Porsche has upgraded its 911 GT3 R race car for the 2013 season.
For starters, the GT3 R, based on the 997-generation 911, receives wider fender flares front and rear. This means that the successful customer racer, fielded in GT3 classes, looks considerably brawnier than its predecessor. According to Porsche, the new aerodynamics generate “substantially more downforce,” allowing for higher cornering speeds and later braking points. The wider track and the adapted wheels provide additional improvement in traction.
Ever since its launch in 2010, customer teams around the world have embraced the 911 GT3 R. In 2012, Porsche customer teams raced the 500-horsepower production-based machine in 131 races, won 41 of them and clinched numerous championships.
For 2013, Porsche Motorsport's modified aerodynamics extend to the front bumper panels, all fenders, the sill covers, the rear panel and underbody with rear diffuser; all received further fine-tuning in the wind tunnel. Porsche enlarged the rear wing to the width of the car and repositioned it to work best with the redesigned body.
The suspension also underwent modifications. The track of both the front and rear axle grew by 50 millimeters. The width of the front rims is now 12 inches instead of 10.9. The wheelbase of the latest 911 GT3 R increases by 10 millimeters.
Like its predecessor, the 4.0-liter, flat-six engine produces 500 hp. Porsche's six-speed sequential dog ring-type gearbox with pneumatic shift system is operated via shift paddles on the steering wheel.
Porsche is also offering customers a conversion kit to update older 911 GT3 Rs to 2013-spec. The kit is available from Porsche Motorsport for €45,500 (approx. $59,000) plus country-specific value added tax.
