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 PeugeotA4V10, used by the McLaren Formula One team in 1994, initially developed 700 PS (515 kW; 690 bhp) at 14,250 rpm. It was later further developed into the A6, which produced even more power; developing 760 PS (559 kW; 750 bhp) at 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. Teams using Peugeot's V10 engine scored a total of 14 podium finishes, with 9 third places, and 5 second places, but never managed to win a race.[4]
