EPA range and efficiency of MME

[Machemark]

This is just speculation but I think Ford is underestimating range. Much like Chevy and the Bolt's range.

Tesla per their forums seems to, in some cases, grossly overestimate their range.

I've seen some forum posts that only get 230-250 miles per tank with their Model Y when they are rated at 300+.

Granted I think this also has to do with the calculations still being new and probably not rated or calibrated correctly. Meaning there's probably a few more variables thrown in that can effect efficiency, like motor type, software tweaks, that we just don't know about yet.

But still, 88 kWh usable battery will drive you fewer miles per kWh than Tesla MY 73kWh.

Thanks for the feedback. The efficiency is probably not battery dependent, the worse efficiency being a holistic effect. The jury is still out until production vehicles start coming out, but unless Ford is also using the same methodology as Tesla, I am expecting the real world range to be as good, maybe even slightly better. I may be being optimistic here but I have a feeling Ford will give a more real world range estimate, vs taking whatever maximum EPA testing yields.

Agree, and EPA will give you some clue about this as well. Anyway, I am really waiting for the real numbers to show up.

A little but unfortunately not much. EPA numbers are just a hair above useless for 75 MPH speeds. While there seem to be conflicting reports, one thing I read said even their "highway" number only averages 55 MPH. It can be 20% worse at 75.

I've seen Model Y range estimates vary on YouTube from 225-270 miles.

If real world testing comes out to show the MME Premium AWD ER does 270 miles on the freeway then Tesla fanboys heads will explode. They'll predictably retreat to arguing about charge times and charger networks.

What’s the use in extrapolated estimates? Drive the car from 100% SOC to 3-4%. Everything else is guesswork.

On those really cold days (<0F) between the battery losses and heating the Focus Electric's range could be as low as 50% the summer range easily (even lower if you cranked the heat).

Of course 1/2 of 230 or 1/2 of 300 is still more range than the summer range of the Focus Electric (even the "big" battery version).

So I'll still be ahead LOL.

For those with just a chilly morning automatic preconditioning is your friend--you won't even have warm air blowing in your face because the car will already be up to temp.

Under very special conditions. I was never able to get close to 300 miles even when driving very gently and less than 55 mph. Some people report that did that.

I wonder when we will get an official EPA rating and what even most important miles per Kwh data?
It is so close to production but we still do not have these essential things..,

We have solid reports Ford plans some Mach E deliveries starting in November. However, that was when Job #1 was still slated for late October. With the move of Job #1 to September, we may see October deliveries. Delivered vehicles will have to have EPA ratings. While I don't know this for sure, I believe the final EPA ratings have to be from production vehicles, not pre-production like was rolling out in July. Ford engineers can, and most probably have, run EPA tests on prototypes and pre-production units to tune the vehicle to reach engineering targets.

However, it's reasonable to assume final EPA ratings tests can occur with early production units that may even precede Job #1. As they will need to do this for each model, I think this is part of why they plan to run at least limited production of all non-GT models in the first run (production before 12/31/20).

So I would guess we'll see the real EPA ratings in September at the soonest and October at the latest.

There has never been any indication there will be a heat pump in the Mach E.

Asside from the baseline specs, the thing that has the most affect on range is driving style. any random two drivers cabn have vastly different driving styles and will have quite different ranges.

And if there's no charger near that 3-4% mark?

That's the point - getting an idea of how many of those looong refuel stops we have to make on road trips. And whether it's even possible to do the trip at all.

It would be pretty easy, albeit boring, to force that.

The problem is you're getting a bad idea of it. There isn't enough precision in the data, unless you plug into the CANBUS. For example, if you watch you toggle back and forth between the range display and the percent display while charging, you can sometimes see as much as 5 miles of range added before the percent rolls up. Which number will you use for the extrapolation? There are 10-20 miles of uncertainty just due to rounding. And then, you've just looked a one particular case.

A trip planner which looks at actual routes, expected speeds, etc., is a far better tool.

Yep, this will be of much more importance than any published differences in EPA range.

In my Leaf SL+ with a 62 KWH battery, I can get over 280 miles accelerating sensibly in Eco Mode on Secondary roads. If I hammer it down I-90 at 85 mph or so, it will be less than half that.
