[Solved] Stupid question of the day

[beders]

After resetting the EV driver history, the expected range at 100% shows 240 or so.
I was expecting 300 since I bought an extended range Mach-E.
Or so I thought.
How can I tell if actually have?

Your window sticker will tell you if you paid $5000 extra for the 88 kWh usable battery.

The quick answer: What you really have is an 88 kWh battery (usable portion). Just like you might have a 15.5 gallon gas tank in an ICE vehicle.

Beyond that, the term Your Mileage May Vary applies, quite literally. Mileage is measured as miles/kWh (MPK). And varies far more widely in a BEV than in ICE, and is greatly reduced by things like cold temps, high speed, etc.

Thanks all. I was getting a bit paranoid since the dealer initially showed me the wrong window sticker.

When I left the dealer at 100%, the range guessed 298 miles. After I reset it, I hovered around 160 for over a month. I just charged to 100% for the first time and it capped out at 302 miles so just give it some time. It should have the "EX" after the Mach E on your door also.

260 not 160!

I wonder if that is true? I'm not really sure (may well be), but it seems like there are plenty of things that can change ICE mileage. Guess I am curious if the difference is variability of mileage or just ease of refueling (ie it doesn't matter so much if you guzzle gas since it is faster to replace).

There's a little of that too (it matters far less for ICE since there's fast gas stations nearly everywhere, so we don't watch MPG as much).

But on the whole, yes, there's far more BEV MPK variability than there is ICE MPG variability. Speed makes a much bigger difference. In fact, highway mileage on ICE is usually better than city. It's just the opposite in a BEV. And not just because of regen. Speed carries a much bigger penalty in a BEV. So does temperature. And elevation change.

Temperature can affect range horribly. You can lose more than 40% of your summer range in a very cold environment.

Of course, I can put my Blazer in 4-low, deflate the tires, and kill 80% of my range, but that isn’t an environmental effect.

Good points, thanks! I am still curious about speed and how big a difference it makes between BEV and ICE, but can't seem to find a good explainer anywhere. I had completely neglected temperature. Time for someone to make a video about the relative variability of efficiency in an ICE vs BEV!

Cruising on the highway at 55 on the highway with an ICE is its sweet spot. Go 70 and MPG drops off, but is still quite good. My F-150 V8 can get 20 - 21 mpg depending on temperature and load.

Move to my Fusion Energi, a PHEV, which on the highway is basically an ICE/hybrid. The initial 21 miles of EV only is gone quickly at 70mph, and now you're a hybrid, the engine is running nearly all the time, but when you come off the gas you get some hybrid and regen. I can get high 30 mpg easily, vs. low 40s locally due to the hybrid capability. My 21 miles of EV becomes 13 in the winter. And the ICE MPG drops on local drives, because the engine has to warm up, especially to provide heat.

With the BEV, I expect to lose at least that 40% of range as stated, but hope to not live in a cold climate in the next year and lose that issue. Cruising at 70 I expect the miles per kWh to drop.

The big efficiency drop off for the Mach-E in my experience happens above 65 mph

ICE vehicles have transmissions with variable gears for low and high speeds, that is the major difference. You can run a gas or diesel engine at lower RPMs at high speeds. An electric motor with only one gear has to run much faster at high speeds.

As for weather, an ICE vehicle uses a cooling system that gets very hot, no matter what the outside temperature. So in the winter that heat gets used to warm the passengers, thus no more gas than normal. In an EV, the battery power has to be used to generate that heat. For use of AC in the summer it is a wash between the two, the ICE powers the compressor with a belt, and the EV uses a motor.
