Why is the real‑world fuel efficiency of the United Alpha much lower than the claimed figure?

Many drivers report only 10–12 km/L in city driving, despite manufacturer o r source estimates of higher mileage. What engine‑oriented reasons e.g., inefficient tuning, fuel‑injection mapping, under‑optimized ECU could be contributing? How much do driving conditions, traffic, and maintenance like dirty filters o r poor spark plug performance play a role?

Owners widely report lower mileage in city driving — around 10–12 km/L.

Some of this discrepancy likely comes from engine tuning: the 1.0 L MPi engine may not be very efficient under frequent stop‑start traffic, because of how fuel is injected and how the ECU is calibrated.

Local driving conditions contribute significantly: congested city traffic, frequent acceleration/braking, and sub‑optimal driving speeds all hurt fuel economy.

Maintenance issues also matter: things like clogged air filters, poorly adjusted tire pressure, o r spark plug wear could further reduce mileage.

On highways, some owners report better fuel efficiency e.g., ~15–16 km/L, which matches more closely with manufacturer-style o r ideal driving conditions.

Conclusion: The lower real-world fuel efficiency seems to be a combination of inherent engine/fuel‑system limitations plus typical Pakistani city driving conditions and maintenance factors.
