EPA Certifies Mach-E Range Targets, 300 Miles for Premium Extended Range RWD

I hope this is sarcasm: The manufacturers run the EPA tests; they don't send the cars to an EPA lab they run the tests.

EPA tests about 20% of the cars to double check what the manufacturers say, as I understand it

Haha - Yeah someone's getting fired! But seriously, it's amazing how these manufactures can mimic the EPA test internally down to the exact MPG/MPGe. As if they've built their own identical EPA test machine.

Yes what happen to Boing?

Right and it's not like the calculations and tests are secret.

For the unsophisticated, anybody know what the EPA is for the FE?

Those 2 paragraphs are inconsistent: you don't want a 270 or 300 mile range ER, but you still want a 235 mile GT. I don't know what you really want, but I don't think any BEV is right for you.

GT = 250 not 235. Higher than my old Bolt by a good margin and much faster too.

EPA would need a "GigaLab" to be able to test all the manufacturers vehicles, lol.

The engineers have had the vehicle in the wind tunnel so they know the Cd. They know the mass. They know the efficiency of the drive train. They know the rolling resistance. And they know the drive cycles. They probably know a hundred things I haven't thought of. So the numbers shouldn't be a surprise.

ICE vehicles would be far more problematic, and the complexity of this estimate wouldn't be close to what was involved with developing that nifty driving simulator.

See the first post:

The FE is just a cosmetic package of the Premium, so Extended Range, eAWD, also known as E4X, is 270.

I have a very strong feeling that even at truly highway speed you'll get very close to 200 miles of range in good weather. I also have a strong suspicion that like Tesla, Ford is going to open up more range within a year.

The hint heard elsewhere notwithstanding, I still have doubts that 70+ MPH will only experience a mere 5% (or less) loss.

That would be fantastic, of course, but...

To all SR AWD future owner we are the winners here has we gain 1 mile (1.6km) ? of range without paying anything extra.

Don't spend it all in one place.

I wouldn't say not real, but is it not just a little strange that the official numbers are so close to estimates from a year ago?

Not strange at all. If the design and prototype engineers (including software types) have done their jobs, they knew a long time ago what the car was capable of. They know and understand the EPA testing and certainly have a duplicate facility at their R&D shops. I agree with some that it may be true that there is room in the numbers for range growth through actual real world experience and/or OTA updates. I do suspect that Marketing was involved in the precise range estimates and the release of EPA numbers, if that is what you mean. BTW, My 18 month old Kona Electric just got a range bump of about 6% due to a software update that was a "recall" of the battery system.

"EPA range" is also a very artificial construct, based on various lab-only data points that manufacturers already know about their vehicles. So it's much easier to hit them unless they screwed something up. You basically back-fit them from your own data.

Where they're FAR more likely to be off is real world range. Which EPA is quite bad at representing (high speed, anyway).

Unfortunately, we're stuck using EPA range for real range for lack of anything better.

F=ma. W=F X D.

Also keep in mind that the EPA DOES NOT TEST THE VARIOUS ECO MODES FOR RANGE. They test only the standard “default” configuration, including equipment. A lot of manufacturers do not turn on regen by default too.

Tesla does all the tricks to pad range numbers (Smaller wheels, Economy mode is default, regen cranked up to max, etc)

I don’t have an economy mode in my Tesla, and they now test all the wheel configurations...
