Michigan Radio: Tracy Samilton

At the 2012 North American International Auto Show, it's clear that the industry's love affair with alpha-numeric designations hasn't waned. There's the ATS, the 700C, the MKZ. Now comes the CTX, a new line of Craftsman riding lawn mowers. They are fast, powerful and loaded with amenities.

"Everybody knows that Detroit's the national stage for cars — Motor City is where autos come from. So this show made perfect sense to come here and launch the tractor," says Onney Crawley, Craftsman's director of brand management for lawn and garden.

This year's auto show in Detroit could set the stage for a shake-up in the fiercely competitive — and hugely profitable — luxury car scene. That's because there's a new kid on the block, and its name is Cadillac.

The General Motors company says its new small, high-performance ATS will allow it to compete for the first time with Audi, Mercedes-Benz and BMW. But getting a brand-new luxury car like the ATS ready for market can be a grueling process.
