Since 2014, F1 engines have been subject to a strict fuel flow limit: a maximum of 100 kilograms per hour during the race. That means teams can’t just pour fuel into the engine like it’s a barbecue on full blast — they have to manage performance with precision. It’s one of the key restrictions that makes modern power units such complicated beasts. Go over the limit? You get disqualified, as Red Bull learned the hard way in Australia 2014. Fast is good, but fast within limits is the name of the hybrid game.
