The fuel consumption of the S-Max is 7.4 liters per 100 kilometers. The 2.3L naturally aspirated engine features an aluminum alloy block, dual reverse-mounted balance shafts, and i-VCT variable intake cam timing, delivering a maximum power of 117.6 kW at 6500 rpm and a peak torque of 205 Nm at 4000 rpm. Here is additional information: Ford S-Max exterior design: To avoid the visual appearance of a typical MPV, the rear window of the S-Max was intentionally reduced in size, seamlessly blending with the downward-sloping roofline. The red high-mounted brake light is positioned on the small roof spoiler, while a pair of chrome exhaust tips continue to emphasize Ford's sporty spirit.

My old S-MAX has been running for nearly ten years, and the 2.3L naturally aspirated engine is really fuel-consuming in city driving. During daily commutes with heavy traffic, the dashboard typically shows 12-13 liters per 100 km, and it can jump to 14 if there are too many red lights. On the highway, it stabilizes around 8.5 liters, and the lowest I've seen was 7.9 when cruising steadily at 90 km/h. The worst part is running the AC in summer—when the compressor kicks in, the fuel consumption directly increases by half a liter. The car weighs close to 1.8 tons and has high drag, so seeing new hybrids easily hitting just 5 liters makes every refuel painful. But its space is truly impressive—it can fit seven people plus all our luggage for family trips, so the higher fuel consumption is something I can live with.

After studying numerous forum test data, it's evident that the fuel consumption of the S-MAX is significantly affected by its transmission. The 2007 model's 4AT transmission has a conservative programming, often maintaining higher RPMs, resulting in urban fuel consumption generally around 11-12L/100km. Later versions with the 5AT transmission performed better, but user feedback still indicates a combined fuel consumption of 10-11L. Observing the instant fuel consumption gauge, it can exceed 20L during hard acceleration but drops to zero when coasting. The most significant impact actually comes from load—carrying seven passengers consumes about 1.5L more than when unloaded. Tire pressure is also crucial; maintaining 2.5bar with monthly checks can save a considerable amount.

Three practical tips for driving the S-MAX more fuel-efficiently. First, avoid aggressive starts as the weak low-end torque means heavy throttle just wastes fuel. Second, anticipate red lights early and coast - its gliding distance is remarkably long. Third, keep side windows closed above 80 km/h as wind noise increases drag. My urban school-run consumption stays around 11L/100km (manual versions may do better). Always refuel at reputable stations - substandard gasoline causes incomplete combustion. Regular air filter cleaning maintains optimal airflow.

My friend just took over a used S-MAX and keeps complaining about the high fuel costs. Last week, I accompanied him on a provincial highway trip and made some discoveries. The car is most fuel-efficient at 40-60 km/h, maintaining a steady cruise can achieve 8L/100km. However, in city driving with frequent starts and stops, the engine efficiency drops, especially when the AC is on—the engine has to both drive the car and power the compressor. We tested during morning and evening rush hours, and found that using the AC consumes an extra 1.7L/100km. Later, we switched to a pair of low rolling resistance tires for him, which reduced tire noise and also lowered fuel consumption by 0.3L/100km. Actually, this car's fuel consumption is similar to the older Odyssey model, but it wins with a used price that's 20,000-30,000 RMB cheaper.

From a technical perspective, the fuel consumption bottleneck of the S-MAX lies in its transmission efficiency. The outdated 4AT gearbox suffers from over 20% power loss, far inferior to modern 6AT or CVT transmissions. Its engine compartment layout also leads to slow heat dissipation, causing the cooling fan to frequently activate during stop-and-go summer traffic, resulting in additional fuel consumption. Some owners have modified with lightweight alloy wheels - reducing weight by 1kg saves approximately 0.1L per 100km. Actually, the most hassle-free solution is annual carbon deposit cleaning, especially for direct injection engines which tend to accumulate coke deposits on valve backs. After walnut shell blasting cleaning last year, my engine runs smoother with 0.8L/100km fuel reduction on the same route.
