2015 VW Polo WRC Rally Car
Fresh off a somewhat dominant 2014 World Rally Championship season, Volkswagen just released their heavily modified 2015 contender. It's a 2600-pound car that hits 60 mph in less than four seconds, and is pretty much the fastest vehicle in the world on dirt—provided you're competent to handle it, that is.
Aaron Miller is the Rides editor for Supercompressor, and can be found on Twitter. He would take any one of these vehicles.
