不是靠直接充電省錢 - ChatGPT的答案

Hybrid cars save gas through a combination of technologies and driving strategies:

1. Regenerative braking: Hybrids utilize regenerative braking systems that capture energy from braking and store it in the battery. This energy is then used to power the vehicle, reducing the need for gasoline.

2. Electric motor assistance: Hybrid cars have both an internal combustion engine and an electric motor. The electric motor can assist the engine during acceleration, reducing the workload on the engine and therefore the amount of fuel needed.

3. Engine shutdown: Many hybrids feature engine shutdown technology, which turns off the gasoline engine when the vehicle comes to a stop, such as at traffic lights. This reduces fuel consumption during idle periods.

4. Start-stop technology: In addition to shutting down the engine during idle, hybrids often use start-stop technology to temporarily shut off the engine when the vehicle is stopped, further saving fuel.

5. Optimized engine operation: Hybrid systems often include advanced control systems that optimize the operation of the gasoline engine for maximum efficiency, such as shutting off cylinders when they're not needed or running the engine at its most efficient speed.

6. Battery power: Hybrid cars can run on electric power alone at low speeds or for short distances, reducing or eliminating the need for gasoline during those times.

7. Aerodynamics and weight reduction: Many hybrid models are designed with aerodynamics in mind and use lightweight materials to reduce drag and weight, which improves fuel efficiency.
