THE fastest, most powerful, four-door Bentley model ever will make its global debut at next month's Geneva Motor Show.

The new Flying Spur is powered by the Crewe-based brand's 6.0-litre, twin turbo W12 engine, coupled to a ZF eight-speed transmission.

And with 616bhp on tap it boasts more power than any other Bentley four-door in history.

A 14 per cent improvement in the power-to-weight ratio over the outgoing model delivers a 0-60 mph time of 4.3 seconds and top-speed of 200 mph, the power delivered via all-wheel drive with a 40:60 rear-biased torque split.

The newcomer also includes 600 new parts, with only the sun visors, grab handles, armrests and some of the front console and controls carried over from the previous generation.

Available as both a four or five-seater, the Flying Spur comes with the promise of more comfort and refinement including the latest in touchscreen infotainment like mobile connectivity including Wi-Fi, a rear seat entertainment suite and a new hand-held remote.

Style-wise the car's lower roof line, deeply sculpted panels, precise feature lines and a muscular rear haunch give the Flying Spur a more aggressive stance than before, while LED daytime running lights, dipped headlamps and tail lights highlight the front and rear profiles.

And weight savings in the body structure and throughout the car mean that the Bentley is 50kg lighter than the first generation car, despite the stronger structure.

Bentley chairman Dr Wolfgang Schreiber said: "The new Flying Spur is the ultimate luxury performance sedan.

"Our engineers have worked tirelessly to ensure that the Flying Spur is the perfect combination of power, comfort, refinement and hand-crafted quality."
