Just a couple days ago, the Agera ML was videoed climbing through the Swiss Alps in some heavy snow which looked epic. Now, thanks to YouTuber Supercars of Milan, we see it looking a lot less epic. The Koenigsegg Agera ML overheated and broke down in Milan traffic. Black smoke could be seen coming out of the exhaust as the driver tried to crank up the engine. Luckily it seems all was resolved by the end of the clip but seeing black smoke pour out an expensive machine like this is very worrying.
