I'm reading the Mazda 3 Owner's Manual prior to taking delivery of a new Mazda 3 2.0 petrol manual (UK version). After the car is stopped via i-stop, the engine restarts automatically when you depress the clutch pedal or start to release it. The manual then says "NOTE The engine restart timing varies depending on the brake pedal depression force." What does this mean? Does the engine then start more or less quickly if you apply more brake force and what variation is there in the restart time? The engine restart always seemed pretty quick during my test drives.
