Video: Porsche 991 Turbo and GT3 Caught Testing

The next-generation 911 GT3 and 911 Turbo are waiting for their official unveiling, but unfortunately this won’t happen until March when the GT3 will be unveiled at the Geneva Motor Show, while the Turbo version will arrive a little bit later.

Fortunately for us, the two models were caught testing very hard on the Nürburgring track and, as you can hear in the video, both models sound pretty sweet. They both seem to take their beating pretty well, as they remain glued to the `Ring’s surface like true racecars.

As a reminder, the 911 GT3 is powered by a normally aspirated 3.8-liter flat-six engine with an output of 450 horsepower — a 15-horsepower bump over the current model. On the other hand in the 911 Turbo model’s engine delivers a total of 550 horsepower.

With the extra 100 horsepower, the 911 Turbo will be a little bit faster than the GT3, so for sure this is the most awaited model in the new 991 generation.

Both models will go on sale late in 2013.
