The Mach E is considered a utility/truck and in past years Ford needed to build efficient cars to offset less efficient cars. Maybe the rules have changed now so that Mach E as a BEV be used, maybe they don’t differentiate across the manufacturer’s corporate fleet now…
From that shot, if you hadn't told me it was an Acura, I would have thought it was a Tesla Model Y with a funky wrap.

2026 CAFE target for cars with that footprint is about 57 mpg
