The world's fastest four-seater convertible, the 202mph Continental GT Speed Convertible, has been revealed

Bentley has revealed the world’s fastest four-seater cabrio, the Continental GT Speed Convertible, at the Detroit Motor Show. Under the bonnet is the same 6.0-litre twin-turbo W12 engine that powers the GT Speed coupe, producing 616bhp and 800Nm of torque. 

As a result, Bentley claims the cabrio can do 0-62mph in only 4.4 seconds, 0-100mph in 9.7 seconds and go on to a 202mph top speed with the roof up. That’s a mere two-tenths down on the hard-top from 0-62mph, and 3mph slower overall, but it’s hardly surprising considering that the convertible weighs 175kg more, at 2,495kg. What’s even more impressive is that Bentley claims the car will hit 197mph with the roof down – although a spokesman confirmed that no one at the company has yet been brave enough to try it.

As with the coupe, the convertible benefits from 10mm-lower self-levelling suspension, plus recalibrated steering and stability control. In Sport mode, an uprated version of Bentley’s eight-speed auto box can ‘block shift’ down several gears at once for improved responses, while gearchanges occur at higher rpm and throttle response is also sharpened up.

The addition of the new gearbox and engine management tweaks has also yielded a 15 per cent improvement in efficiency over the previous GTC Speed. This means the drop-top returns a claimed average of 19mpg and emits 347g/km of CO2 – that’s 0.5mpg less and 9g/km more respectively than the coupe.

A subtle makeover will mark out the Speed from the rest of the range, with unique 21-inch alloy wheels (finished in silver or with an optional dark tint). A dark tint is also applied to the air intakes and elliptical tailpipes with a ‘rifled’ finish on the inside. For the interior, the luxurious Mulliner Driving Specification is standard. This includes diamond-quilted leather upholstery, aluminium ‘engine-spin’ trim and the latest Bentley infotainment system, which incorporates a DAB radio, satellite images for the sat-nav and live traffic data. Scuff plates embossed with the word ‘Speed’ are fitted to the door sills, too.

The GT Speed Convertible goes on sale in the UK from late June, with prices starting at £167,900.
