The roar you hear isn’t just a new engine, it’s the sound of Indian automotive history being rewritten. The Tata Sierra is back, and thankfully, it’s not just a facelift but a completely new launch, built on the robust ARGOS platform. It successfully fuses the unmistakable, boxy, almost vintage silhouette of the original—especially that iconic Alpine glass window design—with Tata’s cutting-edge ‘New Forever’ design philosophy.
The hype has been phenomenal, and Tata has positioned this mid-size SUV aggressively. The introductory Ex-showroom starting price immediately grabs attention, kicking off at ₹11.49 Lakh for the base Smart Plus variant. This positions it squarely in the lion’s den, directly challenging the segment leaders. But a great price is just the entry ticket. Can it justify the premium for the top-end trims? Let’s find out.
3. Quick Specs Table (Key Highlights)
Tata is offering the Sierra with an exceptional choice of three powertrains, which is a significant advantage over many rivals.
| Feature | 1.5L Turbo-Petrol (Hyperion TGDi) | 1.5L Diesel (Kryotec) | 1.5L NA Petrol (Revotron) |
| Power Output | 160 PS (158 BHP) | 118 PS (116 BHP) | 106 PS (104 BHP) |
| Max Torque | 255 Nm | 260 Nm (MT) / 280 Nm (AT) | 145 Nm |
| Transmission | 6MT / 7DCT (Dual Clutch Auto) | 6MT / 6TC AT (Torque Converter) | 6MT / 7DCT (Dual Clutch Auto) |
| Boot Space | 622 Litres (Segment Best) | 622 Litres | 622 Litres |
| Ground Clearance | 205 mm | 205 mm | 205 mm |
| Fuel Tank Capacity | 50 Litres | 50 Litres | 50 Litres |
| Seating Capacity | 5-Seater (7-Seater expected later) | 5-Seater | 5-Seater |
Note: The 1.5L Diesel AT with 280Nm torque is a class-leading figure, giving it a powerful edge.
4. Exterior Design & Road Presence
The Revival of the Boxy Charm
The Sierra’s design is a masterful nod to its past while being firmly rooted in the future. In an age of swoopy, coupe-like SUVs, the Sierra maintains a confident, upright, and boxy stance that gives it tremendous road presence. It is wider (1841mm) and taller (1715mm) than most of its direct rivals, which immediately translates to a dominating figure on the road.
- Front End: It features the signature connected LED light bar across the width, similar to the new Nexon, but here it looks more mature and imposing. The main Bi-LED Booster headlamps are vertically placed lower on the bumper, a design element Tata is using to create a distinct family look.
- Side Profile: This is where the magic happens. The design retains the original Sierra’s unmistakable Alpine Window (that large, wrap-around rear glass section). While the B-pillar is now blacked-out rather than fully transparent glass like the original, the effect is stunning. The flush door handles (on higher trims) and the large, impressive 19-inch Magnum Alloy Wheels (on top variants) complete the premium look.
- Overall Stance: Does it turn heads? Absolutely. People stop and stare, mostly due to the sheer size and the nostalgic familiarity of the name. The high 205mm ground clearance ensures it doesn’t just look like an SUV but is ready to take on bad Indian roads.
5. Interior, Comfort & Features
If the exterior is a nod to the past, the interior is a massive leap into the future. Tata has loaded the Sierra with technology and premium touches that genuinely push the segment benchmark.
The Triple-Screen Cockpit
- Dashboard & Tech: The biggest talking point is the ‘Horizon View’ Triple-Screen Setup. You get a dedicated 10.25-inch Digital Instrument Cluster, a large 12.3-inch Central Infotainment Touchscreen, and, on the top-end, a separate 12.3-inch Passenger Display (with wireless headphones!) which is an industry-first in this segment. The material quality feels premium—soft-touch plastics on the top dash and door pads, and high-quality leatherette upholstery. The four-spoke steering wheel with the illuminated Tata logo is a delight to hold.
- Infotainment: The infotainment system is powered by the new iRA Connected Car App with 5G connectivity and even an ‘Arcade Suite’ for entertainment—a clear focus on tech-savvy buyers. The 12-speaker JBL sound system with a dedicated soundbar and Dolby Atmos is brilliant and easily the best audio experience in this class.
Space & Comfort: Can 3 People Sit at the Back?
The Sierra truly shines when it comes to cabin space. The generous length and class-leading 2730mm wheelbase mean there is ample legroom and shoulder room.
- Rear Bench: The Sierra is arguably one of the most comfortable SUVs in the segment to seat three adults abreast. The cabin width (1841mm) provides significantly better shoulder room than a Creta or Seltos. The floor is relatively flat, and the presence of Rear AC Vents and 65W fast-charging USB-C ports is a welcome addition.
- Features that Matter: The top trims come with a huge Voice-Assisted Panoramic Sunroof, Dual-Zone Automatic Climate Control, and Ventilated Front Seats—all must-have features in this segment, and Tata has ticked every box. Missing features? A small niggle is the slightly bulky size of the gear lever in the Automatic variants, but that is quickly forgotten once you use the paddle shifters.

6. Engine Performance & Driving Dynamics
I tested both the 1.5L Turbo-Petrol and the 1.5L Diesel powertrains. The power figures are impressive on paper, but how does it feel on the road?
The Turbo-Petrol Punch: Hyperion TGDi
The all-new 1.5L Turbo-Petrol (Hyperion TGDi) producing 160 PS and 255 Nm is the star of the show.
- Highway Drive: This engine feels punchy and refined. The power delivery is strong and linear, especially once the turbo spools up after 2,000 rpm. Maintaining 100kmph+ is effortless, and the SUV feels absolutely rock-steady on the highway, with minimal cross-wind disturbances. The 7-speed DCT (Dual Clutch Transmission) is smooth for the most part, though a slight hesitation can be felt at very low speeds, a characteristic common to most DCTs.
- City Drive: The steering is light and thankfully not overly assisted, which makes maneuvering the large body in traffic surprisingly easy. The clutch action on the Manual Transmission is light and progressive, which will be a boon in bumper-to-bumper city traffic. Yes, the Sierra is a large vehicle, but the excellent 360-degree camera system and front parking sensors make parking in tight spots far less stressful than expected.
Suspension: Handling the Indian Potholes
This is where Tata usually shines, and the Sierra is no different. The suspension setup, which features a sophisticated ‘Superglide’ suspension with frequency-dependent damping on top trims, is tuned for comfort.
- Comfort Focus: The suspension absorbs potholes easily. Even the sharpest ridges and broken tarmac sections are filtered out with a muted thud, without crashing into the cabin. There is a noticeable trade-off: in enthusiastic cornering, you will feel some body roll. However, the long wheelbase and wide stance keep it controlled, and this slight roll is a small price to pay for the exceptional ride comfort it offers over varied Indian road conditions.
7. Safety (Crucial Section)
Tata Motors has built its recent reputation on safety, and the Sierra comes with a host of segment-defining features.
- Build Quality: While an official Global NCAP rating is pending, the robust build on the ARGOS platform gives confidence. The sheer heft and build solidity are palpable—you feel secure inside the cabin. Given Tata’s track record (Nexon, Punch, Harrier/Safari), a 5-star rating is highly anticipated.
- Airbags & Essentials: It comes standard with 6 Airbags, along with ABS, EBD, and ISOFIX child seat mounts.
- L2+ ADAS Suite: On the top trims, the Sierra introduces an advanced Level 2 ADAS (Advanced Driver Assistance System) suite with 22 intelligent features, including:
- Front Collision Warning (FCW)
- Adaptive Cruise Control (ACC)
- Lane Keep Assist (LKA)
- Dual Blind Spot Detection
- Electronic Stability Program (ESP) with 21 functions
The inclusion of an electronic parking brake with auto-hold further enhances convenience and safety, especially in city-gradient traffic.
8. Real World Mileage (The Truth)
Mileage, or kitna deti hai, is the ultimate question in the Indian market. Tata’s new Hyperion engine has created a buzz by achieving a record-breaking 29.9 kmpl under controlled NATRAX testing. However, we all know that’s lab-fiction.
| Variant | ARAI Claimed Mileage (Approx.) | Real World City Mileage (Expected) | Real World Highway Mileage (Expected) |
| 1.5L Turbo-Petrol DCT | $\approx 18.0 \text{ kmpl}$ | 9.0 – 10.5 kmpl | 13.5 – 15.0 kmpl |
| 1.5L Diesel MT | $\approx 22.0 \text{ kmpl}$ | 12.0 – 14.0 kmpl | 17.0 – 19.5 kmpl |
| 1.5L NA Petrol MT | $\approx 17.5 \text{ kmpl}$ | 10.0 – 11.5 kmpl | 15.0 – 16.5 kmpl |
- The Diesel is the Efficiency King: If mileage is your number one priority, the 1.5L Diesel Manual is the clear winner. The real mileage in city traffic for the diesel manual is a respectable 12-14 kmpl, which is very competitive for an SUV of this size.
- Turbo-Petrol Reality: The Turbo-Petrol, though powerful, will be thirsty. Expect the real mileage in city traffic to hover between 9.0 and 10.5 kmpl. Given the power it generates, this is acceptable, but buyers must manage their expectations relative to the 29.9 kmpl stunt.

Winner: Which one provides better Value For Money (VFM)?
For the first time, an Indian contender genuinely challenges the Korean dominance not just on price, but on product.
- Choose the Creta/Seltos if: You prioritize a slightly more refined (but less powerful) turbo-petrol/diesel combination and don’t mind the slightly cramped rear seating for three. Their resale value is also established.
- Choose the Tata Sierra if: You want class-leading Space (622L boot and huge cabin), the most powerful engine in the segment (280 Nm Diesel torque is brilliant), and a feature set (Triple-Screen, JBL Audio, L2 ADAS) that is either segment-best or segment-first. The Sierra offers significantly better VFM due to the space, power, and commanding road presence you get for the starting price.
10. FINAL VERDICT
The new Tata Sierra is much more than just a nostalgic revival. It’s a supremely competent, segment-leading product that excels in the three areas that matter most to the Indian buyer: Road Presence, Space & Comfort, and Safety. Tata has done its homework, and the inclusion of the powerful Turbo-Petrol engine and the best-in-class boot space (622L) makes it a seriously compelling package.
The only real trade-off is the slight body roll due to the comfort-focused suspension setup, but for 95% of buyers, the plush ride quality on bad roads is a far greater priority. Is it worth the price tag? Absolutely. It undercuts the starting price of its key rivals while offering more car.
Buy it if:
- You prioritize Space and Comfort (Best-in-segment rear bench and boot space).
- You want the most Powerful and Torquey Diesel engine option in the segment (280 Nm).
- Safety and Build Quality are non-negotiable for you (High safety expectations, L2+ ADAS).
Skip it if:
- You demand absolute, sporty, Minimal Body Roll handling for aggressive driving.
- You expect extremely high fuel economy figures from the Turbo-Petrol in heavy city traffic.
- You cannot wait for the inevitable waiting period that will follow this blockbuster launch.
My Score: 9.0/10
