Lexus Europe heeft een officiele persbericht rond de onthulling van de Lexus GS F-Sport uitgebracht (engels):

Lexus to introduce the new GS F SPORT package at SEMA Auto Show
· A bolder, more aggressive and sporty design
· 19’’ staggered-width wheels for additional traction
· Sports-tuned suspension with a more dynamic Adaptive Variable Suspension (AVS) system
· Lexus Dynamic Handling system integrating DRS, VGRS and EPS for even more agile,
sharp and confident driving behaviour
· World’s first hybrid vehicle to feature an integrated four-wheel steering system
· Sports brakes with larger, 356 x 30mm ventilated front discs and an aluminium rotor hat
section for weight reduction and heat deformation prevention
Lexus will reveal the new GS F SPORT package at its press conference on Tuesday, November 1 at
13:30 (Pacific Time) at the SEMA Show in Las Vegas.

Design
Available in Europe across the GS range, the F SPORT package features an exclusive front bumper
design 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.
To the rear, the GS F SPORT features a grey metallic paint finish to the bumper diffuser which for the
GS 450h F SPORT is a combination of grey metallic paint with a chrome plated moulding to the lower
section of the bumper. This further enhances the vehicle’s road presence.
All F SPORT models benefit from a rear spoiler and exclusive, dark premium metallic 19” staggeredwidth
alloy wheels paired with 235/40/19 front and 265/35/19 rear tyres. The wider width wheels
allow not only for a sportier look, but will also help provide added traction.
The interior design features include matching door and seat upholstery (also available in Garnet, a
grade-exclusive colour) combined with 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.

Suspension
The F SPORT package features retuned front and rear suspension systems, supported by Adaptive
Variable Suspension (AVS) to maximise 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.
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.

The AVS system allows the driver to fine tune the GS’s ride characteristics with a choice of two damper
settings; ‘Normal’ damper mode, for everyday driving comfort, and ‘Sport S+’ damper mode, for
improved body control and precise responses to steering input whilst cornering.
In response to driver inputs, vehicle body motion and road surface conditions, AVS activates the
adjustable damping force shock absorbers, automatically adapting the performance of the suspension
at all four wheels independently to fulfil a wide range of specific control functions.
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.

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 driving mode, engine output, throttle opening and gear selection are automatically modulated
to optimise fuel efficiency under all driving conditions. The air conditioning system temperature,
airflow volume and seat heater activation are also cooperatively controlled, further reducing fuel
consumption.

In SPORT S driving mode, engine speed and throttle responses are optimised to allow customers to
enjoy a more engaging driving experience which exploits the full capabilities of both petrol and full
hybrid powertrains.

SPORT S+ driving mode combines the SPORT S mode’s enhanced powertrain output with coordinated
control of the VDIM system (including AVS and Electric Power Steering (EPS) and, when equipped with
LDH, also VGRS and DRS) to reward drivers with the ultimate in sporting driving dynamics

Lexus Dynamic Handling system (LDH)

In addition to the standard suspension enhancements of the F SPORT package, the GS 450h F SPORT is
equipped with the Lexus Dynamic Handling system (LDH), making it the world’s first hybrid vehicle
to feature an integrated four-wheel steering system.

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 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 DRS 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 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, LDH 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.
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 piece rotor has been fabricated in aluminium to both
reduce weight and suppress heat deformation.
