The Tata Sierra ICE (Internal Combustion Engine) marks the return of India’s most nostalgic SUV brand. Unlike the concept seen at Auto Expo, the production Sierra ICE will be powered by Tata’s new 1.5-litre GDI turbo-petrol engine producing approximately 170hp. It is built on the flexible Atlas architecture, allowing for a spacious 5-seater or a flagship 4-seater “Lounge” configuration. While the Sierra EV launches first, the ICE version targets the high-performance petrol SUV segment currently dominated by the Mahindra XUV700 and Hyundai Alcazar.

What is the Tata Sierra ICE?
The Tata Sierra ICE is the petrol-powered sibling of the upcoming Sierra EV. It’s built on the Atlas (Agile Tech Forward Low-energy Architecture), a monocoque platform that replaces the heavy ladder-frame chassis of the original 1991 Sierra. While it retains the iconic curved rear glass and boxy silhouette, the ICE version is designed for highway cruising and urban luxury rather than pure heavy-duty off-roading.
It’s essentially a lifestyle choice. Most SUVs in this price bracket focus on squeezing in 7 seats. The Sierra ICE focuses on “The Lounge” experience—a unique 4-seater layout with a massive rear window and reclining seats that mimic a private jet cabin.
Tata Sierra ICE Engine Specs and Performance
The heart of the Sierra ICE is the new 1.5-litre four-cylinder GDI (Gasoline Direct Injection) turbo-petrol engine. This is a significant step up from the 1.2L Revotron engines found in the Nexon.
- Max Power: ~170 hp
- Max Torque: ~280 Nm
- Gearbox Options: 6-speed manual and a 7-speed Wet Clutch DCA (Dual Clutch Automatic).
- Drive Type: Front-Wheel Drive (FWD) at launch; All-Wheel Drive (AWD) confirmed for 2027.
Tata is prioritizing refinement here. The four-cylinder layout ensures much lower NVH (Noise, Vibration, Harshness) levels than their three-cylinder units. If you are looking for a diesel, the reality is disappointing: there is currently no confirmed diesel plan for the Sierra, as Tata is pivoting heavily toward Petrol GDI and EV powertrains for this segment.
Sierra ICE Interior: The Lounge vs. 7-Seater
The interior is where the Sierra ICE differentiates itself from the Safari and Harrier. You have three main choices:
- The Lounge (4-Seater): Two captain seats in the rear with a dedicated console and massive legroom. This version utilizes the curved rear glass to create a panoramic view.
- The Family 5-Seater: Standard bench seat with a focus on a huge boot space.
- The 7-Seater: A three-row layout designed to compete with the Mahindra XUV700.
Interior Tech Highlights:
- Twin 12.3-inch screens for infotainment and the instrument cluster.
- A four-spoke steering wheel with an illuminated logo.
- Level 2 ADAS suite (Advanced Driver Assistance Systems).
- Panoramic sunroof (with a twist to accommodate the Sierra’s signature roof rails).
How does it compare to the Sierra EV?
The biggest difference between the Sierra EV and ICE is the architecture’s focus. The EV uses the Acti.ev platform, while the ICE uses Atlas.
| Difference | Sierra ICE | Sierra EV |
|---|---|---|
| Range/Fuel | Petrol (Tank: ~50L) | ~500km Range (Expected) |
| Performance | Linear Turbo-Petrol | Instant Torque |
| Weight | Lighter (~1600kg) | Heavier due to batteries (~2100kg) |
| Best For | Long interstate road trips | City commuting & tech enthusiasts |
| AWD Type | Mechanical / Electronic | Dual Motor (e-AWD) |
Is the Sierra ICE a Mistake?
The Sierra ICE is a specialized vehicle. It’s not the right choice for everyone.
- Don’t buy it for heavy off-roading: Unlike the
tata sierra oldmodel from the 90s, this is a monocoque SUV. It will not handle extreme rock crawling like a Mahindra Thar or a Maruti Jimny. - Don’t buy it if you need a “cheap” 7-seater: The Sierra is being positioned as a premium lifestyle product. If your goal is maximum seats for minimum money, the Tata Safari or even a Maruti Ertiga is a better financial move.
- Avoid the first batch if you want AWD: The AWD version is at least 12-18 months behind the initial FWD launch. If you need four-wheel grip, wait until 2027.
