The engine capacity of the Audi Q8 varies by variant, ranging from about 2,967 cc in the diesel to about 3,996 cc in the high‑performance RS Q8, with most mainstream petrol models using around 2,995 cc.
Variants and engine capacities
The Q8 lineup includes petrol, diesel, plug‑in hybrid and performance versions. Displacement figures refer to the engine’s volume in cubic centimeters (cc) and are separate from turbocharging or electric propulsion, which affect power and efficiency but not the stated displacement.
- Q8 55 TFSI quattro (3.0‑liter petrol) – 2,995 cc
- Q8 50 TDI quattro (3.0‑liter diesel) – 2,967 cc
- Q8 55 TFSI e quattro (plug‑in hybrid) – 2,995 cc petrol engine plus electric motor (displacement of the petrol block remains 2,995 cc)
- RS Q8 (4.0‑liter V8 TFSI) – 3,996 cc
- Q8 e-tron (fully electric) – no internal combustion engine displacement
Note: availability varies by market and model year. The numbers above reflect common specifications used across major markets as of 2024–2026.
Notes on interpretation
Engine displacement is one lens on a vehicle’s performance. Turbocharging, hybrid systems and electric propulsion can yield more or less power than displacement alone would imply. For example, the RS Q8’s 3,996 cc V8 is paired with twin turbochargers and advanced tuning to deliver substantially higher output than the standard 2,995 cc petrol Q8s.
How to verify for your market
Because Audi markets the Q8 with different engines and trims worldwide, the exact displacement for a given car can be confirmed on the official specification sheet from Audi or at a dealership, typically under the vehicle’s technical data.
In practice, most buyers in many regions encounter the 2,995 cc petrol option or the 2,967 cc diesel as the baseline choices, with the RS Q8 offering the separately displaced 3,996 cc V8 for performance-focused builds, and the plug‑in hybrid sharing the same 2,995 cc block with additional electric propulsion.
Summary
The Audi Q8’s engine capacity ranges from 2,967 cc (diesel) to 3,996 cc (RS Q8’s V8), with the common petrol 3.0‑liter engines at around 2,995 cc. Plug‑in hybrids use the same 2,995 cc petrol block plus electric propulsion, while fully electric Q8 e‑tron variants have no engine displacement to report. Always check your local spec sheet for the exact figures on your market and model year.
