Unexpectedly low range

[rdr854]

To get 2.7, you must do a lot of low speed driving.

After 16,368 miles, my average is still 2.7 miles per kwh.

I just finished a trip from Northern Virginia down to Richmond. With the ambient temperature in the 80s, I got 2.8 miles per kwh going down and coming back. For both trips, I had the AC running and set to 79 degrees on the driver's side and 78 degrees on the passenger side. I started the trip with 100 percent SOC and 367 miles on the GOM and 79 percent SOC and 276 miles on the GOM when I arrived in Richmond. While we drove around Richmond a little bit, by the time we got back home, we were down to 47 percent SOC and 153 miles range left on the GOM. By my estimate, my correct range at 2.8 miles per kwh should translate to 366.8 miles of range, assuming a 100 percent charge. At 80 percent, my average range (assuming 2.7 miles per kwh) should be 282.96 miles.

Again, I do not do anything special, except that I do not exceed 65 mph, and generally try to drive 55 or 60 mph on the highway if safe to do so. I also minimize my air conditioning.

Please let me know if my math is wrong.

Forgot to add the pictures:

For the trip to Richmond, I preconditioned for the trip down, but did not do so for the trip back.

staying below 65 helps. on a recent trip I experimented from the "THIS TRIP" screen driving 75 (temp was 80) flat ground I was getting 2.1kw/m. Slowing down to 65 for about 20 miles I saw it increase to 2.3kw/m. I suspect that at 55-60 it might be 2.5kw/m.

Also: I didn't read through all 9 pages of posts, but the original poster said he had his tires pumped to 42psi. Fords recommendation is 36psi. not sure if that makes much of a difference but I thought it worth mentioning

One of the recommendations here was to increase the tire pressure so I gave it a shot. It didnt help. I wish I could get better range, but theres a 0% chance of driving slower. 70 is already too slow. At least the warmer weather has me up to 1.8, which still seems lower than what everyone else is getting.

My door sticker says 42 PSI. I think it depends on model, equipment and make/size of tires that determine the recommended tire pressure.

My 18" spare is recommended at 36 PSI.

from my 23 Lariat ER

Well that is interesting.

Mine '23 Lariat ER (Oct 23 build)came with Goodyear Wrangler Territory 2T All Season tires.

I notice my Combined weight of Occupants & cargo is rated higher than yours ,1807 lbs v 1546 lbs.

Not sure if that is just because of the tire rating of 116T.

It varies, but I figured I had nothing to lose and it's easy enough to change. The increased pressure did make for a rougher ride though. I still havent replaced the tires either, the all seasons are awful for anything other than pavement. I use it like a truck, so those need to go before I get stuck someplace I cant get out of.

Tire specific

There was a period of time that 23's were only coming with AT tire due to lack of supply, I wondered if the factory put on appropriate tire placards for the affected trucks.

That is exactly what you do special. I drive 73 in a 70 zone. I drive 3 to 5 miles over the speed limit up to 75mph.

There is no preconditioning in the 80s.
