The GXP is front wheel drive because the Bonneville was only 4 years old in it'* current configuration when it was released. The cost to redo the entire platform for rear wheel drive would have been very high, and not enough to come close to making money off of the 4000 or so units that were produced in 04 and 05 model years, GM doesn't have an all wheel drive setup that would work on this platform either.
It most certainly was not kept as front wheel drive for performance reasons. Show me one sports car (not a sporty model of a sedan) or higher that has rear wheel drive.
Personally It was a refreshening of the Bonnie to try to boost sales/image, however the model we have now should've been released instead of the SSEi in 2000 in my opinion. It'* too little and too late to compete with new cars in the segment.
