Profile, The Legendary History of French Auto Racing Maker Welter Racing

Welter Racing is a French sports car maker that has long made its mark on the endurance circuit, famously competing in the prestigious 24 Hours of Le Mans since 1990 under the direction of Gérard Welter, Peugeot's late head of design, alongside his wife Rachel Welter.

Gérard Welter built a legacy deeply rooted in endurance racing milestones, highlighted by a stunning C3 class victory at Le Mans in 1993 with a Peugeot 1.9 L turbocharged I4 powerplant entry driven by Patrick Gonin, Alain Lamouille, and Bernard Santal.

The legendary team's storied career at La Sarthe also boasts four second-place finishes, one third-place run, and a sensational front row start in 1995 that ultimately triggered a major regulatory rule change for the following racing season.

Beyond class victories, the constructor etched its name into motorsport history in 1988 under the ambitious Project 400, aiming to build the very first car to break the 400 km/h barrier during the grueling 24 Hours of Le Mans endurance classic.

Breaking the 400 kmh Speed Barrier at Le Mans

During the 1988 endurance event, Welter's low-drag configuration WM Peugeot P88 achieved a staggering top speed of 405 km/h on the iconic Mulsanne Straight, driven by veteran racing driver Roger Dorchy.

The historic speed run was accomplished through innovative engineering choices, including moving the radiators and intercoolers alongside novel aerodynamic ducting configured specifically to maximize straight-line velocity.

Despite dominating headlines with their blistering speed, persistent reliability hurdles throughout the weekend involving the turbocharger, cooling systems, and electrical components ultimately forced the team to retire from the race.

The legendary speed record was permanently safeguarded in subsequent years with the addition of chicanes built directly into the Mulsanne Straight in 1990, ensuring cars could no longer reach such extreme speeds on shortened straights.
