Alpina B5 Bi-Turbo (2011) launches

The features will be standard on a new 2011 Corvette Z06 Carbon Limited Edition, which Chevy is using to celebrate the 50th anniversary of the Corvette's first 24 Hours of LeMans race.

Despite gains of 42bhp and 37lb ft over the already potent Cayenne Turbo, Porsche claims the Turbo S suffers no drop in fuel efficiency or inferior CO2 output.
