The R8 is powered by a 3.6 L Audi V8 with Fuel Stratified Injection (FSI), which is a variation on the concept of gasoline direct injection developed by VW; it maximizes both power and fuel economy at the same time. FSI technology can be found in products available to the public, across all brands in the Volkswagen Group.

Advantages over the previous version V8 from the EA824 family: › High torque at low rpm › Improved responsiveness › Significant increase in efficiency › Increased power output and torque › Better fuel economy › Meets the relevant country-specific emission standards › Thermal management system (new cooling module)
