The Mahindra BE 6 SPORTEQ vs TATA SIERRA EV Comparison is one of the most interesting electric SUV comparisons in India right now. Mahindra BE 6 SPORTEQ has arrived with a wider variant lineup, three battery options and a new BaaS ownership plan, while the Tata Sierra.ev brings a more conventional SUV shape, two battery packs and even a dual-motor QWD option.

Both are positioned around the ₹19–27 lakh ex-showroom price bracket, so this is not simply a comparison of two electric SUVs—it is a question of which kind of EV ownership makes more sense for you.

Mahindra launched the BE 6 SPORTEQ on August 15, 2026, with deliveries scheduled from August 26. Tata launched the Sierra.ev on June 30, 2026, with deliveries beginning July 15.

So, BE 6 SPORTEQ vs Sierra EV—which one should you buy? Let’s break it down variant by variant.

Mahindra BE 6 SPORTEQ vs Tata Sierra EV: Price Comparison

Here is the most important part first.

Variant-wise ex-showroom price

Mahindra BE 6 SPORTEQ	Battery	Price	Tata Sierra.ev	Battery	Price
SPORTEQ One	59 kWh	₹19.45 lakh	Pure	63 kWh	₹18.79 lakh
SPORTEQ Two	59 kWh	₹20.95 lakh	Pure S	63 kWh	₹19.99 lakh
SPORTEQ Three	59 kWh	₹21.95 lakh	Adventure	63 kWh	₹20.99 lakh
SPORTEQ Three	70 kWh	₹22.95 lakh	Adventure	75 kWh	₹22.19 lakh
SPORTEQ Three+	70 kWh	₹23.95 lakh	Empowered	63 kWh	₹22.79 lakh
SPORTEQ Three+	79 kWh	₹24.95 lakh	Empowered	75 kWh	₹23.79 lakh
SPORTEQ Four	79 kWh	₹26.95 lakh	Empowered A	75 kWh	₹24.79 lakh
Launch Edition	79 kWh	₹26.95 lakh	Empowered A QWD	75 kWh	₹25.99 lakh

Mahindra’s official launch prices also include the Formula E variants: FE at ₹24.45 lakh and FE Four at ₹26.95 lakh. The SPORTEQ range has eight core variants and three battery sizes—59, 70 and 79 kWh.

Tata’s Sierra.ev is available with 63 kWh and 75 kWh batteries, while the 75 kWh Empowered A can also be specified with dual-motor QWD at ₹25.99 lakh. The prices above are introductory ex-showroom prices and exclude the optional 7.2 kW AC charger.

The first interesting result

The Sierra EV is cheaper at almost every comparable entry point.

For example:

• Sierra Pure: ₹18.79 lakh
• BE 6 SPORTEQ One: ₹19.45 lakh

That’s a ₹66,000 difference in Tata’s favour.

At the next level:

• Sierra Pure S: ₹19.99 lakh
• BE 6 SPORTEQ Two: ₹20.95 lakh

Here, the Sierra is cheaper by ₹96,000.

However, the comparison becomes more interesting once you start looking at battery size and performance rather than just variant names.

Battery and Range: Sierra EV Has the Edge on Paper

The BE 6 SPORTEQ gets three battery choices:

• 59 kWh — 548 km MIDC
• 70 kWh — 651 km MIDC
• 79 kWh — 683 km MIDC

The Tata Sierra.ev gets:

• 63 kWh — 565 km MIDC
• 75 kWh — 665 km MIDC
• 75 kWh QWD — 624 km MIDC

These figures come from the manufacturers’ specifications and the launch information supplied in the respective specification sheets.

On paper, Tata has a slight advantage in the smaller battery configuration, while Mahindra’s 79 kWh battery offers the highest claimed range of the two at 683 km.

But there is an important catch.

The Sierra’s 75 kWh RWD claims 665 km, while its AWD/QWD version drops to 624 km because of the additional motor and hardware. That’s completely normal for an AWD EV.

So if your priority is maximum range, the BE 6 SPORTEQ 79 kWh is particularly attractive.

If you want a long-range SUV but don’t need AWD, the Sierra 75 RWD is also an excellent proposition.

Performance: This Is Where the BE 6 SPORTEQ Gets Serious

The BE 6 has always been positioned as the sportier, more driver-focused EV, and SPORTEQ continues that philosophy.

According to the specifications you provided, its motor outputs are:

• 59 kWh: 170 kW
• 70 kWh: 180 kW
• 79 kWh: 210 kW
• Maximum torque: 380 Nm
• RWD

The Sierra.ev takes a slightly different approach.

Its 63 kWh RWD version produces 175 kW and 315 Nm, while the 75 kWh RWD makes 154 kW and 315 Nm. The top 75 kWh QWD version uses two motors, producing a combined 504 Nm.

And that makes the comparison fascinating.

If you want outright performance:

BE 6 SPORTEQ 79 kWh is the more interesting RWD performance option.

If you want traction and all-weather capability:

Sierra.ev 75 kWh QWD is the clear choice.

The Sierra QWD also gets six terrain modes, including Normal, Snow/Grass, Mud-Gravel, Sand, Rock Crawl and Custom.

Charging: Both Are Road-Trip Friendly

The BE 6 SPORTEQ can charge from 20–80% in around 20 minutes with the appropriate DC charger, according to the specification sheet you shared.

The Sierra.ev takes around 26 minutes for 20–80% using a 120 kW DC fast charger. Tata also claims it can add around 263 km of range in 15 minutes.

So Mahindra has the advantage in the headline charging time.

But in real life, charging infrastructure will matter more than a six-minute difference. If you’re buying either car primarily for long-distance travel, check fast-charger availability on your regular routes before making the final decision.

Dimensions and Practicality: Sierra Is the More Conventional Family SUV

The BE 6 measures:

4,371 mm × 1,907 mm × 1,627 mm

with a 2,775 mm wheelbase.

The Sierra.ev measures:

4,340 mm × 1,841 mm × 1,750 mm

with a 2,730 mm wheelbase.

The Mahindra is therefore longer and wider, while the Sierra is noticeably taller.

Tata also offers a 622-litre boot, plus a 55-litre frunk in the RWD versions according to the supplied specification sheet.

This gives the Sierra a more traditional family-SUV personality.

The BE 6, meanwhile, has a much more dramatic coupe-SUV profile.

And that brings us to one of the biggest differences between these two cars.

BE 6 SPORTEQ vs Sierra EV: Which One Feels More Special?

Mahindra BE 6 SPORTEQ

The Mahindra is the choice for someone who wants the EV to feel futuristic and different.

The SPORTEQ brings a three-screen cockpit from the TWO variant onwards, along with Mahindra’s new TEQ technology suite. It includes features such as TEQ_Talk with Google Gemini, personalised profiles, digital car key functionality, entertainment features and new drive-related functions.

The Launch Edition gets a Graphite Storm exterior and Racing Tan interior, while the Formula E Freedom Edition gets its own motorsport-inspired treatment.

Tata Sierra.ev

The Sierra goes for a more premium lounge-like approach.

It also gets a triple-screen dashboard, panoramic sunroof, JBL audio with Dolby Atmos, ventilated and powered seats, Boss Mode, Level 2 ADAS and a large boot.

In simple terms:

BE 6 = sporty, futuristic and driver-focused.

Sierra = premium, practical and family-focused.

What About Mahindra’s BaaS Price?

This is something buyers should understand before getting excited about the ₹11.45 lakh starting price.

The BE 6 SPORTEQ One is available at ₹11.45 lakh under BaaS, but the battery is charged separately at ₹3.75 per km. SPORTEQ Two starts at ₹12.95 lakh under the same arrangement.

So don’t compare:

₹11.45 lakh BE 6 vs ₹18.79 lakh Sierra

as though both are conventional purchase prices.

They aren’t.

The regular battery-included starting price of the BE 6 SPORTEQ is ₹19.45 lakh, making the Sierra Pure only ₹66,000 cheaper.

For a high-mileage owner, the BaaS model needs to be evaluated based on your expected annual kilometres and ownership period.

Expert Verdict: Which One Should You Buy?

Buy the Mahindra BE 6 SPORTEQ if…

You should choose the BE 6 if you:

• want a sporty driving experience
• love futuristic styling
• want the largest 79 kWh battery
• want up to 683 km claimed MIDC range
• prefer strong RWD performance
• like technology and connected features
• want a more distinctive-looking SUV
• are interested in the BaaS ownership option

My pick: SPORTEQ Three+ 79 kWh at ₹24.95 lakh looks like one of the sweet spots in the range. You get the large battery without jumping all the way to the ₹26.95-lakh Four/Launch Edition.

Buy the Tata Sierra.ev if…

The Sierra makes more sense if you:

• want a practical family SUV
• prefer a conventional SUV driving position
• want the lowest entry price
• want a large boot
• want the option of AWD/QWD
• regularly drive on rough or slippery terrain
• want a comfortable long-distance EV
• value Tata’s familiar SUV character

My pick: The 75 kWh Adventure at ₹22.19 lakh is particularly interesting because it combines the larger battery with a relatively sensible price.

If money isn’t a major concern and you genuinely need AWD, the 75 kWh Empowered A QWD at ₹25.99 lakh is the more capable choice.

For someone who wants maximum range and performance: BE 6 SPORTEQ 79 kWh.

For someone who wants practicality and AWD: Sierra.ev 75 kWh QWD.
