Pagani Zonda R

The Pagani Zonda R is a track day car built by Pagani on the Zonda, which is not road legal. Sources disagree on its debut: Wikipedia gives the 2007 Geneva Motor Show, while Pagani and Supercars.net date its presentation to 2009. Although it shares much of the Zonda shape, it is almost entirely new, sharing only 10 percent of the Zonda F components. Its 6.0 litre AMG-built engine, taken from the Mercedes-Benz CLK-GTR and modified, produces 750 PS at 7,500 rpm and 710 N.m of torque and is mated to an Xtrac 6-speed sequential gearbox. It has a claimed top speed of 375 km/h, and on 30 June 2010 Pagani claimed a production-based car record at the Nürburgring of 6:47, ahead of the Ferrari 599XX. Fifteen Zonda Rs were produced, along with five Zonda Revolucion cars and the prototype.
