Famitsu's report claims that the racer will include 32 courses, split evenly between new additions and remakes of classic courses, according to an IGN translation. Some of these stages will be built around mid-air tricks, a new feature for both karts and bikes that net you a boost in speed when you successfully nail a stunt.

Similar to several Nintendo first-party releases, Mario Kart Wii will allow players to bring their Miis into the game and ride a bike or kart, but the exact implementation of this is yet uncertain.

Beyond the previously announced 12-player online multiplayer, Mario Kart Wii's network functionality will feature downloadable ghost data, allowing gamers to race against the world's top players. Nintendo is also planning on implementing a Mario Kart Channel in the Wii dashboard interface which will operate in a yet unspecified way.

Mario Kart Wii will come bundled with a wheel controller shell for the Wii Remote, and supports motion-based as well as traditional controls. The game is currently scheduled for a worldwide spring release, but Nintendo has not specified an exact date for any territory.
