The Tata Sierra has returned as a modern five-seat SUV, bringing back one of Tata Motors’ most recognisable nameplates with a completely new design, modern technology and multiple petrol and diesel powertrain options.
The new Sierra sits between the Tata Curvv and Tata Harrier in Tata Motors’ SUV lineup. It combines a distinctive boxy design with features such as a panoramic sunroof, large infotainment displays, connected-car technology and advanced driver-assistance features on higher variants.
As of September 2026, the Sierra is available with naturally aspirated petrol, turbo-petrol and diesel engines, along with manual and automatic transmission options. Tata has also introduced newer editions of the SUV, including the Legend Series and Dark Edition.
Tata Sierra 2026 Price
The Tata Sierra is currently priced from approximately ₹11.49 lakh to ₹21.59 lakh ex-showroom, depending on the variant and powertrain. The exact price varies significantly between petrol, turbo-petrol and diesel versions.
The Sierra is offered across a large number of variants, giving buyers several combinations of engine, transmission and equipment. Current variant listings include Smart+, Smart+ L, Pure, Pure L, Pure L(O), Pure+ L, Adventure+, Adventure+ L, Accomplished and Accomplished+ trims, along with Dark variants.
Because on-road prices depend on the city, RTO charges, insurance and other costs, buyers should check their local on-road price before making a purchase.
Tata Sierra 2026 Engine Options
One of the biggest strengths of the Sierra is its choice of powertrains.
The SUV is available with three 1.5-litre engine options:
1.5-litre Naturally Aspirated Petrol
- Displacement: 1,498cc
- Power: around 106hp
- Torque: 145Nm
- Transmission: 6-speed manual / DCT depending on variant
This engine is aimed at buyers who want a naturally aspirated petrol option for regular city and highway use.
1.5-litre Turbo-Petrol
- Displacement: 1,498cc
- Power: around 160hp
- Torque: 255Nm
- Transmission: automatic options depending on variant
The turbo-petrol is the performance-oriented petrol option in the Sierra lineup.
1.5-litre Diesel
- Displacement: 1,497cc
- Power: around 118hp
- Torque: up to 280Nm with automatic transmission
- Transmission: 6-speed manual / 6-speed automatic
The diesel version is particularly relevant for buyers who regularly travel long distances and are looking for higher claimed fuel efficiency.
Tata Sierra Mileage
Claimed mileage varies according to the engine and transmission.
According to current published specifications, the Sierra’s claimed mileage is approximately:
| Powertrain | Claimed Mileage |
|---|---|
| Petrol Manual | Up to 17.4 kmpl |
| Petrol DCT | Around 16.9 kmpl |
| Petrol Automatic | Around 15.3 kmpl |
| Diesel Manual | Up to 21.26 kmpl |
| Diesel Automatic | Around 19.22 kmpl |
Actual mileage will depend on traffic, driving style, road conditions, air-conditioning use and vehicle load. Claimed/ARAI figures should therefore not be treated as guaranteed real-world mileage.
Tata Sierra Dimensions
The Sierra is designed as a mid-size SUV and has a relatively long wheelbase aimed at providing good cabin space.
Key published dimensions include:
- Length: 4,340mm
- Width: 1,841mm
- Height: 1,715mm
- Wheelbase: 2,730mm
- Ground clearance: 205mm
- Seating capacity: 5

The large boot and five-seat configuration make the Sierra particularly relevant for family buyers looking for an SUV with everyday practicality.

The Sierra gets a long list of features, although equipment varies significantly by variant.
Some of the notable features available across higher trims include:
- Panoramic sunroof
- Large touchscreen infotainment system
- Digital instrument cluster
- Passenger-side infotainment display

Higher variants get considerably more technology and premium equipment than the entry-level versions.
Tata Sierra Interior
The Sierra’s cabin is designed around a technology-heavy dashboard.
One of its standout elements is the three-screen setup on higher variants, consisting of the driver’s display, central infotainment screen and passenger display.
Higher trims also offer premium equipment such as a panoramic sunroof, powered seats, ventilated seats, wireless charging and premium audio.
However, buyers should compare variants carefully because many of the most advanced features are not available on the entry-level Sierra.
Tata Sierra Safety
Safety is one of the major talking points around the new Sierra.
The SUV has received a 5-star Bharat NCAP safety rating, according to current reports. It also offers safety equipment such as airbags, electronic stability control, ABS and EBD, with more advanced driver-assistance technology available on higher variants.
Higher variants can be equipped with features including:
- ADAS
- 360-degree camera
- Blind-spot monitoring
- Adaptive cruise control
- Driver assistance systems
- Electronic stability control
- Multiple airbags
Feature availability depends on the specific variant.
Tata Sierra Variants
The Sierra range is extensive, with several trim levels.
Smart+
The Smart+ serves as an entry point into the Sierra range and includes basic exterior and safety equipment.
Pure
The Pure adds more convenience and technology features, including a larger infotainment system and smartphone connectivity.
Pure L / Pure L(O)
These variants add more equipment and are positioned higher in the range.
Adventure+
Adventure variants add features such as larger wheels, panoramic sunroof and additional cabin technology depending on the exact version.
Accomplished
The Accomplished variants sit near the top of the range and bring more premium equipment.
Accomplished+
The Accomplished+ is among the highest Sierra trims and includes advanced features such as ADAS, premium audio, powered tailgate, seat memory and other premium equipment depending on the powertrain.
Tata Sierra Boot Space
The Tata Sierra offers a claimed 622-litre boot, giving it a substantial amount of luggage space for a five-seat SUV.
This can be useful for families carrying multiple bags during road trips or regular travel.
The flexible cargo area also adds practicality for everyday use.
Tata Sierra Ground Clearance
The Sierra has approximately 205mm of ground clearance.
This should help when dealing with uneven roads, speed breakers and rougher urban surfaces, although ground clearance alone does not determine a vehicle’s off-road capability.
Tata Sierra: Petrol vs Diesel
Choosing between petrol and diesel depends largely on how the SUV will be used.
Petrol may suit buyers who:
- Mostly drive in the city
- Have relatively lower annual running
- Prefer a quieter petrol powertrain
- Want the turbo-petrol performance option
Diesel may suit buyers who:
- Drive long distances regularly
- Spend significant time on highways
- Want higher claimed fuel efficiency
- Prefer the stronger low-end torque of a diesel
The total ownership cost should be considered rather than choosing purely based on mileage.
Tata Sierra Automatic Options
The Sierra is available with automatic transmission options depending on the engine and variant.
Petrol versions can be paired with automatic options including DCT, while diesel variants are available with a torque-converter automatic on applicable trims.
This gives buyers more flexibility depending on whether their priority is city driving, highway use or performance.
Tata Sierra: Who Should Consider It?
The Sierra could be relevant to buyers looking for:
- A five-seat family SUV
- A distinctive exterior design
- A spacious boot
- Petrol and diesel choices
- Automatic transmission options
- Modern infotainment technology
- Advanced safety features
- A feature-rich cabin
However, buyers should compare the exact variants before purchasing because equipment differs considerably across the range.
Tata Sierra vs Rivals
The Sierra competes in the broad mid-size SUV space and can be compared with models such as:
- Hyundai Creta
- Kia Seltos
- Mahindra XUV 3XO
- Tata Curvv
- MG Astor
- Maruti Suzuki Grand Vitara
- Toyota Urban Cruiser Hyryder
The right comparison depends on budget, engine preference, size, features and intended usage.
