Just a few hours ago, we released a set of spy shots for the upcoming Porsche 911 Turbo Convertible, but that wasn’t the only model out for a little test spin today. Our spy photographers have hit the jackpot with images of the 911 GT3 completely stripped of all of its cammo! Compared to the previous prototypes caught testing, this model is still donning the new rear wing and front spoiler. Most of the body’s components will be made out of composites to help reduce the car’s weight by about 180-200 lbs. The biggest mystery regarding the next GT3 is what’s going to be tucked underneath its hood. It is rumored that the next GT3 will get a new 4.0 liter engine and not the 3.8L naturally-aspirated six cylinder found in the current model. Regardless of the engine choice, Porsche has promised an output of about 480 HP. Porsche CEO Matthias Muller also announced that the new GT3 will not use Porsche’s new 7-speed PDK transmission. It will actually come standard with a six-speed manual transmission, with the technologically-advanced, yet less satisfying, PDK transmission set to be available as an optional extra. Expect to see the new GT3 launched later in Summer 2012 when we hope this engine mystery will finally be solved.
