FABSPEED MOTORSPORT | McLaren MP4-12C "Beast of Corsa" (00:55)
The Fabspeed built McLaren MP4-12C "Beast of Corsa". Enhanced with upgraded turbos, a full Fabspeed exhaust setup, and ECU Tune, this McLaren dominated the Corsa Rally and sounds sinister. Here it is putting down 700whp+ on our Dynojet. This MP4 has run the Corsa Rally (winning the Beast of Corsa award), tackled the Tail of the Dragon, and continues to turn heads on the street.
