Who said cars can't fly? After Hours' Scramjet definitely can, but for a hefty price of almost five million bucks. Its design is heavily borrowed from the Speed Racer anime series, and this car packs a serious punch when it hits the roads.
Besides being extremely fast, it has sensitive handling, so it'll take some time before you get used to it. More than that, it can shoot rockets and jump really high, which may result in some fantastic stunts.
