What kind of car consumes 40 liters per 100 kilometers?

Ordinary family cars cannot achieve a fuel consumption of 40 liters. For standard semi-trailer trucks, under normal road conditions and standard load conditions, with a total weight of 50T, the fuel consumption per 100 kilometers ranges between 36L-45L. Currently, heavy-duty semi-trailer trucks are equipped with diesel engines. Compared to gasoline engines, diesel engines are more resistant to rough conditions, offer stronger power, are more economical, and are also safer. Differences between diesel and gasoline engines: The process of converting fuel into energy differs: A major difference between the two types of engines is how they convert fuel into energy. According to engineering explanations, gasoline engines typically use spark plugs to ignite the mixture of fuel and air in the cylinders. However, diesel engines compress air until it reaches a sufficiently high temperature to ignite the fuel once it is injected into the cylinder. To heat the air to that point, diesel engines require a particularly high compression ratio: the volume of the cylinder when the piston is at its highest point compared to when it is at its lowest point. Other aspects: Gasoline engines are quieter but have weaker power, and gasoline is more expensive. Diesel engines are noisier than gasoline engines but offer stronger power.
I remember driving an old large-displacement SUV before, with terrifyingly high fuel consumption, often over 15 liters per 100 kilometers. But 40 liters per 100 kilometers is simply outrageous—normal cars can't reach that level. This is usually an issue for large trucks, heavy-duty vehicles, or specially modified cars, possibly due to poor engine efficiency, excessive weight, or poor maintenance, which worsens the problem. Such cars are rare in the market now, as modern vehicle designs emphasize energy efficiency. Even off-road vehicles like the Hummer keep consumption around 20 liters. Driving such high-fuel-consumption cars feels like burning money—dozens of dollars per kilometer in fuel costs—making them highly impractical. I recommend prioritizing fuel-efficient models when choosing a car, as they are both economical and eco-friendly.
I've always been concerned about the cost of car fuel consumption. If a vehicle consumes 40 liters of fuel per 100 kilometers, the refueling expenses can drain your wallet as fast as running water. Such vehicles are typically large engineering trucks, supercars, or outdated buses. For instance, those luxury cars with V12 engines might approach this level during aggressive driving, but such scenarios are rare in real-life situations. High fuel consumption stems from excessive engine power output and inefficient transmission systems. In daily driving, frequent stops and starts can exacerbate fuel wastage. In contrast, ordinary SUVs or sedans generally consume between 8 to 15 liters. These extremely fuel-thirsty vehicles are only suitable for special occasions. Owning one would multiply your monthly fuel costs several times over, which is truly not cost-effective. Opting for an energy-efficient car is the wiser choice.
