Additional Notes

  • The Audi R8 Coupé 4.2 FSI quattro (309 kW) and 5.2 FSI quattro (386 kW) variants equipped with the r tronic semi-automatic transaxle share a base fluid capacity of 3.5 liters, rising to 4 liters when the transmission oil cooler is present. The cooler adds a small but fixed volume to the circuit that must be accounted for during a service fill.
  • The 4-liter figure for r tronic-equipped variants applies only when a transmission oil cooler is installed. Without the cooler, the correct service fill remains 3.5 liters across all r tronic configurations in the 2007-2015 range.
  • Variants fitted with the s tronic semi-automatic transaxle carry a substantially higher fluid capacity of 8 to 10.5 liters. The range reflects variation depending on the specific fill condition or drain method, as dual-clutch transmissions of this type typically retain fluid in multiple internal circuits that may not fully drain during a standard service.
  • The R8 LMX (2014-2015) is specified with a fixed s tronic capacity of 10.5 liters, rather than the 8-10.5 liter range listed for other s tronic variants. A fixed upper-bound figure of this kind generally corresponds to a complete fill following a full fluid evacuation or overhaul procedure.
  • The 316 kW version of the R8 4.2 FSI quattro transitioned from the r tronic to the s tronic between its two production sub-periods. The 2010-2012 build uses the r tronic with a 3.5 or 4-liter capacity, while the 2012-2015 build uses the s tronic with an 8-10.5 liter capacity, representing a significant difference in fluid volume for the same engine displacement.
  • The R8 GT (2010-2012) uses the r tronic transaxle and shares the same 3.5-liter base capacity and 4-liter cooler-equipped capacity as the standard 4.2 FSI and 5.2 FSI r tronic variants from the same era.
  • All specifications across the 2007-2015 range are listed under normal use conditions, meaning no separate severe-use interval or capacity adjustment is specified for any of the configurations covered.
  • The shift from r tronic to s tronic across multiple R8 variants from 2012 onward corresponds to a more than doubling of the listed transmission fluid capacity, reflecting the fundamentally different internal architecture of a dual-clutch unit compared to the single-clutch automated manual design of the r tronic.
