The recently launched Tata Sierra EV is positioned right below its larger sibling, the Harrier EV. However, there’s quite a lot of pricing overlap between the two Tata electric SUVs. To that end, we’ve compared the top-spec Sierra EV Empowered A 75 to the mid-spec Harrier EV Fearless+ 75 to find out which variant delivers better value on paper.
Explore full specs, features and a price breakdown in our Sierra EV vs Harrier EV comparison.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Dimensions
Harrier EV is longer and wider, but Sierra EV is taller and offers greater boot space
Expectedly, the Harrier EV is 267mm longer than the Sierra EV, but there’s only an 11mm difference between their wheelbases, suggesting that the smaller SUV doesn’t lose out on much interior space. While the Harrier EV is 81mm wider than the Sierra EV, the latter is 10mm taller. Wheel sizes are matched at 19 inches for both electric SUVs.
Interestingly, the Sierra EV offers 120 litres of additional boot space over the Harrier EV – it’s worth noting that both SUVs’ boot capacities are measured up to the roof, as opposed to the conventional method, which is up to the parcel tray. As for frunk capacity, the RWD Harrier EV offers the bigger one, but both EVs’ AWD versions are matched.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Battery and range
While Harrier EV offers more power, Sierra EV is quicker and claims higher range figures
Both the Sierra EV and Harrier EV get 75kWh battery packs, along with single-motor (RWD) and dual-motor (AWD) options. The Harrier EV edges ahead in terms of power, but the torque figures are identical. Despite the Sierra EV’s slightly lower output, its AWD variant is half a second quicker in the 0-100kph run compared to that of the Harrier EV – this is on account of the Sierra EV being smaller and lighter.
The Sierra EV is ahead in terms of MIDC-claimed range as well – by 2km in the AWD guise and by 38km in the RWD form.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Charging times
Both electric SUVs trade punches here
Despite both electric SUVs having identical battery capacities, the Harrier EV takes slightly longer to charge from 10 to 100 percent via a 7.2kW AC outlet. On the other hand, the Harrier EV has a marginally quicker 20-80 percent top-up time with a 120kW DC fast charger.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Exterior features
Harrier EV additionally offers side steps and a charging indicator in the front light bar
Coming to exterior features, the Sierra EV and Harrier EV are nearly matched. However, the Sierra EV does miss out on a charging indicator in the front light bar, with it being situated on the charging port. The Harrier EV additionally offers side steps, which make ingress and egress a tad easier.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Interior features
Sierra EV is the only Tata electric car to offer a triple-screen setup
Despite its lower positioning, the Sierra EV pulls a clear lead over the Harrier EV in terms of cabin equipment. Features such as a 12.3-inch passenger display and a head-up display are not offered even on the top-spec Harrier variant; even the sound system gets fewer speakers. In fact, the Sierra EV is currently the only electric Tata to come with a triple-screen setup.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Driving features
Sierra EV comes with extra terrain mode and adaptive cruise control
Both the top-spec Sierra EV and mid-spec Harrier EV are very similar in driving features. However, the Sierra EV gets an additional Custom terrain mode in the RWD version, as well as adaptive cruise control with stop-and-go functionality. The latter is much more convenient than the Harrier EV’s standard cruise control, as it can automatically adjust the speed based on proximity to nearby vehicles and even come to a standstill and set off by itself. AWD versions of both SUVs get additional terrain modes, too, namely Snow/Grass, Mud-Ruts, Sand, Rock Crawl and Custom.
Tata Sierra EV top-spec vs Harrier EV mid-spec: Safety features
Harrier EV has 7 airbags and a 5-star BNCAP rating; Sierra EV gets Level 2 ADAS and better camera setup
In the safety department, the Harrier EV holds some notable advantages, specifically a 5-star Bharat NCAP rating (the Sierra EV is yet to be tested but will likely perform well too), 7 airbags and driver drowsiness detection. The Sierra EV, though, trades punches with the Harrier EV thanks to safety features such as Level 2 ADAS and a 540-degree camera (360-degree with underfloor view).
Tata Sierra EV top-spec vs Harrier EV mid-spec: Prices and verdict
Sierra EV is up to Rs 70,000 cheaper
*Exclusive of home charger and installation, which costs Rs 49,000 extra.
The Sierra EV Empowered A 75 clearly emerges as the better option over the Harrier EV Fearless+ 75, as the smaller SUV offers considerably more comfort and convenience features, a larger boot, higher claimed range figures, similar powertrain outputs and charging speeds and greater performance – all while being Rs 40,000-70,000 more affordable.
Both the Sierra EV and Harrier EV get a lifetime battery warranty (15 years from the date of first registration) with unlimited kilometres, an 8-year/1,60,000km warranty for the electric motor(s) and a 3-year/1,25,000km vehicle warranty, so buyers can rest easy on this front.
