Bentley has given the GT Coupe its famous 6-liter, 12-cylinder engine but teased out more power than before (567 bhp and 516 lb-ft of torque) and added a new Quickshift transmission that allows double downshifting.

The data-transmission rate will also double (each channel now carries only 64 kilobits a second, which accounts for the jerky pictures that the system produces).

Even under heavy throttle, the upshifts are creamy-smooth, and when the GL350 reaches highway speeds, the transmission slips into a nearly catatonic double overdrive.
