Fuel consumption cannot be simply determined by engine displacement; road conditions are the most important factor, followed by driving habits, load conditions, vehicle weight, engine and transmission specifications, and other aspects. Below is an introduction related to automobile engine displacement: 1. Displacement and automobiles: The volume of space that a piston moves from the top dead center to the bottom dead center is called the cylinder displacement. If an engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, which represents the size of the engine more accurately than cylinder bore and number of cylinders. Many indicators of the engine are closely related to displacement. 2. Displacement classification: In China, the classification of passenger cars is determined by the size of the displacement. The displacement of a mini car is less than or equal to 1.0L; the displacement of a compact car is in the range of 1.0–1.6L; the displacement of a mid-size car is in the range of 1.6–2.5L; the displacement of an executive car is in the range of 2.5–4.0L; and the displacement of a luxury car is greater than 4.0L.

I've driven a 5.0L SUV, and fuel consumption really can't be generalized. In city driving, it usually ranges from 15 to 20 liters per 100 kilometers, while on highways it drops to around 10-15 liters – it largely depends on driving style. I've experienced fuel consumption spikes during traffic jams; heavier footwork or using AC immediately burns more fuel. I usually try to maintain steady speeds and avoid sudden braking, and have used eco mode to save some money. Some newer models with turbo or mild hybrid tech can keep it around 13L, while older versions may consume more. But honestly, driving high-displacement cars is about enjoying the power – you pay the price of higher fuel consumption for that exhilarating acceleration. Spending hundreds more on gas weekly becomes routine, so road conditions and budget should be carefully considered when choosing a vehicle.

Large-displacement vehicles tend to have higher fuel consumption. A 5.0L engine typically consumes between 12 to 18 liters per 100 kilometers, depending on the vehicle model and usage conditions. In my daily driving of a 5.0L sedan, I've observed that fuel consumption easily exceeds 16 liters in city traffic with frequent stop-and-go situations, while highway cruising maintains a stable rate around 10 liters. Multiple factors influence this, such as excessive vehicle weight increasing fuel intake, reduced efficiency in older engines, and clogged air filters or underinflated tires leading to additional fuel consumption. Developing habits like weekly tire pressure checks and oil changes can save 1 to 2 liters. Additionally, driving style plays a crucial role - aggressive acceleration and braking drivers should try smoother starts.

The large-displacement 5.0L engine is quite fuel-consuming, typically ranging from 14 to 20 liters per 100 kilometers, especially in city driving which is particularly fuel-intensive. I've seen my friend's car record over 18 liters, which is directly related to driving conditions. To reduce fuel consumption, drive steadily in daily use, avoid frequent short-distance starts, and regularly clean the fuel injectors to maintain good condition. Newer technology vehicles might perform better in optimizing fuel efficiency.
