Audi Q8 Fuel Economy Malaysia
Q8 3.0T 48V city: 12–15 L/100km; highway 8–11 L/100km. Cylinder deactivation (COD) at cruise: 3 cylinders off — save 10–15% highway. 48V coasting recovers braking energy. Efficiency mode: biggest gain at steady highway speed.

Q8 Fuel Economy
- 55 TFSI 3.0T: 16–22 L/100km city (heavy coupe SUV)
- 48V MHEV: energy recovery reduces city consumption by ~7–10%
- Keep carbon clean — dirty valves add 1–2 L/100km on V6
Maximising TFSI Economy in Malaysian Conditions
Malaysian Q8 owners face three fuel economy challenges: A/C load (equivalent to 1–2 L/100km extra), city stop-start traffic, and premium RON 97 costs. For your Q8, keep tyres at the correct pressure (under-inflation by 5 PSI increases consumption by 3–5%), use Efficiency mode in city traffic, and avoid prolonged idling with A/C on — the 55 TFSI / 60 TFSI V8 Quattro uses roughly 0.6–0.8 L/hour at idle with full A/C load. Highway driving at 100–110 km/h in the top gear of the S tronic delivers the best real-world economy for the Q8.
