MG Windsor EV Crosses 75,000 Sales: How a Battery-Rental Idea Reshaped India’s EV Market

The MG Windsor has become India’s best-selling electric vehicle, crossing 75,000 cumulative units sold in under two years since its October 2024 launch — a milestone that matters less for the round number itself and more for the ownership model behind it. The Windsor’s real legacy is popularizing Battery-as-a-Service (BaaS) in the Indian passenger vehicle market, a pricing structure that let buyers pay a lower upfront cost for the car and a separate per-kilometre charge for battery usage, rather than bundling the most expensive EV component into the sticker price from day one.

For anyone tracking India’s EV adoption curve or planning campaigns in the electric mobility space, the Windsor’s milestone is a useful case study in how a single pricing innovation, more than any single spec sheet advantage, changed the competitive playbook for an entire vehicle category.

The Sales Numbers, in Detail

According to detailed monthly sales tracking, the Windsor sold 75,498 units between October 2024 and June 2026. It opened with 3,116 units in its first month and has sustained demand well past the typical launch-phase enthusiasm window, closing June 2026 with 4,056 units — a 6.8% year-on-year increase over June 2025 and nearly double its May 2026 volume. Its strongest single month to date came in September 2025, at 4,741 units, and the second half of 2025 was a particularly consistent stretch, with the Windsor crossing the 4,000-unit mark in five consecutive months from July through November.

That growth curve, though, hasn’t been perfectly linear. In the first half of CY2026, the Windsor sold 19,080 units total, but the month-to-month pattern tells a more nuanced story than the headline milestone suggests: January and February were comparatively soft, March saw a sharp recovery, May dipped again, and June rebounded strongly. Data shows that kind of volatility is fairly typical for EVs still building out charging infrastructure confidence among buyers outside metro markets, and it’s worth flagging for anyone using the Windsor as a benchmark for EV demand forecasting — a single strong or weak month in isolation doesn’t reliably predict the next one.

What Actually Made the Windsor Work

MG’s core innovation with the Windsor was decoupling the battery cost from the vehicle’s purchase price. Under the BaaS program, buyers can acquire the Windsor for an entry price of Rs 9.99 lakh plus a per-kilometre battery rental charge, rather than paying the full outright price of Rs 14.70-19.00 lakh (ex-showroom) upfront. For a market where EV adoption has consistently been held back by sticker-price anxiety — even among buyers who understand the long-run running-cost savings — removing the single largest cost component from the initial purchase decision addressed the actual psychological barrier rather than just the economic one.

The Windsor is offered in three variants across two battery options: a 38 kWh pack rated for up to 331-332 km of range, and a higher Pro-spec 52.9 kWh pack rated up to 449 km. Power output sits at 100kW (136ps) with 200Nm of torque. On the inside, MG leaned into a “lounge on wheels” positioning rather than competing on SUV ruggedness — reclining rear seats that tilt back 135 degrees, a large 15.6-inch touchscreen, a panoramic glass roof and ventilated front seats, all aimed at buyers prioritizing cabin comfort over outright road presence.

An Idea the Rest of the Industry Has Now Copied

The clearest evidence that MG’s BaaS bet paid off isn’t the Windsor’s own sales figures — it’s how many competitors have since adopted the same structure. Tata Motors introduced Battery-as-a-Service on the Punch EV and later extended it to the Tiago EV. Maruti Suzuki brought the same model to the e Vitara. And Hyundai, the most recent entrant to follow this path, has now applied it to the Creta Electric. In under two years, an approach that started as MG’s specific differentiator has become something close to an industry-standard financing option across multiple manufacturers and price points.

That pattern is worth sitting with for a moment: it’s relatively rare for a single model’s go-to-market pricing structure — as opposed to a design language, a feature, or a powertrain choice — to get replicated this broadly across an entire vehicle category within two years. It suggests MG identified something closer to a structural barrier in Indian EV adoption than a Windsor-specific marketing gimmick, and rival automakers have concluded the same thing based on how quickly they’ve followed.

Reading the Broader EV Adoption Signal

According to JSW MG Motor India, the company posted 13% year-on-year growth in overall sales across H1 CY2026 compared to H1 CY2025, with the Windsor as the clear driver of that momentum. MD Anurag Mehrotra framed the milestone around the Windsor’s reach across both metro and emerging markets — a detail worth noting given that EV adoption outside India’s largest cities has historically lagged well behind urban centers, constrained by charging infrastructure gaps and range anxiety concerns that are harder to address with public charging investment alone in smaller towns.

If the Windsor is genuinely gaining traction beyond metro buyers, as MG’s own commentary suggests, that’s a more meaningful signal for the broader EV market’s health than another strong month of big-city sales would be — it points toward EV consideration finally extending into segments of the buyer base that have been the slowest to convert from internal combustion vehicles, which is the harder and more consequential shift for the category’s long-term trajectory than incremental gains among buyers who were already EV-curious in Bengaluru or Delhi.

What This Means for the EV Segment Going Forward

For anyone marketing or selling in the EV space, the Windsor’s trajectory offers two clear takeaways. First, pricing structure innovation can move category-wide adoption more effectively than incremental range or feature improvements — buyers weren’t waiting for a better battery, they were waiting for a way to afford the one that already existed. Second, the BaaS model’s rapid adoption by Tata, Maruti and Hyundai means it’s no longer a genuine differentiator on its own; brands competing in this space now need a next-generation hook beyond “we also offer battery rental” to stand out, since that specific advantage has effectively become table stakes across the segment within the same two-year window the Windsor took to hit its own milestone.

What Comes Next for the Windsor’s Growth Story

The more interesting question from here isn’t whether the Windsor can sustain 4,000-plus units a month — it’s already demonstrated it can do that across five consecutive months once, and again in June 2026 — but whether MG can convert its BaaS-driven volume into durable brand loyalty as rivals offer functionally similar financing on their own EVs. Once every major manufacturer offers some version of battery rental, buyers choosing between a Windsor and a Creta Electric or e Vitara will increasingly decide based on cabin space, charging network access and after-sales service network depth rather than the financing structure itself, since that variable will have stopped differentiating the options.

That shift puts pressure on JSW MG Motor India to build out service infrastructure and charging partnerships at the same pace it scaled Windsor sales, particularly in the emerging, non-metro markets the company has specifically highlighted as a growth area. In our experience tracking EV adoption patterns across manufacturers, the brands that win the second phase of category growth — after the initial pricing-innovation phase plays out — tend to be the ones that quietly built service and charging infrastructure ahead of demand, rather than those still catching up once volume has already arrived. Whether MG has done that groundwork in the markets beyond its existing metro strongholds will likely determine whether the Windsor’s next 75,000 units come as easily as the first.
