The new Focus is equipped with three-cylinder engines across the entire lineup. The methods for engine are: 1. Regularly change the engine oil and oil filter; 2. Keep the crankcase well-ventilated; 3. Periodically clean the fuel system; 4. Regularly clean the radiator. The new Focus is a compact car under Changan Ford. Taking the 2021 Focus Manual Fengyue model as an example, its body dimensions are: length 4647mm, width 1810mm, height 1468mm, with a wheelbase of 2705mm. The 2021 Focus Manual Fengyue model is powered by a 1.5L naturally aspirated engine, with a maximum power of 90kw and a maximum torque of 153nm. It uses a MacPherson independent suspension at the front and a torsion beam non-independent suspension at the rear.

This topic has been widely discussed among car enthusiasts. The mechanic at the repair shop next to my house keeps saying: the Focus models from 2018 to 2019 were indeed all equipped with three-cylinder engines. The 1.5T engine was really powerful, but it shook so much during cold starts that you could balance a coin on it. Starting with the 2022 model year, got smarter—the four-cylinder 1.6L naturally aspirated version made a comeback. Last week, I accompanied a friend to the dealership for a test drive and even opened the hood to count the spark plug holes—four of them! However, the 1.5T version still maintains the three-cylinder design, so buyers should double-check the spec sheet. Honestly, three-cylinder engines aren’t that scary; they actually offer quicker power response when new. Just remember to replace the engine mounts after five years, or the steering wheel vibration will become noticeable.

As a track enthusiast, I rented a three-cylinder Focus for mountain runs last year. Honestly, the 1.5T three-cylinder is exceptionally agile in corners, with an 80kg lighter front end that makes turn-in super crisp, and fuel consumption is just over 7L/100km. But my friend's four-cylinder version is more suitable for daily driving, especially in traffic where the auto start-stop is much smoother. The latest model isn't exclusively three-cylinder anymore—the base automatic version comes with a 1.6L four-cylinder, while the sport version uses a three-cylinder + electric motor combo. Post-facelift, the engine bay layout has changed, with the filler port moved about 15cm to the left, so DIY requires extra attention.

Just picked up the 2023 Focus last month, and I went through all the dealer materials before . The current models are actually a mix: the 1.5T version retains the three-cylinder structure, while the 1.6L base model has switched back to a four-cylinder engine. The salesperson mentioned that Ford redesigned the three-cylinder's crankshaft with an offset design, reducing vibrations by 30% compared to the older models. In real-world driving, the difference isn't very noticeable, though the engine sound does get a bit harsh when you floor the throttle. Some folks in the car owner group claim that three-cylinder engines cost 30% more to maintain after five years—that’s something we’ll have to wait and see.

Recently, I noticed a phenomenon in the market: the 2019 three-cylinder Focus depreciates particularly fast, selling for 20,000 less than the Golf of the same year. Mechanic Brother Wang mentioned that these cars often have issues with the high-pressure fuel pump, and replacing the part costs around 3,000. However, cars manufactured after 2022 have been equipped with a dual-mass flywheel, significantly reducing vibrations. Nowadays, new cars are clearly differentiated—the 180 version is a four-cylinder, while the 240 version remains a three-cylinder. Personally, I recommend friends in northern regions to opt for the four-cylinder for more stable cold starts in winter.

A cousin who worked at Ford's factory revealed that the initial push for a full lineup of three-cylinder engines was to meet China's National VI-b emission standards. After the current strategy change, the production lines are divided into two: the Chengdu plant mainly produces four-cylinder versions, while Hangzhou produces three-cylinder ones. When a car, checking the nameplate is the most accurate method—the 1.5T engine block with the Ford Ecoboost logo indicates a three-cylinder, while the naturally aspirated version with 'Sigma' engraved on the side is a four-cylinder. For city commuting, a four-cylinder is sufficient and offers slightly better resale value. Last weekend, while helping a colleague inspect a car, I noticed the four-cylinder engine bay has more space, making it easier to install turbo kits later on.
