Maruti Suzuki Steps Into the Green Mobility Era: Maruti Suzuki has taken a significant leap toward sustainable mobility with the unveiling of the Maruti Suzuki Fronx Flex-Fuel (FFV) at the 2025 Japan Mobility Show. This marks one of India’s earliest steps into the ethanol-powered car segment, signaling the company’s readiness for India’s E20–E85 fuel transition.
The Fronx Flex-Fuel is based on the popular Fronx compact SUV but re-engineered to run on both petrol and ethanol-blended fuels (up to E85). With India actively pushing ethanol adoption, this move perfectly aligns with the nation’s “Cleaner and Greener Future” vision.

2. Engine and Performance — Dual Power for a Cleaner Drive
Under the hood, the Fronx Flex-Fuel features a 1.2-litre K-Series DualJet Naturally Aspirated engine, modified to handle ethanol blends ranging from E20 to E85.
| Specification | Details |
|---|---|
| Engine Type | 1.2-litre DualJet Petrol (Flex-Fuel Compatible) |
| Fuel Compatibility | Petrol + Ethanol (E20 to E85) |
| Expected Mileage | Up to 30 km/l (depending on blend ratio) |
| Transmission | 5-speed Manual / AMT |
| Launch Timeline | Early 2026 (India) |
The engine has undergone FFV-specific tuning with upgraded injectors, valves, and ethanol-resistant components to ensure performance consistency. Drivers can expect smoother acceleration, lower emissions, and a noticeable reduction in running costs.
3. Design — Familiar Yet Future-Ready
Visually, the Fronx Flex-Fuel SUV retains its signature SUV-coupe design but now features green-themed graphics and a “Flex-Fuel” badge. The model showcased in Japan sported black alloy wheels and subtle cosmetic updates that highlight its eco-friendly DNA.
While maintaining the same proportions — 3,995 mm in length and 1,765 mm in width — the prototype also introduced international features like ADAS, a 1.5-litre engine, and Suzuki’s AllGrip AWD system, hinting at potential upgrades for the Indian market.
4. Interior — Premium, Practical, and Eco-Inspired
Inside, Maruti Suzuki has refreshed the Fronx Flex-Fuel’s cabin to align with modern comfort expectations. The updated interior includes:
- Dual-tone dashboard finish
- Ventilated front seats
- 9-inch SmartPlay Pro+ infotainment system
- Wireless Android Auto & Apple CarPlay
- Cruise control & automatic climate control
- Six airbags with ESP
The cabin feels familiar yet refined — a balance of comfort and eco-conscious design.

5. Why Flex-Fuel Matters — India’s Ethanol Revolution
The Maruti Fronx Flex-Fuel isn’t just a new car — it’s a strategic response to India’s growing ethanol mission. Ethanol is a renewable biofuel made from sugarcane, maize, and agricultural residues, making it cheaper and cleaner than petrol.
With India already rolling out E20 fuel, the shift to E85-compatible engines will reduce the country’s oil imports while supporting local farmers and rural economies. Suzuki’s multi-pathway approach — promoting ethanol, hybrid, biogas, and EV technologies — reflects its practical and inclusive sustainability vision.
6. Expected Price and India Launch Timeline
According to reports, Maruti Suzuki Fronx Flex-Fuel SUV will launch in early 2026 and is expected to be priced between ₹8 lakh and ₹10 lakh (ex-showroom). The vehicle could be first introduced in India before expanding to other emerging markets like Brazil and Indonesia.
7. Expert Opinion — A Bridge Between Petrol and Electric
While EV adoption is growing, flex-fuel cars like the Fronx FFV serve as an immediate and affordable solution for India’s green mobility journey. With existing infrastructure (petrol pumps) and no charging dependency, flex-fuel technology offers a realistic bridge between conventional petrol cars and full EVs.
