TopGear recently published a Focus RS review by Sam Philip. He didn't get to drive it but he was able to sit in the passenger side while in Drift mode and according to him, it'll "stay sideways until you run out of talent, tarmac or tyre tread" while in Drift mode.
While it's mostly marketed as a drifting vehicle, the Focus RS is still quick in acceleration and it’ll do 0-60mph in 4.4 seconds
with around 70% of the torque going to the rear
when in normal drive mode.
He goes into a lot more detail about it here
Not quite sure what means when he stated that the Focus RS sounds "Fruity".
