Dallara’s return to prototype racing for the first time since the original Audi R18 TDI, the P217 made its debut in 2017. The car competes in the LMP2 class in both the FIA World Endurance Championship and European Le Mans Series, while a Daytona Prototype International-spec version of the car races at the top level of the IMSA WeatherTech SportsCar Championship with Cadillac branding as part of a relationship with General Motors.
The LMP2 P217 is powered by a 4.2-liter Gibson V8, and features a six-speed sequential paddle shift transmission by Xtrac. Drivers who raced in the car in its 24 Hours of Le Mans debut included Formula 1 legend Rubens Barrichello, former Le Mans winner Jan Lammers, and IndyCar veteran Mikhail Aleshin. Other Formula 1 veterans who have driven the car at Le Mans include Felipe Nasr, Sergey Sirotkin, and Giedo van der Garde.
