2022 RWD here, stock MXM4's, max psi, UPF front lip and rear spoiler. I show 214 Wh/mi for the last 16k miles, of which 10k of those miles had both the UPF mods. Routinely seeing under 200 Wh/mi for trips (mainly freeway). I'm easy on the pedals, but tend to be passing everyone else on the freeway. Will be interesting to see if the iON EVO AS tires bring it down further.
Lifetime is 223 Wh/mi, and that includes a 7k mile cross country trip that was pretty spirited (UPF front was installed, but not the rear).
BTW - I think weather conditions play a big part here. I'm in San Jose, CA, so consistently pretty mild temps. The RWD is going to of course be more efficient than the P or AWD. Aside from driving style, I can also say the UPF mods made a noticeable difference. Looking forward to seeing what these new tires can do.
