Think about it a bit. Fz5 is a RR car(Engine is on the rear), it's weight balance isn't good. 
I prefer fz5 simply, because it has more power and is still very driveable. If XRT wasn't so low powered I would be driving it. Or If it at least had some things taken out from inside - so it would be lighter.
edit:
The point is - It's not the power of FZ5 that is a problem, it is its layout. Moreover, I actually wish FZ5 had more power.

 drifting is a technique and a form of motorsport and has been for years ,its also a style,and if executed correctly looks excellent,should be moulded into part of the game, obviously a new drift track would be good instead of those cones!,no extra cars are needed just user to experiment with setups diffrent types of drift (shift lock,power over,fein  etc can be achieved with minimal config ,and good control

 and the XRT should still have 9500RPM, instead of 7500
