Mustang Mach-E - acceleration test by Björn Nyland

Hope he gets his hands on a GT at some point!

I saw Bjorn’s video last night. Very underwhelming times compared with Ford’s quoted times as well as the numbers I’ve seen reported in Car and Driver and Motor Trend. The ER rwd should be good for 6.1-6.3 to 60mph even though it’s the slowest of the MME range. Bjorn got 6.85-7.17 in the video and I didn’t see evidence of any wheelspin.

I do hear him mash the throttle quickly and then there’s a decent lag before the ER starts going. However, his best 0-30mph time of 1.90 is pretty quick (that’s what my Dragy has my ‘14 SS running on the street).
Also, when I overnight tested the FE 4X from our dealer I got 4.8-5.0 0-60s according to the Dragy (Bjorn was getting 5.8s according to his spreadsheet, which is pretty slow). Our SOC was above 80% for all runs I did. I think the 0-30s were in the 1.8 range but I deleted the runs. When we finally get our 4X I’ll post lots of Dragy acceleration data.

This has pretty much been my experience. While I love the instant torque, my 0-60 times have not been anywhere near the advertised 5.2 seconds.

Also something to think about is the advertised times are with a small 1ft roll out, I wonder how much of a difference that makes.

That’s correct, but Dragy gives you the 1ft roll out time in the data. Here’s a 4.43 0-60 run of mine (2014 SS Sedan) from months ago. The 1ft roll out is approx. .3 secs, so his best 6.85 would still be a longish 6.55.

Interesting that it gives you that 1ft data too. I've actually never heard of that until now, ive always just talked to people about 0-60 and that's it.

For the Extended Range AWD, Bjorn got about 5.5 seconds, for zero to 60 mph.
Car and Driver got the same result - 0-60 in 5.5, which is 5.2 seconds excluding the 1' rollout.

Ford claims 4.8 seconds, testing shows 5.2, at least in these two cases. Pretty quick, either way. But it does appear Ford was slightly optimistic in their estimates for both models.

CD got a 4.9 for the 4X omitting the roll out, so that would have been a 5.2 run. Industry standard is now omitting the 1ft roll out. And, as I’ve stated, I ran multiple 4.8-5.0 runs in an overnight test driven FE back in April. Those times are omitting the roll out as well.

If you watch the amps, you can see it's really holding back for a long time. If it gave full beans from the start I'm sure you'd smoke the tires, but they can probably give it some more juice with some programming tweaks.

Also I see the battery isn't fully charged in his tests, it should be reading >90% on his scan tool (full charge will read about 95%). This could have a small effect on the times since the battery voltage wouldn't be as high.

Looks like C&D has gotten different results. Here's their instrumented test from February, closer to Bjorn's results, at 5.1 + 0.3 rollout:

Yep. Prob a difference in ambient temps and SOC that account for the .2 secs difference.

But, I ran multiple 4.8-5.0s in the 80-90% SOC range. It was never over 90% for me. This was in April, temps were low 50s so it wasn’t even optimal warm weather for the HV battery pack.

Yep. Driving style matters to achieve the best times. I expect Ford used summer tires with very low pressures to get their figures.

The Wrangler 4xe has a similar issue. There is a definite procedure to follow in order to unlock the full 375 hp and get it to the 4 wheels effectively. If done correctly, that thing is a rocket sled. Not as quick as the FE buy not too far behind. If you remove the doors, the top, spare tire and seats......it is a straight heads up race.

A few things are different in Bjorn test, 0-100kmh is approx 0-62mph, the outside temperature he showed 14C, and the battery wasn't charged to 100%.
