Tata Sierra — Price, Mileage, Variants & Expert Review

Start at the tailgate: a powered boot opening onto up to 1,257 litres of cargo volume with the seats down — van-grade space in a 4,340 mm SUV. The Sierra earns it with a 2,730 mm wheelbase (longer than most of the next size class up) and an 1,841 mm-wide body, so the five seats inside are properly spaced before the luggage argument even begins. Add 205 mm of ground clearance, a panoramic sunroof, flush door handles and ADAS on upper trims, and this is Tata packaging a family car with unusual generosity.

The engine board gives three distinct answers across 24 variants at ₹11.49-21.29 lakh: a 106 PS 1.5 Revotron petrol for the budget rows, a 118 PS/260 Nm 1.5 Kryojet diesel with a 6-speed automatic option for the high-milers, and the 160 PS/255 Nm 1.5 TGDi Hyperion turbo-petrol — automatic only — that pushes the range to a healthy 13.9 PS per lakh. One honest gap: no claimed mileage figures are listed for any engine yet, so running-cost planning needs a real-world test drive rather than a brochure. It enters as the 33rd-cheapest of 144 SUVs in its segment (median ₹39.5 lakh), which is aggressive for the space on offer.

Sierra vs Rivals

Sierra vs Mahindra Bolero Neo Plus: From ₹11.39 lakh with nine seats and a 280 Nm diesel — carries people where the Sierra carries luggage. See the Mahindra Bolero Neo Plus.

Sierra vs Honda Elevate: From ₹11.6 lakh, petrol-only at a published 16.92 kmpl — simpler, proven, and far less spacious in the boot. See the Honda Elevate.

Sierra vs Toyota Urban Cruiser Hyryder: From ₹11.31 lakh with a 27.97 kmpl hybrid claim — the running-cost benchmark the Sierra cannot yet answer on paper. See the Toyota Urban Cruiser Hyryder.

Sierra vs Kia Carens Clavis: From ₹11.23 lakh with petrol and diesel at up to 19.54 kmpl — the three-row MPV alternative at the same entry money. See the Kia Carens Clavis.

GaadiInfo Verdict

The Sierra's case is space-per-rupee and it makes it convincingly — nothing at this entry price matches the wheelbase-plus-boot combination. Buy from the middle of the range: a mid-trim diesel AT if you clock serious kilometres, or a mid-trim Revotron petrol if you are city-bound and want the space cheaply. The 160 PS Hyperion trims are genuinely quick for the class but push past ₹20 lakh, where the value story thins. Whatever you choose, insist on a proper extended test drive to gauge fuel behaviour yourself, because the brochure will not tell you.

• Decide engine first — 106 PS petrol for city duty, 118 PS/260 Nm diesel for highway miles, 160 PS turbo for pace — then find the cheapest trim carrying your must-have features; that collapses 24 variants to about three
• Since no claimed mileage is published, run your own highway-plus-city test loop and log the trip computer before signing
• At PDI, cycle the powered tailgate and flush door handles several times, check panoramic sunroof drainage, and verify the ADAS calibration sticker/status on trims that carry it

Frequently asked questions

What is the Tata Sierra's price range in 2026?

₹11.49 lakh to ₹21.29 lakh (ex-showroom) across 24 variants with three engine options — petrol, diesel and a 160 PS turbo-petrol.

How big is the Tata Sierra's boot really?

Up to 1,257 litres of listed cargo volume — a seats-folded figure that puts it in van territory. Higher trims add a powered tailgate.

Which Sierra engine suits a mix of city and highway?

The 118 PS, 260 Nm Kryojet diesel with the 6-speed AT if you cross 1,500 km/month; otherwise the 106 PS Revotron petrol keeps the entry price honest. The 160 PS Hyperion is the performance pick, AT-only.

What mileage does the Tata Sierra give?

Tata has not published claimed figures for any Sierra engine in the current data. Take an extended test drive and log the trip computer — do not buy this car on assumed economy.

Does the Sierra have ADAS and a panoramic sunroof?

Yes — upper trims carry ADAS, a panoramic sunroof, rain-sensing wipers, cornering fog lamps and full-LED lighting.

Is the Sierra bigger inside than other SUVs at this price?

Its 2,730 mm wheelbase and 1,841 mm width lead the immediate price band, which shows up as rear-seat space. Only three-row MPVs offer more total room, and they trade away the boot.
