Lexus has introduced a new IS 220d Sport model, which uses the same 175 horsepower, four-cylinder common rail diesel unit as the regular IS 220d, but delivers an even more rewarding driving experience.

The principal factor in achieving this is a change in the differential gear ratio in the rear axle, enabling the driver to fully exploit the engine's strong power and torque through the IS's new six-speed manual transmission.

The special character of the £26,925 IS 220d Sport is further reflected in its adoption of Lexus's Vehicle Dynamics Integrated Management (VDIM) system.

This technology constantly monitors a wide range of vehicle performance factors, such as speed, engine torque, braking and steering angle and uses the information to optimise the activation of the anti-lock brakes, electronic brakeforce distribution, vehicle stability control and traction control systems. VDIM also co-ordinates the electric power steering, introducing torque assistance to help the driver use the correct steering angle should the car begin to over or understeer. Whereas conventional active safety systems are typically only triggered once a vehicle reaches the limits of its performance, VDIM engages control before that limit is reached. This means the intervention is less obtrusive and the vehicle handles more smoothly.

The specification emphasises the 220d Sport's qualities with 18-inch alloy wheels and sports suspension. Inside there are sports-style pedals, metal-effect trim details and Cellensia suede-effect upholstery.

The front seats are heated and have eight-way electric adjustment to help each owner achieve the perfect driving position. The Sport also shares a range of luxury features with the IS 220d SE-L model, including climate control air conditioning, cruise control, a 13-speaker audio system with in-dash six-disc CD autochanger, rain-sensing wipers, front and rear parking sensors, smart keyless entry, push-button start, electrically adjustable steering column and memory settings for the driver's seat, steering wheel and door mirrors.
