![]() Like the Acura ARX-02a, Audi has chosen to install taller and wider tyres at the front for increased contact patch. ![]() The R18 has an engine cooling duct above the cockpit roof as well as redesigned rear wheel arches to channel more air to the rear wing. Unlike other coupé competitors in its class, the chassis on the R18 is not composed of two halves but rather is of single-piece construction for improved rigidity. This is called a 'hot valley' configuration and is opposed to the traditional configuration with each cylinder bank of a V engine exhausting outwards to their respective turbochargers. The R18's V6 engine exhausts inwards between the cylinder banks, where the turbocharger is placed. The new engine has a single Garrett ( Honeywell Turbo Technologies) TR30R VGT turbocharger, as opposed to the twin TR30R configuration of both the Peugeot 908 HDi FAP and the previous Audi R15 TDI. This is less than the outgoing R15, but the V6 engine's fuel consumption will more than likely be lower than that of the outgoing V10 engine on the R15. Despite the capacity reduction, the 3.7L V6 is claimed to develop more than 397 kilowatts (532 bhp) of power. The new gearbox is electrically controlled instead of pneumatically controlled, saving weight by eliminating the pneumatic system. There were five further evolutions of R18 until Audi quit the FIA World Endurance Championship in 2016.Īudi R18 TDI Ultra at the 1000km of Spa 2011, its debut raceĪs the new rules for Le Mans in 2011 the car features a stabilisation fin on the engine cover and has a new six-speed gearbox. The R18 is also the first racing car from Audi to feature hybrid power.Īlthough Audi have previously given each new developed model of endurance racing car a distinct model number, the head of Audi Sport, Wolfgang Ullrich, suggested the R18 designation for Audi endurance racing cars could be used for the foreseeable future as a result of rival car manufacturer Renault already holding trademarks for car model names R19 through to R35. ![]() For the first time since the 1999 R8C, the Audi Le Mans prototype used a closed cockpit design. Like its predecessor, the R18 uses a TDI turbocharged diesel engine but with a reduced capacity of 3.7 litres and in a V6 configuration. The Audi R18 is a Le Mans Prototype (LMP) racing car constructed by the German car manufacturer Audi AG.
