2015 Porsche 911 GT3 Coupe

Porsche launched the RS version of the 991 GT3 at the Geneva Motor Show in 2015. Controversy strikes: like the GT3, the new RS has an automatic gearbox and four-wheel steering with the wide body of the Turbo.

This limited edition model is a naturally aspirated 4.0-liter flat-six engine delivering 500 horsepower at 8250 RPM and with torque of 338 pound feet with a maximum top speed of 193 miles per hour. Equipped with Porsche Doppelkupplung (PDK) as standard, the 0-60 miles per hour time is 3.3 seconds. That's 0.7 seconds faster than its predecessor. The transmission is essentially two gearboxes in one and thus requires two clutches. Manual operation is based on the established motorsport principle: back to ship up, forward to shift down. The interior includes full bucket seats based on the carbon seats of the 918 Spyder. Motorsport technology includes the front wheel arch air outlets of the lightweight carbon fenders, with 12 slats, providing an efficient exit for the air drawn into the front wheel arches.

Another unique characteristic of the new GT3 RS is the surface contouring of its lightweight magnesium roof and carbon luggage compartment lid. The carbon rear lid has wing uprights in forged aluminum and a rear wing, also made from carbon. With its wider track, a 4 inches longer wheelbase and rear axle steering along with 21-inch rear wheels, which are standard. The Nurburgring Nordschleife time is 7 minutes and 20 seconds.
