The tank-like Der Ziesel Offroad Driving Machine is one of our most favorite things this year. More than capable of tearing it up on snow, sand, mud or grass, it's powered by a pair of PMS electric disc motors good for 21-hp and 30 lb-ft of torque. Expect to reach a top speed of 22 mph, all under the control of a one-handed joystick. Incredible fun.
