The Hot Rod Furious Mouse car model has dual engine functionality: you can wind the spring motor by giving six full rotations of the ratchet key located on the model car's undercarriage, or you can simply pull the Hot Rod back along a flat surface then release and watch the car speed off, as you would with any pullback toy car. Turn the front wheels of your Hot Rod left or right to make graceful turns, or race down the straightaway. Other details in the Ugears Hot Rod Furious Mouse include realistic scaling, wonderful detailing on engine and interiors, and twin doors with lock and handle mechanism.
