What is the actual fuel consumption of the 1.4 Jetta?

The latest 1.4L Jetta has two models, including the 2019 Dream Edition 1.4L manual fashion model and manual comfort model. Both models are equipped with a 90 horsepower engine, and the NEDC comprehensive fuel consumption is 5.9L. The level of car fuel consumption is directly related to five major factors, namely driving habits, the car itself, road conditions, natural wind, and environmental temperature. The specific factors that will increase car fuel consumption are as follows: Driving habits: Rough driving, such as sudden acceleration, frequent overtaking, and not releasing the throttle in advance when encountering a red light, will increase fuel consumption. The car itself: Cars with larger displacement consume more fuel than those with smaller displacement, because larger displacement generally means greater power, requiring more gasoline to burn and do work. Cars with greater weight will have higher fuel consumption, because greater weight requires larger driving torque. Road conditions: Dirt roads, muddy roads, soft roads, mountain roads, etc. Driving on these roads with greater resistance will increase fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperature: The low temperature of the engine block makes the gasoline injected during cold starts less likely to atomize, requiring more gasoline to be injected for combustion, increasing fuel consumption. At the same time, low temperatures cause the engine computer to control the car to warm up at higher speeds, which also increases fuel consumption.
I've been driving a 1.4-liter Jetta for a while, and the real-world fuel consumption generally averages around 7 to 8 liters per 100 kilometers, but there are quite a few influencing factors. For instance, in the city with frequent traffic lights or congestion, it can go up to 9 liters; on the highway with steady driving, it can drop to around 6.5 liters. From my own experience, I've noticed that low tire pressure increases friction, which can easily raise fuel consumption—maintaining the standard pressure can save about 0.5 liters. The age of the car also affects fuel economy; if engine carbon buildup isn't cleaned in time, performance worsens, and more fuel gets burned. To measure real fuel consumption, it's best to do it yourself: fill up the tank, drive a few hundred kilometers, and then calculate the average—don't just rely on official data. After all, driving habits like frequent hard braking or aggressive acceleration can push the numbers up. Regular maintenance, such as changing the air filter, can also optimize fuel consumption and prevent small issues from becoming big problems. Overall, this car is quite economical among compact models, but it really depends on how you drive and the condition of the car.
I've been driving my Jetta for three years, and I find the real fuel consumption of the 1.4L engine quite reasonable. During daily commutes in traffic jams, it can reach around 9L/100km; on weekends driving in suburban areas, it drops to about 7L/100km. When my friend first bought a new car, the fuel consumption was relatively high for the first few months, but it improved significantly after the break-in period. Driving style really matters: frequent acceleration and braking can easily add 1L/100km. I recommend developing a habit of smooth throttle control and anticipating road conditions in advance. Additionally, using air conditioning in summer does increase fuel consumption—I've tested it, and it adds about 0.8L to 1L/100km. If you're concerned about costs, driving 1,000 kilometers a month with 92-octane gasoline would keep expenses under 600 yuan. Don't overlook regular maintenance: insufficient tire pressure or dirty engine oil can silently increase fuel consumption. I chose the Jetta mainly for its affordability, but you need to adjust your driving rhythm according to actual road conditions, otherwise even the most fuel-efficient car can become expensive.
