Range issues

[JohnFoxeSheets]

I'm way behind on understanding all the dynamics of range so I'm starting to learn a lot from reading posts like these. That being said, I'm curious from all of you that know a lot more than I do, your reaction to the performance I had yesterday. I have an extended range AWD. I was disappointed with the lower actual range miles I got for my long drive (even with driving highway speeds) I had higher hopes. However, maybe it's my expectations that are off.

Started at 100% - 304mi
Distance - 180mi
Ending range - 66mi
2.6mi/kWh
Energy use - 2% climate, 97% driving, 2% accessories, 0% ext temperature
Accel - 98%, Decel - 97%, Speed - 25%
Ave speed - 75mph
Ext temperature - 60 degrees

Thoughts?

I haven't taken enough longer trips to have a better sense on planning and expectations for charging. Is the trip planner pretty accurate for incorporating necessary charging?

Appreciate any help on this.

As others have said, it's the speed that lowers your range. In the stats you posted, you included this: "Accel - 98%, Decel - 97%, Speed - 25%". These are Ford's estimates of how "well" you did vs. perfect driving. Anything less than 100% means you lost range. So while your Acceleration and Deceleration were quite good, it was the speed that lowered your range.

So why did the car show you a range of 304 miles when you started your trip? Because your previous driving hadn't been at 75 mph speeds for three hours straight. While it attempts to predict the future, the GOM only knows what it's seen in the past. It can't know where or how you will be driving.

One other thing: while ICE vehicles generally get better mileage on highways than in cities, with EVs it's the opposite. There are a number of factors that cause this.

I've had my car for over 2.5 years, and have the same spec Premium 4X. I average 2.7 mi/kWh for highway speeds in the summer (2.4 in winter). So at 2.6 you're in the right ballpark for 60 degree temps.

I use ABRP and PlugShare instead of the onboard nav for trip planning. But I do find the onboard nav is pretty accurate at SOC estimates since we got the updated software that adjusts the range based on the navigation destination.

I tend to agree that the onboard nav is quite accurate. I do several long trips for work a week, and it's always been pretty close. Mine's a 2023 built, so maybe the earlier ones were not that good, but I'm quite happy with it.

Basically, I'm using 10% battery for every 50km (31 miles), and that's @ 120km/h (75m/h). In summer/automn that is.
With an extended range, that's 500km on a full charge, which is great, considering my work trips are 350-400km each. Should be just enough during winter too.
Happy owner here .

You drive fast.

Your throttle technique is good.

If you want to arrive sooner on a multicharge trip, go slower. Like 65. Although it is just math, you can work out charging time vs road time. That extra 10 miles per hour does get you to a charger quicker.

I easily get 3.5 to 3.7 on the freeway, assuming flat. I have rwd is the only difference.

Haha - thanks. Yes a lot of the highways in the midwest are 65 - 70mph speed limits. Thanks for the input.

Speed is the biggest killer of range. If you have a super-far distance to the next charger and would be at the edge of your charge envelope, drive slower. If you can make the next charger with a lot of charge to spare, go ahead and drive somewhat fast. ??
