The new Continental GT Speed Black.

A convertible version is also offered.

The Continental GT's (almost comically large) W12 engine now produces a healthy 633 horsepower and builds a mountain of torque.

With a successor planned for 2018, the now 11-year-old current Continental model is likely nearing its zenith.
