The Peugeot V10 engine is a series of naturally-aspirated, V10, racing engines; produced between 1990 and 2000. These engines were used to compete in the World Sportscar Championship, between 1990 and 1993, with Peugeot winning the 24 Hours of Le Mans two years in a row (1992 and 1993). In 1994, they decided to make the switch to Formula One, using the same 3.5 L V10 derived from their highly successful, Le Mans-winning 905 Group C sports prototype, that was easily adjusted to F1 regulations. Peugeot debuted as an engine supplier with the McLaren team and remained in F1 until the end of the 2000 season.[1][2]

Peugeot 905 SA35-A1/SA35-A2 engine

Technically advanced, the 905 used a light alloy and high revving SA35-A1 3499 cc naturally aspirated V10 engine that was similar to F1 engines of the time. The 905 was built at Vélizy-Villacoublay [3]

The more powerful SA35-A2 engine evolution, used in the 905B, made its race debut at the Nürburgring round of the 1991 series.

Peugeot decided to switch to Formula One, using the same 3.5L V10 from the 905 that was easily adjusted to F1 regulations. In 1994, Peugeot debuted as an engine supplier with the McLaren team. The Peugeot A4 V10, used by the McLaren Formula One team in 1994, initially developed 700 bhp (522 kW; 710 PS) @ 14,250 rpm. It was later further developed into the A6, which produced even more power; developing 760 bhp (567 kW; 771 PS) @ 14,500 rpm. Peugeot remained in F1 until the end of the 2000 season, when, after little success, they decided to focus and concentrate their efforts on the World Rally Championship.
