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.

First U.S. Audi TT RS delivered in Fort Worth

Ex Grand-Am driver Don Istook from Fort Worth, Texas, is the lucky customer who took delivery of the first Audi TT RS model on U.S. shores since the 2008 Audi RS4. Istook was one of the 11,500 fans who signed the petition to bring the TT RS here, so it's only fitting that he gets one of the early copies.

Camaro, Sonic fill the Chevrolet stand at SEMA

Custom Camaro and Sonic models lead the way at the Chevroletstand at SEMA this year, with a green electroluminescent Hot Wheels Camaro leading the pack. The paint on the Hot Wheels car was not actually plugged in to an electrical source to make it glow so bright, but it sure seemed like it was. The idea was to get the same metallic finish that shined on the first 1:64 scale Hot Wheels Camaro, one of the original 16 die-casts that debuted from Mattel in 1968.
