Tata Motors launched the fully electric version of the Sierra on June 30, 2026. Spread across three distinct variants, the Sierra EV joins the automaker’s all-electric line-up and is slotted between the Curvv EV and Harrier EV. The Harrier EV and Sierra EV are in a similar price bracket, with clear price overlaps between some trim levels, with the top-spec Curvv EV coming in close proximity to the latter. Let's now look at how these cars compare against one another.
Tata Sierra EV dimensions vs Harrier EV, Curvv EV
The frunk and wheel sizes of the Sierra EV and Harrier EV differ based on variants
The Sierra EV is a significant 267mm shorter than the Harrier EV but 30mm longer than the Curvv EV. It’s not only 31mm wider than the Curvv EV but also a noticeable 113mm taller. Not just that, the Sierra EV is slightly taller than the Harrier EV, too. The Sierra EV has a wheelbase that’s 170mm longer than the Curvv’s but falls short of the Harrier’s by 11mm.
The luggage-carrying capacity of the Harrier EV is more than that of the Sierra EV, owing to its size. While we’re yet to measure it, Tata claims that the Sierra EV’s boot is similar in size to its combustion-powered namesake, where it’s 450 litres. This means that the Sierra EV’s boot is smaller than that of the Curvv EV by 50 litres. The frunk capacity of the Sierra EV and Harrier EV change based on the variant chosen, with the lower ones sporting more capacity. While the Sierra and Harrier can be had with 18- or 19-inch wheels, the Curvv EV is only offered with 18-inch rims.
Tata Sierra EV powertrain vs Harrier EV, Curvv EV
Sierra EV shares its dual-motor configuration, battery size and torque output with the Harrier EV
*Claimed acceleration figures of the top-spec variants.
Both the Sierra and Harrier come in single-motor rear-wheel drive (RWD) and dual-motor all-wheel drive (AWD) versions. The entry-level variant of the Sierra and Harrier have identical outputs, with the torque remaining identical between all variants of these two SUVs. However, the mid-spec and top-spec Sierra’s rear motors make less power than their Harrier counterparts. Meanwhile, the Curvv EV is only offered with one powertrain option.
Since it’s likely less heavy than the larger Harrier, the Sierra EV QWD (Tata’s parlance for AWD) manages to finish the sprint from 0-100kph half-a-second quicker. It’s also 2.8 seconds quicker to 100kph than the single-motor front-wheel drive Curvv EV. The claimed range of the base- and top-spec Sierra EV are comparable to those of the Harrier EV, but the former’s mid-spec 75kWh RWD version has a slight range advantage.
Meanwhile, the Curvv EV’s claimed range is 122km shy of the Sierra EV’s. Both the Sierra and Harrier with the 75kWh battery option can accept DC fast-charging, taking the battery from 20-80 percent in about the same time. When plugged into a 7.2kW AC charger though, the Curvv’s smaller battery can be charged from 10-100 percent in a little over 7 hours. The Sierra EV needs about 1-3 hours extra to do the same, and the Harrier EV take a similar amount of time.
Tata Sierra EV features vs Harrier EV, Curvv EV
Among the top-spec variants of all three, the Sierra EV is the most feature-packed car here
The Sierra EV gets a dedicated 12.3-inch infotainment screen for the front passenger, a JBL Black audio system with the most number of speakers, and a separate route planner meant currently for Android Auto users. It also comes with a new ‘AirConsole’ gaming feature, which syncs the user’s phone with the infotainment screen for playing games. Moreover, it’s only the Sierra EV that can be had with an augmented-reality head-up display (HUD).
The ‘Summon’ mode of the Sierra EV and Harrier EV allows the car to crawl out of parking spots using a key fob, while both models support Dolby Atmos and dual-zone climate control. Features like automatic headlamps & wipers, a driver’s seat with memory & welcome functions, 540-degree cameras, and hill-descent control are found on the Sierra EV as well as the Harrier EV. They also get 6 terrain modes: Normal, Grass/Snow, Mudruts/Gravel, Sand, Rock Crawl and Custom. However, the Harrier EV has 7 airbags and a larger primary touchscreen.
All three EVs come with four levels of regenerative braking, a gesture-activated tailgate, voice-activated panoramic sunroofs, and ventilated front seats. They also get Level 2 ADAS (Advanced Driver Assistance Systems) with adaptive cruise control and auto-emergency braking, plus vehicle-to-load (V2L) and vehicle-to-vehicle (V2V) functions. The Sierra EV has the most number of features here.
Prices of Tata Sierra EV vs Harrier EV, Curvv EV
While the top-spec Empowered X trim of the Curvv EV comes closest to the base-spec Sierra EV, the latter is still fairly well-loaded. Moving on to the Sierra EV and Harrier EV, their mid-spec Adventure trims are fairly matched in terms of pricing. At the top end, there’s Rs 3 lakh separating the fully loaded Tata Sierra EV from its equivalent Harrier EV counterpart. Some of the extra cash spent on the Sierra EV goes towards features that are exclusive to it – like the augmented-reality head-up display and dedicated screen for the front passenger. On the other hand, the price difference between the base Sierra EV and Curvv EV is Rs 1.8 lakh, with that gap widening to Rs 6.8 lakh at the top end.
