Mach-E EPA Ratings Revealed in Window Sticker!

[efisher]

Anyone else notice the prices don’t match up? Premium starts at $47000 and AWD ER batter is $7700. When they dropped the price a month ago did they just up the price of the options?

It's the paint color upgrade that accounts for the difference.

Yes, I know, but the tesla salesman I phoned today told me that, indeed, the new battery technology installed on the German-made TMYs should no longer have this limitation.

I believe that a salesman told you this, but bear in mind that the vast majority of car salesman know next to nothing about cars. This holds especially true with Tesla from what i have seen. I wouldn't count on this at all. The new batteries going into the German Ys and 3s aren't the new battery technology announced at Battery Day in September, they are just a slight improvement over current technology. At any rate, it isn't something I'd worry about unless you have a requirement to frequently charge your cars to 100%. Charging to 100% for the occasional long drive is not going to cause any measurable battery degradation in either the Mach-E or the Model Y. On a daily basis I charge both of my Teslas to 75%, because that's even better than 80% and still more than enough for my daily needs.

This may not seem like much but losing 10% of your range is quite a big loss if you have long commutes or live in very cold places where it's not uncommon to lose 40% of your charge already on very cold days.

So don't use that setting. It's a recommendation, something you can choose to follow or ignore based on your needs. Depending on how finely tunable that control is, you could probably even find a middle ground at 95% or something you're comfortable with.

Also bear in mind that a big chunk of the battery degradation comes from the time the battery sits at 100%. Setting the schedule to have the battery finish charging just as you're ready to leave mitigates much of the damage and gets the battery warm for your drive as well.

I'm also a little skeptical that these are even real numbers, the sticker is still mostly blank and maybe only based on targets.

Are we sure about the buffer size because if the buffer size is so big why does the manual ask us to only charge to 90%? I was sort of hoping that we could always just take advantage of the full range by charging to 100%.

This may be an indication that they are reducing the buffer to improve their EPA ratings. Fact is sometimes you don't always know when something is going to come up and you need to have that extra range. I charge my volt to 100% all the time and never have had any degradations as a result that I've noticed and it's been over 3 years.

What other battery operated product do you know of where you are told to only charge to 90%? If this is required than it should be built into the buffer and the only reason to not is to get better EPA ratings or just allow drivers to purposely or accidentally accelerate their range degradation over time?

The buffer size we know for sure. If the sticker is real, who knows?

The 90% still makes sense given that battery life is maximized when you generally stop charging around 80%. If you consider the approximately 10% buffer along with the 90% suggested charge that is around 80%. (Not exact but in the ball park. So please don't start a long mathematical analysis.)

Tesla is very much a "study to the test" brand. They design their hardware and software to perform optimally under documented test conditions but as a result it performs much less well in the real world. It's not as bad as VWs "detect the test and revise operation" strategy but it is still designed to deceive the consumer.

I disagree. Tesla uses the EPA numbers which as it turns out are pretty darned accurate at 60 mph. I have a stretch of highway that I drive a lot in the summer @ 60 MPH. Pretty darned hilly too. (They'd call it mountainous in some parts of the country...) I always meet or exceed the stated range of the Y. It's not Tesla's fault that some people aren't smart enough to figure out that you're going to get less range at 80 mph in a driving rain. I drive up a mountain and back in a snowstorm, and while it's fun I get a massive hit in range, it drops down to just above 200. Or, about what I expected it should do. Is Tesla deceiving folks by not putting on their website "If you drive up a mountain your range will suffer?" Of course not. People should be able to figure some shit out for themselves.

I'm going to guess that the Mach-e is also optimized for slower speeds. This is just a guess. But if it is, It's going to suffer an even bigger penalty at 80 mph than Teslas do. Why? Because the Mach-e is a significantly less aero than a Tesla. So as aerodynamics play a bigger and bigger role as speed increases, the penalty for the muscle car looks will get proportionally bigger. Is Ford deceiving customers? No. It's just that in life there are trade offs.

The sticker has been confirmed as real by members of this forum who I believe have inside information.

Yeah the Bolt doesn't have much of a buffer at all (as borne out by the fact of the recall: Reports are that the fires are due to over charging the battery or some "component").

It does indeed turn off regen until you've used up some of the battery below 100%.

In reply to a post about regen braking:

Sorry, wrong does not affect the mache.

Are you saying that the Mach-e does not have reduced regen braking at 100% SOC? How is that possible? Where does the current generated go then? It can't go to the battery without causing significant damage. (And possibly setting the battery on fire...) The kinetic energy of the vehicle has to go somewhere, it can't be destroyed.

Why can't it go to the battery? The BMS is imposing a min and max on battery SoC during charging. Perhaps the max is a bit higher while driving.

Not saying @trutolife27 is right, simply pointing out that what he has claimed can easily be correct.

That's what the C-max does. The battery indicator will show full but you can still regen past that point. Simply because 100 that you see does not mean battery is at 100...reserve.

At some point it will stop taking a charge at all past "full".

Ford decided to enter the BEV market with a car that was not just a compliance vehicle. That quote is all over the place. Many of us signed up for the Mach E because of that, and aware of the range.

All good in my book, and I am very happy I will have a FE Mach E.

The sticker lives up to the promise, and I won’t be driving around a jellybean compliance car.

Model Y has better range with same performance/utility as Mach E...that is a competitive issue for Ford. Yes Tesla has fit and finish problems, but Ford has released their share or poorly built vehicles too (time will tell if the Mach E build quality is up to snuff). Tesla does not need to build "compliance cars" since their entire lineup is EVs.

Keep in mind if you charge to 100% , you lose re-gen braking until battery capacity is depleted to 90% or so. And if you’re worried about losing range, that’s factored into the EPA rating.

I guess there could be extreme cases, like charging 100% at the top of Pikes Peak. But I would struggle to find a normal driving condition case where the vehicle couldn't regen. You would have to have a trip where the range at the end of the trip is greater than when you started.
