I visited TMW OFFROAD yesterday and got a look at the first ever RZR XP4 900. Its a 4 seat version of the all new RZR XP 900. It was way faster than the 2011 800 4 seater, it was even within a 1/2 a car of a high boost MCX turbo 4 seater. This thing power slides on asphalt, and isn't much slower than the 2 seater. Im having mine built as of today!!
