Heart Coach

History:

When Peach set out to design her own Kart for the 2003 Grand Prix she poured a tremendous amount of resources into its construction. She modeled its design after the Royal Coaches her family had used for years roaming around the Mushroom Countryside.

The Heart Coach is a Middleweight Kart, meaning that it may only be used by Mario, Luigi, Peach, Daisy, Waluigi, Yoshi, or Birdo, or any of the preceding with a Lightweight Racer.

It is ultimately a fairly average Kart, although its stats are good for a Middle Kart, including possession of the second-highest Acceleration and Offroad. The Kart has one of the slower speeds for a Middle Kart, but it is still superior to many Light Karts. It's one of the narrowest and least bouncy Middle Karts as well, and eighth in both overall. It also has the single greatest Turn Speed in the game. All in all it's a pretty decent vehicle.

The Kart appears as the Staff Ghost driven by Peach on Peach Beach and Daisy on Daisy Cruiser.

Koopa King

History:

Bowser devised his personal Kart for the 2003 Grand Prix based on his own face. He poured many resources including salvaging old tank parts from his Dark Army into creating one of the fastest and heaviest Karts on the track, a true reflection of his big bruising personality. Naturally, he named it after himself.

Double Dash:

Being a Heavy Kart, the Koopa King may only be used by any of the following drivers while paired with another racer of equal or lesser weight: Bowser, Wario, Kong, Petey Piranha, or King Boo.

The Koopa King has great speed at the expense of acceleration and Offroad, which are among the worst in the game. It is also the widest Kart, meaning it is a huge target for errant Shells, and it's difficult to dodge dropped Bananas and Fake Item Boxes. It actually has moderate Turn Speed, though, and has one of the better suspensions, due to its massive weight. It's a dastardly Kart - there are other Karts that match its impressive high speed without being absolutely terrible at everything else, such as the Green Fire or Piranha Pipes.

Bowser uses the Kart along with Bowser, Jr. in the Secret Staff Ghost Time Trials only on Bowser's Castle, because Bowser, Jr. has no Staff Ghost.

Green Fire

History:

Upon the edict that every racer would submit their own individual Kart into the 2003 Grand Prix, Luigi felt tremendous pressure to emulate the Kart of his brother, Mario. Luigi did so on the surface, but he overemphasized all of the Red Fire's specifications, nearly creating a Heavy Kart in the process. Whether or not this was a subconscious effort to side with the enemies of Mario, who were all heavyweights, is up for speculation.

The Green Fire is a Middle Kart, meaning that it may only be used by Mario, Luigi, Peach, Daisy, Waluigi, Yoshi, or Birdo, or by any Lightweight Driver paired with any of the above.

The Green Fire does act like a Heavy Kart, though. It has very high top speed and low acceleration, although its bounciness lies with other Middle Karts, and is actually a little lower than some like the Waluigi Racer. It has some pretty rough Turn Speed, but actually some moderately good Offroad for either a Middle or Heavy Kart. Its size is about average, meaning that while its profile won't take up the whole track, it's still not in the best shape to dodge incoming objects.

The Kart makes no appearances in any Time Trails, instead Luigi drives the Red Fire with Mario in his appearances. The Green Fire is a decent choice for anyone looking for a Middle Kart with some speed that acts like a Heavy Kart, but in general it has many flaws that prevent it from becoming an outstanding choice.
