Egg 1

Egg 1 is Yoshi's original kart in Mario Kart DS. It is essentially a Yoshi Egg on wheels. The Egg 1 has above average speed, high acceleration, and high handling, but is also has low drift, weight, and items. Its name is clearly a pun on F-1 (Formula One).

It is actually one of the lightest karts, and its weight is tied with the Poltergust 4000, and the Mushmellow.

The Egg 1 reappears as a retro kart body in Mario Kart 7. It is one of the unlockable kart bodies in the game.

A similiar Kart called the Egg Rider appears in Mario Kart Arcade GP 2 and Mario Kart Arcade GP DX as Yoshi's Kart.
