Instant response, lightning-fast high-revving and a unique sound – the heart of the Audi R8 is its V10 naturally aspirated engine. It is available to customers in two output ratings. The almost identical drive technology of the V10 engine in the R8 LMS GT3 and R8 LMS GT4 is put to good use on the racetrack. The V10, which is produced at the engine plant in Győr, Hungary, is very compact. A separate radiator controls the temperature of the engine oil, which comes from a dry sump. This principle was adopted from motor racing and allows for an extremely low installation position of the engine, producing a low center of gravity. The pump module operates with multiple suction stages and assures proper lubrication under all conditions – including during lateral acceleration of around 1.5 G, which is possible in the R8. Both engines have a gasoline particulate filter.
