New Bentley Continental goes all environmental

Bentley has revealed a new Continental GT, which goes all green by only having an eight-cylinder engine. Softies.

The new 4.0-litre engine has two turbos, so it's good for 500bhp, but it's 40 percent more economical than Bentley's mainstay 12-cylinder 'W12' engine that has exclusively powered the Conti GT since launch.
