Designed by Jan Wilsgard, the Volvo P172 was supposed to be the coupe destined to replace the P1800 in the Gran Turismo segment. It was to have been equipped with the 3-liter, 160-horsepower in-line 6-cylinder engine designed for the future 164 sedan. The lines of the P172 were strongly inspired by those of the Facel Vega. The project never went beyond a full-size maquette, moreover without the interior and the engine.
