Anticipated Range of Extended Range Mach-E

Someone please add clarity to this:

If the AWD extended range battery Mach-E has a range of 270 miles, is this from 100% charge to 0% charge or is it from 80% charge down to 20% remaining? If the former, is the real range 162 miles (60% x 270)?

Let's see, when the ICE motor car replaced the horse there were few petrol stations bad roads and mechanical glitches. How many on the forum ride a horse to work or on holiday? I will not be able to make my daughter's in Utah with out a charge ( I got the RWD/ER), So what, in the grand scheme of things is an extra 6 hours a year hanging out at a charging location, which will in all probability go a long way to keeping me out of trouble. I once made the drive from Long Island, NY to San Diego, CA in 2.5 days. It then took me half again that long to recuperate and at the time I was in my 20s. I truly understand the range issue, that's why I bought a RWD. However, as I have stated in other posts 99% of my driving will well be in the range of an MM E on a home charge. I bought a PHEV to make the transition to a BEV and I'm looking forward to being part of 'the future' of automotive technology. For me and only me I won't buy a vehicle with paint issues, leaks, roofs flying off, cabin noise no instrument panel or doors flooding to save a charging stop. I do however support the choice of purchasing/leasing ones vehicle of choice because I'm a loyal libertarian who believes that Adults have the right to do what they want as long as it doesn't result in an increase in my taxes to pay for it. Happy Thanksgiving🦚That's either a tree or a turkey , I don't have my glasses on

Yes, that is from charging to what the car calls 100% down to what the car calls 0%. There is a buffer at the top and bottom ends of the battery, which is why the physical battery is 99kwh but Ford reports it as 88 kwh. The car will never let you drain the battery to absolute 0 because that seriously damages a Li-ion battery, nor truly charge it to 99kwh full because doing so on a regular basis also damages the battery.

For example, when the car reads 100% it probably is holding 93kwh, and when it reads 0% it will likely still contain 5kwh. To protect the battery from damage it won't let you directly charge it or drain it beyond those limits. However, if you leave Li-ion sitting for a long time it will discharge, so you never want to leave it sitting at that low of a level for a prolonged period.

So yes, you only get 270mi range if you take it up to what it reports as 100% and drain it down to what it reports as 0%.

So I am driving a BMW 328d with a 15 gal fuel tank. We average anywhere from 42 - 48 mpg on this vehicle while on the highway, including long road trips. We have on occassion gone 700 miles on one tank full when we knew where the next diesel pump was.

The 270 expected range comes from the 88 kWh of battery Ford makes accessible to you. (Ev-database says they expect real-world range to be 268 miles).

The other 11 kWh of the 99 kWh pack (~11%) are restricted from your use by the battery management system (BMS). Ford may make some of this available in the future as they get more real-world data back.

A question i have is: Being there is 11% reserved, does this reduce the usual 20% charge floor to 10%? My biggest reason for wanting to get my hands on the user manual is to get Ford’s charging recommendations.

as for range anxiety, I’m going to throw some food for thought out there. If I had a Ford Edge with a 18.5 gallon gas tank, it would go for 425 miles if I somehow managed to match the EPA combined 23 MPG rating. I never go to empty. So assuming I leave at least a 1/4 tank before refueling, my theoretical range would be 319 miles. I also only pay cash for gas, so i usually add $20 gas at a time (10 gallons at my current gas prices). So right now my range between refueling is actually 230 miles (55% capacity). This doesn’t take into consideration environmental impacts on MPG.

In my book when it comes to refueling, the only real difference between BEV vehicles with a decent range and an ICE vehicle is the ‘refueling’ speed.

Great point. You could add the convenience of home charging (re-fueling) too.

Personally, for long trips (over 500 miles), we can use my wife’s car. Its not that frequent we do, though.

As a range example, I mapped out from Freeport, LI (picked because of distance) to Ludlow, VT, 253 miles on ABRP. If I leave with 100% charge it says no stops. I would make at least one stop somewhere on the route and grab a 30 minute charge to be safe.

This is only good if there is destination charging in Ludlow.

And this is all speculation anyway. we don’t know what the EPA and real-world test numbers are yet.

Again the 270 miles is the maximum range for the FE - LR AWD: It is calculated in both city and highway. The city driving is always higher because of brake regeneration.

At speeds (70 to 75 mph) the 270 drops to 240, without brake regeneration another 20 to 220 and with heat on in the winter to under 200 to 180.

That 180 is once again the maximum and with a 20 mile reserve your are down to 160.

Without "nit picking" Google maps shows the distance from Freeport LI to Ludlow to be 258 miles and 250 from my home. My ski house is in the center of town which accounts for the extra 4 miles.

I am not sure, but I believe the range is with the buffer.

I had read that the buffer, low and high end combined, is closer to 10/15% and not 40%.

One of the ways that Tesla keeps increasing the range of existing cars is through OTA updates that modify the buffer. I think their total buffer is now around 5 to 8%.

Others I am sure will post more accurate information.
