Ford S-MAX uses a 2.3-liter naturally aspirated engine. Here are the specific details about the 2.3-liter naturally aspirated engine: Configuration of the naturally aspirated engine: The 2.3-liter naturally aspirated engine in the Ford S-MAX delivers 160 horsepower and a maximum torque of 205 Nm. This engine can output its maximum power at 6,800 rpm and reach its peak torque at 4,000 rpm. It is equipped with i-VCT technology and multi-point fuel injection, and features an aluminum alloy cylinder head and block. Transmission of the naturally aspirated engine: It is paired with a 6-speed transmission, which offers smooth gear shifts. At low speeds, gear changes are seamless without noticeable jerking, and the transmission responds actively during driving. In practical driving scenarios, this engine demonstrates strong instantaneous power, delivering continuous and robust performance whether during initial acceleration or rapid acceleration.

My friend drove a 2017 Ford S-Max equipped with a 2.0-liter EcoBoost engine producing around 245 horsepower. Paired with an automatic transmission, it delivered exceptionally smooth driving with quick acceleration and no sluggishness. This engine technology is quite advanced, combining direct fuel injection and turbocharging, resulting in decent fuel efficiency—about 8 liters per 100 km in city traffic—and even lower consumption on highways. Compared to older naturally aspirated engines, the EcoBoost offers much better power responsiveness with almost no noticeable lag during driving. I remember testing it on uphill climbs—the low-end torque was sufficient, and passengers in the back never complained. Maintenance is straightforward, requiring regular oil and filter changes, and parts are easy to find without much hassle. Additionally, Ford has invested heavily in the EcoBoost series, ensuring good reliability with few issues even after ten years. One minor drawback is occasional slight vibrations during cold starts in winter. Overall, this engine is well-suited for family MPVs, striking a great balance between performance and fuel economy.

I once rented a Ford Mondeo for a long-distance trip, equipped with a 2.0L Duratorq series diesel engine. The power delivery was quite solid, with maximum torque kicking in early at low revs, making highway overtaking effortless. The fuel efficiency was outstanding, achieving under 7L/100km on highways and just over 9L/100km in city driving, with cost-saving being its highlight. Engine noise was well-controlled, and cabin insulation was enhanced, so wind noise overshadowed the engine at high speeds. The steering response matched the engine well, offering nimble handling without the jerky feel of some older cars. In terms of maintenance, diesel engines are durable with longer service intervals, but remember to use genuine diesel filters to prevent clogging issues. This car is ideal for families who frequently travel long distances, offering ample space and reliable engine performance. On a related note, Ford's diesel engines are globally popular, especially the European models, which meet Euro 6 emission standards with clean exhaust.

I've studied the engine evolution of the Ford S-MAX. The first-generation 2006 model featured a 2.0L Duratec gasoline engine with 165 horsepower. Later in 2015, it was upgraded to a 1.5L EcoBoost engine, delivering stronger power while being more fuel-efficient. On the diesel side, it transitioned from the older 2.0 TDCi to the current Duratorq, with improved emission efficiency through technological advancements. Each version closely follows Ford's innovations, such as the EcoBoost utilizing turbocharging to optimize responsiveness. With each model update, engine specifications change accordingly—the new generation increased horsepower by 20% to meet modern demands.
