Feel the rush and dominate the terrain on an ultra high-performance snowmobile. The 2010 Polaris 600 Rush ($10,300) is equipped to rip the snow with a 120-plus horsepower, a Liberty 600cc, liquid-cooled, horizontal in-line, 2-stroke engine and a continuously variable transmission. Other features include potential game changers like a stiffer chassis and an industry-first Pro-Ride mono-shock rear suspension that won’t bottom out.
