The Mighty Mini 4WD (マイティミニ四駆, Maiti Mini Yonku) series is a line-up of Mini 4WD cars introduced by Tamiya in May 1998.
It was, unfortunately, introduced during the declines of 2nd Mini 4WD boom.
Being a sister series to the Aero Mini 4WD series, the Mighty Mini 4WD cars were equipped with the large diameter wheels, namely the newly-designed Mighty-Type wheels and arched tires.
In some ways, it can be seen as the Super Mini 4WD version of the Aero Mini 4WD series.
The manga series Mini 4 kids and Future Racer V-Twin featuring cars from this line-up.
