The Trax STi: car, tank or snowmobile?  US Subaru rally driver and general all-round mentalist Ken Block is back, this time with what is possibly the ultimate snow vehicle - a very much winter-ready WRX STi.

It's called the Trax STi and it started life as one of Block's open-class WRX STi rally machines, but with the power of the 2.5-litre turbocharged boxer motor tweaked to 400bhp courtesy of a tweaked Motec ECU.
