Mercedes-Benz GLA vs Audi Q3 Comparison 2026: Price, Mileage, Features

Comparison overview: The Mercedes-Benz GLA starts at ₹49.70 L and the Audi Q3 at ₹51.99 L, a difference of ₹2.29 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹2.54 L. Here is what the extra money actually buys.

Mileage and running cost: These two figures are not like for like. The Mercedes-Benz GLA number is for the Diesel/Petrol Automatic and the Audi Q3 number is for the Petrol Automatic, so compare the variants you are actually shortlisting.

What one gives that the other does not: The Mercedes-Benz GLA adds Driver Airbag, Passenger Airbag, Side Airbag, Curtain Airbag and Seat Belt Warning. The Audi Q3 adds Steering Column, Electric Adjustable Seats, Automatic Climate Control, Air Quality Control and Lumbar Support. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Mercedes-Benz GLA if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹2.29 L for your down payment than spend it on features.

Buy the Audi Q3 if you do regular highway runs, you carry luggage or a pram often, and you want Engine Type without waiting for the next facelift.

The one thing that settles it: Mercedes-Benz GLA offers Driver Airbag.

Before you sign anything:

Ex-showroom price is not what you pay. Add registration, road tax, insurance and handling, and expect the final figure to land ten to twelve percent higher. Road tax changes state to state, so a car that costs the same in two cities does not cost the same to own.

Ask the dealer four things before you book. What is the current waiting period for the variant you want. What is the on-road figure.

Then drive both cars back to back on the same day, on a road you actually use. Take your family. Put your usual luggage in the boot. Most people decide in the first ten minutes, and it is rarely for the reason they expected.
