Porsche has revealed the new Porsche 911 RSR Type 991, which is the new version of the 911 GT3 RSR Type 997. The new Porsche 911 RSR Type 991 made its world premiere at the World Endurance Championship (WEC) at Silverstone, 13-14 April, 2013.
The 2013 Porsche 911 RSR Type 991 is powered by a 4.0-litre flat-six cylinder ‘boxer’ rear-mounted engine which produces 460 hp. The 911 RSR is characterized by its lightweight design and sophisticated aerodynamics – and a special livery to celebrate 50 years of the 911.
The new Porsche 911 RSR Type 991 has a wheelbase longer by 100mm. New wishbone front suspension replaces the McPherson struts used previously. Another new development from Porsche Motorsport is the particularly lightweight racing transmission, whose six gears are selected via paddles on the steering wheel.
Priorities in the development of the new 911 RSR were more evenly balanced weight distribution and low centre of gravity. The front and rear wheel housings, front and rear lids, doors, underbody, wheel arches, rear wing, dashboard and centre console are constructed from this very light and strong material. Moreover, all windows are made of particularly thin and light polycarbonate. Also contributing to the weight reduction is the lithium-ion battery.
