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 official target for the digital radio switchover is 2015, but many commentators predict that date will slip as there is a great deal of work to be done before Britain is ready.
