2014 Porsche GT3

The Design 

With over 2,300 sold, the 911 GT3 Cup is the undisputed number one among Porsche motorsport teams. The car competes in prestigious racing events around the globe, including various Porsche Carrera Cups, the GT3 Cup Challenges and the Porsche Mobil 1 Supercup. It also lines up in various GT racing series and endurance races.

Why? Because the 911 GT3 Cup has got what it takes. Specifically, we’re referring to a powerful yet extremely efficient engine and a sequential gearbox; the results of considerable development effort. Then there is the bodyshell construction which is based for the first time on a combination of aluminium and steel and boasts improvements not only in aerodynamics but also in safety – another of our primary obligations.
