Questions people ask
What is the real mileage of the BMW X3?
On the ARAI rating the BMW X3 Petrol 8-Speed Automatic is the most efficient at 14.61 kmpl. In ordinary driving we estimate about 10.1 kmpl in the city and 13.3 on the highway, with one or two people on board.
Which BMW X3 variant gives the best mileage?
Every BMW X3 variant uses the same engine, so they all return the same figure.
How much mileage does the BMW X3 give in city traffic?
We estimate around 10.1 kmpl at best, on the Petrol 8-Speed Automatic. City driving costs roughly a quarter of the rated figure because of signals, idling and the air conditioning.
Does E20 petrol reduce BMW X3 mileage?
Yes, a little. Ethanol carries less energy per litre than petrol, and ARAI's laboratory tests put the drop with E20 at 2% to 6%. E20 is what pumps in India have been required to sell since 1 April 2026, so the estimates on this page assume it. Switch the blend above to see the difference.
Why is the BMW X3 mileage lower here than the company figure?
Because the company figure comes off a lab cycle. This page scales it to real driving: city, mixed and highway, with an option for a full car and the AC on. The rating is still shown next to it so you can see the gap.
