Additional Notes
- Both the RS Q8 TFSI quattro (441 kW) and the SQ8 TFSI quattro (373 kW), each introduced in 2020, share the same coolant fill specification: the cooling system is to be filled to a level between the minimum and maximum marks.
- A "between min and max" specification refers to the acceptable operating range on the coolant reservoir, rather than a fixed volume figure. No discrete liter capacity is listed for either configuration.
- The RS Q8 TFSI quattro carries a 441 kW output rating, while the SQ8 TFSI quattro is rated at 373 kW. Despite the difference in power output, both share an identical coolant level specification under normal use conditions.
- The normal use condition applies to both the RS Q8 TFSI quattro and the SQ8 TFSI quattro coolant specifications, meaning no separate severe-use or first-change interval is listed for either variant.
