Audi began racing prototype sportscars in 1999, debuting at the Le Mans 24 hour. Two car concepts were developed and raced in their first season - the [[Audi R8R]] (open-cockpit 'roadster' prototype) and the [[Audi R8C]] (closed-cockpit 'coupé' GT-prototype). The R8R scored a credible podium on its racing debut at Le Mans and was the concept which Audi continued to develop into the 2000 season due to favourable rules for open-cockpit prototypes.

However, most of the competitors (such as BMW, Toyota, Mercedes and Nissan) retired at the end of 1999.
The factory-supported [[Joest Racing]] team won at Le Mans three times in a row with the Audi R8 (2000–2002), as well as winning every race in the [[American Le Mans Series]] in its first year. Audi also sold the car to customer teams such as [[Champion Racing]].

In 2003, two [[Bentley Speed 8]]s, with engines designed by Audi, and driven by Joest drivers ''loaned'' to the fellow [[Volkswagen Group]] company, competed in the GTP class, and finished the race in the top two positions, while the Champion Racing R8 finished third overall, and first in the LMP900 class. Audi returned to the winner's podium at the 2004 race, with the top three finishers all driving R8s: Audi Sport Japan Team Goh finished first, Audi Sport UK Veloqx second, and Champion Racing third.

At the [[2005 24 Hours of Le Mans]], Champion Racing entered two R8s, along with an R8 from the Audi PlayStation Team [[Oreca]]. The R8s (which were built to old LMP900 regulations) received a narrower air inlet restrictor, reducing power, and an additional {{convert|50|kg|0|abbr=on}} of weight compared to the newer LMP1 chassis. On average, the R8s were about 2–3&nbsp;seconds off pace compared to the [[Pescarolo Sport|Pescarolo]]–[[Judd (engine)|Judd]]. But with a team of excellent drivers and experience, both Champion R8s were able to take first and third, while the Oreca team took fourth. The Champion team was also the first American team to win Le Mans since the Gulf Ford GTs in 1967. This also ends the long era of the R8; however, its replacement for 2006, called the [[Audi R10 TDI]], was unveiled on 13 December 2005.

The R10 [[Turbocharged Direct Injection|TDI]] employed many new and innovative features, the most notable being the [[twin-turbo]]charged [[Direct fuel injection|direct injection]] [[diesel engine]]. It was first raced in the [[2006 12 Hours of Sebring]] as a race-test in preparation for the [[2006 24 Hours of Le Mans]], which it later went on to win. Audi had a win in the first diesel sports car at 12 Hours of Sebring (the car was developed with a Diesel engine due to ACO regulations that favor diesel engines). As well as winning the [[24 Hours of Le Mans]] in 2006, the R10 TDI beat the [[Peugeot 908 HDi FAP]] in {{24hLM|2007}}, and in {{24hLM|2008}}, (however Peugeot won the 24h in 2009) with a podium clean-sweep (all four 908 entries retired) while breaking a distance record (set by the [[Porsche 917]]K of [[Martini Racing]] in {{24hLM|1971}}), in {{24hLM|2010}} with the [[Audi R15 TDI|R15 TDI Plus]].<ref>{{cite web | url = http://www.joest-racing.de/web/news/news.php?id=541&sprache=e | archive-url = https://web.archive.org/web/20110719050259/http://www.joest-racing.de/web/news/news.php?id=541&sprache=e | archive-date = 19 July 2011 | title = Audi achieves record victory at Le Mans with new technology  | work=joest-racing.de; [[Audi Sport]] | publisher=Joest Racing | date = 13 June 2010 | access-date =16 June 2010}}</ref>

Audi's sports car racing success would continue with the [[Audi R18]]'s victory at the [[2011 24 Hours of Le Mans]]. [[Audi Sport Team Joest]]'s [[Benoît Tréluyer]] earned Audi their first [[pole position]] in five years while the team's sister car locked out the front row.<ref name=AFP_Audi_Front_Row>{{cite news|url=https://www.google.com/hostednews/afp/article/ALeqM5ikxFTgOVDE0DXKGgxuzUurSVk4dw?docId=CNG.4facb82ec8689e5a037eb4e7286eff0b.3b1|archive-url=https://web.archive.org/web/20120525111136/http://www.google.com/hostednews/afp/article/ALeqM5ikxFTgOVDE0DXKGgxuzUurSVk4dw?docId=CNG.4facb82ec8689e5a037eb4e7286eff0b.3b1|url-status=dead|archive-date=25 May 2012|title=Audi back on front row for Le Mans 24 Hours|agency=Agence France-Presse|date=10 June 2011}}</ref> Early accidents eliminated two of Audi's three entries, but the sole remaining [[Audi R18 TDI]] of Tréluyer, [[Marcel Fässler (racing driver)|Marcel Fässler]], and [[André Lotterer]] held off the trio of [[Peugeot 908]]s to claim victory by a margin of 13.8 seconds.
