Spy Shots: New 2013 Porsche 911 Turbo Shows Off its Aero Bits

The next Porsche 911 will make its world premiere in base trim at the forthcoming Frankfurt motor show this September, but this will only be the first chapter of the 991 saga as the Stuttgart-based firm plans to create an entire range of sub models.
The 911�s lineup will eventually grow to include numerous body styles such as coupe, convertible, Targa and speedster models as well as a variety of standard and limited production versions ranging from the entry level Carreras in two- and four-wheel drive layouts to the GT-spec track racers and the almighty Turbo, which our spies caught testing in Germany.
