Fuel Efficiency with AC and Full Load

Using air conditioning — especially in hot Pakistani summers — and carrying full passenger load often seems to drastically reduce the car’s mileage. To what extent do AC usage and extra weight affect fuel efficiency in normal daily use, and how much in kilometers per liter can owners expect under those conditions?

Owner reviews often note that when AC is used intensively hot weather, o r when the car carries more passengers o r luggage, fuel consumption worsens. For example, one review said the car gives “up to 19 km/L” but s to “around 14 km/L with air conditioning on.”

Another user complaint: some say that on some days they get ~18 km/L, but on others with AC/weight/traffic it goes down drastically to ~7–8 km/L.

Mechanically, extra load and AC put more stress on engine — requiring more fuel for same acceleration and to run compressor also, frequent stops and idling make AC usage less efficient.

Conclusion: AC usage and full load passengers/luggage noticeably reduce fuel efficiency — you may see a of several km/L compared to “ideal” mileage. Expect lower efficiency during hot, heavy‑load, city‑traffic conditions.
