In the burgeoning electric midsize SUV segment, the Mahindra BE 6 and Tata Curvv EV are among the top contenders. While the range-topping BE 6 Pack Three has an advantage over the top-spec Curvv EV Empowered+ A 55 Dark in terms of battery size and ARAI range, the Tata is a whopping Rs 5.16 lakh cheaper than the Mahindra EV. Here, we see how close these EVs’ real-world range is to their ARAI figure and which one posts a higher battery efficiency in our rigorous and exhaustive mileage tests.
Mahindra BE 6 vs Tata Curvv EV Specifications and Price
he Mahindra BE 6 Pack Three offers more range and performance than the Curvv EV Empowered+ A 55 Dark, but at a premium price point. Here’s a quick specs breakdown:
| Parameter | Mahindra BE 6 Pack Three | Tata Curvv EV Empowered+ A 55 Dark |
|---|---|---|
| Battery Capacity | 79 kWh | 55 kWh |
| ARAI Range | 683 km | 502 km |
| Power | 286 hp | 167 hp |
| Torque | 380 Nm | 215 Nm |
| Drive Layout | RWD | FWD |
| Price (ex-showroom, incl. charger) | Rs 27.40 lakh | Rs 22.24 lakh |
The BE 6’s larger battery and rear-wheel-drive setup give it a clear edge in power delivery, making it feel more planted and responsive on the road. Meanwhile, the Curvv EV’s front-wheel-drive configuration keeps things nimble for city duties, and its lower price makes it more accessible for budget-conscious buyers.
The Real-World Range Test: Methodology
To put these EVs through their paces, we conducted exhaustive tests under controlled yet realistic conditions. Both vehicles started with fully charged batteries, maintaining manufacturer-recommended tire pressures. We ran fixed loops for city (mixed traffic, stops, and speeds up to 50 kmph) and highway (steady 80-100 kmph cruises) driving, with climate control set to 22°C on auto mode and typical electricals like infotainment in use. Range was extrapolated based on battery percentage consumed, ensuring a fair apples-to-apples comparison.Real-World Range Results: City, Highway, and CombinedThe Mahindra BE 6’s bigger 79 kWh pack proved its worth, delivering superior range across all scenarios despite the ARAI figures often being optimistic. The Tata Curvv EV, however, punched above its weight in efficiency, squeezing more kilometers from every kWh—ideal for those prioritizing running costs over outright distance.
| Test Condition | Mahindra BE 6 (km) | Tata Curvv EV (km) | Gap (BE 6 Advantage) |
|---|---|---|---|
| City | 438 | 371 | +67 km |
| Highway | 459 | 358 | +101 km |
| Combined | 449 | 365 | +84 km |
The BE 6 fell 234 km short of its ARAI claim in combined testing, while the Curvv EV was 137 km off—highlighting how lab conditions inflate expectations. On the highway, the Mahindra’s aerodynamic efficiency and torque-rich motor shone, comfortably outpacing the Tata at higher speeds. In the city, both handled urban chaos well, but the BE 6’s extra capacity meant fewer worries about mid-day top-ups.
Efficiency Showdown: km/kWh Breakdown
Efficiency is where the Tata Curvv EV steals the spotlight. Despite the Mahindra’s range lead, the Curvv EV achieved an impressive 6.64 km/kWh in combined testing—about 17% better than the BE 6’s 5.68 km/kWh. This edge stems from the Curvv’s lighter curb weight (around 1,550 kg vs. the BE 6’s 1,800 kg) and optimized FWD setup, which reduces energy loss.For context:
- Mahindra BE 6: At 5.68 km/kWh, the 79 kWh pack translates to that 449 km combined haul, but owners could see lower costs in high-mileage scenarios.
- Tata Curvv EV: 6.64 km/kWh from the 55 kWh battery means it’s thriftier per charge, potentially saving on electricity bills for daily commuters.
Beyond Range: Charging, Performance, and Verdict
Charging times add another layer. The BE 6 zips to 80% in 20 minutes on a 180 kW DC fast charger but takes 11.7 hours on a 7.2 kW AC wallbox. The Curvv EV is slower on DC (40 minutes to 70 kW) but quicker overall on AC (7.9 hours), suiting home overnight setups better.
Performance-wise, the BE 6’s 286 hp and 380 Nm make it a driver’s delight, hitting 0-100 kmph in about 6.7 seconds with effortless overtakes. The Curvv EV’s 167 hp feels adequate for most, clocking 8.6 seconds to 100 kmph, but lacks that punchy thrill.
In the end, if raw range is your priority for intercity jaunts, the Mahindra BE 6 edges out with 449 km combined—proving its ARAI promise isn’t all hype. But for efficiency-savvy urbanites, the Tata Curvv EV’s 365 km and superior km/kWh make it a smarter, more affordable pick at Rs 22.24 lakh. Both advance India’s EV game, but your drive style will decide the winner.
