One last thing on this altenator.

WTF..

Why does the RS6 use/need a different alternator than the A6,A8,A4 V8 engines? Surely the A8 loaded with all the electronic goodies requires the same alternator???

I find this very strange!!!!

Does the High Torque of the RS6 engine somehow spin the alternator any faster??? NO.
Does the High Torque of the RS6 engine somehow change rev speed that much faster than the other engines that it somehow applies a faster Rate of INCREASE Spin speed to the Alternator?
Does the RS6 engine use a different A/C compressor? A different Power Steering Pump???

What????

I bet the same alternator from any run of the mill Audi V8 would work just fine in the RS6...
