It looks like Porsche is testing their 911 GT3 prototypes all over the world, as three different prototypes were caught testing completely undisguised in L’Ametlla del Vallés, Spain, among other locations.
All three prototypes that were caught testing were equipped with a PDK gearbox and steel brake discs (no PCCB) with six and four-piston calipers. We’re assuming that they were also powered by the normally aspirated 3.8-liter flat six engine said to be in the future 911/991 GT3. This engine comes with an output of 450 HP, just a 15 HP increase over the current model. With this power, the GT3 will go close to 200 mph. Customers will have the possibility to choose between both manual or Porsche’s new 7-speed PDK transmission.
The new Porsche 911 GT3 is expected to be unveiled at the 2013 Geneva Motor Show next March. Sales will begin shortly after.
