I understand bean counter profit picking,
but the regulations for EPA mpg have required buying credits or paying fines if you sell way more pickups and SUVs than small cars.
Tesla now makes eye popping money from selling credits.

If automakers are willing to pay for powered grille shutters to gain a fraction of an MPG on the “Highway” portion of the test at 55 mph,
they would pay for a windage tray even if the gain was only 0.1

I am also thinking of how that Chrysler was willing to change the tapered roller bearing to ball bearings in the 9.25 differential for a tiny gain.

Ricardo Engineering brags about their engine computer model’s ability to tweak engine design.
I wonder if that computer model could run thousands of variations of windage tray design to “evolve” one that works even slightly better.

Has any Hemi 5.7 V8 had a windage tray?

Do any Pentastar V6s have a windage tray?
