2010 Bentley Continental GTC

Bentley's convertible Continental gets mildly revised front end styling and a new GTC Speed model, shown here. The GTC Speed is essentially a drop-top version of the GT Speed coupe; it has a W12 engine good for 600 hp, 48 more than the standard GTC, and a top speed of 200 MPH -- but only 195 with the top down.
