The De Tomaso Longchamp is a grand tourer introduced at the Turin Motor Show and produced in Italy from 1972 to 1989. It was sold as a 2-door coupe or convertible with rear-wheel drive and a front-mounted engine. The Longchamp was derived from the Deauville model. It used a chassis with a shorter wheelbase, the same suspension, engine and transmission. The Deauville and Longchamp were the only production cars with front-mounted engines produced by De Tomaso. In total, only 409 examples were produced.
The car was powered by a 5.8-litre V8 engine with 330 hp (246 kW), which was mated to a 3-speed automatic (standard) or 5-speed manual (only 17 examples were produced) transmission. The official top speed was 240 km/h (240 mph). The Longchamp had power-assisted steering and ventilated disc brakes front and rear. The interior of the car was almost entirely upholstered in leather.
