Which is more fuel-efficient, E gear or P gear?

It can be adjusted according to different load conditions to regulate the engine output torque, thereby reducing fuel consumption. The details are as follows: E gear: This is the economy gear, which is more suitable when the truck is unloaded or lightly loaded. It does not require the engine to output full power, achieving economic fuel savings. B gear: This is the standard gear, suitable for trucks under half-load or general load conditions, allowing the truck to maintain a balance between power and economy. P gear: This is the power gear, suitable for trucks under heavy load or climbing, when maximum power output is required to ensure the truck's performance.
I've been driving my own car around a lot and found that the E mode (usually called Economy mode) is indeed more fuel-efficient than the regular D mode. The P mode is for parking and doesn't consume any fuel or very little, so comparing its fuel efficiency is meaningless. When actually driving, the D mode is suitable for quick acceleration and overtaking, but pressing the throttle harder burns fuel rapidly. Switching to E mode slows down the throttle response, making acceleration less aggressive, but it automatically optimizes engine performance—like shifting up earlier or downshifting less—to keep RPMs more stable, saving up to 10% on fuel costs even in city traffic. I tested it myself: using E mode for my weekly commute saved me 30 yuan in fuel expenses, which is both economical and reassuring. Of course, it's also important to pair it with good driving habits, like avoiding sudden braking, where E mode helps a lot.
