Mahindra XEV 9S vs MG Hector Tomahawk EV: Which 7-Seater Electric SUV Should You Buy?

The quick answer: Choose the MG Hector Tomahawk EV if you want the most space for the least money. It's the physically bigger SUV, starts around ₹19.5 lakh, offers a 5-seater option, and can power your home during a power cut using Vehicle-to-Home (V2H). Choose the Mahindra XEV 9S if range, charging and features matter more. It offers three battery sizes, up to 679 km of claimed range, double the Tomahawk's peak DC charging rating, and more power. If your budget stops near ₹23–24 lakh, the MG is the value buy. If you can stretch, the XEV 9S is the more complete EV.

Specs at a Glance

Space and Practicality: The MG Is the Bigger Car

Here's what most people miss: the XEV 9S looks bigger, but it isn't. The Tomahawk is 4,745 mm long, 1,850 mm wide and 1,770 mm tall, with a 2,810 mm wheelbase. That makes it larger than the XEV 9S in every dimension except width.

That longer wheelbase isn't just a spec-sheet win. The Tomahawk's extra 48 mm between the axles translates into noticeably more room in the second and third rows.

Boot space:

• Tomahawk 7-seater: 192 litres with all three rows up, or 528 litres with the third row folded
• Tomahawk 5-seater: a 610-litre boot
• XEV 9S: little boot space with the third row in use, though its 150-litre front trunk holds small bags

Third-row reality check: The XEV 9S's last row suits shorter adults or kids, who'll sit with their knees raised. The 6-seater version helps. The gap between its middle captain seats makes the third row much easier to reach and gives those passengers more room to stretch out.

Range and Charging: Mahindra Pulls Ahead

This is where the two cars differ most.

Even the smallest XEV 9S battery out-claims the MG. The 59 kWh base model is rated for 521 km, which is more than the Tomahawk manages with its bigger 69.2 kWh pack.

Why? According to Autocar India, the XEV 9S sits lower and cuts through the air more cleanly. The Tomahawk is bigger, heavier and more upright, and both weight and shape hurt efficiency, especially at highway speeds.

What you'll actually get

Claimed figures come from a lab test. Real-world numbers are more useful:

• Tomahawk EV: On a spirited 192 km highway run, Autocar India recorded 4.85 km/kWh. That works out to about 336 km of real-world range.
• XEV 9S: According to ZigWheels, its battery options manage around 400–500 km in real-world driving.

Rule of thumb: those real-world figures land at roughly 65–75% of the claimed MIDC range. Use this as a planning estimate, not a promise. Highway speed, AC use and how much you're carrying all change the number.

Charging speed

• XEV 9S: 7.2 kW and 11.2 kW AC wallbox options, 13A portable charging, and DC fast charging at up to 180 kW
• Tomahawk: DC fast charging at up to 90 kW, with a claimed 30–80% top-up in 35 minutes. A full 10–100% charge on the 7.4 kW home charger takes around 12.5 hours.

One thing competitors rarely mention: a car's peak charging rating only helps if the charger can deliver that much power. Before paying extra for charging headroom, check what the chargers on your regular routes actually put out.

Performance and Ride

The XEV 9S is the enthusiast's pick. Every version drives the rear wheels through a single rear-mounted motor. Reviewers say it's still easy to drive, with sharp throttle response that never feels overwhelming. Even newer drivers settle in quickly.

The trade-off is the ride. The suspension feels soft and a bit bouncy. It absorbs bad roads well, but it's slow to settle afterward.

The Tomahawk isn't sluggish either. It makes 201 bhp and 310 Nm and hits 100 km/h in 8.2 seconds. Unlike the plug-in hybrid version, the EV is front-wheel drive only.

It also has a clear edge on rough roads. Its ground clearance is 230 mm, measured to the battery, which is the best in its class.

V2L and V2H: The MG's Power-Cut Advantage

Picture this. It's a humid summer evening, the power's gone, and your inverter dies after two hours. Meanwhile, a 69.2 kWh battery sits in your driveway doing nothing.

That's the problem MG is solving. The Tomahawk EV supports three reverse-charging modes: Vehicle-to-Load (V2L), Vehicle-to-Vehicle (V2V) and Vehicle-to-Home (V2H).

What each mode does

MG claims the Tomahawk EV is the first car in India to offer Vehicle-to-Home.

V2L in real life:

• The Tomahawk has a Camp Mode that sets up the cabin for outdoor use and powers compatible gadgets through V2L.
• At one MG event, a single Tomahawk EV powered the whole venue through its charging port.

Features and Safety

Both cabins feel premium. They just get there differently.

Mahindra XEV 9S highlights:

• A three-screen dashboard and cooled second-row seats
• Depending on the variant, a 16-speaker Harman Kardon system, ventilated front and second-row seats, an AR head-up display, a 360-degree camera and Level 2 ADAS
• 6 or 7 airbags depending on variant, disc brakes on all four wheels and an electronic parking brake
• A 150-litre frunk

MG Hector Tomahawk EV highlights:

• A 15.6-inch touchscreen, the biggest in its segment, and a 10-speaker Infinity sound system, though no Dolby Atmos
• A powered tailgate, panoramic sunroof, ventilated front seats, wireless charging, rear window sunshades, and V2V, V2L and V2H charging support
• A Pro Pet mode that keeps the AC running while the car is locked
• Six airbags, Level 2 ADAS, a 360-degree camera, ESC, TPMS and ABS with EBD

Price, BaaS and Real Running Costs

At the entry level, the Tomahawk costs over ₹1 lakh less than the cheapest XEV 9S. Further up the range, the XEV 9S climbs toward ₹30 lakh. At that end it adds bigger batteries, faster charging, more range and more features.

Battery-as-a-Service, decoded

Both brands let you pay less upfront and finance the battery separately:

• MG: ₹13.99 lakh upfront, plus ₹4.90 per km for the battery as you drive
• Mahindra: ₹12.65 lakh upfront, plus an effective battery cost of ₹3.75 per km

Don't compare those per-km figures side by side without context:

• Mahindra's ₹3.75/km is based on assumptions. It assumes a starting battery EMI of ₹6,975 and 60 km of driving a day.
• Mahindra's BaaS is a loan, not a rental. Mahindra describes it as a dual-loan finance product, with one loan for the car and another for the battery.
• Your real per-km cost can be higher. It depends on the battery loan you're approved for, and ₹3.75/km is the minimum.
• Taxes are charged on the full price. Under Mahindra's BaaS, road tax, insurance and other statutory charges are still calculated on the vehicle's full value, battery included.

Quick math: if you drive 1,500 km a month, MG's battery charge comes to ₹7,350 (1,500 × ₹4.90). Ask MG whether there's a minimum monthly charge and what happens when the plan ends. Ask Mahindra what your actual battery EMI would be.

Home charging

MG adds a real sweetener here. Every Tomahawk EV comes with a 7.4 kW AC home charger, and installation is included as standard. Mahindra's quoted XEV 9S prices don't include a charger, so add that to your budget. The V2H unit is a separate purchase from this standard charger, so budget for both if you want home backup.

Common Mistakes Buyers Make

• Trusting the claimed range. Plan your trips around real-world figures instead.
• Buying seven seats "just in case." If your third row gets used twice a year, the Tomahawk 5-seater's 610-litre boot may serve you better every single day.
• Paying for charging speed you can't use. Check what the chargers on your usual routes actually deliver.
• Assuming BaaS is automatically cheaper. Add up the vehicle EMI, battery EMI, insurance and electricity over the years you plan to own the car.
• Skipping a bad-road test drive. The XEV 9S's soft suspension divides opinion, so drive both cars over broken tarmac before you decide.

Which One Should You Buy?

Final Takeaway

These two SUVs answer different questions.

The MG Hector Tomahawk EV asks, "How much car can I get for my money?" The answer is a lot: more space, more ground clearance, a home charger in the box, and a battery that can keep your lights on when the power goes out.

The Mahindra XEV 9S asks, "How good can a family EV be?" It answers with more range, higher peak charging speed, more power and a richer feature list.

My advice? Settle your budget first, then decide how much V2H matters where you live. After that, test-drive both on the roads you actually use, with the people you'll actually carry.
