiometric, 4-stroke, direct injection
technology. With one injector installed in the combustion chamber and a
second mounted in the intake port, it combines the strengths of both direct
and port injection, realising optimum engine efficiency throughout the power
band and improving torque across the rev range, whilst minimising fuel
consumption and emissions.
The new GS 450h’s next generation D-4S system features new slit-type
injector nozzles with a modified port shape, a higher fuel pressure for
more efficient combustion, and idle port injection for improved NHV
characteristics.
28
Engine noise, vibration and friction has been lowered through the adoption
of lightweight chain technology, a piston pin offset change and a reduction in
the number of drive belt reinforcement ribs.
In addition, engine durability has been improved through the removal of
all external oil lines, and environmental performance enhanced by a newspecification catalyst which contains greatly reduced levels of precious metal.
Additional Hybrid System Component Improvements
The cooling performance of the hybrid system’s Power Control Unit (PCU)
has been improved through the adoption of dual cooling paths and a singlepiece, integrated DC/DC converter.
System control has been enhanced. The PCU boosts motor drive voltage
to a maximum 650V in SPORT S mode and limiting it to a maximum of
500V in ECO mode to provide a more environmentally–friendly driving
performance.
The electric motor features lighter mounts and a reduction in friction. And
the system’s regenerative braking operation range has been expanded,
contribution to further improvements in fuel efficiency.
In addition, the battery layout has been redesigned; a new stacked
configuration maximising luggage space.
GS 250
Expanding the powertrain line-up to offer further improvements in fuel
economy and emissions, a 2.5 litre V6 petrol engine is available for the first
time in the Lexus GS model range.
The V6 features D-4S direct injection, and Dual VVT-i (Variable Valve
Timing-intelligent) to both intake and exhaust camshafts, enhancing engine
performance.
It develops 154 kW/209 DIN hp at 6,400rpm and 253Nm of torque at
4,800rpm, accelerating the GS 250 from 0-100km/h in 8.6 seconds and
giving a maximum speed of 230km/h. Fuel consumption is 8.9l/100 km,
and CO2 emissions 207g/km.
The new 2.5 litre V6 is mated to Lexus’ ‘6 Super ECT’ close-ratio 6-speed
automatic transmission, which features a sequential manual shifting mode.
As with the 3.5 litre engine, it incorporates numerous technologies including
faster shift speeds, earlier torque converter lock-up and downshift throttle
blips- to support the range of driving modes available through the Drive
Mode Select system.
29
GS 350AWD
The 3.5 litre V6 petrol engine of the new GS 350AWD has been revised to
lower both fuel consumption and emissions.
The advanced V6 features D-4S direct and port injection, and Dual VVT-i
(Variable Valve Timing-intelligent) to both intake and exhaust camshafts,
significantly enhancing engine performance and reducing fuel consumption.
It develops 233 kW/317 DIN hp at 6,400rpm and 378Nm of torque
at 4,800rpm, accelerating the GS 350AWD from 0-100km/h in
6.3 seconds and on to a maximum speed of 190km/h. Fuel consumption
has been reduced to 10.2 l/100 km, and CO2 emissions are 237g/km.
The ‘6 Super ECT’ close-ratio 6-speed automatic transmission features a
sequential manual shifting mode. It incorporates numerous technologies
including faster shift speeds, earlier torque converter lock-up and downshift
throttle blips- to support the range of driving modes available through the
Drive Mode Select system.
The GS 350AWD’s electronically controlled all-wheel drive system is
designed to improve traction and grip by automatically varying front-to-rear
torque balance from 50:50 to as much as 20:80, providing exceptional
stability under all driving conditions.

The new Lexus GS is comprehensively equipped with the most
technologically advanced pre-emptive, active and passive safety and driver
assistance systems available on the market today.
An Advanced Pre-Crash Safety (PCS) system incorporates a Driver
Monitor Camera. PCS pre-emptively optimises front seat belt and
emergency braking systems to help reduce collision damage and injury.
A complementary Adaptive Cruise Control (ACC) system, now available
on the GS 450h, functions at all speeds down to 0km/h.
The GS features the latest, Step 5 generation of Lexus’ state-of-the-art
Vehicle Dynamics Integrated Management (VDIM), which now integrates
the newly developed Lexus Dynamic Handling (LDH) system.
Additional active safety features include a Lane-Keep Assist (LKA) system,
a Blind Spot Monitor (BSM) system, the Lexus Night View system, and a
Head-Up Display (HUD) with an expanded content menu.
The new Lexus benefits from no less than 10 airbags, and rear seatbelt
pre-tensioners are fitted as standard. Intelligent Adaptive Front Lighting
(I-AFS) enhances visibility through bends, whilst the new GS’s front bumper,
cowl and corrugated sheet bonnet have been carefully designed to offer
enhanced pedestrian protection in the event of a collision.
PREVENTIVE SAFETY
Advanced Pre-Crash Safety (PCS)
The new GS is equipped with a sophisticated, Advanced Pre-Crash Safety
(PCS) system that can help reduce collision damage and injury. The PCS
system features a millimetre-wave radar sensor, operating within a 20 degree
scanning radius to detect obstacles in front of the car, even during cornering.
33
Via numerous sensors, a pre-collision system computer monitors vehicle
speed, steering angle and yaw rate inputs to help determine in advance
whether an impending collision is unavoidable.
If there is a high possibility of a collision, PCS will alert the driver via both
a buzzer and a warning on the multi-information display, activate the
Pre‑Crash Seatbelt pretensioners to retract all slack from the front belts and,
when he begins to brake, provide Pre-Crash Brake Assist to supplement his
own braking effort.
In addition, PCS implements a close interaction between the Variable Gear
Ratio Steering (VGRS) and Dynamic Rear Steering (DRS) incorporated
within the GS’s Step 5 Vehicle Dynamics Integrated Management (VDIM)
system, improving the vehicle’s response to the driver’s emergency steering
inputs to increase the chances of avoiding the obstacle.
If the driver does not brake and a collision is inevitable, Pre-Crash Brake will
automatically apply the brakes to reduce impact speed.
PCS has been revised in the new GS. The timing of brake intervention has
been increased from 0.8 to 1.2 seconds before anticipated impact, both
improving the chances of avoiding a frontal collision and, in the event of
impact, lowering the collision speed by about 15km/h to greatly reduce
vehicle damage.
34
Driver Monitor Camera
The Advanced Pre-Crash Safety system also incorporates a Driver Monitor
Camera. The system employs two near-infrared LEDs and a CCD camera
built into the top of the steering column. Monitoring various aspects of the
driver’s face including the degree of eye opening, the system is able to
determine if the driver’s eyes are closed. If this is the case when there is a
danger of collision, the timing of the Pre-Crash warning sequence is brought
forward to alert the driver in good time.
All-speed Adaptive Cruise Control (ACC)
Complementary to the PCS system, the new GS features an Adaptive
Cruise Control (ACC) system. The system offers two modes: constant
speed control, and vehicle-to-vehicle distance control. Operational at
speeds over 50km/h, the constant speed control functions in the manner of
a conventional cruise control system.
Capable of differentiating between vehicles directly ahead of the Lexus and
those in an adjacent lane, the vehicle-to-vehicle distance control system
employs the PCS millimetre-wave radar sensor, allied to constant speed,
decelerator, follow-up and accelerator controls, to automatically slow the
GS, match the speed of the vehicle in front and, once the road is clear ahead,
accelerate to the previously selected cruising speed.

Exclusive to the GS 450h, ACC is now capable of operating at all speeds
down to 0km/h. After a complete stop, and then restart of the preceding
vehicle, the GS’s driver need only press the accelerator briefly to reactivate
ACC’s tracking of the car in front.
ACTIVE SAFETY
Vehicle Dynamics Integrated Management (VDIM) Step 5
The new GS features the latest, Step 5 generation of Lexus’ state-of-theart Vehicle Dynamics Integrated Management (VDIM) system, to enhance
performance, traction control and vehicle stability.
With comprehensive status data provided by sensors throughout the vehicle,
VDIM integrates the GS’s Electronically Controlled Brake (ECB) fourwheel independent braking, Anti-Lock Brakes (ABS), Electronic Brakeforce
Distribution (EBD), Traction Control (TRC) and Vehicle Stability Control
(VSC) active safety systems with the Electronic Power Steering (EPS),
Variable Gear Ratio Steering (VGRS), Adaptive Variable Suspension (AVS)
and –for the first time- Dynamic Rear Steering (DRS) systems.
Whilst the current generation GS’s VDIM system can help restrain vehicle
yaw and roll motion through control of the AVS and VGRS, the newly
developed Step 5 incorporates the Lexus Dynamic Handling (LDH)
system. This enables the VDIM system to control the steering angle of all four
wheels, achieving the ideal slip angle to help govern the lateral motion of the
36
vehicle for added stability when, for instance, there is a risk of understeer or
oversteer when cornering, or when braking on a road surface with differing
levels of grip between the left and right wheels.
By the application of integrated control of all the elements related to vehicle
movement, including motor torque, brakes and steering, VDIM not only
optimises the activation of braking, stability and traction control systems, but
is also able to further improve the overall kinetic performance of the vehicle.
Moreover, whereas conventional safety systems are only activated
immediately after a limit of the vehicle’s performance envelope has been
reached, VDIM activates control before that limit is realised. As a result, the
limits of the vehicle’s performance threshold have been expanded, whilst
offering smoother vehicle behaviour at this threshold through less obtrusive
intervention and, hence, a more pleasurable drive.
Lane-Keep Assist (LKA) system
With lane marker detection provided by an on-board camera, the new GS
is equipped with a Lane–Keep Assist (LKA) system to help keep the driver
from drifting out of his lane.
Now offering smoother steering corrections, the system calculates the
steering torque input required based on the results of lane-marker detection,
and automatically generates appropriate torque.
Blind Spot Monitor (BSM) system
The Blind Spot Monitor (BSM) system uses radar devices mounted on the
corners of the rear bumper to detect overtaking vehicles in adjacent lanes.
Blind Spot Monitor
Operating if the GS’s speed is greater than 40km/h and the relative speed
of the two vehicles is less than approximately 28km/h, the system activates
a warning via an indicator lamp in the outer door mirror. If the turn signal
indicators are operating at the time, the warning lamp will flash at a faster
4.0Hz frequency than the 1.7Hz of the turn signal lamps to alert the driver.
Lexus Night View system
The Lexus Night View system combines a windscreen head-mounted
near-infrared camera and infrared LED lamps mounted within the headlight
clusters with a Night View ECU to display an image of the road ahead on
the GS’s 12.3” centre console display screen.
Head-Up Display
The system will operate at speeds of between 15 and 80km/h, displaying an
area up to 200 metres in front of the vehicle.
Head-Up Display (HUD)
White readouts on the Head-Up Display project key GS driving data into
the driver’s line of sight on the base of the windscreen, including vehicle
speed, turn-by-turn navigation, audio, Adaptive Cruise Control and
37
Pre‑Crash Safety system status. For the first time on a Lexus, the display also
now includes tachometer information.
The HUD’s white readouts use high-intensity LEDs to provide ample clarity
and visibility, and it is extremely easy to use. Pressing and releasing the HUD
main switch turns it on and off cyclically. The display position can also be
adjusted, as can light intensity, which may also be adjusted automatically to
the ambient light.
Adaptive Front-lighting System (AFS) with Automatic High Beam
The new GS features an Adaptive Front-lighting System (AFS), which
automatically swivels the headlamp beam, helping to illuminate a bend as
the driver steers into it.
The new system features a more advanced swivel control, increasing the
swivel angle of one headlamp only at low speeds to enhance intersection
visibility, whilst swivelling both beams at higher speeds for improved visibility
and reduced glare for oncoming vehicles.
Through the combination of AFS and Dynamic Rear Steering (DRS), swivel
control has now been developed to monitor front and rear wheel steering
angle difference, as well as vehicle speed.
38
The headlamps also feature an Automatic High Beam system. A camera
located in the inner mirror detects light sources in front of the new GS
-including the headlamps of oncoming vehicles, the tail lamps of a vehicle
ahead and street lighting- and the system will automatically switch the high
beams on and off accordingly, obviating the need for manual operation of
the dimmer switch.
Emergency Brake Signal
The new GS features an Emergency Brake Signal system. Based on
information from the acceleration sensor, wheel speed sensor and brake
pedal switch, the system monitors vehicle status and the driver’s brake
operation, automatically flashing the brake lamps during emergency braking.
By adopting an LED light source, the response speed of the brake lamps has
been significantly improved, alerting the driver behind as quickly as possible
to help prevent rear-end collisions.
Tyre Pressure Monitor (TPM)
A Tyre Pressure Monitor (TPM) can detect a loss of pressure in one or
more tyres. Notifying the driver via a dashboard mounted warning light, the
system will highlight any tyres affected by low pressure, indicating the current
pressure.
PASSIVE SAFETY
Body Structure
Reflecting the stringent car-to-car impact compatibility standards unique to
the Lexus marque, the new GS has been created with the express aim of
achieving class-leading safety in full-frontal, offset, side-on and rear collisions.
The comprehensive use of high- and ultra-high-tensile steel within the body
structure optimally transfers and disperses impact load, minimising cabin
deformation during a collision and maintaining space for the occupants.
Particular attention has been paid to side impact protection, with ultra-hightensile steel adopted for rocker outer reinforcement, the rear door impact
beam sheet thickness increased, and Lexus’ first use of hot press sheet steel
in the construction of the B Pillar.
During the die moulding of hot press steel, firing and quenching occur at
the same time as pressing, both enabling the creation of profiles that would
be difficult to form with cold sheet steel, and increasing the strength of the
material itself.
Pedestrian Protection
The new GS’s front bumper, cowl and corrugated sheet bonnet have been
carefully designed to offer enhanced pedestrian protection in the event of a
collision.
39
The bead height and pitch of the corrugated bonnet design have been
optimised with a new, thinner design. The frontal bonnet structure has been
designed to easily deform on contact with a pedestrian’s upper legs, and a
gap between the bonnet and the top of headlamps helps reduce the force
of a head impact.
Impact absorbing materials built into the front bumper help reduce the load
applied to a pedestrian’s legs. And the front wings incorporate a new, head
impact alleviating structure.
Both the cowl panel area and cowl louvre adopt easily deformed structures
with deformation controlled by the use of different sheet thicknesses.
Airbags
The Lexus GS benefits from 10 airbags; two-stage Dual Supplementary
Restraint System (SRS) front airbags, both driver and front passenger knee
airbags (the latter installed in the glove box door), front and rear side airbags,
as well as both front and rear side curtain airbags.
The advanced, Supplementary Restraint System controls variable-force front
airbags for both driver and front passenger. Sensors determine the severity
on an impact and, hence, the force with which the airbags are deployed.
