Egg 1

Egg 1 is Yoshi's main kart in Mario Kart DS. It is a bumper-car in the shape of a Yoshi Egg with small wheels, dual exhaust pipes, and a small compartment for the driver. The lower front part of the kart suggest that it may be built using the chassis of the classic Pipe Frame karts featured in earlier Mario Kart games.

Mario Kart DS
In Mario Kart DS, the Egg 1 has above average speed, high acceleration, and high handling, but also has low drift, weight, and items. Its name is a pun on F-1 (Formula One). It is one of the lightest karts, and its weight is tied with the Mushmellow. This kart is available from the start of the game.

Much like the Dry Bomber, the kart is notable for its powerful Mini-Turbo boost. A hidden in-game statistics shows that Egg 1 has the second-highest Mini-Turbo stat in the game, only behind the Dry Bomber. Combined with its low drift stat, Egg 1 is often utilized by players to pull off the "Snaking" technique.

Mario Kart 7
The Egg 1 reappears as a retro kart body in Mario Kart 7. It is one of the unlockable kart bodies in the game, and it offers an acceleration boost, at the expense of speed and weight. In fact, the Egg 1 is tied with the Birthday Girl and Bumble V for having the highest acceleration of all kart bodies.

In terms of its hidden stats, the Egg 1 offers one of the fastest sea speed stats (tied with the Tiny Tug) in the game, making it pretty effective for underwater racing.

Equipping the Egg 1 with Roller and the Slim tires will resemble the original Mario Kart DS version.

CPUs Princess Peach and Wario can sometimes be seen driving in this body.

Yoshi can sometimes be seeing driving in this body with the Roller and the Wooden tires.

Koopa Troopa can sometimes be driving in this body with the Slim and the Wooden tires.

Daisy can sometimes be driving in this body with the Slim tires.

Donkey Kong can sometimes be driving in this body with the Sponge tires.

The Mario Kart 7 incarnation of the Egg 1 also appears as a trophy in Super Smash Bros. for Nintendo 3DS, driven by Yoshi.
