The MC20 is the rarest thing on this page, and that is the point. Maserati builds a fraction of the volume Ferrari and Lamborghini do, so this is a mid engine supercar with butterfly doors and a carbon fiber tub that almost nobody watching has seen in person. The Nettuno V6 makes 621 horsepower using pre chamber combustion technology developed for Formula 1, and at roughly 3,300 pounds the MC20 is lighter than most of what it races.
