At the 2025 Japan Mobility Show, Maruti Suzuki surprised everyone by showcasing the Fronx FFV (Flex-Fuel Vehicle) — a car that runs not just on petrol but also on ethanol blends up to E85! It’s a glimpse into how Maruti is preparing India for a greener, more flexible fuel future. While it looks similar to the regular Fronx sold in India, this FFV version hides a major upgrade under its hood — one that could redefine affordable sustainability for Indian roads.
Maruti Fronx FFV: What Makes It Different
Unlike traditional petrol or diesel cars, the Maruti Fronx FFV uses a 1.2-litre K-Series Dual Jet, Dual VVT flex-fuel engine, specially tuned to handle ethanol blends ranging from 20% to 85%. It promises the same peppy drive as the regular Fronx but with lower emissions and cleaner combustion.
Inside, Maruti hasn’t gone radical — the cabin retains the premium dual-tone finish, SmartPlay infotainment system, and connected tech features. What’s exciting is how seamlessly Maruti has adapted this powertrain for daily usability — no compromise on performance or mileage, yet far more eco-conscious.

India-Ready Sustainability: Maruti’s Big Bet
Maruti Suzuki India has already confirmed its commitment to ethanol-compatible vehicles for the coming decade. The Fronx FFV showcased in Japan is part of that roadmap, making it clear that India’s largest carmaker is serious about cutting carbon without killing affordability.
The model is fully localized for Indian conditions, tested for tropical weather, variable fuel quality, and long-term durability. It’s not just a prototype — it’s a preview of what’s coming soon to Indian showrooms.
Exterior and Interior Design: Familiar Yet Future-Ready
On the outside, the Maruti Fronx FFV maintains the stylish coupe-like stance, muscular bumper, and bold LED DRLs that made the Fronx a hit in India. However, subtle “FFV badging” and green-themed highlights hint at its eco-forward identity.
Inside, the car continues Maruti’s blend of comfort and tech — a 7-inch infotainment screen, wireless Android Auto/Apple CarPlay, and a 360° camera. The FFV retains the same spacious cabin layout, making it ideal for urban drivers who want both style and sustainability.

Maruti Fronx FFV: When Will It Launch in India?
According to insiders, Maruti is planning to launch the Fronx FFV in India by mid-2026. The company is currently working with the Indian government and oil companies to ensure ethanol fuel availability across major cities before rollout. Expect the FFV to debut as a limited edition or pilot model, followed by a nationwide launch once ethanol distribution networks expand.
Why the 2025 Japan Mobility Show Was a Big Deal for Maruti
Japan Mobility Show 2025 wasn’t just about futuristic EVs — it was about innovation that fits reality. Maruti’s Fronx FFV stood out because it bridges the gap between affordability and sustainability. While global automakers push expensive EVs, Maruti’s approach — using flex-fuel technology — could be the bridge India needs before full EV adoption.
Final Thoughts
The Maruti Fronx FFV is more than just another crossover — it’s a symbol of how Indian engineering is evolving for a cleaner tomorrow. With ethanol production ramping up and fuel policies aligning, the Fronx FFV could be the perfect in-between solution for millions of Indian drivers who want to go green without going broke.
