Bentley Motors has revealed a new flagship Flying Spur model, which boasts a touch more oomph and a top speed of 325 km/h. And it's called the Flying Spur W12 S.

The Bentley Flying Spur W12 S features a number of dark styling cues, applied to various elements of the body, from the radiator grille and light surrounds to the rear diffuser.

The new all-wheel drive flagship features increased outputs from its 6,0-litre, twin-turbo W12 engine. Bentley says thanks to "precise calibration and tuning", power is bumped from 460 kW to 467 kW and torque from 800 N.m to 820 N.m.

This increase means that the Flying Spur W12 S is able to achieve a top speed of 325 km/h, making it the fastest four-door Bentley ever. The zero to 100 km/h sprint, meanwhile, is seen off in 4,5 seconds.

Bentley says a "new responsive suspension tune" complements the power increase, and serves to improve handling and traction. Optional carbon ceramic brakes, meanwhile, are available with either red or black calipers.
