In fact, Tata Motors continues to be the segment leader in the EV space. Mahindra is surely catching up with some pretty bold and impressive products. Hence, it becomes incredibly exciting for the customers since they have multiple options to choose the right EV for their individual requirements. For now, let us delve deep into the details of this thorough comparison here.

Tata Sierra EV vs Mahindra BE 6 – Specs Comparison
Let us now discuss what powers these potent EVs. The Tata Sierra EV is offered with two battery pack options – 63 kWh and 75 kWh, both featuring liquid-cooled and IP67-rated construction for enhanced durability and thermal management. The 63 kWh version develops 238 PS and 315 Nm of torque, while the larger 75 kWh battery is available in two configurations – a single-motor setup producing 209 PS and 315 Nm, and a dual-motor Quad Wheel Drive (QWD) version delivering an impressive 306 PS and 504 Nm. Tata claims a C75 real-world driving range of 440-460 km for the smaller battery and 510-530 km for the larger pack, while the QWD variant is expected to return around 480-500 km on a single charge. Such figures should provide ample confidence for buyers planning frequent long-distance journeys.
On the charging front, Tata Motors claims that high-capacity DC fast chargers (above 110 kW/261 A for the 63 kWh battery and above 120 kW/330 A for the 75 kWh unit) can replenish the battery from 20% to 80% in just 26 minutes. Using a 7.2 kW AC charger, a full 10-100% charge takes approximately 8.9 hours for the 63 kWh variant and 10.5 hours for the 75 kWh version. Performance is equally impressive, with the range-topping model capable of sprinting from 0-100 km/h in just 5.8 seconds in Boost mode. Enhancing overall ride comfort is Tata’s Ultra Glide suspension equipped with Frequency Dependent Damping, which promises a plush ride over rough surfaces while maintaining composure and stability at higher speeds.
In comparison, the Mahindra BE 6 is also available with two battery pack choices – 59 kWh and 79 kWh. Underpinned by Mahindra’s dedicated INGLO architecture, the electric SUV employs BYD’s advanced Blade Cell battery technology featuring LFP chemistry. The smaller battery variant produces 228 hp and 380 Nm of torque, while the larger pack boosts output to 281 hp with the same 380 Nm torque figure. Mahindra claims an impressive range of 535 km for the 59 kWh version and up to 682 km (550 km WLTP) for the 79 kWh model. Charging capabilities are equally noteworthy, with a 175 kW DC fast charger capable of taking the larger battery from 20% to 80% in just 20 minutes. Drivers can choose between Range, Everyday and Race drive modes, with the latter unlocking maximum performance and enabling a brisk 0-100 km/h run in just 6.7 seconds. Note that while most parameters are comparable, the Sierra EV is the only one with the option of an all-wheel-drive configuration.

My View
Now, choosing between these two compelling Indian electric EVs might be a challenge. Nevertheless, there are distinct pros and cons to each of these. If you are in the market for an imposing electric SUV with tons of new-age amenities, off-roading capabilities and want to save some bucks, the Tata Sierra EV makes better sense. However, if you want something that looks straight out of a sci-fi movie set, want all the bells and whistles but can do without the all-wheel-drive setup, the Mahindra BE 6 should be your pick. In any case, I would recommend our readers to experience the two in the flesh by visiting your nearest dealerships. That will help you make an informed decision. Also, it is hard to go wrong with any of these.

The arrival of the Tata Sierra EV is yet another sign of how rapidly the electric SUV segment around the Rs 20 lakh mark is evolving in India. What makes this comparison particularly interesting is that it pits two homegrown manufacturers against each other, both of whom are pushing the boundaries of EV technology, features and performance. While Tata Motors continues to enjoy a strong foothold in the electric passenger vehicle space, Mahindra has emerged as a serious challenger with its new-generation INGLO-based products. On paper, both the Sierra EV and BE 6 bring compelling strengths to the table, making the final choice far from straightforward. Ultimately, this is great news for buyers, who now have access to two highly capable electric SUVs tailored to different priorities and driving preferences.
