High speed fuel economy

Can't wait to get an Aptera and be around 300 mpg-e...

I feel the best way to compare a BEV to an ICE is to figure the cost to power the vehicle say 100 miles. This also works well for unleaded vs diesel. Sure diesel often gets better mpg, but around here unleaded is 20% less cost wise. My car also is great at using the low octane unleaded.

So then with electricity rates, for a highway trip you would have to consider the fast charger higher rates although on my example, a 240 mile each direction, you might be okay on your less expensive home rates.

So in my example I was $9.30 to go 100 miles at an average of 80mph (75-85mph)
My brothers EV6 would probably cost about $10.50 to go 100 miles using Walmart fast charging and $4 to go 100 miles charging at his home

holy moly thats expensive for 100 miles. my car costs about 8 bucks to go 100 miles on the highway. and its just a basic hybrid. no plug in or ev or anything

EVs also average about 3-4 cpm less to maintain so even if you're paying high fast-charging rates the EV probably comes out ahead.

But if you value your time at minimum wage ($15 here), it costs another 1-2 cpm in time waiting to recharge vs pumping gasoline.

And then if you value the cleanliness of energy extraction, transportation, and use you probably have to give that advantage to EVs even with the nastiness involved in manufacturing batteries & burning coal.

And those costs were at 80 mph, it would be much less around town or at slower highway speeds.

In the context of the 'average' motorist, you're only going to do a few holiday road trips, and one 'vacation' a year.
Most charging will / can be from home.
'AOC's' BOLT is averaging over 130-mpg'e.
A one-time expense for off-peak, net metering hardware sets one up for, 5-cents/ kWh. Or $1.87/gallon-e, in April, 2022 dollars. That's 1.43-cents / mile.
Not a bad hat-trick.

That’s the main reason I couldn’t get an ev. Def not the average motorist. I drive about 50,000 miles a year and do road trips every month that clock in a few thousand miles. I can’t stop to charge every few hours of driving. Would drive me insane

If we can check off all possible scenarios, you'll be good-to-go dialing in your hardware.
Best we make all mistakes on 'pixels' rather than with your bank account.

Yeah hence the aero mods for high speed driving. The car gets amazing mpg hypermiling around town. But once I hit that wide open interstate in Utah, Idaho, New Mexico and Texas, that mpg CRASHES!

Yeah, you're a very good candidate for aero.
The velocity-cubed relationship is a tough task-master.

The heart-warming tail of an Ecomodderer who put a roof-top tent on his TDI New Beetle and was dismayed by the MPG hit, accepted some friendly persuasion, and achieved better than OEM mileage with a hitch-mounted rooftop tent.

You might achieve a similar result with a long, skinny hitch-mounted fiberglass pod.
