The 2025 Tata Sierra has been introduced by Tata Motors, with starting prices of Rs 11.49 lakh (ex-showroom). Smart+, Pure, Pure+, Adventure, Adventure+, Accomplished, and Accomplished+ are the seven versions that will be available. After a brief discussion of its safety features, let’s look at all the color options and variant-wise options for the new Sierra. Tata Motors’ revived Sierra has arrived with a modern look, three-screen cabin and multiple 1.5-litre engine options — but what will its mileage be like on Indian roads? Short answer: official ARAI numbers for the all-new Sierra aren’t widely published yet; early spec sheets and launch coverage show petrol and diesel 1.5-litre options, and real-world economy will depend heavily on engine, transmission and driving conditions

Tata Sierra EV Mileage / Range
Based on the cutting-edge Acti.EV architecture, the Tata Sierra EV is anticipated to be the standout model in the lineup. These forecasts are based on the platform’s capabilities and Tata’s most recent EV range accomplishments:
450–550 km on a single charge is the anticipated range (ARAI).
Range in the real world: 380–450 km
Battery Pack: Probably between 60 and 65 kWh
DC Fast Charging: 10–80% in about 40–50 minutes
These numbers make the Sierra EV a formidable rival to the MG ZS EV and the upcoming Hyundai Creta EV, placing it on par with contemporary long-range electric SUVs.
Tata Sierra Petrol Mileage (Expected)
To appeal to buyers of conventional SUVs, Tata may also introduce the Sierra with a 1.5L turbo-petrol engine. Calculated mileage using comparable Tata engines:
11–13 km/l in the city
15–18 km/l on the highway
ARAI’s total mileage is 14–16 km/l.
For a mid-size premium SUV, the engine should provide strong performance with reasonable efficiency.
Engines & why mileage varies
In addition to naturally aspirated and diesel 1.5-liter options with manual and automatic gearboxes, the 2025 Sierra lineup includes a 1.5-liter turbo-petrol (tGDi) with about 168 horsepower. Fuel efficiency will vary significantly depending on the setup: diesel models typically provide the best kmpl on highways, naturally aspirated petrols return steadier economy in city driving, and small turbocharged petrols tend to be brisk but thirstier under heavy loads. These engine options are listed on early spec pages and launch writeups, but they also indicate that final certified cycle numbers were still being verified at launch.
Official vs. real-world numbers
A number of dealer and media listings for the Sierra either mark mileage as “to be announced” or omit ARAI figures. As a result, published launch specifications might not yet include the official certified kmpl. This is typical for recently relaunched models, where variant-level certification comes after announcements about pricing and configuration. Expect a discrepancy between stated numbers and what you’ll see on a daily basis until Tata releases official ARAI ratings: When compared to steady highway cruising, city driving (stop-start, AC on) usually results in a 15–30% decrease in fuel efficiency.
Features and Safety
The 2025 Sierra comes equipped with features such as a 12.3-inch infotainment system with wireless Android Auto and Apple CarPlay, 10.25-inch digital driver’s display, and an additional 12.3-inch display for front-row passenger. Additional features include, ventilated front-row seats, dual-zone climate control, a 12-speaker JBL sound system, and keyless entry with push-button start/ stop.Safety features include, six airbags as standard, ABS with EBD, electronic stability control, hill assist, ISOFIX child seat mounts, a 360-degree camera system with front and rear parking sensors, tyre pressure monitoring, and Level 2 ADAS. Here’s a detailed breakdown of the features you get with every Tata Sierra variant.

While the prices of all the variants are yet to be disclosed, the introductory price of the 5-door SUV is tagged at Rs 11.49 lakh (ex-showroom).
Why Mileage Matters for Sierra Buyers
Mileage plays a key role in the premium SUV segment, especially as buyers compare options like the Hyundai Creta, Kia Seltos, MG ZS EV, and upcoming Mahindra BE series. The Sierra’s competitive fuel efficiency can make it a strong contender for customers who want an SUV that’s stylish, futuristic, and economical to run.
