Born to tackle Siberia, the tundra-wise Sherp ATV is the ultimate all-terrain vehicle because it keeps moving through mud, snow, water (it floats!), and obstacles that would leave other 4x4s stranded. It was designed to survive just about anything nature can throw at it, so it keeps going even if the road doesn’t. The trade-off is that it’s powered by a Kubota-developed, 44-horsepower turbodiesel engine that limits its top speed to 25 mph. It weighs only 2,800 pounds, a figure that makes it about as heavy as a Mini Cooper, so it can be towed with relative ease.
