2011 Audi R8 GT, an AW first look

Three years after it burst onto the supercar scene, Audi has unveiled a hard-core version of its R8 called the GT. Based on the existing mid-engine R8 V10 and incorporating aerodynamic, weight-saving and mechanical developments used by the company's R8 LMS GT3 race car, Ingolstadt will build just 333 copies of the new 560-hp four-wheel-drive performance flagship. Pricing has not yet been revealed, but given the extent of the changes to the new two-seater, buyers should expect a hefty premium over the R8 V10's $147,000 price tag when the GT goes on sale in North America.

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.
