Yamaha FZ-S Fi Hybrid Launched: First-in-Segment Hybrid Tech Promises Over 50 Kmpl Mileage
Yamaha continues to lead innovation in the affordable motorcycle segment with the launch of its latest model, the 2025 FZ-S Fi Hybrid. As the first hybrid motorcycle in the 150cc category, it integrates cutting-edge fuel-saving technology, enhancing both efficiency and performance. The mild-hybrid system is similar to the one seen in Yamaha’s Ray ZR scooters, offering improved acceleration, enhanced mileage, and a smoother riding experience.
What’s New in the Yamaha FZ-S Fi Hybrid?
Segment-First Hybrid System
The FZ-S Fi Hybrid features a Smart Motor Generator (SMG) and stop-start technology, which significantly enhances fuel efficiency. This system:
- Automatically stops the engine when idling and restarts it upon clutch engagement, reducing fuel wastage.
- Provides battery-assisted acceleration, ensuring quicker pick-up and a more refined riding experience.
Revamped Design & New Color Options
Beyond the hybrid powertrain, the bike comes with sharper styling elements, including:
- A redesigned fuel tank with an aerodynamic profile.
- Integrated turn signals and air intakes for improved aerodynamics.
- Two new color variants – Racing Blue and Metallic Grey, adding to its sporty appeal.
Engine & Performance
Under the hood, the FZ-S Fi Hybrid is powered by the same 149cc, air-cooled, 4-stroke SOHC engine, delivering:
- 12.4 PS of peak power
- 13.3 Nm of max torque
While the powertrain remains unchanged, the addition of hybrid assistance improves overall efficiency and ride quality.
Fuel Efficiency: How Much Can It Deliver?
Traditionally, the FZ-S Fi provides a mileage of around 45 kmpl under standard riding conditions. However, with the new hybrid system, the bike is expected to achieve an impressive 50 kmpl or more, especially in stop-and-go traffic conditions, where the stop-start system plays a crucial role in saving fuel.
The 2025 Yamaha FZ-S Fi Hybrid marks a significant step forward in two-wheeler innovation, offering a blend of performance, efficiency, and cutting-edge technology. As the first hybrid motorcycle in its segment, it sets a new benchmark in fuel economy and urban commuting convenience. Yamaha’s commitment to sustainability and affordability continues to make it a game-changer in the Indian motorcycle market.
Hybrid Technology & Performance Enhancements
The FZ-S Fi Hybrid is equipped with a Smart Motor Generator (SMG) and a stop-start system, similar to Yamaha’s Ray Z scooters. This mild hybrid system works by
- Shutting off the engine during idling to save fuel.
- Restarting instantly when the clutch is engaged.
- Providing battery-assisted acceleration for a smoother and quicker ride.
