Peugeot V10 3.5 l 715 hp engine – more powerful and stable than V8, with more torque than V12

In the 1990s, Peugeot competed with Jaguar, Mercedes, Mazda and Toyota in the World Endurance Championship with a standard 3.5 liter V10 engine.

The 3.5 liter Peugeot engine represents a short period in the history of world endurance racing. In the late 1980s, FISA (Fédération Internationale du Sport Automobile) tried to unify at a technical level its two major league championships (Formula 1 and Endurance). To this end, it was decided in 1991 that both championships would require the use of naturally aspirated engines with a capacity of 3.5 liters.

Peugeot chose the V10 engine, more powerful and stable than the V8, which produced more torque than the V12, an important factor in endurance racing. It also got improved acceleration, which resulted in improved dynamics. According to Peugeot engineers, the V10 also offered the best balance between weight and fuel economy.

Other designers were less enthusiastic. The development of mechanics was difficult and required a large financial commitment. In 1991, Jaguar and Mercedes followed in Peugeot’s footsteps, but ended their participation in the championship at the end of the season. Only Mazda retained its share the following year when another Japanese manufacturer, Toyota, returned to international endurance racing.

The battle between Peugeot and Toyota rocked the 1992 season, promising to be the last of its kind. Their rivalry culminated in the 1993 Le Mans 24 Hours, marking the end of 3.5 liter naturally aspirated engines in non-Formula 1 competition. There could only be one winner.

The 1993 race was won by Peugeot Talbot Sport, with drivers Geoff Brabham and Le Mans pioneers Éric Hélary and Christophe Bouchut completing 375 laps in their Peugeot 905 Evo 1B. Peugeots took the first three places, Toyota took only the fourth place and the next due to many car problems, Japanese cars were destroyed, among others. power plants and gearboxes.

The V10 engine in the Peugeot 905 EVO 1B produced 715 hp.
