An ECO car is battery operated. They can run up to 50kph and the battery lasts about 4 hours before it needs to be recharged. Just plug it in to an outlet and it takes a few hours to fully recharge. There were only about 70 of these mini cars made during a special promotion. I snagged one. Keep it inside my tea room to preserve it as much as possible. Super fun to take for a spin from time to time.
