Steel Driver

The Steel Driver is a kart in the Mario Kart series. Its name is based on the Nintendo 3DS game . 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 appears in the rear guard, much like an actual submarine. The emblem is located on the sides of the kart.

Mario Kart 8 / Mario Kart 8 Deluxe
The Steel Driver debuts in Mario Kart 8 as an unlockable kart body. 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.

Mario Kart Tour
The Steel Driver returns in Mario Kart Tour, where it is classified as a High-End kart and uses the Pirate Sushi Racer's tires. It was added at the start of the Mario vs. Luigi Tour and became the signature kart of Penguin Luigi in the Snow Tour. The kart increases the duration of Slipstream boosts and the amount of points earned for performing Slipstreams. In this game, the exhaust flames shoot out from the rear guard instead of the tailpipes.

Since introduced in the Mario vs. Luigi Tour, the Steel Driver has appeared in regular tour pipes. In its debut tour, it was also available in the Penguin Luigi Pack from November 25, 2020 to December 2, 2020.
