(August 10, 2009) It was reported Monday that Cadillac's next flagship sedan, the XTS, will be built on the Buick LaCrosse platform.

The XTS is due in 2011 as a replacement for both the mid-sized rear-drive STS sedan and the full-sized front-drive DTS. The platform will be wider than the LaCrosse's and fitted for a more luxurious Cadillac ride, according to Automotive News. It's expected that the XTS will offer all-wheel drive.

The XTS continues Cadillac's dramatic makeover, which includes a completely redone SRX crossover on sale now and the jettisoning of the XLR roadster.
Automotive News reports the GM plant in Oshawa, Ontario, is a likely source for the new XTS.

Cadillac has also confirmed that it will build a new small-car range to compete against the BMW 3-Series, although it already offers a 3-Series competitor with the current CTS sedan.
