General Motors Co. says its new Buick Avista concept coupe “stretches the boundaries” of what’s possible for the luxury marque. The carmaker unveiled the stylish 2+2 coupe Sunday night in Detroit.

The sporty Avista rides on GM’s rear-wheel-drive Alpha platform, which also carries the Chevrolet Camaro sports car and Cadillac’s ATS and CTS models.
