Porsche is ready to go racing at the 2013 seasons of World Endurance Championship (WEC) and the Le Mans 24 Hours with its new car for the season, 2013 Porsche 911 RSR. Porsche's new GT car is based on the current generation 991 and will mark the return of the Porsche factory team to Le Mans after 15 years. Not to forget, this year also marks the 911's 50th anniversary and the new 911 RSR wears a "50" livery on its roof to mark the same.
The 2013 Porsche 911 RSR, based on the seventh generation Type 911, has a wheelbase that is 4 inches longer than last year's model. The MacPherson strut from the previous model has been replaced by wishbone suspension in the front, while a new, lightweight six speed transmission with paddle shifters is another major improvement. The engine remains the same - 460 HP, 4.0 liter boxer six cylinder unit - but it has been optimised over last season's unit. Other changes include, extensive use of carbon fiber and composite materials throughout the car's construction to save weight and lower the center of gravity. Windows are made from thin, but strong polycarbonate material and a new lithium-ion battery has helped keep down the weight further. Flip through the official images in the gallery below.
