It looks like SLATE has pathetic EV efficiency. (and a rant).

Apologies if this has been said. TLDR 7 pages!

The Slate is not new tech. It's allegedly proven, "off the shelf", hardware. This is a design choice when the goal is total cost and not earth shattering efficiency. Older hardware means lower range and slower charging and a lower cost.

If your goal is 0-60 times and commuting for days without charging, the Slate is not your jam.

The Slate getting ~2.8 miles per kwh wouldn't surprise me. As many others have mentioned, that's mostly a function of aerodynamics, and it's not exactly an ideal shape. That's similar to the Honda Prologue which a has a similar shaped front end at least. On the bright side, it should be less affected by external conditions, and the actual range should vary less. On something like a Lucid Air that's designed to eek out all the efficiency it can to get 5.0 mi/kwh, that drops way off once you're in anything other than ideal conditions. Whereas the big battery GMs like the Silverado and Hummer basically get 1.8 mi/kwh regardless of conditions.

If you wanted your slate to be more efficient, get the fastback top and 3d print a rounded nose cone. Then throw the pizza cutter wheels from a BMW i3 on it. You could probably push it closer to 4.0 mi/kwh like that.
