The 2002 Le Mans 24 Hours witnessed a historic moment as Audi clinched an unprecedented 1-2-3 victory with its factory-prepared R8 race cars. This remarkable achievement cemented Audi’s place in Le Mans history, becoming only the fifth manufacturer to win the world’s toughest endurance race three times in a row with a factory team. Furthermore, Audi became the first to achieve this hat-trick in nearly two decades. The driver trio of Frank Biela, Tom Kristensen, and Emanuele Pirro etched their names into motorsport legend by becoming the first driver lineup to win Le Mans three consecutive times.
At first glance, the 2002-spec Infineon Audi R8 appeared visually identical to its predecessor. However, according to Wolfgang Appel, Head of Vehicle Technology at Audi Sport, subtle yet significant optimizations were implemented beneath the surface. These modifications, while difficult to discern even for experts, represented a comprehensive refinement of the R8 across all performance aspects. Appel confidently stated, “The car should be faster than last year on all tracks,” highlighting the performance gains achieved through these meticulous enhancements.
Ulrich Baretzky, Head of Engine Technology, spearheaded the evolution of the R8’s formidable 3.6-liter V8 twin-turbo engine. While a completely new engine wasn’t developed for the 2002 season, the focus shifted to fine-tuning the existing FSI powerplant. Baretzky explained, “Because last year the development time leading up to Le Mans was very short we knew the FSI engine still had some potential. In the meantime, we gained a lot more experience with the FSI technology.” This continuous development and refinement of the FSI technology were crucial in maximizing the engine’s performance and reliability for the demanding Le Mans race.
The FSI, or Fuel Stratified Injection, engine technology is a key element in the 2002 Audi R8’s performance. This system directly injects a precise amount of fuel into the combustion chamber at an immense pressure of 100 bars. The benefits of FSI are multifold, including reduced fuel consumption, enhanced power output at lower engine speeds, and improved engine responsiveness. These advantages are particularly critical in endurance racing, where efficiency and performance are paramount.
The 2002 Audi R8 wasn’t just about engine innovation; it was a marvel of engineering from the ground up. Its specifications highlight the advanced technology and meticulous design that contributed to its Le Mans dominance.

The heart of the 2002 Audi R8 was its 90-degree V8 engine, force-fed by twin Garett turbochargers. This powerplant delivered an impressive 610 bhp and 700 nm of torque, translating to a remarkable specific output of 169.44 bhp per liter. The lightweight carbon fiber monocoque chassis contributed to an exceptional bhp/weight ratio of 677.78 bhp per tonne, ensuring blistering acceleration and agile handling on the track.
The chassis featured advanced double-wishbone front suspension with push-rod actuated inboard spring damper units and gas-filled shock absorbers, providing exceptional control and stability at high speeds and through demanding corners. Stopping power was provided by vented carbon fiber discs, ensuring consistent and reliable braking performance throughout the grueling 24-hour race.
The aerodynamic design of the 2002 Audi R8, while subtly refined from the previous year, played a crucial role in its performance. The car’s dimensions – 4650 mm length, 2000 mm width, and 1080 mm height – were carefully optimized for aerodynamic efficiency and stability. The car ran on bespoke tires, 33/65-18 at the front and 37/71-18 at the rear, mounted on 18-inch wheels, ensuring optimal grip and handling.
Power from the V8 engine was delivered to the wheels through a sequential 6-speed transmission, allowing for rapid and precise gear changes, essential for maintaining momentum and speed on the race track. The steering system was a rack and pinion setup with power steering, providing responsive and accurate control.
In conclusion, the 2002 Audi R8 was more than just a race car; it was a symbol of Audi’s engineering prowess and commitment to motorsport excellence. Its 2002 Le Mans victory was a testament to its refined design, powerful FSI engine technology, and the dedication of the Audi Sport team. The 2002 Audi R8 remains a celebrated icon in racing history, embodying the spirit of innovation and competitive drive.
