Tata Sierra vs Maruti Suzuki Brezza Comparison 2026: Price, Mileage, Features

Comparison overview: The Tata Sierra starts at ₹11.49 L and the Maruti Suzuki Brezza at ₹7.40 L, a difference of ₹4.09 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹4.54 L. Here is what the extra money actually buys.

Mileage and running cost: These two figures are not like for like. The Tata Sierra number is for the Diesel/Petrol Automatic/Manual and the Maruti Suzuki Brezza number is for the Petrol/CNG Automatic/Manual, so compare the variants you are actually shortlisting.

Only the Maruti Suzuki Brezza comes with a factory CNG option at 19.8 - 21.09 kmpl, which is the cheapest way to run either car in the city.

Space and practicality: The Tata Sierra takes 622 litres against 328, about 294 litres more. That is roughly one extra cabin-size bag of extra room.

Which one should you buy?

Buy the Maruti Suzuki Brezza if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹4.09 L for your down payment than spend it on features.

Buy the Tata Sierra if you do regular highway runs, you carry luggage or a pram often, and you want useful comfort features without waiting for the next facelift.

The one thing that settles it: Maruti Suzuki Brezza has the better listed mileage.

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.
