What is the difference between coasting in neutral and coasting in gear?

[RosalieMarie]

The specific differences between coasting in neutral and coasting in gear are as follows: 1. Operational difference: Coasting in neutral means shifting into neutral and relying on the car's inertia to move forward. Coasting in gear means remaining in gear without pressing the clutch or accelerator. 2. Fuel efficiency: When coasting in neutral, the engine may cause increased transmission wear due to poor lubrication. However, when coasting in gear, the vehicle's fuel injection decreases and gradually drops to zero. The vehicle remains in the "ignition" state, and the farther it coasts, the more fuel is saved. 3. Safety: If the car stalls suddenly while coasting in neutral, the engine, vacuum-assisted braking system, and hydraulic power steering system will stop working. This may lead to loss of control and potential accidents. In contrast, coasting in gear is safer because the car remains in the ignition state, allowing other systems to remain operational in case of emergencies, ensuring timely response and safety.
