Financial Year 2026 was one of two halves for India's passenger vehicle industry — and it is the second one that the sector will remember. After a largely flat first six months, the Goods and Services Tax (GST) 2.0 rollout injected fresh energy into consumer demand, combining with a strong festive season to push full-year sales growth at an 8% year-on-year rise.

"The industry witnessed a strong rebound in the second half, posting double-digit growth, supported by GST 2.0 implementation and a robust festive season," said Shailesh Chandra, MD & CEO, Tata Motors Passenger Vehicles (PV) in a regulatory filing last week.

Yet even as the industry savours a record year, having sold 2.96 crore units in total, FY27 opens with an uncomfortable question: how long can the momentum hold?

Gas supply shortages are already straining production at component makers — some of whom have temporarily shut specific units — even as OEM production lines hold for now. A prolonged conflict could deepen supply chain disruptions and weigh on household budgets, a risk the sector cannot afford to ignore.

Input Costs Rise, Car Price Hikes Follow

The West Asia conflict is beginning to hit closer to home for Indian consumers, with mass market car prices set to rise. Commodity costs have been building for months, and the geopolitical turmoil has only compounded the strain, industry executives said.

"The situation is very dynamic,” Partho Banerjee, Senior Executive Director – Sales & Marketing at Maruti Suzuki said during a recent media call, adding that a price revision is now imminent. "Very soon we are going to review — we need to increase the prices and pass it on to our customers."

The timing is particularly concerning for the small car segment. The GST reduction had unlocked a fresh wave of demand among price-sensitive, entry-level buyers — many of them first-time car owners. A price increase now risks undermining precisely that momentum.

It may be noted that Tata Motors and Mahindra & Mahindra (M&M) have already announced a price hike on ICE range of passenger vehicles, effective April.

The pressure, however, runs deeper than the showroom. As reported by The Core last month, the more immediate industry concern is not a production halt, but intermittent disruptions and supply chain bottlenecks at facilities that could ripple through the broader production line.

Production Constraints Are On A Watch

The most immediate risk of West Asia-driven gas shortages lies with Tier 1 and Tier 2 component manufacturers — particularly those running gas-dependent processes such as foundries, forging, casting. It also extends to the broader MSME supplier ecosystem, which lacks the scale or financial flexibility to pivot quickly to alternate fuels. Even OEM paint shops rely heavily on gas-fired heating systems.

For now, the production lines are holding. "So far our operations are running perfectly normal," Rahul Bharti, Executive Director – Corporate Affairs at Maruti Suzuki, said during a recent media call, though he acknowledged that concerns around future gas supplies are beginning to surface.

Puneet Gupta, Director – Automotive at S&P Global Mobility, told The Core that OEMs are falling back on captive coal and diesel plants for gas-dependent manufacturing operations — a pivot to older energy sources that the industry had largely moved away from in favour of gas, given its lower cost and better emissions profile.

Maruti Suzuki is also actively working to manage its export exposure, with the Middle East accounting for approximately 12.5% of its total outbound shipments this year.

On costs, longer shipping routes have added to Maruti's freight burden. The carmaker said it is absorbing those costs for now — but not without reservation. "We will do everything to minimise the impact of the war, but of course, to some extent you cannot go totally unaffected," Bharti said.

According to CS Vigneshwar, President of the Federation of Automobile Dealers Association (FADA), the industry currently has some buffer to work with. Dealerships are carrying approximately 28 days of average stock, with component manufacturers and OEMs holding an additional few weeks each, translating to roughly a month to a month-and-a-half of inventory across the chain.

“If it (the war) continues beyond this month we are definitely going to have supply issues. Even right now I heard from OEMs that the government has asked them to reduce the usage of gas,” he told The Core Report.

However, Vigneshwar cautioned that if OEMs are directed to scale back vehicle supplies, production could fall by as much as 25-30%.

The caution extends beyond passenger vehicles. In commercial vehicles, Vinod Sahay, Executive Chairman – SML and President – Aerospace, Defence, Trucks, Buses & CE, Mahindra & Mahindra, said replacement demand and government-led infrastructure projects are expected to lend support to volumes, but warned that fuel cost volatility and supply chain constraints could weigh on sentiment. "The trajectory for FY27 remains mixed," he said.

Petrochemical Crunch For Components

To manage gas supplies, the government ordered refineries and oil marketing companies to suspend crude-based petroleum product supplies to downstream industries, prioritising domestic LPG production instead. Major producers, including Indian Oil's Paradip propylene unit and GAIL's Uttar Pradesh polyethylene facility, were forced to halt operations temporarily.

The ripple effect hit downstream players hard. Andhra Petrochemicals, Tamilnadu Petroproducts and Kirloskar Ferrous suspended production, as reported by The Core last month. In effect, crude is being diverted to make cooking gas rather than petrochemicals — the essential building blocks for auto parts and components.

Vinnie Mehta, Director General of the Automotive Component Manufacturers Association (ACMA), told The Core that most component makers have now pivoted to alternate fuels — diesel and electric — to manage the LPG shortage in manufacturing processes, but warned that the cost pressure is severe.

"The challenge on cost escalation and input costs exists in a big way. Raw materials like styrene and carbon black have seen a 100% increase in cost," he said.

The government has since increased commercial LPG supply and exempted customs duty on 40 critical petrochemical products, until June 30. Kirloskar Ferrous has resumed operations by pivoting to alternate fuels, but the other two plants remain suspended.

Mehta acknowledged the customs duty exemption as a positive step, but added, “Supplies are constrained. The exemption could help — but only if it is passed on in all earnestness.”

"While customs duty exemptions offer short-term relief, their effectiveness diminishes if the West Asia conflict persists. Prolonged instability keeps freight costs elevated while extended transit times disrupt production schedules — creating a critical lag between demand and supply," Swathi Seshadri, Energy Specialist (Petrochemicals, South Asia) at IEEFA, told The Core.

She flagged that ethylene prices are already on an upward trajectory, with polyethylene prices in Asia surging 40-50% since the war began.

The squeeze is feeding directly into vehicle manufacturing costs. High Density Polyethylene (HDPE) — a critical material used in interior and exterior auto components — is among the affected inputs.

On the supply chain front, Gupta acknowledged that the pressure is real but manageable for now. The industry's experience navigating the Covid-19 pandemic has made it significantly more adaptive. "OEMs have pretty tight inventory tracking and therefore there isn't a major impact on production as of now," he added.

Crisil Ratings has flagged that auto component manufacturers have limited flexibility to pass on rising production and freight costs to customers, with any pass-through expected to be significantly lagged, weighing on margins.

On the ground, some component makers are taking measures to retain their workforce — distributing induction cookers to workers. ACMA, Mehta said, is working on broader best practices to help the sector retain its labour force through the disruption.

Dealers Tread Carefully

FADA's latest survey reveals that 53.2% of dealers have experienced some form of supply or dispatch disruption linked to the ongoing conflict, with 17.1% reporting significant delays of three or more weeks. While the impact has been most pronounced in the commercial vehicle segment, passenger vehicle and two-wheeler dealers have also flagged selective variant-level delays.

On the demand side, 36.5% of dealers report that rising or expected fuel prices are moderately to significantly affecting customer purchase decisions, thereby elongating decision cycles.

For the April- June quarter, OEM supply disruption and model unavailability is the second-most cited risk, flagged by 30.5% of dealers.

Estimates Trimmed

The caution is already showing up in forecasts. Rating agency ICRA has projected PV segment's wholesale volume growth to moderate to 4-6% in FY27 from 8% in FY26, citing the elevated FY26 base and the West Asia conflict as key constraints.

Crisil Intelligence is more conservative. Hemal Thakkar, Senior Director and Senior Practice Leader at the firm, said the crisis has already dented sentiment across automobile segments, prompting a downward revision in growth forecasts — with the GST 2.0 tailwind that was expected to carry into FY27 now complicated by the geopolitical overhang.

Thakkar has warned that the year's trajectory will hinge heavily on first-half performance. "The growth in FY27 will remain challenging if the first half doesn't see reasonable growth, as the high base effect in the second half will weigh in on overall fiscal growth," he said.

Crisil's projections — premised on a normal monsoon and the West Asia crisis abating in the near term — peg domestic PV volume growth at a modest 3-5%.

Chandra acknowledged as much, noting that while SUVs, CNG and EVs are expected to drive the demand during the year, the industry would need to "closely monitor geopolitical developments to mitigate potential supply-side risks."
