Aerodynamics are very important as speed increases. There is a formula for it, but I would have to look it up.

And the heating and cooling systems are a large drain on the batter pack.

The front end of the Mach-e looks good, but not all that slick for slicing through the air.

That could be a large part of why the miles / kWh are lower than I thought they would be.

In my Bolt in SE Florida, I can easily get 4.2 miles/kWh for all around driving if the A/C is off. Turn it on the "ECO" setting at 70 degrees and it drops to 3.6 miles/kWh.

It will be interesting to see how the numbers end up in the Mach-e

In ideal conditions at slow speeds, I expect some will report they're getting 350 on the ER RWD.

But for the opposite situation (interstate speeds + climate control + hot/cold weather), 200 might be optimistic.

We really need new, multi-level range standards (low-avg-high) for BEVs, since there's so much more variance than ICE vehicles.

In my Model 3 I see about a 20% range loss at 70+MPH. So I think we'd only lose maybe 40 miles. You are correct the variance is greater

Chevy Bolt does exactly that. It shows a low end range estimate, an average range based on previous driving, and a high end range.
