The Blue MAX (Japanese: ブルーMAX Burū Makkusu) is a pullback motor featured throughout the Choro-Q toyline. It was first introduced in 1988, in the Marathon Choro-Q sub-series. This motor features a longer mainspring than the standard Panther engine, along with a thicker, larger-diameter second gear. While its acceleration is slower, it has much better endurance. This allowed any car equipped with it to cover more distance at a consistent speed.
