What are the techniques for coasting in neutral with an automatic transmission?
1 Answers
Cars equipped with automatic transmissions should not coast in neutral, and there are no techniques to speak of. The reasons why coasting in neutral is not recommended are as follows: 1. When a car is coasting in neutral, the connection between the engine and the drive wheels is disconnected, and the car moves forward solely by inertia. In emergency situations requiring braking, all braking force must be provided by the brakes alone. When coasting with the transmission engaged, the engine itself provides some resistance, which, combined with the brakes, shortens the braking distance. Additionally, coasting in neutral can cause the car to stall easily, leading to brake booster failure and reduced braking performance, increasing the risk of rear-end collisions. 2. If neutral coasting is chosen, the car's computer will put the engine into idle mode, and fuel injection will continue. Therefore, coasting in neutral does not save fuel; in fact, it may even increase fuel consumption.
