In an answer to the 2009 issues, Audi reworked the R15 for 2010 (under the R15 TDI plus designation) with a higher reliability factor; unexpected Peugeot reliability issues of the 908 HDi FAP forced all four cars (including one by Oreca) to retire before the end of the race and resulted in a clean sweep of the podium in the 2010 24 Hours of Le Mans, with all three cars running farther than the former race record, despite that the R15s were not using the V10 TDI engines at full and were not running faster than the four 908s.
