Audi A4 B9 Fuel Economy Malaysia

A4 Fuel Economy
- 2.0 TFSI: 11–14 L/100km city; 7–9 L/100km highway
- Efficiency mode via MMI — reduces A/C and throttle response
Maximising TFSI Economy in Malaysian Conditions
Malaysian A4 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 A4, 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 2.0 TFSI (B9/B9.5) / 45 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 A4.
