We’ve said in the past, the Sierra is the best Tata model on sale currently, representing the best of the brand’s learnings over the years. We’ve also said Tata’s electric powertrains are better than the equivalent combustion engines on offer. So, combine the two, and it’s undoubtedly a winning formula. But with EV tech and customer expectations moving so rapidly these days, is that necessarily a foregone conclusion?

2026 Tata Sierra EV exterior design and engineering – 9/10

Retains the ICE version’s sharp looks and practicality while incorporating a large battery.

The new Sierra is a bold piece of design, and this has been carried over to – and perhaps even improved – on the electric version. It’s a welcome departure from the notion that all EVs need to be shaped like bars of soap for better aero efficiency. Instead, it is upright and boxy, albeit smoothed out just enough for air to flow over it a bit better.

The difference is up front, where the gloss black surround for the headlamps found in the ICE version has been replaced by a body-coloured panel to give that EV-typical ‘grille-less’ look. For contrast, the gloss black treatment has been applied lower down in the bumper instead. Perhaps the wheels could have been more different – they are the same design as the ICE model, albeit in a matte finish rather than gloss. The badges now say ‘Sierra.ev’ on the sides and rear, and have a blue-coloured outer edge.

To the untrained eye, it might not immediately be apparent which version is which, but conversely, this is unmistakably a Sierra, and that is perhaps more important.

Little practicality has been lost in the move to electric; in fact, some has been gained. Almost as if to drive the point home that, despite the similar looks, this is a pure EV underneath, it gets a frunk that holds 55 litres in the single-motor models, and 35 litres in the dual-motor version. Good enough for the charging cable or small valuables you don’t want to keep in the main boot. 

There’s also still 205mm of ground clearance, despite the battery pack, and thanks to its use of prismatic cells and C2P (cell to pack) packaging, it doesn’t weigh or impede on cabin and boot space as much as conventional batteries of similar capacity (like the ones in the Harrier EV).

2026 Tata Sierra EV interior space and comfort – 7/10

Superb space and comfort, though quality inconsistencies and ergonomic gaffes remain.

However, while boot space has been retained at a cavernous 622 litres (floor to roof), a casualty of the battery pack is the spare wheel, which was previously mounted under the body. You now only get a puncture repair kit.

There’s seemingly no compromise to space or comfort in the cabin in the move to electric power. Engineers say the floor height has gone up by less than an inch compared to the ICE Sierra, and in truth there is no perceptible difference when you’re sat in the back seat. It remains spacious and comfortable, and even gets a small amount of backrest recline. The awkward L-shaped B-pillar returns, leaving a conspicuous gap next to the sun blind that could have easily been avoided. As before, you get a gigantic sunroof on top-spec trims that lets in a lot of light.

Up front, the lounge-like ambiance remains, with a cream-coloured, leatherette-bound dashboard and a textured fabric surface for the ‘sound bar’ central speaker. The three-screen stack adds a techy vibe to this atmosphere, and between the seats is a pedestal for the drive selector. The front seats are very comfortable and offer a good amount of shoulder support – something often overlooked in seat design.

For every soft surface and attractive trim piece, however, there is visible hard plastic, rough edges, crooked stitching and misaligned panel fit, which are an eyesore, especially at this price. And while the design is attractive, its execution could have been far better considered from a practicality and ergonomics standpoint. For example, the pedestal-mounted drive selector is set at a comfortable height, but wastes the space below it. Consequently, the storage box behind it is narrow, tall and harder to reach, while the cupholders are tiny and forced to the base of the dashboard. And while the inclusion of small umbrella holders in the door cards is a nice touch, there is no drain plug, so surplus water will collect in the door pockets. Good intentions; poor execution.

2026 Tata Sierra EV features and safety – 9/10

Packed to the gills with safety and tech, more so even than the ICE version.

Tata in the last few years has caught up to the features freight train that has the Indian car industry in a stranglehold. The Sierra EV is, thus, one of if not the best equipped in its segment, with every conceivable gizmo imaginable on the top-spec Empowered A variant. And as always, the EV gets a small edge on its ICE counterpart, which comes in the form of a powered front passenger seat, as well as an HUD alongside the three-screen layout (instead of either one or the other).

Those front seats are ventilated too, and the driver gets a memory function. There’s a full ADAS suite, drive modes, regen modes and terrain modes, the panoramic sunroof, dual-zone auto climate control, a 12-speaker JBL Black sound system with Dolby Atmos, an onboard air purifier, connected car tech and much, much more. There’s also a clever integration with Google Maps that predicts what the car’s SOC will be when you reach your destination, helping you plan better. 

The screens are crisp and smooth in their animations, although as before, the 10.25-inch driver’s display feels a bit too cluttered; the HUD actually provides a cleaner and more focused driver display. And while Tata is not the first brand to do it, the passenger screen feels like a gimmick, more so now that there is a multiplayer gaming suite that lets all passengers connect their phones to the car and play from their own device.

While there hasn’t been a crash test of the EV specifically, the ICE Sierra scored a 5-star Bharat NCAP rating, which should feasibly carry forward to this car too. Apart from an extensive ADAS suite on the top trim, there are 6 airbags as standard, as well as several other safety features.

2026 Tata Sierra EV performance and refinement – 8/10

Dual-motor QWD version brings AWD to the segment and delivers class-best performance.

The Sierra EV can be had in one of three powertrain configurations – a 63kWh battery with a rear motor, a 75kWh battery with a rear motor, or the one we’ve got to test drive – the 75kWh battery with dual motors. This makes the Sierra the first to bring AWD to this segment and is, expectedly, the most potent version, with a class-leading output of 306hp and 504Nm. Despite weighing in at around 2.1 tonnes, the SUV can sprint to 100kph from a standstill in a claimed 5.8sec. However, while it is undoubtedly capable of that, it doesn’t feel neck-snappingly quick off the line. Instead, it is quite undramatic, and frankly that is fine in a family SUV such as this. It’s a smooth and refined powertrain, as we’ve come to expect from Tata Motors’ EVs over the years.

That said, it perhaps feels a bit too similar to older Tata EVs, considering this is a new-generation model. Where newer EVs now have greater responsiveness off the line, this one still has a small dead zone at the start of the pedal travel, after which power comes in abruptly, and this requires care in stop-go traffic. Thereafter, it’s delivered in a constant lump of torque, where others have managed to program in some sort of progression. A minor criticism, and it’s still a far better experience than any ICE powertrain, but the EV game has since moved on.

There are drive modes, though apart from a noticeable dullness in Eco mode, the rest – City, Sport and Boost – don’t feel too different from one another. Similarly, the regen modes – easily accessible using the steering-mounted paddles – don’t feel all that different from one another.

The Sierra EV QWD was rather impressive on the off-road course Tata Motors set up for it, which wasn’t the usual walk in the park, and had some pretty significant obstacles. Put it down to the short overhangs that improve approach and departure angles, or the responsiveness of the e-motors, but the result was surprisingly effortless. We didn’t even need to delve into the terrain modes for the most part, though there were instances where it would fumble shifting torque between the left and right wheels mid obstacle.

2026 Tata Sierra EV range and efficiency – 8/10

Big battery means big numbers, though a real-world test remains.

63kWh and 75kWh are among the bigger batteries offered in this segment, with only the Mahindra BE 6 offering a larger 78kWh unit. The Sierra’s smaller pack is rated at 565km on the MIDC, while the larger at 665km for the single motor and 624km for the dual motor. Tata itself says the MIDC rating won’t be achieved in real-world use, but that the larger battery can deliver upwards of 500km realistically.

When it comes to charging, on a 7.2kW AC charger, the 63kWh pack will take 8.9 hours to get from 10-100 percent, while the 75kWh pack will take 10.5 hours. On a 120kW DC charger, meanwhile, both will do a 20-80 percent top-up in about 26 minutes. At what rate the car actually accepts charge, however, remains to be seen. Tata offers a 15-year warranty on the battery of the Sierra EV, which is reassuring.

2026 Tata Sierra EV ride comfort and handling – 8/10 

No compromise on comfort, despite added weight. Handles amicably too.

Tata SUVs have always been great in the dynamics department, and that continues here too. Despite the 19-inch wheels and the 2.1-tonne kerb weight, the Sierra EV can handle any manner of surface with equal composure and comfort. Put it down to the frequency dependent dampers (FDD) but no pothole is too big, nor surface too broken to upset the SUV.

It holds its line well at high speeds and lane change manoeuvres can be made with confidence and little effort. Similarly, at low speeds, the steering is light without feeling loose, letting you change direction easily even in traffic.

High-speed handling too is also pretty engaging, helped no doubt by its lower centre of gravity, and if you really wanted to, you could lean onto the Sierra EV quite hard. That said, it is a tall, high-riding vehicle, so an acceptable amount of body roll is present. The boxy profile, however, does result in some wind noise around the A-pillars at high speed, made more apparent by the silent powertrain.

2026 Tata Sierra EV price and verdict – 7/10

Overlaps with Curvv and Harrier, but feels the better EV than either of them.

It’s not much of a surprise that the Sierra EV is the best Tata you can buy right now, as it the latest product of the brand’s strategy of constant evolution and improvement. It’s not without its flaws, of course, but these feel less like huge deal breakers, and more like matters of finesse in manufacturing and calibration that Tata should take the time to address.

Apart from being a great EV, it’s also just a very good family car, offering space, comfort and the features Indian buyers now expect. The bigger problem for Tata could be where it fits between the Curvv and Harrier EVs, because there is some price overlap, and in our opinion, it surpasses them both overall. And while, at Rs 18.79 lakh to Rs 25.99 lakh, it is priced at the upper end of its segment, it does pack in a lot, and sits on par with the BE 6, which doesn’t have an AWD variant. Which of these two is better is a question for another time, but for now, the Sierra EV has the makings of a winner.
