A specially-made steering wheel peripheral is to be released for Mario Kart 7 on the 3DS, with a surprisingly useful looking design that's made to work with the game's motion controls.
The wheel has L and R shoulder buttons built into it, but the actual steering is controlled by the 3DS's gyroscope controls. That means it'll essentially work just like using the Wii Wheel with Mario Kart Wii.

It's officially licensed by Nintendo. Sorry if it's in wrong section/similar post.
JUST SOME CLARIFICATION:
- It works exclusively for Mario Kart 7 (ONLY ONE GAME)
- It is made and initiated by Hori. Nintendo just approves it.
