What Is Flex-Fuel? — Quick Overview

Flex-Fuel vehicles are capable of running on:

• Pure petrol
• Ethanol-mixed petrol (E20–E85)
• Higher bio-ethanol blends

This allows:
Lower emissions
Reduced dependence on crude oil imports
Better fuel sustainability

Ethanol is made from agricultural sources (sugarcane, grains, biomass), meaning more income opportunities for Indian farmers.motor mitra

---

Why Flex-Fuel For India?

The Indian government is pushing for higher ethanol blending:

• E20 rollout targeted gradually
• Aim to reduce the oil import burden.
• Boost to the rural agricultural economy.

Currently, production & blending capacity are increasing, and Maruti Suzuki aims to be among the first large OEMs to adopt this alternative fuel strategy.times.motormitra.in

Engine & Mechanical Details

The Maruti Suzuki Fronx Flex-Fuel is expected to be based on the:

1.2L K-Series NA Petrol Engine

• Supports multiple ethanol blends
• Capable of running on E20–E85
• Torque and power may see slight variation vs. petrol.times.motormitra.in

Expected Outputs (Estimated):

• Power: ~88–92 bhp
• Torque: ~113–120 Nm

Transmission Options (Expected):

• 5-Speed Manual
• AMT

Maruti may also add improvements to:

• Fuel system tolerance
• Corrosion protection
• Cold-start performance

Because ethanol contains lower energy density, fuel economy (km/l) may slightly dip, but running cost per kilometer is expected to remain competitive.times.motormitra.in

Performance & Drive Experience

Ethanol-rich blends generally offer better:

• Throttle response
• Octane rating → Reduced knocking
• Smoother combustion

However:

• Cold start calibration is crucial.
• The range may be reduced slightly.

Reliability is expected to remain strong due to Maruti’s calibration expertise.

Expected Mileage

Fuel Type	Expected Efficiency
Petrol (E0/E10)	~18–21 km/l
Flex-Fuel E20–E85	~14–18 km/ltimes.motormitra.in

Even with slightly lower mileage, running costs could remain affordable due to lower ethanol pricing.motor mitra
