How do modern gas cars stop and restart their engines so easily/quickly?

279 views

I drive a slightly older (2012) truck and when I start my engine, it takes a couple seconds to for the engine to turn over. If I shut down and restarted at every red light, it would probably be annoying to drivers behind me. New cars can basically restart the instant you touch the gas. The delay is hardly noticeable. What’s different?

That type of stopping and starting requires there to be a starter that is designed to be used that many times. Regular starters would probably wear out if used that much.
