From the mid-2000s until 2020, LMP1 was the premier class at Le Mans. Manufacturers had almost complete freedom when it came to technology and battled for every tenth of a second with diesel prototypes and, later, hybrid racing cars. Audi, Peugeot, Porsche and Toyota poured enormous budgets into their cars. The result was over 1,000 PS and lap times that no one has beaten to this day. The images in this collection show racing cars such as the Audi R18, the Porsche 919 Hybrid and the Toyota TS050, which defined an era of technical arms race.
