Mach e RWD Ext.range TP+
Country flag
The Mach e X has a range of 600km WLTP (373 miles), while according EPA it's 300 miles.
The Polestar 2 has a range of 470km WLTP (292 miles), while according EPA it's 270 miles.

So the EPA-results are quite close, while WLTP is way different. Does someone know why?

Basically, the EPA range is considered the most accurate for real-world use. There's a lot of info out there to tap into that helps explain it.

As for the Mach-e specifically, it's all just computer modeling at this point. EPA hasn't even done actual testing yet. The current number is just "targeted EPA range".

These 1,21 figures suits the Mach e ranges?, but for the Polestar it's only 1,075o_O

The key takeaway from dbsb3233 is that Ford's Mach E numbers ARE TARGETED VALUES; they have no actual meaning other than Ford's hopes/dreams/guesses until certified values are published by the relevant agencies.

You missed a "1" in there. They're saying an average of 1.121, which is actually pretty close for the Polestar. The Mach-e comes in at 373 / 300 = 1.24, while the Polestar comes in at 292 / 270 = 1.08. The Mach-e does show a much bigger difference than most. It is hard to understand why, because as far as I know, they're both just "targeted" estimates by Ford (no real testing yet by EPA or WLTP).

It leads to a lot of speculation and hope that the real-world number will come in closer to the WLTP target than the EPA target, but there's really no way to know yet. It's all just Ford's computer projections at this point. And on a brand-new vehicle design like this, it could be off 5%, 10%, even 15% pretty easily.

What if it was 330 mile EPA range and 300 mile range for AWD? That would be a great addition to an already awesome looking vehicle.

the other American / the 3 long range has a WLTP of 348 miles and real test from full to flat battery of 251 miles at around 32 degrees . So we can deduct approx 28 prct from WLTP to get the True EPA ?

Maybe. But the better approach is probably just to ignore WLTP altogether and just go by EPA, as it usually proves to be more accurate.

Although again, that's for the actual EPA rating, which we don't even have for the Mach-e yet.
