Max range challenge! What's your Mach-E's max range on a single charge?

2022 MME CA RT1 RWD, achieved 404.9 miles on single charge. Moderate Spring weather in Boston area, i.e. no HVAC usage. Roughly 90% local, 10% highway.

Note the 5.2mi/kwh looks suspiciously high, as 91 kWh (usable battery capacity) times 5.2 = 473 miles, and I'm not even close to it.



Car scanner app shows 4.97% remaining, even though car displays 0%. There's a buffer down there. 3.84 kWh remaining, so can probably eek out another 15-20 miles if really tried.

so..... this challenge is a REALLY BAD idea, and I would discourage participation if you care about the longevity of your battery at all. Taking the pack below 5% increases risk of killing any weak cells that happen to have slightly less capacity, and increases current as voltage drops which is hard on everything.

I applaud the effort to record high miles/kWhr average in trips.... but suggest that taking your HV battery below 5% is something you want to avoid whenever possible.

What app are you using and how are you connecting it?

Should we alter the challenge to see how many kms you can go from 100% to 6%?

So the ICE Mustangs do smoking engines and tire burnouts. EV Mustangs do battery burnouts! ;-)

I would suggest shooting for the highest average shown in trip counter over 1000 miles, or 5000 miles to show how consistent you can be. But, its just not smart to drain HV battery on purpose. Lithium is safest and happiest between 20%-80%

Veepeak OBDCheck OBD, plus Car Scanner app connected via Bluetooth

But can you beat this:


Mustang Mach-E Owns Three World Records
The first record consists of making an 840-mile trip from John O'Groats, Scotland, to Cornwall, England, while using 6.5 miles per kilowatt-hour (verified by the Guinness Book of World Records).

This is also a good idea and something easy as we could just set a new trip to track efficiency over the entire 1000 miles (1,600kms)

Note the Car Scanner app showed "HVB Min Module" voltage as 3.42V, which is still safe voltage for lithium ion battery. Also, interestingly, I didn't get into any red-colored warnings, nor turtle mode.

I doubt I can get close to 6.5 mi/kwh in real world urban environment conditions. But do note 840 miles involves charging, as you'd need a 130 kwh battery pack to go 840 miles without a charging stop, at 6.5 mi/kwh. MachE's max is 91 kwh usable battery pack.

Don't know nuttin about your high falutin equipment, just fill it with juice and go!

Likely why the screen is showing 0% charge even though the MME has some charge in reserve -- to prevent people from dropping it below a certain point except in emergencies.

Wow, that's really impressive! You must live in a warm climate haha

Interesting, I was told by the dealer to drain it as much as possible. I generally try to not go below 20% I wonder if it is even necessary to do this at all...
