MG Windsor EV: rent the battery or buy it outright?
MG will sell you a Windsor for ₹4.86 lakh less if you rent the battery at ₹3.99 a kilometre. We ran the break-even on MG's own figures, and the answer comes down to how far you drive, how long you keep the car and where the battery money would otherwise come from.
- Ex-showroom, battery bought
- ₹14.85 – 19.15 L
- BaaS up front
- ₹9.99 – 14.00 L
- Battery rental
- ₹3.99/km (38 kWh), ₹4.50/km (52.9 kWh)
- Break-even
- ≈1.22 lakh km (38 kWh), ≈1.14 lakh km (52.9 kWh)
- Claimed range
- 332 km (38 kWh), 449 km (52.9 kWh)

What is good
- BaaS cuts the up-front price by ₹4.86 lakh on the 38 kWh trims and ₹5.15 lakh on the Pro
- Bought outright, the battery has a lifetime warranty for the first owner, and charging runs at about ₹1 a km on MG's estimate
- The Pro adds the 52.9 kWh battery, 449 km claimed and 60 kW DC charging for ₹90,000 over the Essence
What is not
- With rental on top of charging, a BaaS Windsor costs roughly five times as much per km to run as one whose battery you own
- Some BaaS financiers bill a minimum of 1,500 km a month, and you cannot use your own bank
- Selling a BaaS car early means settling what is outstanding on the car and the battery first
What the showroom won't lead with
Every Windsor on MG's site carries two prices. Buy the Excite outright and it's ₹14,84,800 ex-showroom. Take it under Battery-as-a-Service and the sticker drops to ₹9,99,000, plus ₹3.99 for every kilometre you drive.
MG's own FAQ is candid about what that rental is: interest and principal. In other words, BaaS is a battery loan you repay by the kilometre instead of by the month, arranged only through MG's tie-up financiers. That isn't a bad thing. It just means the real question is how far you'll drive before the rental overtakes the discount.
The ladder, both ways
The BaaS discount is identical on every 38 kWh trim, ₹4,85,800, and identical on both Pro trims, ₹5,14,801. That is the price MG puts on each battery.
| Variant | Battery | Bought outright | BaaS up front | Rental per km |
|---|---|---|---|---|
| Excite | 38 kWh | ₹14.85 L | ₹9.99 L | ₹3.99 |
| Exclusiveour pick | 38 kWh | ₹16.15 L | ₹11.29 L | ₹3.99 |
| Essence | 38 kWh | ₹17.15 L | ₹12.29 L | ₹3.99 |
| Exclusive Pro | 52.9 kWh | ₹18.05 L | ₹12.90 L | ₹4.50 |
| Essence Pro | 52.9 kWh | ₹19.15 L | ₹14.00 L | ₹4.50 |
Ex-showroom, October 2026. BaaS prices and rental rates are from MG India's Windsor EV page, which lists the Pro BaaS prices as ₹12,89,999 and ₹13,99,999. Rental excludes charging. Ask us for the on-road number in your city.
Where the rental overtakes the discount
Divide the discount by the rate. On the 38 kWh car, ₹4,85,800 ÷ ₹3.99 is about 1.22 lakh km. On the Pro, ₹5,14,801 ÷ ₹4.50 is about 1.14 lakh km. Past that distance, renting has cost more than buying the battery would have.
How long that takes depends entirely on your running.
| Monthly running | 38 kWh rental a year | 38 kWh break-even | Pro rental a year | Pro break-even |
|---|---|---|---|---|
| 1,000 km | ₹47,880 | 10.1 years | ₹54,000 | 9.5 years |
| 1,500 kmour pick | ₹71,820 | 6.8 years | ₹81,000 | 6.4 years |
| 2,000 km | ₹95,760 | 5.1 years | ₹1,08,000 | 4.8 years |
| 2,500 km | ₹1,19,700 | 4.1 years | ₹1,35,000 | 3.8 years |
Simple break-even at MG's listed rates, before interest. Charging is extra on both routes.
The small print that moves the answer
Where the battery money comes from matters. Borrow the ₹4.86 lakh at 9% over five years and the interest is about ₹1.19 lakh, which pushes the 38 kWh break-even to roughly 1.5 lakh km. Pay cash and the simple figures above stand. Charging is on top either way; MG puts it at about ₹1 a km, so an owned battery runs for roughly a fifth of what a rented one costs per km.
MG's FAQ says some financiers set a minimum of 1,500 km a month. On the 38 kWh car that's ₹5,985 a month whether you drive it or not. MG says VidyutTech's plan bills only the kilometres you actually run, so ask for it by name if your running is low.
You can't bring your own bank: the package goes through MG's partners, currently Bajaj Finance, Hero FinCorp, VidyutTech and Ecofy. Sell early and you settle what's outstanding on car and battery first. MG's pages don't say what happens to the rental when the tenure ends, so get that in writing.
Bought outright, the battery carries MG's lifetime warranty for the first owner, which takes the sting out of the old worry about an ageing pack.
The smaller battery or the Pro
Every Windsor uses the same 136 PS, 200 Nm motor. The 38 kWh trims claim 332 km, so plan on about 250 km in daily use, with 45 kW DC charging. The Pro's 52.9 kWh pack claims 449 km and charges at 60 kW.
Bought outright, the Exclusive Pro is ₹1,90,000 over the Exclusive and ₹90,000 over the Essence, though it gives up the Essence's glass roof and ventilated seats. Under BaaS the bigger battery costs you twice: ₹1,60,999 more up front than the Exclusive, then 51 paise more per km for as long as you rent. At 1,500 km a month that's another ₹765 a month. If you're renting, stay with the smaller battery unless you genuinely need the range.
If you asked us in the showroom
If you can pay for the battery and drive 1,500 km a month or more, buy it. For mostly city running we'd take the Exclusive outright at ₹16,14,800: the 15.6-inch screen, 360-degree camera, powered driver seat and the 7.4 kW wall box. Regular out-of-town trips? The Exclusive Pro at ₹18,04,800.
BaaS makes sense if cash is tight, or your running is genuinely low and you can get a plan with no monthly minimum. Then the Exclusive at ₹11,29,000 plus ₹3.99 a km is a sensible way in. Get the tenure, the end-of-tenure terms and the exit charges in writing, then send us the quote and your monthly running. We'll check the sums before you sign.
