There is a new XRAY buggy coming out tomorrow and that development did take the 'US style' tracks into account.
The name is XRAY XB808 (not sure about the XB part.....
)
The new xray was designed with US tracks in mind as the track for this years worlds is a typical US track so the new car will handle the bumps very well which is the key for a car in the US i would hang on for a bit and get the new xray.
