Suzuki Alto VXL 2024 AC Using Too Much Fuel

[furqanhamid112211]

I know running the AC does affect fuel economy, but in my case it seems excessive. I am driving a Suzuki Alto VXL 2024, and every time I switch on the AC, even for short trips in the city, the fuel average drops drastically. Without AC, it gives decent mileage.

Is anyone else facing this with the new Alto, or could this be a fault in the AC system or compressor? Would really appreciate advice or recommendations on what to get checked.

Should I go for portable ac integration? I know that can have its own pros and cons.

Kindly drop your suggestions to help me out.

Jot this down in figures, along with your commute details

Thanks for responding
I am adding bit detail of my vehicle condition:

Car: Suzuki Alto VXL 2024

Reading: ~3,500 km

Fuel Type: Regular petrol

Commute Type: Mostly city driving (Lahore), average speed 25–35 km/h

Trip Length: 8–12 km per trip, mild traffic

AC Usage: Always ON during the trip (since it’s too hot)

With AC: Fuel average drops to around 11–12 km/l

Without AC: I get around 17–18 km/l

This seems like a pretty big difference for a small car. I'm concerned whether this is normal for this model or if there could be an issue with the AC system or tuning.

Doing a lot of start and stop driving specially with a heavy foot will return this kind of mileage.

You are running short trips, probably in the streets or congested roads that is why this mileage

Drive 50 or so kms on ring road with mileage calculation via brim to brim method and then report results.

For reference a Suzuki Alto at 80 to 90 kmph (max safe speed for this car) returns 22 to 23 kmpl with AC and 2 passengers with oem recommended tire size and inflated as per specs.

This indicates that yoi have a heavy foot.
With a heavy foot, small engines provide bad economy
