What’s even greener than a car powered by an electric motor? A vehicle powered by no motor at all. Yes, it’s a soapbox car, popular in Northern European countries, as well as North America. Hyundai is teasing a soapbox car which was penned at the Hyundai Design Center Europe and it will soon be available for order.

In case you’re not familiar with the concept of a soapbox car, it’s essentially an engineless, motorless wheeled vehicle that you essentially roll down the road in. It relies solely on gravity to keep itself going, so it doesn’t have any source of external power.
