Crew, England - Bentley will debut the Continental Flying Spur and Continental Flying Spur Speed at the London Motor Show later this month, the car maker has announced.

The 2009 Flying Spur has undergone a subtle evolution with changes to the front and rear design. The grille is upright with a bolder lower air intake accentuating the distinctive Bentley profile, while a new rear bumper gives a sleeker and more aggressive appearance.

The 552 hp car also offers more comfort with a comprehensive range of noise-absorbent measures including acoustic glazing, the car maker said.

Customer personalisation has been highlighted with an enhanced choice of chrome inlays. In addition, seat piping, a traditional Bentley feature, has also been introduced with two new hide colours.

Joining the Continental Flying Spur in London is the 600 hp Flying Spur Speed. Inspired by Bentley's legendary Speed models that first appeared in 1923, the Flying Spur Speed is distinguished by unique design cues which underline its performance credentials, including dark-tinted radiator and air intake grilles, wider rifled exhaust tail pipes and 20-inch multi-spoke alloys.

Both Continental Flying Spur models can be specified with Adaptive Cruise Control (ACC). The ACC uses a long-range radar sensor, mounted in the lower front grille, to monitor the road ahead for other vehicles.

When a slower moving vehicle is detected, the system automatically adjusts braking and acceleration to maintain a time gap, as selected by the driver. (dpa)
