What do fuel consumption A and B mean?
2 Answers
Average fuel consumption A refers to the fuel consumption generated during the current trip, while B represents the fuel consumption per 100 kilometers. Generally, cars display the average fuel consumption, and there is a square button on the upper left side of the dashboard. Pressing this button allows you to view the car's fuel consumption. Typically, the fuel consumption per 100 kilometers is used to judge a car's fuel efficiency. Below is an introduction to Trip A and Trip B: 1. Trip A and Trip B can be freely set. For example: Trip A can be set to reset automatically after each refueling, which means it will clear and restart counting after every fuel fill-up. This is used to track the mileage and fuel consumption for each tank of fuel. Trip B can be set to reset with each vehicle start, which means it will track the mileage and fuel consumption for a single trip. 2. You can also set Trip A and B according to your preferences. By default, they are not linked to any events, meaning they will continue to accumulate the vehicle's mileage and average fuel consumption unless manually reset. For example: If the car has driven 10,000 kilometers since purchase and neither Trip A nor B has been reset, then both will display 10,000 kilometers and the average fuel consumption over that distance.
Having driven for over a decade, I understand the meanings of Fuel Consumption A and B. A usually refers to the average fuel consumption of the car, such as the average data displayed on the dashboard after you've driven a certain distance since the last refueling. B, on the other hand, is often the instantaneous fuel consumption, showing the real-time fuel consumption rate while you're driving. I frequently monitor A to assess the condition of my car—stable values indicate normal operation. When B is too high, it reminds me not to press the accelerator too hard, as it wastes fuel and harms the engine. I remember once on the highway when B suddenly spiked, I immediately slowed down and ended up saving quite a bit of money. Developing good habits like maintaining a steady speed, braking less, and regularly maintaining tires can all help keep the A value favorable. Driving isn't just about reaching your destination; it's also about learning to save fuel and protect your beloved car.
