There's a big difference in efficiency between the two: EPA 46 kWh/100 miles e-tron, 35 kWh Model X. I-pace is 44, Taycan 49. If Mach E hits Ford's number, it will match Model X, leaving it far behind Model Y.
Those EPA numbers are not what you should look at. You need to look at how many miles per KW can the vehicle go to usable battery. The E tron goes 2.45 miles per KW. The Model X goes 3.01.

22% difference. If we assume the Mach E has the same 22% difference, we're looking at 242 miles for LR RWD. Laughably, that won't be the real number. The Mach E is promising 373 miles WLTP, which is extremely high and much better than the Model X. You have to also remember that performance motors on the E-Tron are not the same as what is going on the Mach E. The Mach E will see more efficient motors to help with range vs power.

I am positive the Mach E will sit in between the X and Model Y for EPA numbers. I even forecast it will be on the higher end. I think we will be greatly surprised by the range numbers.

As I said before, I hope you're right.

I wonder when the EPA numbers will come out? Will Ford provide vehicles for testing before we order in the spring or maybe it'll get tested around the same time all the demos are going to dealers for test drives. Anyone know how early this normally happens in the production cycle?

Based on the 6 months it took to release the EPA numbers for the Aviator PHEV, I'm guessing Mach-E numbers should be out May/June.

Yes, but what does that have to do with how efficient it was?
Owners have reported up to 5.5 miles per kW range. Can Tesla owners post 5+ miles per kW?

No, in my car it is more like 4 miles per kw. I have an AWD model 3. I have never seen rated range and my average is about 10% less than EPA 310. I see more like 280 miles.

Yes, miles/kWh are what really matters. Problem is until the Mach-e hits the roads, we're stuck with using the published range numbers to back-calculate the miles/kWh.

EPA range is usually around 20% lower than WLTP. (22% on the i-Pace, 18% on the eTron, for example). And 20% is pretty much the difference between the "expected" 370 and 300 for the Mach-e ER RWD. In fact it's so inline with that that I wonder if all they did was extrapolate from the norms?

Like everyone else, I'll be anxiously awaiting those real-world miles/kWh readings that people start reporting in various situations. (Of course, even those will vary greatly based on driving conditions.)

Yes, we now know that the usable capacity of the ER battery is 88kWh. 270-300 miles range would be 3-3.5 m/kWh
