What does 'liter' mean in Audi cars?
2 Answers
Audi cars displaying 'liter' indicates the fuel consumption per hour. Fuel consumption, as an indicator of a car's fuel economy when driving at a constant speed on good road surfaces, is widely adopted because constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure. Several key technologies related to fuel consumption: 1. Reducing vehicle weight: Reducing vehicle weight, as the relationship between weight and fuel consumption is directly proportional. It is said that for every 10% reduction in vehicle weight, fuel consumption will correspondingly decrease by several percentage points. 2. Improving car aerodynamics: Improving car aerodynamics, as a smaller drag coefficient will significantly reduce fuel consumption, and the relationship between these two is also directly proportional.
The term "liter" seen on Audi vehicles actually refers to the displacement unit of liters. For example, the numbers in Audi A4L 35TFSI do not directly indicate the liter capacity but represent the engine displacement level. Simply put, displacement is the volume of air-fuel mixture the engine cylinders can hold, and a larger number means stronger power. I once drove my friend's 2.0T Audi A6—it accelerated smoothly but wasn't aggressive. Later, I tried the 4.0T S8, and stepping on the throttle felt like being kicked—the difference was super obvious. When choosing a car, consider your needs: a 2.0L is sufficient and fuel-efficient for city driving, while 3.0L or above is better for high-speed cruising. Nowadays, Audi's new models use turbocharging technology, allowing smaller displacements to deliver higher horsepower.
