Honestly, we had a tough time including the Bugatti on this list. The Chiron has been around for a few years now, but obviously, this isn't a normal Chiron. For that matter, it's not a normal Chiron Super Sport 300+, either. Among other things, the souped-up Chiron that a select few buyers will get is limited to speeds below 300 mph. Still, this is – for all intents and purposes – a production vehicle that is capable of exceeding that insane barrier. It's also the first such production machine to do so, and for that, it's earned its place here.
