India's electric vehicle market has hit a turning point. For years the question was whether buyers would trust battery-powered cars and scooters. Now the question is whether factories can build them fast enough. Four of the country's biggest EV players — Tata Motors, Mahindra, Ather Energy and Bajaj Auto — are all reporting that customer orders exceed what their production lines can deliver. The shortage spans both passenger cars and two-wheelers, making this a sector-wide issue rather than a problem for any single company.
The numbers tell a clear story. Mahindra Electric Automobile has reached a structural capacity of about 8,000 electric vehicles per month, but demand stands at 10,000 to 11,000 units. Tata Motors Passenger Vehicles says EV demand is nearly three times available supply. Ather Energy reports losing 18,000 to 20,000 potential retail sales each month due to production limits. Bajaj Auto built only 40,000 Chetak scooters in September against a target of 60,000. All four companies confirm they are supply-constrained, though the sources stop short of saying every plant is running at absolute maximum capacity.
What the executives are saying
Mahindra's managing director R Velusamy has been direct about the gap. He stated the company retailed over 8,000 vehicles in recent months but demand is heading toward 10,000 to 11,000 units monthly. Velusamy added that without supply constraints, Mahindra could sell another 2,000 to 3,000 vehicles each month. He expects supply constraints to ease by the third quarter of FY27 (October to December 2026), with additional manufacturing capacity arriving from the fourth quarter.
Tata Motors Passenger Vehicles managing director Shailesh Chandra gave the most striking ratio: EV demand is nearly three times supply. This implies Tata can deliver only about a third of the EVs customers want. Chandra indicated supply should catch up within two to three months, though no specific capacity figure or expansion timeline has been published.
Ather Energy co-founder and CEO Tarun Mehta quantified the shortfall on an earnings call, saying the company has roughly 20,000 units per month of unrealised retail demand. Bajaj Auto joint managing director Rakesh Sharma linked the company's expansion plans to gaining market share and reaching new customers, suggesting Bajaj sees supply — not demand — as the limiting factor.
Capacity expansion plans compared
Each company has announced plans to close the gap, but timelines and scales differ. Mahindra aims to raise monthly electric-SUV capacity from 8,000 to 12,000 units by the end of the current financial year, a 50 percent increase. Extra capacity is expected from Q4 FY27 (January to March 2027). Even at 12,000 units, the company would only just cover the top end of current demand.
Ather Energy has the most aggressive percentage expansion. One plan shows annual capacity rising from 420,000 to 920,000 units through a new AURIC facility in Maharashtra. A more detailed plant-level plan targets 495,000 units at Hosur (up from 420,000) and 650,000 units at Chhatrapati Sambhajinagar (up from 500,000), totalling about 1.14 million units annually by Q2 FY28 (July to September 2027). Ather plans to invest Rs 122 crore to add 225,000 units of annual capacity across these two existing plants.
Bajaj Auto plans to lift Chetak production from roughly 62,000 to 80,000 units per month by Q4 FY27, a 29 percent increase. Total annual capacity is expected to grow from 625,000 to about 775,000 units over the next six to nine months. The company's September shortfall — 20,000 units below plan — highlights why this expansion matters.
Tata Motors remains the outlier. With the largest reported demand-supply ratio (nearly 3x) and the least public detail on production capacity or expansion timelines, the company faces pressure to publish a concrete plan.
Why factories cannot add output overnight
Readers often ask why companies with full order books cannot simply run extra shifts. The answer lies in how automotive capacity works. Adding assembly stations does little if battery cells, motors, power electronics or controller supplies stay flat. An EV plant can only build as many vehicles as its scarcest component allows. This is why capacity announcements usually pair plant spending with supplier commitments.
Global battery supply also shapes the outlook. Cell production remains concentrated among a few large producers, and Indian makers sit inside that same global chain. The movement of cells and packs runs through regulated logistics systems that add another layer of complexity.
Mahindra expects meaningful relief from Q4 FY27. Bajaj targets the same quarter for its 80,000-unit monthly Chetak rate. Ather's largest step arrives later, in Q2 FY28. Tata has no dated plan in the public domain. Until these expansions commission and supplier volumes catch up, waiting times will remain long.
Market impact and what it means for buyers
A supply-limited market behaves differently from a demand-limited one. When buyers outnumber vehicles, brands compete on availability and delivery dates rather than discounts. This favors companies with spare plant capacity or strong supplier relationships. It also rewards rivals able to ship product quickly, even with a thinner model lineup.
Tata's EV share rising from about 14 percent to 25 percent of passenger-vehicle sales in one year signals how fast the market is moving. If this pace continues while supply lags, market share could shift toward whoever fixes capacity first. The 2027 expansion dates become competitive milestones as much as engineering ones.
For buyers, the practical advice is straightforward. Ask for a written delivery estimate before paying a deposit. Treat any date beyond the first quarter of 2027 with caution, since major capacity additions arrive then. If a specific model is not tied to a plant expansion in company announcements, assume its queue will not shrink quickly.
For suppliers, the signal is a rising and fairly predictable volume curve. Mahindra's 50 percent output increase, Bajaj's 29 percent lift on Chetak, and Ather's plant plan all pull components forward. Firms that can commit capacity now are likely to secure multi-year orders.
The shift from demand problem to supply problem
Not long ago, the conventional wisdom held that India's EV push would stall on buyer hesitation — questions about range, charging access and running costs. The reported figures suggest much of that doubt has faded. Tata's EV share jumping 11 percentage points in a year is hard to square with a hesitant market. Cost arguments have also moved. Ownership economics increasingly favor EVs once driving patterns and fuel prices are factored in.
The inversion is the real news. A year ago, Tata's EVs were about 14 percent of sales and the discussion was about stimulating demand. Today, the share is about 25 percent and the discussion is about unfilled orders. Four companies in two segments, all pointing at the same bottleneck, make this a sector-wide production story.
India's EV boom has outpaced manufacturing capacity. The next 12 to 18 months will test whether Tata, Mahindra, Ather and Bajaj can turn expansion plans into delivered vehicles. Until then, the showroom queue remains the clearest signal of where the market stands.
