The De Tomaso Longchamp is an automobile which was produced by the Italian automaker De Tomaso from 1972 to 1989.

The Longchamp was developed from the De Tomaso Deauville four-door sedan, using a shorter wheelbase chassis with the same suspension, engine and transmission. The two models were the only front-engined production cars produced by De Tomaso. The Longchamp was first exhibited at the 1972 Turin Motor Show and was initially offered only as a two-door 2+2 coupé. It was designed by Tom Tjaarda of Ghia and was influenced by his previous Lancia Marica prototype. The taillights were the same units as were used for the Alfa Romeo 1750/2000 saloon.

The Longchamp featured a long hood to accommodate a 351 in³ (5766 cc) Ford Cleveland V8. The 351 Cleveland, a popular engine in late 1960s Ford "muscle cars," was the same as that used in the Pantera. It produced 330 hp (246 kW) and gave the Longchamp a 240 km/h (149 mph) top speed. The engine power was later reduced to 270 hp (200 kW). The standard gearbox was a 3-speed Ford C-6 Cruise-o-Matic automatic gearbox, however around 17 cars were equipped with a 5-speed ZF manual gearbox. The suspension was independent front and rear with coil spring and wishbone suspension. Steering was power assisted rack and pinion with vented disc brakes all around, the rear discs being positioned inboard. The interior of the car was quite luxurious and it was almost fully covered with leather.


Production of the Series 1 began in 1973. For 1980 the modernized series 2 was introduced, with slight modifications occurring later as well.

A Longchamp GTS variant was introduced at the 1980 Turin Motor Show, featuring wider wheels and flared wheel arches and minor suspension setting differences to better utilize the widerCampagnolo wheels with Pirelli P7 tyres. A Longchamp cabriolet variant ("Spyder") also appeared at the 1980 Turin Motor Show. It was made by Carrozerria Pavesi of Milan, and a small number were built to GTS specifications. Pavesi also converted a number of older coupés.

A total of 409 Longchamps were built (395 coupes and 14 spyders) between 1972 and 1989, with only a couple per year built during the last years. The vast majority are of Series 1 specifications. Some claim that production actually came to an end in 1986, with later cars being sold from stock. The Maserati Kyalami was very similar to the Longchamp, although no body panels were actually shared. The Kyalami also used a Maserati V8, rather than the Ford unit favored by De Tomaso.
