Questions people ask
What is the real mileage of the Mercedes-Benz GLS?
On owner reports the Mercedes-Benz GLS Petrol Torque Converter is the most efficient at 11.00 kmpl. In ordinary driving we estimate about 9.3 kmpl in the city and 12.2 on the highway, with one or two people on board.
Which Mercedes-Benz GLS variant gives the best mileage?
Every Mercedes-Benz GLS variant uses the same engine, so they all return the same figure.
How much mileage does the Mercedes-Benz GLS give in city traffic?
We estimate around 9.3 kmpl at best, on the Petrol Torque Converter. City driving costs roughly a quarter of the rated figure because of signals, idling and the air conditioning.
Does E20 petrol reduce Mercedes-Benz GLS 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 Mercedes-Benz GLS 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.
