Mario Kart series
Mario Kart: Double Dash!!
In Mario Kart: Double Dash!!, it was Wario's kart of choice and could fit two people. In the manual for Double Dash!! it was mentioned that his car's top speed was 280 mph, however for the Mario Kart Grand Prix, its engine had been turned down.
The Wario Car is a heavyweight kart, which means it's heavy, tough, and speedy. However, in comparison with the other heavyweight karts, the Wario Car is lesser in weight; its weight is tied with the Turbo Birdo and Parade Kart. The car was also an unlockable kart in Mario Kart Arcade GP 2.
Unlike Wario Land 4, the Wario Car in Mario Kart Double Dash!! does not have a windshield.
