India’s passenger vehicle market appears to be moving beyond the stage where alternative powertrains were considered a niche choice. In August, CNG, hybrid and electric vehicles (EVs) together overtook petrol-powered cars in retail sales for the first time, signalling a broader shift in how buyers are weighing fuel costs, technology and long-term ownership.
Alternative powertrains accounted for 41.9% of passenger vehicle retail sales, marginally surpassing petrol at 40.8%, according to industry data. CNG was the largest contributor, accounting for a 25.2% share, followed by hybrids at 9% and EVs at 7.6%. A year earlier, petrol had led the combined alternative-fuel segment by nearly 11 percentage points. Diesel vehicles, meanwhile, accounted for 17.2% of retail sales.
CNG emerges as the biggest alternative to petrol
The crossover is significant because it is not being driven by a single technology. CNG has emerged as the biggest alternative to petrol, supported by lower running costs. Hybrids are attracting buyers seeking improved fuel efficiency without having to depend on charging infrastructure, while EVs continue to expand their presence in the market.
Favourable running-cost economics and continued hesitation surrounding the transition to E20 fuel are encouraging buyers to opt for CNG, hybrids and EVs. Petrol, however, remains the single-largest individual fuel category.
Among manufacturers, Maruti Suzuki dominated the CNG segment with around a 71% market share, while Tata Motors led the electric passenger vehicle segment with a share of around 43%.
The shift towards alternative powertrains is also visible beyond passenger cars. In the two-wheeler segment, EV penetration increased to 10.7% in August from 7.7% a year earlier, crossing the 10% mark in a non-festive month for the first time. This suggests that electric scooters are increasingly moving beyond early adoption and becoming part of the mainstream commuter market.
Three-wheelers are already much further along in the transition. EVs accounted for 65.3% of sales in August, compared with 56.6% a year earlier, making the category increasingly structurally electric.
Commercial vehicles are starting from a much smaller base, but the EV share more than doubled to an all-time high of 5.2%, from 2.1% a year earlier. This indicates that electrification is beginning to move beyond pilot projects and into regular fleet purchases.
Across all vehicle categories, EV retail sales reached 2.98 lakh units in August, up 52.9% year-on-year. The broader signal is that India’s mobility transition is no longer centred solely on EVs. Consumers are increasingly choosing from a wider range of alternatives to petrol, depending on their usage patterns, prices and the availability of supporting infrastructure.
