The average fuel consumption of the Focus 1.8 is 9.1 liters per 100 kilometers. The following is the relevant introduction of the 2021 Focus: 1. Body dimensions: The car has a length, width, and height of 4647/1810/1468 mm, with a wheelbase of 2705 mm. The side profile features a dynamic design style, showcasing a strong sense of power. 2. Configuration: The Focus is equipped with five safety features including rear parking radar, front side airbags, and front/rear head airbags. Additionally, the car comes with fourteen comfort and convenience features such as an electric sunroof, keyless start system, and auto hold. 3. Power: The Focus is equipped with a 1.5T-L3 engine, delivering a maximum power of 174 horsepower and a peak torque of 243 N·m. It is paired with an automatic transmission (AT), with a combined fuel consumption of 5.5L/100km as per the Ministry of Industry and Information Technology.

My old 1.8L manual transmission Ford Focus has been driven for five years, with the displayed urban commuting fuel consumption generally around 9-10L/100km. In severe traffic jams, it can go up to 12L/100km at most. It's much more fuel-efficient on highways, maintaining a steady 90km/h can bring it down to 6.5L/100km. I think manual transmission saves about 0.5L compared to automatic. Also, maintenance is crucial - once when the spark plugs needed replacement but weren't changed, fuel consumption suddenly increased by over 1L. Using AC in summer adds at least 1L/100km, and keeping the trunk constantly loaded with tools also increases fuel consumption. With a 55L fuel tank, a full tank can cover just over 500km, and my monthly commuting fuel cost is about 800 yuan.

I drove my friend's 2009 1.8L Focus automatic, which typically consumes 10-11 liters per 100km in the city and around 7 liters on the highway. The most annoying part was watching the fuel consumption spike at red lights. Later, I adjusted my driving habits by avoiding sudden acceleration and coasting more, which helped bring my average down to 9.5 liters. There was a time when my fuel consumption suddenly increased, and after checking, I found it was due to low tire pressure. The engine is a bit outdated, so it naturally consumes more fuel compared to newer models, but the chassis is exceptionally sturdy, making it very stable when cornering—worth the extra fuel consumption in my opinion. I recommend not overloading the trunk, as every extra 50kg can cost you half a tank more per month.

Actual tests show the 1.8L Focus's fuel consumption varies greatly with road conditions. Pure city driving during rush hours can reach 12L/100km, while suburban open roads drop to 8.5L. Last time cruising at 70km/h on provincial highways, the display showed only 6.8L. Winter/summer consumption is 1L higher than spring/autumn, and AC compressor usage increases fuel use by 10%. After 50,000km, consumption slightly increased, but replacing air filter and engine oil immediately reduced it by 0.8L. Don't chase cheap gas - low-quality fuel worsens combustion efficiency. Overall, around 9L/100km is typical for this decade-old engine technology.
