I believe that’s accurate to the level possible at this time.
When in low-speed (<40 mph) traffic that’s relatively flat, you could probably bump that up to >3 miles/kWh. I get closer to 4 in the Lightning for around-town driving, and in some specialized contexts, I can get >8 miles/kWh round trip for 40+ miles.
When in high-speed (70+ mph) highway driving, they’ll probably get closer to 1.8 miles/kWh. I get an average of about 2.3 to 2.5 miles/kWh, but I also see a lot of Lightning drivers get less than I, so I don’t know all the reasons I get higher efficiency than many. I have ideas, but it’s not important at the moment.
The average will be somewhere around 2 miles/kWh. All the trucks are getting something like that. A heavier truck will perform worse in stop-and-go traffic and about the same in freeway driving.
N.B.:
0.342 kWh/mile = 2.92 miles/kWh
0.371 kWh/mile = 2.69 miles/kWh
IMPORTANT NOTE:
One should note that range divided by battery capacity is not the entire story when doing the dollar-cost per mile math.
You also have to include efficiency of transfering energy from the grid to your battery. That’s about 85-95% efficient. If you take my 2.5 miles/kWh freeway driving and multiply it by 85%, you get about 2.13 miles/kWh, which is what the EPA estimates for total efficiency. The EPA numbers for mpge for the electric trucks and SUVS give you a better understanding of total efficiency. Will Scout achieve Rivian-levels of total efficiency? I think they can. I think they can even exceed those and may achieve what
@strider estimated. But it will require some clever engineering across the board, from better surface area, better coefficient of drag, better weight, better electrical efficiencies. We’ll see.
Lightning Extended Range:
48 kWh / 100 miles = 2.1 miles/kWh
R1S (Max Pack, Dual motors):
40 kWh / 100 miles = 2.5 miles/kWh
R1T (Max Pack, Dual motors):
39 kWh / 100 miles = 2.56 miles/kWh
Chevrolet Silverado EV (Extended Range):
50 kWh / 100 miles = 2.0 miles/kWh
Kia EV9 (Long Range, AWD):
41 kWh/100 miles = 2.44 miles/kWh
