The Tata Sierra is back, and it has quickly become one of the most exciting mid-size SUVs of 2025. The SUV stands out not only because of its modern-retro design and premium triple-screen cabin but also because of its new turbo-petrol engine, which is getting a lot of attention for its expected fuel efficiency.
Below is an easy-to-read and informative breakdown under your main subheads, covering everything from the turbo-petrol engine to mileage, specs, and real-life performance.
Tata Sierra Turbo Petrol
The biggest highlight of the new Sierra is its 1.5-litre TGDi turbo-petrol engine. It makes around 160 PS and 255 Nm, giving the SUV strong mid-range power and smooth acceleration. Tata has tuned this engine to offer good pick-up for daily drives while still keeping fuel economy in check.
This turbo-petrol is meant for buyers who want both power and practicality in city and highway driving.
Tata Sierra Fuel Efficiency
Many auto reports suggest that Tata has focused heavily on making the Sierra’s turbo-petrol model as fuel-efficient as possible. The use of a smaller engine size, direct injection technology, and updated engine controls helps it deliver better mileage than most turbo-petrol SUVs in this segment.
However, like any new car, the real story will come from actual user feedback once people begin driving it daily. The early buzz is strong, but real-world numbers will confirm how close the claimed figures are to everyday performance.

Tata Sierra Specifications
The 2025 Sierra is built on Tata’s new ARGOS platform, which supports both petrol/diesel engines and future electrified powertrains. This platform allows better safety, performance, and interior space.
Key highlights include :
- Multiple engine options : 1.5 NA petrol, 1.5 TGDi turbo petrol, and 1.5 diesel
- Safety features : Multi-airbags, ESP, traction control, and ADAS in higher variants
- Premium cabin : A unique triple-screen setup, modern dashboard, and spacious seating
- Gearbox options : Manual and automatic choices across variants
Pricing starts from ₹11.49 lakh (ex-showroom), putting the Sierra in direct competition with the Hyundai Creta, Kia Seltos, Maruti Grand Vitara, and similar midsize SUVs.
Tata Sierra 2025 Turbo Petrol Mileage
Early reported numbers suggest that the turbo-petrol Sierra may deliver around 16–17 kmpl (ARAI estimated). These figures make it one of the more efficient turbo-petrol SUVs in its class.
Realistically, expect :
- City mileage : Slightly lower due to traffic and stop-go conditions
- Highway mileage : Higher than ARAI numbers when cruising at steady speeds
These early estimates place the Sierra in a very competitive position, especially for buyers who want petrol convenience but still care about mileage.
Tata Sierra Performance
The 1.5 TGDi engine offers solid performance that suits both city driving and long-distance travel. With 255 Nm of torque, the Sierra can overtake easily on highways and doesn’t require constant gear shifts in traffic.
- The NA petrol is more basic and budget-friendly.
- The diesel continues to be the best for long-distance and fuel-conscious buyers.
Tata has tuned the suspension to offer a comfortable ride, making the Sierra more family-friendly rather than sporty. The higher ground clearance also adds confidence on rough or broken roads.
Who Should Consider the Sierra
- Family & City Buyers: Panoramic sunroof, triple screens, ADAS, and strong safety make it a practical family SUV.
- Mileage-Focused Buyers: Diesel gives the best mileage; turbo-petrol also offers impressive efficiency.
- Power + Economy Buyers: The 1.5 TGDi turbo-petrol delivers strong performance with good claimed mileage.
The 2025 Tata Sierra brings back an iconic name with a perfect mix of old charm and new-age tech. Its turbo-petrol engine is the real star, offering strong performance while aiming to be one of the most fuel-efficient turbo-petrol SUVs in India.
While actual user-tested mileage will tell the full story, early figures and technology suggest that the Sierra is well on its way to becoming a top choice in the midsize SUV segment.
