Audi A4 vs Audi Q3 Comparison 2026: Price, Mileage, Features

Comparison overview: The Audi A4 starts at ₹46.25 L and the Audi Q3 at ₹43.07 L, a difference of ₹3.18 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹3.53 L. Here is what the extra money actually buys.

Engine and performance: Both cars use the same 1984cc Petrol engine and Automatic gearbox, so performance will not decide this for you. Price, features and boot space will.

Mileage and running cost: The Audi A4 Petrol Automatic is rated at 14.1 kmpl and the Audi Q3 Petrol Automatic at 10.14 kmpl. At 1,000 km a month, the Audi A4 saves you about ₹2.91 K a month and ₹34.90 K a year on fuel.

What one gives that the other does not: The Audi A4 adds Side Airbag-Rear, Additional Features, Additional Features, Rear Tread and Turbo Charger. The Audi Q3 adds Blind Spot Camera, Outside Rear View Mirror (ORVM), Leather wrap gear-shift selector, Petrol Fuel Tank Capacity and Luggage Hook & Net. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Audi Q3 if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹3.18 L for your down payment than spend it on features.

Buy the Audi A4 if you do regular highway runs, you carry luggage or a pram often, and you want Anti-lock Braking System (ABS) without waiting for the next facelift.

The one thing that settles it: Audi A4 offers Side Airbag-Rear.

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.
