2013 Bentley Continental GT Speed Convertible: First Photos

We have the first photos of the 2013 Bentley Continental GT Speed Convertible ahead of a reveal at the 2013 Detroit Auto Show. Bentley hasn’t done the official reveal for the GT Sports Convertible yet, so all we have are the first photos in all their purpleness (although the DVLA thinks this particular Bentley is black). Under the skin we expect the same W12 with 616bhp and 590lb/ft of torque which is enough, certainly in the tin-top GT Speed, to get the monster Bentley to 62mph in 4.2 seconds and on to 205mph.

The new Calais sits at the top of what Holden describes as an “extensively upgraded Commodore” range, with right-hand-drive Australian sales set to get underway in June.
