According to a recent report, Cadillac has decided not to build an estate and convertible version of the upcoming ATS.

The 2013 Cadillac ATS is being billed as a legitimate competitor to the BMW 3-Series and Mercedes C-Class, so it's a tad surprising the company has reportedly axed the wagon and convertible variants.

According to GMI sources, Cadillac believes there are not enough buyers to justify building the proposed models. Despite this, the company will still launch the sedan next summer and a coupe should follow within a year or two.

As we have previously reported, the ATS will ride on the Alpha platform and could feature a turbocharged four-cylinder engine. Rear-wheel drive will be standard, but all-wheel drive is expected to be optional (at least on the sedan).
