When you let off the clutch in a manual- you can feel your car slow down. It’s called engine braking! It gives you more control over your car, but how does it work? Is it friction? And how is that different from the loud rumple of a diesel Jake Brake? We get into the differences between the two, and let you know if engine braking is good or bad for your engine!
