Is it accurate for the full-tank range to increase from 550 to 800?

Range is adjusted based on instantaneous fuel consumption. Fluctuations are normal. Introduction to fuel consumption: Generally refers to the amount of gasoline consumed per 100 kilometers, which is a theoretical indicator for vehicles. Methods to reduce fuel consumption: Longer idling time leads to higher fuel consumption, so minimize idling time; also avoid rapid acceleration, slamming the gas pedal, and driving at low RPMs. Factors affecting fuel consumption: Various driving conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, temperature, and whether the air conditioning is on, all affect vehicle fuel consumption.
I always enjoy observing these numerical changes while driving. That time when I filled up the tank and the range jumped from 550 to 800, it was quite a pleasant surprise at first. The mechanism behind this is that the car's computer estimates the range based on average fuel consumption and tank capacity. If you've been driving mostly on highways or smooth roads before refueling, the average fuel consumption would be lower, resulting in a higher range estimate after filling up. Like last year after a long-distance trip, my estimated range skyrocketed after refueling, but then shrank significantly once I returned to city driving with frequent traffic lights accelerating fuel consumption. In practical use, don't take these estimates too seriously - the computer's prediction is based on data from the past few dozen kilometers and may not be accurate. It's better to leave some margin for traffic jams or air conditioning usage. Combining your own experience when planning is safer. Personally, I never rely solely on the displayed value for long trips - I always refuel in advance.
