1.4L engine consumes approximately 6-7 liters per 100 kilometers. Below is relevant information about vehicle fuel consumption: 1. Fuel Consumption Introduction: Constant-speed fuel consumption refers to the fuel economy indicator when a vehicle travels at a constant speed on good road conditions. Since constant-speed driving is a basic operating condition for vehicles on highways, and this type of fuel consumption is easy to measure, it is widely adopted. 2. Factors Affecting Fuel Consumption: There are many factors that influence fuel consumption, not only the powertrain of the engine but also the transmission, drag coefficient, body weight, and tires. Additionally, driving habits, vehicle condition, and road conditions are also very important.

I've been driving a 1.4L displacement car for over a decade, with average fuel consumption fluctuating between 7 to 9 liters per 100 kilometers. In congested urban areas, it can spike above 10 liters, while dropping back to around 6 liters on fuel-efficient highway drives. Actual consumption depends on specific models – compact cars like the Polo tend to be lower at approximately 6.5L, whereas SUVs are slightly higher around 8.5L. Driving habits are crucial too: smooth acceleration and minimal braking conserve fuel, whereas frequent aggressive throttle inputs significantly increase consumption. I recommend regularly monitoring the onboard computer display, checking tire pressure and engine oil periodically to maintain optimal vehicle efficiency.

From a technical perspective, there are multiple factors affecting the fuel consumption of a 1.4L displacement car: engine type such as turbocharging can reduce it to around 6L, while naturally aspirated engines may exceed 8L; vehicle weight and aerodynamic drag are also variables, with heavier cars experiencing increased fuel consumption at high speeds due to wind resistance, making lighter cars more efficient; daily driving conditions like using air conditioning or carrying cargo can increase consumption by 10%-15%. Reference data shows compact cars have an official rating of 6-8L/100km, but actual consumption often fluctuates around 8L. Testing methods are straightforward: record the distance covered on a full tank and calculate, or use an app for tracking, and refer to real-world test shares from car owner forums.

A 1.4L displacement car's fuel consumption is considered highly efficient by today's standards, saving significantly compared to older models. I recall older cars often consuming 10L, while new technologies have reduced this by 30%. For example, the Volkswagen 1.4TSI engine maintains a steady 6.5L on highways; 7-8L is common for city commuting, especially during traffic jams. Vehicle type selection is also crucial, as sedan models are generally more economical than SUVs or MPVs. It's advisable to check the official WLTP test report when purchasing a car as a baseline reference, since actual values can vary due to changing road conditions.
