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.

Chrysler pushes Saturday service and sees Sunday as the next frontier

Chrysler Group's Mopar parts and service division is ratcheting up efforts to get more dealers to open service departments on Saturday. Starting in January, Mopar will open all of its 20 North American parts distribution centers on Saturdays. In April, Mopar launched Saturday hours for its help desk so dealership service technicians could call with questions about repair issues.

One Lap of the Web: Senna's sweet go-kart

-- Gran Turismo has always included some, uh, unique car choices for its video games. (Sure, the Patent-Motorwagen is significant, but hot-lapping the 1-hp horseless carriage in "Gran Turismo 4" wasn't exactly riveting, unless you used cheats.) So that's why Ayrton Senna's go-kart from the 1978 World Karting Championship should be interesting -- it's nowhere near as fast as his Lotus 97T, but it shows that "Gran Turismo" wasn't kidding when developers said they wanted fans to chart the entirety of Senna's life. Plus, if you make it go 352 mph you can finally stick it to Prost.
