The T6 has the same READ (Rear End Accessory Drive) setup as the 3.2, they're the same basic engine. Normal engines have a FEAD (Front End Accessory Drive).
Here is a pic of the alternator on the side of the engine
There are a few interesting articles and photos of this engine online. I've had a look through a few US based forums for the LR2 (Landrover Freelander) and Volvos using this engine and they appear to be robust and reliable. I can see me owning one in either a T6 V70 or possibly a Polestar V60 in the near future.
