The Porsche 911 GT2 RS is a limited production high-performance sports car made in 2010. As the name suggests, the GT2 RS is a lightweight variant of the GT2 with a modified version of the 3.6 litre flat-six engine. Its low weight of 3,020 lbs was achieved by the extensive use of lightweight materials such as carbon fibre, aluminium and plastic. The 911 GT2 RS is known for its lap time along the Nordschleife of 7:18:00, being over one second faster than the Radical SR3 Turbo and 10 seconds faster than the Porsche Carrera GT.
