Maximising TFSI Economy in Malaysian Conditions
Malaysian A5 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 A5, 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) / 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 A5.
