What is the M gear in an automatic transmission car?
1 Answers
Automatic transmission car gear M is the manual mode gear. The M gear is generally found in cars with a manual-automatic transmission, where the gear lever needs to be manually shifted to change the gear engagement position inside the transmission, altering the gear ratio to achieve the purpose of shifting. Proper use of the M gear can provide sufficient power and a sense of control while driving. Scenarios for using the M gear: 1. Downshifting: When overtaking, if the gear is in D (Drive), the speed will not increase rapidly by pressing the accelerator hard, as it still shifts up sequentially, resulting in a slower response time. If switched to M gear, the driver can press the accelerator, and the vehicle can utilize the high torque of a lower gear to accelerate instantly, completing the overtaking maneuver more quickly, saving time and making overtaking safer; 2. Descending a slope: When an automatic transmission car is going down a long slope, the speed will continuously increase, requiring the use of brakes to control the speed. However, using the M gear to employ engine braking to reduce speed is safer and also prevents wear on the transmission; 3. Ascending a slope: When the vehicle is going uphill, traffic jams may occur. If driving a manual-automatic transmission vehicle, the gear can be kept in 1st gear.
