The Focus is equipped with a three-cylinder engine, each cylinder having 4 valves. Below are the dimensions of the Focus model: 1. Length: 4647mm. 2. Width: 1810mm. 3. Height: 1468mm. 4. Drive type: Front-wheel drive. 5. Comes with two engine options: 1.0T and 1.5T. 6. Uses an 8-speed automatic transmission. Below are the configurations of the Focus model: 1. Interior: The interior is relatively simple but well-crafted with good materials, providing a pleasant tactile experience. The multimedia system includes a central control screen. 2. Performance: The 1.5T engine delivers 184 horsepower, offering good high-speed stability and effective noise insulation. 3. Fuel consumption: The fuel efficiency matches the performance, with a combined fuel consumption of around 7.6. Fuel consumption is higher in congested traffic conditions.

My 2020 Focus is equipped with the 1.5T three-cylinder engine. After driving it for two and a half years, I have to admit I'm a bit conflicted. You can feel a slight steering wheel vibration during startup, though it runs quite steadily on highways. I originally bought it because it was 20,000 yuan cheaper. Now the new mild-hybrid version has significantly reduced vibrations, but dealers always use the three-cylinder issue to bargain down the price. If I were choosing a car now, I might wait for the new four-cylinder version—I heard the 2023 facelift will switch back to a four-cylinder engine.

Having worked as a salesperson at a 4S dealership for five years, the controversy surrounding the full switch to three-cylinder engines in the Focus after its generational update is quite significant. Both the 1.5L naturally aspirated and 1.5T engines feature a three-cylinder structure, with Ford specifically adding a balance shaft to counteract vibrations. The advantage of the three-cylinder setup is its city fuel consumption, which can be just over 7L, saving more than 1L compared to the older four-cylinder models. However, customers during test drives often turn off the air conditioning to listen to the idle sound. In reality, this generation's Ecoboost turbocharged engine delivers a more immediate power response than some 1.6L four-cylinder engines once the turbo kicks in.

Several issues specific to the three-cylinder Focus have been encountered. The turbo pipe is prone to oil seepage and requires regular clamp replacement, while engine mount deterioration becomes more noticeable than in four-cylinder vehicles after exceeding 80,000 kilometers. However, the simpler three-cylinder structure actually makes repairs cheaper, with spark plug replacement labor costs reduced by half an hour. The new model's addition of a BSG motor assistance has significantly improved cold-start vibrations. Owners are advised to clean the throttle body every 20,000 kilometers, which proves highly effective in vibration suppression.

Last month, my best friend struggled for a long time over the three-cylinder issue when a Focus. I accompanied her to test drive at three dealerships. The salesperson said the entire lineup now comes with a 1.5-liter three-cylinder engine, but the new model has added a 48V mild hybrid system. In actual driving, the start-stop is indeed smooth, but you can still feel the engine engaging when maneuvering in the underground garage. As for advantages, the car is exceptionally agile in corners, and the three-cylinder engine being 50kg lighter does help with handling.

Comparative testing between the Focus 3-cylinder and Civic 4-cylinder, data speaks: the 3-cylinder's turbo engages at 1400 rpm, 300 rpm earlier than the Civic, and accelerates 0.8 seconds faster to 60 km/h. However, idle noise is 2 decibels higher, and the engine mounts need replacement after three years. Ford's 3-cylinder achieves a decent 37% thermal efficiency, but domestic consumers have low acceptance of 3-cylinder engines. Rumor has it the next generation will revert to a 4-cylinder.
