Those in the Eco-friendly camp will be pleased to challenge their friends without a hint of guilt about the damaging effects to the environment with this new eco-toy from Takara Tomy. The hand-crank is used not only to charge the battery in the car when connected but also to control the speed of the car while racing. Turn it faster for a speed burst or crank it backward if you get stuck in a corner to throw it in reverse. Currently scheduled for a mid-July release, the 4 available versions are modeled after the 4 most popular hybrid cars on the road today.
