Audi R15 TDI (LMP1)
The Audi R15 TDI is Audi’s ultra-efficient diesel-powered Le Mans prototype that succeeded the legendary R10 in the top class of endurance racing. Developed for the 2009 FIA World Endurance Championship and 24 Hours of Le Mans, it was built around low drag, outstanding fuel economy, and relentless long-run pace.

In the Simulator Feel
The R15 TDI feels like a torque-rich, aero-efficient endurance weapon that excels in consistency and momentum. It’s not the sharpest prototype by modern standards, but it rewards smoothness and patience with immense stability at speed and excellent tire-friendly behavior over long stints. Compared to screaming petrol prototypes, it has a very distinct personality — strong low-end shove, measured acceleration, and a planted, confidence-building chassis.
Engine & Sound: The twin-turbo V10 TDI delivers that unmistakable diesel prototype character: a deep, hard-edged rumble with heavy turbo spooling and a mechanical, industrial growl under load. It doesn’t rev like a high-strung gasoline race car, but the mid-range torque is relentless and makes slow corners especially satisfying on exit.
Handling Characteristics:
Cornering: Stable and predictable with a slight understeer tendency at the limit, especially on entry.
Traction: Excellent traction and strong rear-end stability, with torque delivery that’s easy to modulate once you learn the throttle.
Braking: Strong carbon braking performance, though it prefers a disciplined, straight-line approach to avoid unsettling the platform.
Top Speed: Highly competitive thanks to its low-drag philosophy and efficient power delivery.
Driving Style Tip: Drive it clean and rhythmically. The R15 TDI rewards early rotation, minimal steering scrub, and smooth throttle application so you can carry speed without overworking the tires. It shines on long, flowing circuits and high-speed endurance tracks where efficiency matters as much as raw pace.
Livery & Aesthetics: The R15 TDI has the classic Audi prototype look — low nose, massive rear bodywork, and purposeful aerodynamic detailing. The clean factory livery and sharp body lines make it instantly recognizable as one of the most iconic diesel racers ever built.
Whether you’re chasing qualifying pace or logging a full tank stint, the Audi R15 TDI delivers a uniquely Le Mans-flavored sim experience: efficient, torquey, and ruthlessly composed.
