Cadillac ATS coupe bows at Detroit auto show

Cadillac's ATS range grows into an even stronger BMW 3-series/4-series competitor with the introduction of the coupe model, which marks the first time GM's luxury division has taken the plunge into the compact luxury coupe segment. The ATS coupe's 109.3-inch wheelbase is shared with its sedan brethren, but wears a lot of its own bodywork including a unique roof, doors, fenders, trunk lid and front fascia to not only give the coupe its own distinctive look, but to dress the wider track the coupe gets over the sedan. The ATS Coupe will be the first production Caddy to wear the division's new crest when it goes on sales this summer.
