Egg 1

The Egg 1 is a kart in the Mario Kart series. It is a 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. The emblem is located on the front of the kart. Its name is a pun on F-1 (Formula One).

Mario Kart DS
In Mario Kart DS, the Egg 1 appears as Yoshi's main kart, with above average speed, high acceleration, and high handling, but also has low drift, weight, and items. 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.

The kart is unlocked for Daisy and R.O.B. as well when the player gets gold trophies in all Nitro or Retro Courses in 150cc, and becomes available for everyone else when gold trophies are obtained in every cup in Mirror Mode.

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 tires makes it resemble the original Mario Kart DS version.

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

Mario Kart Tour
The Egg 1 appears in Mario Kart Tour, where it is classified as a Super kart. Mini-Turbos last longer and yield more points when using this kart. It uses the Roller tires, being a mix of their appearances from Mario Kart 7 (black tire treads) and Mario Kart 8 and Mario Kart 8 Deluxe (yellow center). A variant of the Egg 1, the Gold Egg, appears in the Cooking Tour, which is classified as a High-End kart.

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