What does 5-speed mechanical automatic mean?

[Adaline]

It means having five gear positions like a car, with five-speed transmission. Below are relevant introductions: 1. Automatic transmission vehicles: These refer to vehicles whose transmissions can automatically shift gears based on speed to achieve optimal power matching. Automatic transmissions are categorized into continuously variable (CVT) and stepped (X-speed), with significantly different shifting principles. 2. X-speed automatic transmissions: Currently, there are mainly 4-speed, 5-speed, 6-speed, and 7-speed variants. These can be understood as simply automating the traditional 4-speed, 5-speed, 6-speed, or 7-speed manual shifting processes (though the transmission structure is much more complex). Finer gear divisions result in better power matching performance, making the vehicle more fuel-efficient and the shifting process smoother.
