The Renault Etoile Filante, fastest car in the world

L'Etoile Filante, a record machine
The achievement of the Renault Étoile Filante has yet to be bested, with a peak of 306.9 km/h over a kilometer and 308.85 km/h over 5 kilometers. Yet the sleek blue racer, measuring over five meters long, is celebrating its 60th birthday this year!
The aeronautic sector expanded rapidly after the Second World War. Joseph Szydlowski, head of Turboméca, the renowned turbine engine manufacturer, started the small-scale production of powerful turbine engines, fitted notably on the famous Alouette helicopters. He soon joined forces with La Régie Renault, which was looking for new techniques for its engines. Renault chief Pierre Lefaucheux had also set his sights on beating the world land speed record.
The project got off the ground in 1954, led by three experienced professionals: Fernand Picard, head of research; Albert Lory, the illustrious engine developer; and Jean Hébert, engineer and driver. The trio designed an outstanding vehicle powered by an ultra-powerful turbine engine developing 270 hp at 28,000 rpm. The Étoile Filante featured a tubular, polyester-clad body and two large aircraft-like fins. It was equipped with the Transfluide transmission that would later be used on the Frégates. In a nod to the aeronautics sector, it ran on kerosene and was practically vibration-free thanks to the rotation speed of the turbines.
The Etoile Filante was presented to the press and specialists on June 22, 1956 at the Montlhéry circuit. Just 2 units of the vehicle were ever produced!
Out to conquer the USA
The record set by the Étoile Filante in Bonneville in 1956 was covered in the press around the world, and in particular by US journalists. The feat helped to boost Renault’s reputation in the USA, and would indirectly favor the Dauphine, launched for export at the same time.
