Tata’s comeback kid has finally arrived, and it’s bigger, bolder, and far more sophisticated than anyone expected. The 2025 Tata Sierra, launched at Rs 11.49 lakh (ex-showroom), revives one of India’s most nostalgic nameplates — but with a thoroughly modern interpretation. The big talking points? A segment-shaking footprint, three engine options, and a cabin layout that feels more luxury crossover than compact SUV. Here’s a deep dive into the Sierra’s dimensions and powertrain specs, broken down in a crisp, reporter-style explainer.
Sierra Dimensions
The first thing you notice about the new Sierra is its sheer road presence. In a segment crowded with sub-4.3m crossovers, Tata has deliberately stretched the Sierra past that threshold — and it shows.
| Dimension | 2025 Tata Sierra |
|---|---|
| Length | 4340 mm |
| Width | 1841 mm |
| Height | 1715 mm |
| Wheelbase | 2730 mm |
| Boot Space | 622 litres |
At 4340 mm, the Sierra is long enough to stand toe-to-toe with bigger compact SUVs without crossing into mid-size territory. The 1841 mm width places it among the broadest in its class, which instantly translates to more shoulder room and better stability at higher speeds.
But the real ace is the 2730 mm wheelbase. It’s unusually long for a compact SUV, giving the Sierra limousine-like rear legroom. For families prioritising comfort over compact footprint, this is a huge win. And the 622-litre boot — measured up to the parcel tray — is class-leading by a mile. Weekend getaways feel less like Tetris and more like actual loading.
Overall, the Sierra’s dimensions don’t just challenge the segment — they stretch it.
Powertrain Choices
Tata hasn’t cut corners under the hood either. The new Sierra offers three engine options, giving buyers flexibility that’s increasingly rare today.
| Engine | 1.5 NA Petrol | 1.5 Turbo Petrol | 1.5 Diesel |
|---|---|---|---|
| Power | 106 PS | 160 PS | 118 PS |
| Torque | 145 Nm | 255 Nm | 260 Nm (MT) / 280 Nm (AT) |
| Gearbox | 6MT / 7DCA | 6AT (Torque Converter) | 6MT / 6AT |
1.5-Litre Naturally Aspirated Petrol
This is the entry-level workhorse — smooth, predictable, and easy on the wallet. The 106 PS / 145 Nm figures make it ideal for city usage, school runs, and daily commuting. The surprise is the 7-speed DCA dual-clutch automatic, which adds a premium edge rarely seen in base petrol trims.
1.5-Litre Turbo-Petrol
The star of the lineup. With 160 PS and 255 Nm, this engine turns the Sierra into a genuinely fun-to-drive compact SUV. The power delivery feels more European than typical mass-market turbo engines. It’s paired exclusively with a 6-speed torque converter automatic, chosen for reliability and smoother low-speed behavior.
1.5-Litre Diesel
A nod to Tata’s long-standing diesel legacy. The 118 PS output isn’t sportscar territory, but the 260–280 Nm torque spread (depending on gearbox) gives the Sierra strong mid-range punch. Available with both 6-speed manual and 6-speed automatic, the diesel Sierra will appeal to highway tourers and long-distance users who want efficiency with grunt.
The compact SUV segment has gradually shifted toward style-first crossovers. The Sierra pushes back with a more traditional SUV form — long wheelbase, chunky stance, upright glass area. That directly benefits:
- Rear seat comfort (more knee room)
- Straight-line stability
- Practical boot usability
- Better stance and proportions
Most rivals max out around 390–450 litres of boot space. The Sierra’s 622 litres resets expectations. For buyers who frequently travel with luggage, pets, strollers, or photography gear, the difference is day and night.
Retro Styling Meets 2025 Tech
The Sierra carries the unmistakable visual cues of the original — the boxy shape, wide windows, and flat tailgate. But inside, it’s very much a 2025 machine.
The dashboard features a three-screen spread:
- 12.3-inch infotainment touchscreen
- 12.3-inch passenger display
- 10.25-inch digital instrument cluster
This layout gives the cabin a futuristic, lounge-like feel. Tata has leaned into minimalism — thin vents, clean surfaces, subtle ambient lighting, and a floating centre console.
Feature List
Tata has thrown nearly everything in its arsenal at the Sierra. Feature highlights include:
- Panoramic sunroof
- Ventilated front seats
- JBL 12-speaker setup with soundbar
- 8-way powered driver seat
- Wireless charger
- Multi-color ambient lighting
- Connected car tech
It’s hard to ignore the fact that the Sierra feels like a premium mid-size SUV in feature richness, even though it’s priced squarely in compact territory.
Safety
Tata hasn’t compromised here either. The Sierra is equipped with:
- 7 airbags
- Level 2 ADAS
- Electronic stability control
- Electronic parking brake with auto-hold
- 360-degree camera
- Front + rear parking sensors
- Tyre pressure monitoring system (TPMS)
With Tata’s track record, a high crash-test rating seems almost inevitable.
The 2025 Tata Sierra is more than a nostalgic revival. It’s a statement — that compact SUVs don’t always need to shrink to fit the segment. By stretching the footprint and offering three distinct engine choices, Tata has created a highly flexible package that appeals to families, enthusiasts, and long-distance drivers alike.
The dimensions give it presence. The engines give it personality. And the features give it a premium edge. For many buyers, the Sierra could end up being the most value-packed SUV in its class — and possibly the most unique.
