Why Does Ford Still Insist on Using Three-Cylinder Engines?

Ford insists on using three-cylinder engines primarily to achieve better single-cylinder torque in small-displacement engines while reducing engine weight, slightly balancing acceleration performance in the context of emission reduction. Below is a relevant introduction to automotive engines: 1. Concept: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. 2. Classification: Internal combustion engines, external combustion engines, meaning the fuel burns outside the engine, gas turbines, jet engines.

As a long-time Ford enthusiast, I've found their persistence with three-cylinder engines isn't a rash decision. With increasingly stringent emission regulations in Europe and China, three-cylinder engines offer smaller size and lighter weight, reducing vehicle fuel consumption by about 10%. When paired with turbocharging, their power output rivals older four-cylinder models. At auto shows, I've examined their new engines - Ford has done an excellent job controlling vibrations through balance shafts and hydraulic engine mounts. More importantly, three-cylinder engines have a cost advantage with 15% fewer parts, saving thousands in manufacturing costs per vehicle and making models like the Focus more affordable for families. While users need an adaptation period, the fuel savings from three-cylinder engines at equivalent displacement can offset the cost difference within a year.

From an automaker's strategic perspective, Ford's bet on three-cylinder engines is a masterstroke. At last year's industry forum, engineers mentioned that three-cylinder powertrains are more compatible with hybrid systems, leaving more space for battery packs. Take Ford's Puma Hybrid as an example—it directly uses the three-cylinder engine as a generator, achieving a combined fuel consumption of just 4L. While the North American market resists three-cylinder engines, European regulations require a 50% reduction in new vehicle carbon emissions by 2030, forcing Ford to plan ahead. Their 1.5T three-cylinder engine is now in its third generation, with optimized piston strokes boosting low-end torque by 12%. Despite the mixed reputation of three-cylinder engines, refining existing platforms is clearly more cost-effective than developing an entirely new four-cylinder engine.

As someone who drove a three-cylinder Fiesta for half a year, here's my real-world experience. You can definitely feel slight steering wheel vibrations at startup, but once moving, it's indistinguishable from a four-cylinder. This car is super fuel-efficient for city commuting - 5.3L/100km burns 1L less than my friend's same-displacement four-cylinder. Ford probably insists on three-cylinders for two reasons: first, cheaper maintenance (one fewer spark plug saves ¥200 annually); second, more spacious engine bay (last time I changed the air filter, I could reach it by hand - maintenance convenience crushes some four-cylinders). For regular owners, the saved fuel and maintenance costs are what really matter.
