The Tata Sierra EV is the most recent all-electric offering in the manufacturer’s lineup, which is positioned between the Curvv EV and Harrier EV. The new Sierra EV is priced from Rs 18.79 lakh to Rs 25.99 lakh, while the Curvv EV’s prices range from Rs 16.99 lakh to Rs 19.19 lakh. So, if you have a budget of around Rs 20 lakh, should you go for the top-spec Curvv EV Empowered X or the similarly priced one-above-base Sierra EV Pure S variant? Let’s find out.
Tata Sierra EV Pure S vs Curvv EV Empowered X: Dimensions
Sierra EV has larger dimensions and offers additional boot space
Both Tata EVs are offered with 5 seats, but the Sierra EV is larger than the Curvv EV in all respects. While the differences in height and width won’t matter much in the real world, the Sierra EV’s 113mm-taller height and 170mm-longer wheelbase are expected to translate into better cabin space than the Curvv EV. The Sierra EV also offers 19mm higher ground clearance, a 122-litre larger boot, and 40+ litres of additional frunk space, making it more practical than the Curvv EV.
Tata Sierra EV Pure S vs Curvv EV Empowered X: Powertrain
Sierra EV Pure S packs a larger battery and a more potent electric motor
*RWD = Rear wheel drive, FWD = Front wheel drive
The Sierra EV’s Pure S variant has a slightly larger battery pack, enabling a whopping 163km higher claimed range compared to the Curvv EV’s Empowered X variant. Respective variants of both Tata EVs are offered with a single-motor setup, but with different layouts. Notably, the top-spec Sierra EV is also available with a dual-motor AWD system with a larger 75kWh battery, but at a much higher price point. The Curvv EV, however, is only offered in a FWD configuration with a 55kWh battery across its lineup.
Along with a larger battery, the Sierra EV 63kWh version is also offered with a more powerful motor, producing 44hp and 100Nm more than the Curvv EV.
Tata Sierra EV Pure S vs Curvv EV Empowered X: Exterior
Both EV variants offer similar exterior features
Except for the missing roof rails on the Curvv EV, the exterior features on both the Tata Sierra EV Pure S and Curvv EV Empowered S are the same. Both EVs get all-LED lighting, flush-type door handles, 18-inch alloys and a shark-fin antenna.
Tata Sierra EV Pure S vs Curvv EV Empowered X: Interior, features
A powered driver’s seat and a powered tailgate are not offered with the Sierra EV Pure S
*Curvv EV’s sound system includes JBL-sourced 8 speakers and a subwoofer
The top-spec Curvv EV Empowered X gets a few additional features over the lower-spec Sierra EV Pure S, including a powered driver’s seat with ventilation function, a powered tailgate, a subwoofer and leatherette seat upholstery. The Curvv EV also gets a full-blown air purifier, while the Sierra EV’s one-over-base Pure S trim offers only a PM2.5 air filter.
Other features like the 10.25-inch and 12.3-inch screens, a panoramic sunroof, a wireless phone charger, V2L and V2V charging support and auto climate control with rear vents are common to both EVs.
Tata Sierra EV Pure S vs Curvv EV Empowered X: Driving tech
The Curvv EV offers adaptive cruise control over the Sierra EV’s Pure S variant
Both EV variants are offered with the same drive modes and paddle shifters to control the battery regeneration level. The difference, however, is that the top-spec Curvv EV gets adaptive cruise control, while the Sierra EV Pure S gets standard cruise control.
Tata Sierra EV Pure S vs Curvv EV Empowered X: Safety features
Curvv EV gets an ADAS suite and a 360-degree camera over Sierra EV Pure S
Safety features such as 6 airbags, front and rear parking sensors, a tyre pressure monitoring system (TPMS) and disc brakes on all wheels are common to both EVs. The top-spec Curvv EV Empowered X, however, goes a step further and offers a 360-degree camera, an auto-dimming inside rearview mirror, and a Level-2 advanced driver assistance system (ADAS).
Tata Sierra EV Pure S vs Curvv EV Empowered X: Price, verdict
Sierra EV Pure S offers more claimed range but misses out on some premium features
The lower-spec Tata Sierra EV is Rs 80,000 pricier than the top-spec Curvv EV Empowered X. However, at the higher price, the Sierra EV Pure S offers a larger battery pack with a higher claimed range. The Tata Sierra EV is also larger, which translates to better cabin space. Although it misses out on premium features like a powered driver’s seat, a powered tailgate, Level-2 ADAS and a 360-degree camera, it offers a decent feature suite. All of this makes the Sierra EV Pure S a better offering compared to the Curvv EV Empowered X.
