Featuring a new front bumper design with larger side grilles. Together with a dedicated mesh design for the upper and lower grilles, this gives the GS a stronger appearance, reinforcing its wider track and sportier stance.

The new GS features a drive mode select function that lets the driver choose between Eco, Normal, Sport S and Sport S+ driving modes, designed to maximise the car’s environmental efficiency or its dynamic performance.

In Eco mode, engine output, the degree of throttle opening and gear selection are all automatically modulated to achieve the best fuel efficiency in all driving conditions. The air conditioning temperature, airflow volume and activation of the seat heaters are also controlled, further reducing fuel consumption.

In Sport S mode, engine speed and throttle responses are adjusted to give a more engaging driving experience. Switching to Sport S+ combines the enhanced powertrain output of Sport S with co-ordinated control of the GS’s Vehicle Dynamics Integrated Management system. This includes the AVS and Electric Power Steering, plus, where fitted, the Lexus Dynamic Handling system, Variable Gear Ratio Steering and Dynamic Rear Steering, to give a complete package of sports driving dynamics.

Switching to Sport S+ mode automatically increases the difference between inner and outer shock absorber damping when driving through corners, further reducing vehicle roll. At the same time, the Variable Gear Ratio Steering automatically reduces the steering gear ratio by about 10 per cent, while the Electric Power Steering increases steering assist torque by about four per cent. These measures combine to minimise body roll, sharpen handling and optimise steering feel.

The F Sport will be available to purchase in the UK and across Europe in 2012.
