What is the function of the N gear in an automatic transmission car?
2 Answers
N gear is the neutral gear, which means it does not transmit power. Here are the relevant introductions: 1. Automatic transmission car gears: P gear is the parking gear, used for long-term parking of the vehicle; R gear is the reverse gear, which is engaged when the vehicle is moving backward; N gear is the neutral gear, used when the vehicle is parked for a short time without turning off the engine; D gear is the drive gear; S gear is the sport mode, making the vehicle drive more sporty; L gear is the low gear. 2. Automatic CVT: CVT refers to a type of car transmission, also known as a continuously variable transmission. The difference between CVT and a stepped transmission is that its gear ratio is not a discontinuous point but a series of continuous values, thus achieving good fuel economy, power, and smooth driving, while also reducing emissions and costs.
In my experience driving automatic transmission cars, the N gear is essentially neutral, meaning it disconnects the engine from the drive wheels, allowing the car to stay stationary while the engine continues to run. For example, when waiting at a red light, I shift from D gear to N gear, and the car remains in place without power and won't roll away. I also often use N gear for brief stops in parking lots, as it makes it easier to start again, avoiding the need to press the brake first like when in P gear. However, never coast in N gear at high speeds, as it can easily damage the transmission. A friend of mine once made this mistake, and the repair costs were quite high. When used correctly, N gear can reduce engine load, extend transmission life, and protect the vehicle during towing. After driving for so long, I've found that understanding these small details is very helpful for safety, preventing unexpected rolling.
