Fascinating.
It's not so much a redundant HE as they're plumbed in parallel.
It looks like more of an attempt to optimize utilization of frontal area airflow.
Glancing through the bumper of the M6, I think it may have essentially the same setup (with respect to the IC HE's in the nose).
System capacity is 4L.
Thanks for posting (or re-posting).
EDIT: Read the 63tu engine detail, it actually uses THREE cores to cool the fluid which cools the intake air charge. The s55 engine detail indicates system fluid capacity and system heat dissipation. The 63tu detail does not. It is likely based on what I've read that the 63tu system has the ability to dissipate more heat the the system on the s55. Perhaps more important and unclear at this point is system heat dissipation relative to power (heat) production i.e. which system has more head room.
