As predicted, Buick has revealed a new coupe concept in the shape of the Avista, a 2+2 gran tourer utilizing GM's Alpha platform that underpins the Chevy Camaro and Cadillac ATS and CTS. And before you ask, yes, that body paint, also accented on the 20-inch alloys, is purple (or Dark Sapphire Jewel). Nice touch, Buick. Power comes from a 3.0-liter twin-turbo V6 that sends 400 hp to the rear wheels via an eight-speed automatic transmission.

Evolving the design language that debuted last year on the Avenir concept, the Avista is beautiful to behold with uninterrupted body lines, and a B-pillarless cabin. "There is elegant simplicity in the Avista's surfaces, which speak to the purity of the car's performance, and a timeless beauty that's a hallmark of Buick design," said Bryan Nesbitt, executive director Global Buick Design. "It was designed to capture the spirit of the perfect drive." The Avista's grille sports the marque's new winged tri-shield insignia and its signature wing-shaped lighting forecasts what's to come on future production Buicks.

The cutting-edge cabin features a 3D-printed door, touchscreen controls, widescreen instrument panel display, exposed carbon fiber and aluminum accents, whle the Superior Blue and Mist Gray leather upholstery receives a faded pattern, inspired by waves receding at the beach to emphasize movement and flow (obviously).
