Alphi was a French automobile manufacturer active between 1929 and 1931, during which it produced just four cars. The brand name Alphi originated from the initials of its three founding engineers: Automobiles du Luart, Poniatowski, Hougardy, and Ingėnieurs. The company was founded in Paris on rue de l'Université.
The initial pair of models shared a wheelbase measuring 2600 mm and were equipped with a 6-cylinder side-valve 1485 cc engine supplied by C.I.M.E. These vehicles, designed with racing characteristics, featured two seats positioned side-by-side. One of these competed in the 1929 24 Hours of Le Mans, driven by Sosthènes de La Rochefoucauld, but it retired after completing 45 laps and did not continue in motorsport. The second model was fitted with a supercharger for the 1929 French Grand Prix at Le Mans; however, it was not ready to race and ultimately did not take part. This car was also considered heavy relative to its power capacity.
The other two automobiles were touring versions powered by Continental engines: a 2.6-litre inline-six and a 5.0-litre inline-eight. Both touring cars incorporated independent rear suspension utilizing transverse axles, along with rigid front axles.
By the year 1968, only the supercharged racing car and the six-cylinder touring model were still extant; as of 2025, solely the race car survives following the loss of the touring vehicle to fire in 1996.
