I’m on a fuel saving competition soon. There are smarts put with which everyone then drives a just 20km long distance. Now I need a few general and car related tips. Gahren is with a petrol 1.3 95ps switch transmission via boardcomputer then comes to the final bill. What is so the ideal speed range that the engine still manages well? So shortly before nibbling off? Extreme creeping (~30kmh is unfortunately not approved – just like increased air pressure) How do I best behave when it comes to a red ampel? Motor brake or still foot brake? I heard about the engine brake is not injected in the opposite to the foot brake in modern cars. I am grateful for all further tips.
