[QUOTE="AustinSN, post: 15504905, member: 159453"] There is, it's very small. Think of it like a Focus ST up front with more power, the PTU (power transfer) sends power towards the rear via drive shaft and the RDU (rear drive) decides how much power it wants and where it wants to put it. The front is an open diff and it uses the brakes for torque vectoring, which isn't really needed because the rear end does so much. The markets say it can push 70% of the power to the rear, but the engineers say it can theoretically send 100% to the rear, but they have only seen as high as 95% in testing. It actually averages about 70% of the power going to the rear. Only in very light, constant speed situations will it disconnect the RDU and run FWD. It takes a lot more than we expected. [/QUOTE]
