Mercedes' AMG Vision Gran Turismo concept was one of the stars of the LA Auto Show, and Cigarette Racing is hoping to make an equally big splash at the 2014 Miami International Boat Show with its 50-foot Vision GT concept. Built in collaboration with AMG, the marine variant of the sexy road-going Vision Gran Turismo is coated in silvery Alubeam paint, with custom matte-black accents.

An all-black cabin sports Alcantara accents and a carbon-fiber dash, four high-def displays and the latest in navigation and audio technology. Power comes from twin 9.0-liter 1,650-hp Mercury Racing V8s, which helps the lightweight boat hit an estimated top speed of over 140 mph. On display now in Miami, the Vision GT is a one-of-a-kind and priced accordingly at $1.5 million.
