Duqueine D09

The Duqueine D09 is a third-generation LMP3 prototype developed by Duqueine Engineering for the 2025 ACO LMP3 regulations. It debuted at the 2025 4 Hours of Barcelona in the European Le Mans Series, replacing the earlier Duqueine D08. The car features a carbonfibre monocoque chassis and is powered by a 3.5-litre twin-turbocharged Toyota V35A‑FTS V6 engine producing around 470 bhp, paired with a six-speed sequential gearbox and advanced aerodynamic package. Minimum weight is approximately 1000 kg, with Michelin tyres and 18-inch wheels used across the category.

During the 2025 ELMS season the D09 was entered by WTM by Rinaldi Racing, competing against rivals such as CLX Motorsport and Inter Europol Competition. While CLX Motorsport dominated the LMP3 championship, the Duqueine entry achieved competitive midfield finishes and contributed to the debut season of the new-generation LMP3 chassis.
