Maruti Suzuki to fuel India’s ethanol shift with first flex-fuel car that’s coming soon

is in for a revolution. In a push for , is set to unveil the country’s very first mass-market flex-fuel passenger vehicle on Thursday, June 4.

The highly anticipated reveal will take place at Delhi’s Taj Palace, strategically timed just ahead of .

The vehicle, heavily anticipated to be a flex-fuel iteration of the popular WagonR, follows a report by ETNow citing The Informist last month, which had accurately hinted that the auto giant’s ethanol-friendly workhorse would break cover this June.

The high-profile event underscores the political and economic weight behind the launch, with Union Minister for Road Transport and Highways and Union Minister for Petroleum and Natural Gas Hardeep Singh Puri both slated to attend.

“Vehicles with such flex-fuel engines are going to be introduced on a large scale soon. On the occasion of Environment Day this year, there is a programme in Delhi where will launch vehicles running 100 percent on ethanol,” Gadkari had earlier said.

What exactly is a flex-fuel car?

For the everyday driver, the concept of a Flexible Fuel Vehicle (FFV) might sound futuristic, but the mechanics are beautifully practical.

A flex-fuel car features an internal combustion engine capable of running on varying blends of petrol and ethanol.

While standard Indian cars on the road today are tuned to handle E20 (a blend of 20 percent ethanol and 80 percent petrol), Maruti’s new offering is designed to comfortably operate on much higher blends, all the way up to , which is 100 percent pure ethanol.

To make this happen, engineers had to rewrite the internal playbook.

Because ethanol is chemically more corrosive than petrol and naturally absorbs moisture, a regular fuel tank would deteriorate.

Maruti’s flex-fuel prototype is likely to features completely redesigned injectors, fortified fuel lines, robust seals, and a specially calibrated engine management system to handle the unique properties of ethanol without breaking a sweat.

Why this launch matters

The unveiling marks a massive philosophical shift in India’s automotive industry.

Historically, the green debate has been dominated by Electric Vehicles (EVs). However, as Gadkari has repeatedly pointed out, India cannot rely on a single silver bullet to fix its environmental and economic vulnerabilities.

According to recent statements made by the minister at automotive industry conferences, India currently imports nearly 87% of its crude oil requirements, racking up a staggering Rs 22 lakh crore fossil fuel import bill.

“We should minimise the use of petrol, diesel, and gas because 87% of these fuels are imported into our country. They not only cause pollution but also increase imports,” Gadkari candidly warned, noting that alternative fuels are the only viable long-term solution.

By shifting the fuel source from deep-sea oil wells to local agricultural fields, India hits a three macroeconomic goals.

First, it strengthens national energy security by shielding the economy from volatile geopolitical crises that frequently disrupt global oil supplies and inflate local fuel prices.

Second, it provides a massive economic boost for domestic farmers, as ethanol is brewed entirely from homegrown sugarcane molasses, corn, broken rice, and agricultural waste. This ensures that money spent on fuel goes straight into the Indian rural economy rather than being sent abroad to foreign oil cartels.

Finally, this transition drives massive decarbonisation across the transport sector because ethanol burns significantly cleaner than petrol, directly targeting and reducing the choking tailpipe emissions that consistently afflict major Indian metros.

The road ahead

While Maruti Suzuki’s technology is locked, loaded, and officially cleared under revised government vehicle testing norms, the transition won’t happen overnight.

More crucially, a car is only as good as the fuel you can put in it.

The Indian government’s messaging on E100 has transformed from a distant environmental aspiration into an urgent economic directive.

Speaking at the Indian Federation of Green Energy’s Green Transport Conclave, Gadkari had made it explicitly clear that India must confidently aim for a 100 percent ethanol ecosystem.

Pointing to the prolonged geopolitical instability and oil trade disruptions in West Asia, Gadkari underscored that moving completely away from petrol is no longer just about cutting carbon footprints—it is an absolute necessity for national energy self-reliance.

“In the near future, India should aspire to achieve 100 per cent ethanol blending,” Gadkari asserted. “Today, we are facing an energy crisis due to the war in West Asia, so it is necessary for us to become self-reliant in the energy sector.”

To make this transition a reality, the Ministry of Petroleum and Natural Gas, alongside state-run oil marketing companies, is already laying down the physical infrastructure for an E100 future.

The government has committed to setting up approximately 5,000 dedicated E100 dispensing stations across the country over the next two years. These specialised stations will feature upgraded, corrosion-resistant tanks and pipes designed to safely handle pure ethanol.
