Bentley put the drivetrain from the Continental GT Speed into the Convertible, creating what it has proclaimed as the fastest four-seat drop-top in the world. Bentley estimates that this car has a top speed of 202mph, which makes it 3mph slower than the GT Speed coupé but makes it faster than the old Bentley Speed Convertible by 7mph.
The car is equipped with the twin turbo 6.0-litre W12, enabling the car to have an output of 616bhp and 590lb ft. As a result, the car can accelerate from zero to 60mph in 4.1 seconds. The torque is available from 2000rpm and persists until 5000rpm. It can reach 100mph in 9.7sec. When the engine is used in the Convertible, the fuel economy improves by 15% to return 19mpg. Just like the Speed GT, the suspension was lowered by 10mm compared to the regular GT.
This is due to its stiffer bushes, upgraded anti-roll bars and modified air springs and dampers. The steering was reworked to offer better feedback. The convertible’s increase in top speed wasn’t the result of many improvements in aerodynamics in order to boost downforce. According to Bentley, a soft lip on the bootlid is sufficient for maintaining the car on the road.
Additional external improvements include dark chrome air intakes and radiator grille, a set of 21–inch wheels (which are offered just on Convertible), and bigger tailpipes with rifled interiors. The interior of the car gets a Mulliner spec trim, with its distinctive quilted diamond pattern leather, together with dark aluminium through the dash. Bentley offers carbonfibre as an option. It will begin selling next summer. Bentley has yet to release the official pricing but it’s likely to cost about £164,000, which represents a premium of around £15,000 over a regular GT Convertible. It’s likely to have its first public debut later this month at the Detroit motor show.
