What does WLTC combined fuel consumption mean?
3 Answers
WLTC combined fuel consumption refers to the comprehensive cycle fuel consumption value measured under the WLTP test procedure for pure fuel or hybrid light vehicles. The following are the factors that affect vehicle fuel consumption: Road conditions: When road conditions are poor, the vehicle stops and starts frequently, and the throttle and brakes are switched back and forth, which can easily increase fuel consumption. Generally, flat roads save more fuel than bumpy roads, straight roads save more fuel than curved roads, and smooth roads save more fuel than congested roads. Weather: In hot summer weather, air conditioning cooling consumes some fuel. In cold winter temperatures, gasoline does not reach the optimal combustion temperature, resulting in incomplete combustion and some fuel consumption loss.
WLTC combined fuel consumption refers to the average fuel consumption value measured under the WLTC test procedure. WLTC is a globally unified light-duty vehicle test cycle standard that is closer to real-world driving conditions than the previous NEDC. The test simulates various road conditions such as urban roads, suburbs, and highways, and calculates a comprehensive fuel consumption figure, usually expressed in liters per 100 kilometers. This testing method is more scientific because it considers daily driving situations like start-stop, acceleration, and deceleration, providing a more accurate reflection of a vehicle's actual fuel consumption. For us drivers, this means that WLTC fuel consumption data is more reliable when choosing a car, helping us roughly estimate fuel expenses and avoid being misled by exaggerated advertising claims. However, it's important to note that actual driving fuel consumption may vary slightly due to driving habits, road conditions, and weather.
When it comes to WLTC combined fuel consumption, it represents the average fuel usage of a vehicle calculated under the Worldwide Harmonized Light Vehicles Test Cycle standards. This testing is quite complex, simulating various driving scenarios such as traffic congestion or high-speed cruising, then combining them to derive a fuel consumption value, giving an idea of how much fuel the car roughly consumes. I pay special attention to this figure when buying a car because it's much more realistic than the old NEDC standard, helping me save money—if the number is lower, the fuel cost per 100 kilometers can be reduced. Don't forget that actual driving might yield slightly higher figures, so don't rely entirely on test data. Additionally, it carries some environmental significance, as cars with lower fuel consumption emit less.
