Detroit automakers are creating thousands of new jobs amid a sales boom. And as they expand, their suppliers are racing to keep up, adding tens of thousands of new jobs.

At Bridgewater Interiors in Warren, Mich., for example, the pace is intense. Hundreds of union employees scurry to fill a growing list of orders. The factory floor is packed with stacks of foam cushions, seat covers and headrests.

Three years after its bankruptcy, General Motors has had a record year. The company, meanwhile, is hiring again — adding third shifts to meet increasing demand for its cars. But Republican presidential candidates still insist the bailout was a mistake.

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.

China has announced that it will increase duties on some U.S.-made vehicles. The Ministry of Commerce in Beijing says it will levy "anti-dumping" duties on all U.S. imports with engines larger than 2.5 liters. It's just the latest volley in an ongoing tariff war with China.
