Seems the EPA range came in higher on each but they lowered them?
I thought that might be the case. It just didn't make sense to me that Ford hit their original estimates so precisely.

Are these numbers reversed? The battery is bigger, but less range?

Hmm. I can only think of two reasons for this so far:

- lowers warranty risk (if 70% battery capacity threshold is measured by range; Ford's warranty is entirely opaque on how this is measured)

- more buffer for future OTA updates that "unlock" more range
Or they want to set lower expectations for when people drive 70mph and the range comes in lower than EPA.

No, they are correct but misleading as the Mach E's USABLE battery is 88kwh compared to Y's usable 75kwh. But yes the Y has more range with a smaller battery, owing to several factors. One is that the Y has less drag (the Mach E opted for looks over aerodynamics), but Tesla has also had years to tweak their tuning for maximal efficiency. The Mach E will get better over time like the Teslas have, but for now it's a sizable gap in overall range. That range differential really only comes into play for long trips so it isn't as big a deal as you'd imagine.

Mathematically what can they increase to and leave a safe buffer?
The ER battery is reserving about 11 kWh. For comparison, I think Tesla reserve is about 3 to 4 kWh, the upcoming Nissan Ariya supposedly reserves 2 to 3 kWh.

That's a bummer, thanks.

Also, Tesla chooses to use a different set of criteria (5-cycle test, I believe), rather than the more common 2-cycle test Ford and most other use. So it's a bit of apples-to-oranges.
