How fast can an automatic transmission M1/M2 go?

[EllianaDella]

The maximum speed can reach 40 km/h. Here are the specific details: 1. M1/M2 speeds: 1st gear: Used for normal starting or climbing very steep slopes. The speed in this gear is generally around 10 km/h. 2nd gear: A transitional gear for acceleration after starting, or for low-speed driving or climbing steep slopes. The speed in this gear is generally around 20 km/h. 3rd gear: Used when the speed is between 20 to 40 km/h, commonly used for city driving. 2. Additional information: D (Drive): This is the most frequently used gear. P (Park): Used when parking the vehicle. N (Neutral): Rarely used, typically employed when waiting at traffic lights. R (Reverse): The vehicle is equipped with a rearview camera; when shifting to R gear, the image will appear on the central control screen, etc.

How fast can you drive in manual mode's M1 and M2 gears with an automatic transmission? In my experience, it depends on the vehicle model and engine configuration. The M1 gear is equivalent to first gear, generally reaching a maximum speed of about 30-50 km/h. For example, a compact car might struggle beyond 40 km/h, with the engine revving too high and making a loud noise. The M2 gear allows slightly higher speeds, ranging from 50 to 80 km/h. A large SUV might approach 70 km/h, but once the tachometer enters the red zone, you should shift up promptly to avoid engine damage. Actually, using M1 for low-speed hill climbing provides good traction control, while using it at high speeds only increases noise and fuel consumption. I always remind myself to watch the RPM and avoid exceeding limits—protecting engine longevity is what really matters.

As someone who loves tinkering with cars, I've tested the performance of several vehicles in manual mode. The speed limit in M1 gear is around 35-45 km/h, while M2 can reach approximately 60-75 km/h—it largely depends on engine size. Smaller displacement vehicles may only reach around 30 km/h in M1, whereas larger engines can approach 50 km/h. But that's not the main point. The issue is that driving at low gears with high RPM results in significant vibration and higher fuel consumption. I usually only switch to manual mode when slowing down on snowy roads or steep slopes—on highways, sticking to D mode is much more convenient. Speed values are just a reference; safe driving is what truly matters.

I was curious about this when I first started driving an automatic car. The instructor taught me that in M1 gear, you should only go up to about 40 km/h, and M2 around 70 km/h max, but it's always best to check the manual instead of guessing. Going too fast makes the engine sound noisy, and the steering wheel starts to shake—I once tried accelerating to 60 in M2 and immediately felt something was off, so I quickly shifted gears. Different cars have different speed limits, and my new electric car has a bit more leeway in lower gears. Anyway, don’t expect to use it for high-speed driving; it’s mainly useful for controlling uphill and downhill slopes.
