Is Coasting in Neutral Gear Good for Cars?
2 Answers
Coasting in neutral gear is not recommended, as it not only fails to achieve fuel savings but also causes significant wear to components such as the clutch and gears. Most importantly, coasting in neutral poses considerable safety risks. Here are the relevant details: Coasting in neutral is discouraged primarily due to safety concerns. When the gearshift is placed in neutral for coasting, the drive wheels lose traction, and the connection between the engine and the drive wheels is severed. The vehicle then relies solely on its own inertia to move forward. In the event of an emergency requiring braking, all braking force must be provided by the braking system alone. This demands that the brakes generate substantial force within a very short time, but the braking system has limited capacity. Consequently, this will inevitably affect braking performance, at the very least increasing the stopping distance.
As a veteran driver with decades of experience, I used to coast in neutral when I was younger, thinking it could save some fuel costs. However, after experiencing a few terrifying moments of losing control while descending slopes, I completely changed my perspective. The biggest issue with coasting in neutral is the loss of engine braking, which increases the vehicle's inertia, forcing you to rely solely on the brakes to slow down. This can lead to overheating, excessive wear, or even brake failure, significantly impacting control. Most modern cars are equipped with fuel injection systems that can cut off or reduce fuel supply when coasting in gear, making it more fuel-efficient than idling in neutral. From both cost and safety perspectives, coasting in neutral is simply not worth it. I strongly advise against it in daily driving, especially on mountain roads or highways. I'd rather spend a bit more on fuel for a safer driving experience.
