Additional Notes
- Across all Audi R8 Coupé configurations listed for 2007-2015, the front differential carries a dry fill capacity of 1.5 liters and a service fill capacity of 1.4 liters.
- The 0.1-liter difference between dry fill and service fill reflects residual fluid that remains in the differential housing during a routine drain, meaning a full overhaul or assembly from a dry state requires the larger 1.5-liter volume.
- All listed configurations specify normal use conditions, which generally refers to standard on-road driving as opposed to track, towing, or other high-stress operating environments.
- The 4.2 FSI quattro engine appeared in two distinct power outputs across the 2007-2015 span: 309 kW for the 2007-2010 period and 316 kW from 2010 onward, yet both share identical front differential capacities.
- The 5.2 FSI quattro at 386 kW entered the lineup in 2009, while the higher-output 5.2 FSI plus quattro at 404 kW appeared from 2012, and both variants carry the same 1.5-liter dry and 1.4-liter service fill figures as the 4.2 FSI models.
- The R8 GT, produced during 2010-2012, and the limited R8 LMX, produced during 2014-2015, share the same front differential capacity specifications as the broader R8 Coupé range despite their distinct performance positioning.
- The consistency of the 1.5-liter dry fill figure across every listed variant, spanning four-wheel-drive configurations from 309 kW to 404 kW, indicates a common front differential unit was used throughout the first-generation R8 Coupé lineup.
