Mercedes-Benz GLS Mileage
₹132.07 Lakh to ₹143.00 Lakhex-showroom
Both GLS engines carry the same ARAI rating of 12 kmpl, which is modest but expected for a heavy inline-six seven-seater. The petrol 450 and diesel 450d read the same on paper, though the diesel usually feels more frugal on long highway runs. Treat 12 kmpl as a lab figure, since city driving and the car's weight will pull real returns lower.

Mileage is how far the GLS travels on one litre of fuel (or one kg of CNG). A bigger number means you spend less on fuel. Carmakers quote an ARAI lab figure; in real driving you get a bit less, so both are shown below.

Mercedes-Benz GLS mileage: common questions
What mileage does the GLS return?
Both the petrol 450 and diesel 450d are rated at 12 kmpl on the ARAI test. Real-world figures will sit under this given the car's size and weight.
Do the petrol and diesel GLS differ on economy?
On the rated figure both read 12 kmpl. In practice the diesel 450d tends to feel more efficient on long trips thanks to its torque.
Why is the GLS mileage on the low side?
It is a large, heavy seven-seat SUV with a 3.0 litre inline-six and all-wheel drive. Moving that mass simply uses more fuel.
