Maruti Suzuki has unveiled the WagonR Flex Fuel, making it India's first production car compatible with E85 fuel — a blend of 85% ethanol and 15% petrol. The move signals a significant shift in the country's alternative fuel strategy, offering an immediate solution for reducing emissions without waiting for EV infrastructure to mature. The WagonR Flex Fuel is priced from Rs. 5.99 lakh (ex-showroom) and will be available at select dealerships starting this month.

What is E85 and Why Does It Matter?

E85 is a high-ethanol fuel blend that can reduce greenhouse gas emissions by up to 40% compared to regular petrol. The Indian government has been pushing for ethanol blending to cut oil imports and support farmers. E85 fuel was officially launched in India at Rs. 82.12 per litre, making it cheaper than petrol (currently around Rs. 94/litre in Delhi). However, E85 delivers slightly lower fuel economy — typically 15-20% less than petrol — so the effective cost per kilometre may be comparable or slightly higher.

WagonR Flex Fuel: Key Details

The Maruti Suzuki WagonR Flex Fuel is powered by a 1.2-litre, 4-cylinder petrol engine that has been specially calibrated to run on any blend from E0 (pure petrol) to E85. The engine produces 88 bhp and 113 Nm of torque, identical to the standard WagonR. The flex-fuel version is available in both manual and AMT variants.

  • Price: Rs. 5.99 lakh – Rs. 7.24 lakh (ex-showroom)
  • Fuel Economy: 22.5 km/kg on CNG (CNG variant), 20.5 km/l on petrol, approximately 16-17 km/l on E85 (estimated)
  • Engine: 1.2L K12N Dual Jet, 88 bhp, 113 Nm
  • Fuel Tank: 27 litres (E85 compatible)
  • Warranty: 2 years/40,000 km standard

Maruti says the WagonR Flex Fuel can run on any ethanol-petrol blend without modification, thanks to a fuel composition sensor that adjusts the engine mapping in real time.

E85 Fuel Availability and Pricing

E85 fuel is currently available at select outlets in Delhi-NCR, Maharashtra, Gujarat, Tamil Nadu, and Karnataka. The government plans to expand to 1000 pumps by the end of 2026. At Rs. 82.12 per litre, E85 is about 12% cheaper than petrol, but the lower fuel economy means the running cost per km is roughly similar to petrol. For example, a WagonR running on E85 would cost about Rs. 5.2 per km versus Rs. 4.6 per km on petrol (based on current prices).

How Does It Compare to EVs and CNG?

India's EV adoption is growing — the BBC reported that costly fuel is pushing more Indians to buy EVs, but obstacles like high upfront cost and charging infrastructure remain. The WagonR Flex Fuel offers an alternative that doesn't require a charging station. It also undercuts the CNG variant's running cost (CNG costs around Rs. 3.5 per km) but with lower emissions than petrol. For buyers who can't install a charger at home, flex fuel is a practical bridge technology.

Other Flex-Fuel Cars Coming Soon

Following Maruti's lead, other manufacturers are expected to launch flex-fuel models. According to CarDekho, at least five more flex-fuel cars could be introduced in India soon, including the Hyundai i20, Tata Tiago, and Mahindra XUV300. Toyota has already announced flex-fuel hybrid technology for the Camry and Innova Hycross. This could create a new segment of eco-friendly cars that don't rely on scarce charging infrastructure.

What This Means for Car Buyers

For the average Indian car buyer, the WagonR Flex Fuel offers a way to reduce carbon footprint without the range anxiety of EVs. However, the lower fuel economy and limited E85 pump availability mean it's best suited for city driving where E85 pumps are accessible. The price premium over the standard WagonR (about Rs. 30,000) is modest, and the running cost is competitive with petrol.

Future Outlook

The Indian government's ethanol blending target of 20% by 2030 (E20) is already being pushed forward. E85 is the next step. With Maruti Suzuki commanding over 40% of the passenger vehicle market, the WagonR Flex Fuel could normalise flex-fuel technology for the masses. If E85 pump infrastructure expands as planned, flex-fuel cars could become a mainstream choice, especially in rural and semi-urban areas where ethanol production is high.

Conclusion

The Maruti Suzuki WagonR Flex Fuel is a pragmatic step towards reducing vehicular emissions in India. It offers a cost-effective, low-emission alternative that works with existing fuel infrastructure. While it won't replace EVs, it fills a crucial gap for buyers who want to go green without waiting for the charging network to catch up. As E85 pumps proliferate, the WagonR Flex Fuel could be the right car at the right time.
