World’s most famous TDI for sale (again)

Next week marks the first round in a very different Formula 1 World Championship. The series has undergone one of the biggest technical changes in history, with revamped aerodynamic regulations bringing smaller cars with active wings, while a new engine configuration sees a near 50/50 power split between combustion and electric power. On top of that, you’ve got two brand new manufacturers to the sport, with Cadillac starting from scratch while F1 stalwarts Sauber has been taken over by Audi.

While Cadillac’s entry was relatively swift and well publicised, Audi and the wider Volkswagen Group’s route into F1 has been far longer in the making. VW has long toyed with the idea of bringing one of its brands into F1, with Porsche providing engines to McLaren in the mid-’80s and even developing a V10 that’d ultimately wind up in the back of the Carrera GT. Audi, meanwhile, was often rumoured to be in talks to join the grid solely on its performance in sports car racing. Between 2000 and its final season in 2016, it racked up a staggering 13 victories at Le Mans, one of which came in spectacular fashion in an R18 TDI much like the car we have for sale here.

At the 2011 running of the 24 Hours of Le Mans, Audi brought three of its radical new R18 prototypes, moving away from the old car’s open top design for a closed canopy and exchanging its predecessor’s 5.5-litre V10 diesel for a lighter 3.7-litre V6 turbo. It was quick from the get-go, with Audi running 1-2-3 in the early hours of the race. Soon after, the number 3 car driven by Allan McNish was involved in a horrifying accident at the Dunlop Esses that, incredibly, he and a handful of marshals and photographers walked away from. Then, in the middle of the night, Mike Rockenfeller clattered into a GT at full speed near Indianapolis, obliterating all but the R18 survival cell. Luckily, he too walked away. Despite its misfortune, Audi kept its number 2 car ahead of a trio of Peugeot 908s to claim a sensational tenth victory around la Sarthe.

What we have here is an R18 TDI built to the same spec as the Le Mans winner, albeit with a slightly different competition history. Chassis 107 competed in the Intercontinental Le Mans Cup, now known as the World Endurance Championship, throughout the 2011 season with mixed results (a 4th place here, 7th there). However, a year later, it’d score pole position at the inaugural WEC round at Sebring, Audi’s tenth at the venue. It would ultimately end the 12-hour race 15 laps down, continuing its streak of misfortune, with Audi placing it into retirement straight after.

From there it was subsequently re-liveried in the 2011 Le Mans-winning colours and served as a promotional car, before being gifted to Audi legend André Lotterer. In 2024, it reappeared at the Goodwood Festival of Speed with 2011 Le Mans winner Benoît Tréluyer behind the wheel, and has since been reverted back to its Sebring colours to reflect its spectacular lap around the old air base.

Audi would later adapt the R18 platform with a trick all-wheel drive hybrid system, which proved so innovative that F1 teams demanded a change in the 2026 regulations to prevent front-axle energy harvesting. While that tech never made it on to chassis 107 here, it still played a vital role in Audi’s domination of the sport. Naturally, you’ll need to give the seller a call to find out about pricing, but a relatively modern prototype that’s eligible for historic events like Le Mans Classic will surely command seven figures. That’s a lot of money to spend on a old diesel, yet we can’t help but think it’ll be worth it.
