The 911 GT3 RS gets an engine upsize
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.
