Description
ALD 03 Sport Prototype C2 (Automobiles Louis Descartes)
In the mid-1980s, the racing driver and constructor Louis Descartes decided to build cars that would compete in the World Sportscar Championship from 1985 to 1991. Originally conceived with an Audi turbo 4‑cylinder engine, Descartes, due to the lack of performance, opted to install the BMW 6‑cylinder engine from the M1.
This is the most successful ALD, completely overhauled in 1990 by Louis Descartes before offering it at auction to the previous owner, who sold it in 2012 to its current owner. Thanks to its simple and economical construction, the ALD allows participation in prestigious Group C endurance races on a far lower budget than other entrants. With an 11th place overall at Le Mans 1987, it demonstrated its performance.
The engine has just been rebuilt, and the wiring harnesses, fire extinguishers and fuel tanks also meet the latest standards.
