Car Fuel Mix India September 2026: Petrol Is Back in Front, but Only Just

Petrol cars won back the top spot in September, and the margin is thinner than the headline suggests. The car fuel mix India September 2026 shows petrol at 41.27% of passenger vehicle retail, with CNG, hybrids and EVs together at 41.00%.

The Split in Plain Numbers

According to Park+’s summary of the FADA data, petrol and ethanol blends made up 41.27% of passenger vehicle retail in September 2026, down from 47.18% a year earlier. CNG, hybrid and EV combined took 41.00%, up from 35.06% in September 2025.

Inside that 41%, hybrids held 9.44% and EVs 8.45%. In August, alternative fuels had outsold petrol for the first time, and September flipped it back by a hair. Autocar India’s retail report adds that hybrid and EV shares rose month on month while CNG’s share fell.

EVs Are the Fastest Mover

Electric cars are the clearest growth story. FADA’s EV retail figure for the month was 36,108 units, up 94.56% on September 2025, and up 17.63% on August. Tata led with 14,791 units, which works out to about 41% of all electric car retail, followed by Mahindra at 7,780 and JSW MG at 5,242. Between them, those three brands account for roughly three out of every four electric cars sold.

VinFast came fourth with 2,964 units, up from just 6 a year earlier, as covered in our VinFast September sales report. Maruti Suzuki managed only 1,104 EVs, down nearly 22% on August, which tells you how far the biggest carmaker still is from leading this segment.

The Year-on-Year Shift Is the Real Story

Look at the movement in a year, not a month. Petrol fell from 47.18% to 41.27%, a drop of about 5.9 percentage points. CNG, hybrid and EV rose from 35.06% to 41.00%, a gain of almost exactly the same size. Nearly every point petrol lost went to an alternative fuel.

EV penetration shows it most clearly. According to the same data, EVs were 5.7% of retail in September 2025, 7.6% in August 2026 and 8.5% in September 2026. That is a steady climb, not a one-off spike.

Hybrids: Quiet but Real

Hybrids are not as loud as EVs, yet they hold a bigger share at 9.44%. Our own strong hybrid sales analysis found flat retail in September with Toyota still holding about 80% of the segment. That means the hybrid share is being driven largely by one brand, while Maruti and others try to catch up.

For buyers who cannot rely on a home charger, hybrids offer a middle path. They run on petrol with no charging worry, and they deliver better mileage in city traffic. That helps explain why hybrids hold such a solid share without much noise.

Why CNG Slipped

CNG’s share fell month on month, while hybrid and EV shares rose. FADA’s data does not say why, so anything we add is opinion. Our read is that buyers who once picked CNG purely for low running cost now have more options, from hybrids to cheaper EVs, and some of them are choosing those instead.

One caution: the data shows the movement, not the cause. A one-month dip does not make CNG a dead end, especially for high-mileage drivers in cities with good CNG pumps.

What This Means for Indian Buyers

If you drive about 40 km a day in a city like Ahmedabad or Pune, the numbers say you are not alone in looking beyond plain petrol. Roughly 4 in 10 new cars sold in September were CNG, hybrid or EV.

Our practical view: EVs make sense if you can charge at home and your car is a second vehicle. Hybrids suit people who want one car for everything. Petrol remains the simplest choice for low-run buyers who want the lowest upfront price.

Final Verdict

The car fuel mix India September 2026 headline, that petrol is back in front, hides the real trend: alternative fuels are within a whisker of petrol and growing faster. Petrol was at 47.18% only a year ago.

If you are buying in the next few months, do not choose a fuel based on one month’s data. Choose it based on how many kilometres you drive, where you can charge or refuel, and how long you plan to keep the car.
