Have you done the math to determine how efficient is the alternator is making up the extra juice?

Isn't the electric motor driving the pump weigh more than the extra pulley and couple inches of belt needed to run off the accessory belt. Thats extra weight the car has to always carry around. Just saying I just don't think the electric/hydraulic steering system is as efficient as you may think.
I would imagine the the engineers designing the WK2 did put a lot of time into doing the math and thinking of all those things before putting it into a production vehicle, although there have been some really bad ideas put into productions vehicles in the past too.

Re: Question-elect steering

I just looked at my nov build 2011 JGC to see if I had the electric pump and I did not, but I did notice that the pulley on (edit: maybe the one below) my hydraulic steering pump was stamped with "5.7L" even though I have a 3.6L. Any body else have the same thing?

Our 2012 looks similar -- not quite identical, but close enough. And yes, it is very low, down by the crankshaft. Feel isn't great, but decent by electro standards, and better than some hydraulic servo units I've used.

I was going to say this:

This means: the more electricity being used, the more drag on the engine. Less electricity, less drag on the engine. Whereas a hydraulic pump is always going to be at least a bit of a drag, increasing with engine RPM, even when not steering.
