Quick Answer: The Yamaha FZ-S Fi V4 / Hybrid (149.0cc) delivers a real-world mileage of 45–49 km/l in city traffic, 48–52 km/l on highways, and an owner-reported mixed average of 45–50 km/l, against a claimed figure of 60.0 km/l. At 47 km/l and an illustrative petrol price of ₹105/litre, its running cost is ₹2.23/km (₹2.17/km in Delhi). Related reading: Yamaha FZ-S vs TVS Apache RTR 160 mileage comparison.
Claimed Mileage vs Real-World Efficiency of Yamaha FZ-S Fi V4 / Hybrid
Evaluating yamaha fz-s fi hybrid mileage requires separating five distinct figures: ARAI-certified laboratory claims, independent city/highway road tests, owner-reported mixed averages, dashboard readouts, and calculated petrol costs. Under standardized Indian Driving Cycle (IDC) dynamometer testing, the Yamaha FZ-S Fi V4 / Hybrid is certified at 60.0 km/l. Because lab rollers eliminate wind drag, gradients, pillion weight, and signal idling, on-road efficiency is typically 10% to 18% lower than the brochure rating.

Driven by a 149.0cc (Air-cooled, 4-stroke, SOHC, 2-valve Blue Core FI engine (with SMG Hybrid on Hybrid trim)) motor producing 12.2 bhp @ 7,250 rpm and 13.3 Nm @ 5,500 rpm through a 5-speed transmission, the Yamaha FZ-S Fi V4 / Hybrid weighs 136 kg. Key efficiency hardware includes 136 kg light kerb weight, Traction Control System (TCS), single-channel ABS, 140/60-R17 radial rear tyre, and efficiency-focused Blue Core tuning. Across variants (FZ-S Fi V3, FZ-S Fi V4 DLX (with Traction Control System & Y-Connect), FZ-S Fi Hybrid (SMG Assist)), core engine mapping remains identical.

Table 1: Yamaha FZ-S Fi V4 / Hybrid Claimed vs Real-World Mileage & Range
| Efficiency Metric | Mileage (km/l) | Tank Range (13.0L) | Classification & Condition |
|---|---|---|---|
| Manufacturer Claimed (ARAI) | 60.0 km/l | 780 km | Official certified laboratory cycle |
| Independent City Test | 45–49 km/l | 585–637 km | Tested in urban stop-and-go traffic |
| Independent Highway Test | 48–52 km/l | 624–676 km | Cruising steady at 70–85 km/h |
| Owner-Reported Mixed | 45–50 km/l | 585–650 km | Owner average (solo + occasional pillion) |
| Heavy Gridlock / Hard Throttle | 41–44 km/l | ~546 km | Estimated extreme traffic or high-rpm load |
Speed-Wise Fuel Economy, Top Speed (115 km/h) and Gearing
Aerodynamic drag rises with the square of speed, rapidly increasing fuel demand above 65 km/h. At 35–45 km/h in 4th or top gear, the Yamaha FZ-S Fi V4 / Hybrid operates under light load and returns 49–51 km/l unless traffic forces frequent downshifts.
Its peak thermal efficiency window is 70–85 km/h in top gear, delivering 51–53 km/l on open roads. Pushing toward its 115 km/h flat-road top speed triggers rich fuel mapping, dropping economy to 44–46 km/l at 80 km/h and 38–40 km/l near full throttle.
Daily, Monthly and 1,000 km Petrol Running Costs
Using the formula Petrol Cost = (Distance ÷ Mileage) × Fuel Price at a benchmark 47 km/l, riding 1,000 km consumes 21.28 litres. The table below compares verified October 2026 prices in Delhi (₹102.12/L) and Mumbai (₹111.21/L) alongside an illustrative ₹105.00/L national benchmark.

| Riding Scenario (25 Days/Mo) | Distance | Fuel (@ 47 km/l) | Delhi (@ ₹102.12/L) | Mumbai (@ ₹111.21/L) | Baseline (@ ₹105/L) |
|---|---|---|---|---|---|
| 20 km/day Urban | 500 km | 10.64 L | ₹1,086 | ₹1,183 | ₹1,117 |
| 40 km/day Standard | 1,000 km | 21.28 L | ₹2,173 | ₹2,366 | ₹2,234 |
| 60 km/day Suburban | 1,500 km | 31.91 L | ₹3,259 | ₹3,549 | ₹3,351 |
| 1,000 km Benchmark | 1,000 km | 21.28 L | ₹2,173 | ₹2,366 | ₹2,234 |
Real-World Variables and Conditional Buying Verdict
Tyre pressure 5 PSI below recommended settings (25–28 PSI front, 32–36 PSI rear with pillion), clogged air filters, or heavy two-up loads can reduce mileage by 4–7 km/l. Conditional Verdict: Priced at ₹1,23,000 – ₹1,35,000 ex-showroom, the Yamaha FZ-S Fi V4 / Hybrid suits commuters wanting 45–50 km/l efficiency, 136 kg agility, and relaxed cruising at 70–85 km/h. Riders needing sustained 85–100 km/h highway pace should consider a larger displacement segment.
