THE fastest-ever four-door Bentley has been unveiled by the Crewe-based company which describes its luxury, high-powered newcomer as having "extra attitude".

The new Flying Spur W12 S is the first Bentley saloon to have a top speed in excess of 200 mph and features a number of dark styling cues which hint at its new and improved dynamic capabilities.

A suite of black-ware detailing - including Beluga gloss radiator grille and light surrounds - a rear diffuser and optional carbon fibre veneer gives the new model a dramatic and purposeful appearance to match its enhanced performance.

The mighty 6.0-litre, twin-turbo W12 engine has been tweeked to provide more power and torque. Through precise calibration and tuning, engine power is increased from 625 PS to 635 PS (626 bhp) and torque from 800 Nm to 820 Nm (605 lb. ft.). Full torque is available from just 2,000 rpm.

This increase in power means that the Flying Spur W12 S achieves a top speed of 325 km/h (202 mph) - the first four-door Bentley to exceed the 200 mph performance barrier. The initial sprint to 60 mph is achieved in 4.2 seconds.

Power is delivered to the road via an all-wheel-drive system with a 40:60 rear-biased torque split while the suspension has been tuned to improve handling and provide more traction. Carbon ceramic brakes are available as an option with red or black painted calipers.

New styling and trim elements give the car a more "assertive, darker character" according to Bentley.

According to Wolfgang Dürheimer, chairman and chief executive of Bentley Motors:"The Flying Spur W12 S is the ultimate luxury performance sedan. It combines sharper dynamics and an increase in power from our renowned W12 engine with a more assertive exterior and interior design for customers looking for a Flying Spur with extra attitude."

Customer deliveries of the new Flying Spur W12 S will commence at the end of the year.
