The 1988 facelift of the Renault Espace was championed by the press at the time for reducing the drag to .32. Touches like the flush mount side windows and low profile door handles do for drag reduction.

Edit: As a benchmark for the slate, according to a hyper-miler website I was looking at, a 2001 ranger has a Cd of .49

mi/kwh is highly variable based on driving style, up/down elevation, weather, etc. Any “expected” quoted value would be at best highly subjective IMHO.

I disagree to the same extent the conventional MPG ratings on a vehicle sticker is variable. it all depends on the testing. If EVs had a standardized test routine that all followed similar to the EPA's MPG, then they could be equally compared.

What's more variable is the range and also charge time as any measure of efficiency. It relates to the electronics and the battery size, but not in any way a measure of the ability to go a few miles on a single kWh. Sadly, those are the metrics manufacturers love to shout about.

Until there's a standardized miles/kWh test routine, the best I think we can do it take the manufacturer's max advertised range / advertised battery size and see how it compares to other makes and modes using the same formula. The Slate's smaller battery is rated 52.7 kWh with an expected range of 150 miles. 150 miles / 52.7 ... That's the same as ~2.8 miles/kWh.

Using that simple equation, as I originally posted, I think the SLATE should o be better considering its smallish size and supposedly lighter weight with the smaller battery option . I acknowledge that trucks aren't the most aerodynamic designs, but EVs have been improving year over year yet the brand new SLATE falls on the crappy side of miles/kWh. SLATE should do better.
