The best Mario Kart will soon be the fastest, as well. Nintendo has announced an upcoming update that adds a new, faster mode to the Wii U racer. Traditionally Mario Kart games offer three classes for racing, 50cc, 100cc, and 150cc. But the new update adds the fastest mode yet with a 200cc mode. It will be available as a free update on April 23rd, and should help make the craziest game in the series — which already includes features like anti-gravity race tracks — even crazier. Good luck on Rainbow Road.
