Hail to the superkart! It leaves a standard sports car like the Mazda Miata in the dust,
and even a muscle car like the Corvette, with its beefy hp and flashy top speed, is a
pokey 25 seconds slower per lap. The superlight superkart (just 462 pounds) accelerates
faster than the Corvette and is nimbler in the curves. The Champ car bests the kart, but
there's no shame in that: It costs 20 times more and requires an entire support crew.
