Steel Driver

The Steel Driver is an unlockable kart that appears in Mario Kart 8. The name is based on the game Steel Diver. In fact, its Japanese and Italian names are the Steel Diver. It is a submarine-like vehicle with a dark blue top and a red underside. When the kart goes underwater, the propeller will appear in the rear guard, much like an actual submarine. The emblem is located on the sides of the kart. It has the same stats as the Badwagon, the Tri-Speeder, the Standard ATV, and the GLA. It boosts weight and traction, but lowers acceleration and handling.

In Mario Kart 8 Deluxe, it is now available from the start. In this game, it boosts speed and weight, but lowers acceleration and handling. It now shares stats with only the Tri-Speeder and Bone Rattler. CPU Iggy, Koopa Troopa, and Dry Bones are occasionally seen using this kart, paired with the Metal tires.
