After being spied during some brake testing in the European Alps only two weeks ago, the Bentley GTC Speed has been caught yet again, this time at the Nürburgring race track during some hi-speed testing.

Much like the Continental GT Speed, the facelift GTC Speed will feature an aggressive front fascia, a vented hood, and new headlights. The back of the Bentley->ke15 will get spruced up with a new trunk-mounted spoiler, slimmer taillights, and a revised exhaust system. This particular prototype caught testing is also sporting a new set of bigger wheels, so we expect they will find their way to the production version as well. Adding to the list of new features will be some new seats and an updated dash with a new sat navigation system.

The powerhouse under the hood is still being kept under wraps, but we expect to find a twin-turbo 6.0-liter W12 engine with a greater output than the current 600 HP. That power will be transferred through an all wheel drive system and transformed into a 0-60 mph sprint time of under 4.5 seconds. Since the future GTC Speed will be lighter than the current model, we expect greater fuel efficiency as well.

Expect the facelift Bentley Continental->ke3108 GTC Speed to debut by the end of 2011, with sales set to begin in early 2012.
