Tata Motors has launched Sierra EV in the Indian market after a long wait. Available at a starting price of just ₹ 18.79 lakh (ex-showroom), this SUV comes with 63 kWh and 75 kWh battery options. One thing was most discussed at the time of launch – why is the power output of the 75 kWh RWD variant less than the 63 kWh RWD?

The 63 kWh model produces 238 PS (175 kW), while the 75 kWh RWD produces only 209 PS (154 kW). This is a difference of 29 PS (about 12%), while the 75 kWh variant is also costlier and has a longer range. Tata has now given an official statement regarding this.

Why is power reduced in bigger packs?

According to Tata Motors, this is not a mistake but an intentional engineering decision. Both batteries are packed in the same volume. The 75 kWh battery uses high-capacity cells and Cell-to-Pack (C2P) architecture, achieving excellent packaging efficiency of 141 Wh/kg and 8.9 km/kWh energy efficiency.

This brings the ARAI range to 665 km (99 km more than 63 kWh). However, this resulted in a slight reduction in operating voltage, resulting in reduced peak power. The company says that the peak torque of 315 Nm is the same in both the RWD variants, so there will be no significant difference in daily driving and city-highway performance. 75 kWh is range-focused, while 63 kWh is performance-oriented.

Design and interior

Sierra EV comes with an attractive design like the ICE model. Its highlights are closed-off grille, end-to-end LED DRL, LED taillights, flush door handles, 19-inch alloy wheels with aero inserts and a large panoramic sunroof (1525mm x 925mm). The 2730 mm wheelbase and 622 liters of boot space add to the practicality.

The cabin has a triple screen setup (two 12.3-inch + 10.25-inch). Light colours, spacious feel, ventilated and memory seats, extendable under-thigh support, rear blinds and leatherette upholstery provide a premium experience.

Features and safety

12-speaker JBL sound system (Dolby Atmos), wireless Android Auto/Apple CarPlay, EV Route Planner, DrivePay (UPI), AirConsole Gaming, iRA.ev connectivity, 540° camera and gesture-controlled powered tailgate are the big features.

For safety, it has features like L2+ ADAS, 6 airbags, strong structure and V2L/V2V. 6 terrain modes and crawl control are also provided for off-road.

Battery, Motor and Range

The 63 kWh battery gives 565 km ARAI range, while the 75 kWh will give 665 km range. Both RWD have 315 Nm torque. AWD option is also available in 75 kWh. Fast charging can add 263 km range in 15 minutes. The speed of 0-100 km/h is completed in 5.8 seconds. Built on the Acti.ev platform, this SUV offers a great combination of performance and range.
