This manual is built for the 2026 Audi RS Q8, the RS-tuned version of the Q8 rather than a generic large-SUV writeup. Audi's OEM parts catalog confirms service data for this model year; the engine and trim naming below are carried forward from the most recent confirmed model year, so treat exact trim naming and output as subject to confirmation.
Engine
- 4.0L V8 (DWNB) Turbocharged Mild Hybrid EV-Gas (MHEV)
Trims
- Base Sport Utility 4-Door
Known issues on the 2026 RS Q8. One recall is on federal record for this model year: NHTSA campaign 25V900000, covering a software error that may prevent the rearview camera image from displaying as intended, which puts the vehicle outside Federal Motor Vehicle Safety Standard 111 for rear visibility and reduces the driver's view behind it when reversing. Dealers correct it with a software update at no charge. No complaints are logged with NHTSA for this model year. Check the campaign by VIN, because a software remedy leaves no visible evidence and is easy to assume was already performed.
The turbocharged V8 driveline, RS-specific brakes and suspension, and the body and cabin sections all follow Audi's own service structure, so the torque values and step order match what a dealer technician works to.
