Bentley unveils new Continental GT Speed Convertible at NAIAS

Said to be the world's fastest four-seat convertible, the impressive Bentley Continental GT Speed Convertible made its debut at the North American International Auto Show in Detroit.

The beautiful blue, topless luxury sedan looks sedate and content sitting on its podium in Detroit, but as earlier reported, this deceptively calm convertible has a 6-liter W12 engine under that hood that puts out 616 bhp and holds a top speed of 202 miles per hour.

The dark-tint grille work and 21-inch alloy wheels give the car a distinct look from its sedan counterparts, making sure everyone knows that you're in the GT Speed Convertible and not just any old Bentley. As a sibling of the GT Speed shown at the LA Auto Show, this one shares the same muscular underpinnings and track-ready build with its zero to 100 time of 9.7 seconds.

All the speed is thanks to the engine's design, which allows peak torque at only 2,000 rpm, putting all 590 pound feet down very quickly and holding that output until 5,000 rpm. Adding in the 8-speed transmission means that it's easy to keep that rev range.

So don't let the sedate repose on the NAIAS floor fool you. This beauty is a monster begging to be tamed on the open road.

The interior is as plush as any Bentley owner can expect. Soft leather seating and a well-appointed dash greets the occupants. Room in the back is limited, but two adults can sit if they aren't over-sized. Boot space is limited when the top is down, of course. All to keep the GT Speed Convertible small and nimble in compliance with its race-style performance.
