Now that the snow is gone, Porsche has taken future vehicle testing back to Germany. The upcoming next-generation Porsche 911 Turbo has been spotted this time around the Nürburgring and the Autobahn.
Compared to the standard 911 prototypes, that we have shown you before, the new 911 Turbo features wider fenders, air intakes in the rear fenders, and a rear bumper with integrated exhaust pipes.
As we have mentioned before, the new 911 Turbo is expected to produce up to 600bhp. World debut for the new 911 range is at the Frankfurt Auto Show in September. The Turbo variant will likely be introduced in late 2011 or in early 2012.
