Honda Power Unit Hardware & Software

[AR3-GP]

Any reason why Honda stick to A2A intercoolers unlike Mercedes or Ferrari?

Guessing same reason as Red Bull - weight and packaging. A2A intercoolers are lighter and can be mounted higher up which lets you shrink the sidepod intakes.

Cooling is not a PU thing, It's a chassis thing. PU tell the chassis how much cooling they need a chassis delivers...or suffers.

A well functioning team will communicate in both directions. Chasing outright power (+weight, +cooling) at the expense of aero can be a negative as much as chasing aero at the expensive of PU reliability. There is a sweet spot.

Naturally in a WORKS TEAM there is communication with regards to cooling but "WORKS TEAMS" are a minority in F1. Williams will have just been told the cooling requirements and go figure it out. My point was the manufacturing, placement and choice of radiators are done by the chassis team. Williams does not receive radiators with the purchase of the PU.
