The Longchamp was derived from the De Tomaso Deauville four-door saloon, using a shorter wheelbase chassis with the same suspension, engine and transmission.
The same platform underpinned the Maserati Kyalami grand tourer and the Maserati Quattroporte III saloon as Maserati was owned by De Tomaso at the time.
The Deauville and the Longchamp were the only front engine production cars produced by De Tomaso.
The Longchamp was first exhibited at the 1972 Turin Motor Show and was initially offered only as a 2-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 headlights and front indicators are from the Ford Consul/Granada.
The name Longchamp is likely a reference to the Longchamp Racecourse in Paris and/or Longchamps, Buenos Aires, a city near de Tomaso company founder Alejandro de Tomaso's birthplace.

The Longchamp featured a long and wide hood to accommodate the American power train, i.e. the 351 cubic inch (5,769 cc) Ford Cleveland V8.
The 351 Cleveland, a popular and very potent engine in early 1970s Ford muscle cars, was the same unit used in the Pantera.
It was rated at a power output of 335 PS (246 kW; 330 hp) and gave the Longchamp an official top speed of 240 km/h (149 mph).
After Ford stopped manufacturing the 351 Cleveland V8 in the US, De Tomaso sourced the engines from Ford Australia.
The standard gearbox was a three-speed Ford C-6 Cruise-o-Matic automatic transmission, however around 17 cars were equipped with a five-speed ZF manual transmission.
The suspension was independent front and rear wishbone unit equipped with coil springs.
Steering was power assisted rack and pinion and the car came with vented disc brakes all around with the rear brake discs being positioned inboard.
The interior of the car was quite luxurious and it was almost fully upholstered in leather, although the use of Ford sourced parts (steering wheel, gear shift) took away somewhat of the luxurious impression.
