Audi A8 Fuel Economy Malaysia
A8 D4 3.0T city: 13–17 L/100km; highway 9–12 L/100km. D4 4.0T biturbo city: 17–22 L/100km. D5 3.0T 48V city: 11–14 L/100km; highway 8–10 L/100km. COD cylinder deactivation V6 D5: 3 cylinders off at cruise — 10–15% highway saving. 48V coasting: BSG recovers energy under deceleration.

A8 Fuel Economy
- 55 TFSI 3.0T: 15–20 L/100km city (long wheelbase, heavy car)
- 48V MHEV: energy recovery reduces fuel consumption by ~7–10% vs non-hybrid competitor
- A8 is a fuel-hungry flagship — realistic city economy 16–18 L/100km
Maximising TFSI Economy in Malaysian Conditions
Malaysian A8 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 A8, 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 3.0 TFSI V6 / 60 TFSI V8 / 4.0 TFSI 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 A8.
