Which team holds the Le Mans record for most overall wins, with 15?

Joest Racing holds the Le Mans record for most overall wins by a team, with 15 victories. The German outfit achieved those wins across Porsche and Audi programs between 1984 and 2014.

Joest's first victories came with Porsche 956s in 1984 and 1985. After returning to the front with Porsche's TWR-built WSC-95 in 1996 and 1997, Joest became Audi's key endurance partner. Its Audi victories included the R8, R10 TDI, R15 TDI and R18-era cars.

The 15-win figure refers to a racing team or entrant record, not to one car model or one manufacturer. Porsche has more overall victories as a marque, while Audi's Le Mans success was closely connected to Joest's operational expertise. This distinction explains why answers such as Porsche or Toyota can sound plausible but do not match the wording about a team.

Joest's final listed overall wins came in Audi's dominant 2010–2014 period. The organization was later absorbed into Porsche's factory motorsport structure, but its historical Le Mans record remains separately recognized.
