Mach-E Highway and City range estimates from Window Sticker Label

I think it can be much simpler than that. A one-time head-to-head like that won't work when there's 5, then 8, then 12, then 20 comparable BEVs. That come out at different times.

What we really need IMO is a miles/kWh number cruising at 70 MPH at 70F with no climate control. Then another one at 70 MPH at 30F with climate control set to 70F after preheat (since heating appears to have a dramatic effect on power consumption, and thus range).

The problem is environmental factors, which is why the EPA does it inside on a dyno. To be practical you don't need a complete head to head testing of all cars every time. Start with a representative sample head-to-head, and later you can do a relative comparison with a selected yardstick (Tesla would be the logical choice). You'd need to do cold, moderate, and hot climates with all cars having the same environmental settings to get a complete picture - including retracing your route like Kyle and the other pros do. That way you account for wind and elevation as well.
