The 911 GT3 RS gets an engine upsizeIn the realm of super sports cars, few are as iconic and as successful as Porsche is with their 911. Now after nearly 50 years, Porsche gives their thoroughbred, the 911 GT3 RS, the largest ever displacement engine in its history at 4 liters.
Limited to 600 vehicles worldwide, the 911 GT3 RS 4.0 brings together in a sports car the attributes that have made the Porsche 911 GT3 a consistent winner on the race track and a coveted icon on the road. The motorsport-derived 4.0-liter engine also features the highest per-liter output with a ratio of 125 hp/l from a naturally aspirated Porsche flat-six engine. The engine uses forged pistons, titanium connecting rods and a crankshaft from the 911 GT3 RSR race car. As such, the 911 GTR RS 4.0 achieves its maximum power of 500 hp at 8,250 rpm with a maximum torque of 339 lb-ft at 5750 rpm.
As with any production 911 of late, the GT3 RS 4.0 was tested and honed at the famed Nürburgring-Nordschleife, lapping the 20 kilometer course in 7 minutes and 27 seconds.
