The Tata Sierra EV was recently launched as the manufacturer’s second all-electric offering with a dual-motor AWD choice. It is positioned between the Curvv EV and Harrier EV, the latter of which is also offered with an AWD option. So, between the Sierra EV and Harrier EV, whose top trim offers more features and better specifications? Let us find out.
Tata Sierra EV vs Harrier EV: Dimensions
Although smaller in size, the Sierra EV offers a larger boot and frunk
While the height and wheelbase of both the Sierra EV and Harrier EV are similar, the Harrier EV is longer and wider by a considerable margin. However, the Sierra EV offers a 120-litre larger boot space and a 20-litre larger frunk.
Notably, Tata has not revealed the official ground clearance figures of the Harrier EV, but it is likely to be similar to the Sierra EV's 205mm ground clearance.
Tata Sierra EV vs Harrier EV: Powertrain
Both get similar battery packs, but the Harrier EV offers more potent electric motors
*RWD = Rear-wheel-drive; AWD = All-wheel-drive
Top-spec trims of both the Sierra EV and the Harrier EV get identical 75kWh battery packs powering either a rear-axle-mounted (RWD) motor or dual electric motors (AWD). The Harrier EV RWD produces 29hp more than the Sierra EV RWD and has a higher claimed range.
With the AWD setup, the combined torque output of both SUVs is 504Nm, but their power outputs differ. The Harrier EV is the more powerful eSUV, its front and rear motors producing 18hp and 29 more than the Sierra EV, respectively. The claimed range of both Tata EVs is similar too.
Notably, the Sierra EV’s lower variants are offered with a 63kWh battery with an RWD motor, and the Harrier EV is also available with a smaller 65kWh battery with an RWD setup.
Tata Sierra EV vs Harrier EV: Exterior
Both eSUVs offer identical exterior features
Exterior features on both the top-spec Sierra EV and Harrier EV are identical. These include an all-LED lighting setup, 19-inch rims, powered outside rearview mirrors (ORVMS) and roof rails.
Tata Sierra EV vs Harrier EV: Interior and features
Sierra EV offers three screens and more speakers, but misses out on boss mode
One of the Tata Sierra EV’s USPs is a triple-screen setup, which is not even offered on the pricier Harrier EV. Compared to the Harrier EV, the Sierra EV also gets 2 more speakers and a coloured HUD.
The flagship Harrier EV, however, offers a larger touchscreen infotainment system and powered boss mode on the co-driver’s seat, which are not available on the Sierra EV. Other features are identical to both eSUVs.
Tata Sierra EV vs Harrier EV: Driving tech
Both electric SUVs are on par with each other in terms of driving tech
The Tata Sierra EV and Harrier EV share the same acti.ev+ platform, which is why they offer identical driving tech. These include 3 drive modes and up to 6 terrain modes (depending on the drivetrain).
Tata Sierra EV vs Harrier EV: Safety
Harrier EV gets an additional knee airbag and a digital IRVM
Over the Sierra EV, the top-spec Tata Harrier EV Empowered offer an additional knee airbag and a digital inside rearview mirror (IRVM). Other features, a 540-degree camera (with an under-bonnet view) and Level 2 ADAS, are identical on both EVs.
Tata Sierra EV vs Harrier EV: Price and verdict
Sierra EV is around Rs 3 lakh more affordable than the Harrier EV
The top-spec Tata Harrier EV’s Empowered trim is around Rs 3 lakh pricier than the Sierra EV’s fully loaded Empowered A trim. Although the Harrier EV is larger, the Sierra EV offers more boot space and a higher claimed range with both RWD and AWD. Unlike the Harrier EV, it gets features like a dedicated screen for the co-driver and more speakers, while getting the same driving tech as the Harrier EV. Although it misses out on boss mode, an additional knee airbag and a digital IRVM, a Rs 3 lakh difference makes the Sierra EV a better value-for-money proposition.
