2022 Mach-E Range Increase (hardware)

[BalsaDust]

Remember, no matter how much weight is taken out by Ford its still going to accelerate at the same speed due to software limitations in the traction control. Now in the GTPE with selectable traction control that could be different

I dunno, I don’t think any of the non-GTs are being software limited in their acceleration from traction control. I’ve never seen traction control intervene when flooring it, I think the threshold for that is usually much more violent acceleration than the numbers the non-GTs are able to put out.

The whole article seems like rehash and extrapolation/speculation based on Chief Engineer Donna Dickson's recent visit with Mr. Munro and his YouTube channel. Nothing new here at all.

Still, interesting read I guess.

I hadn’t seen the video, as Munro (to me) is full of himself, so he’s not a subjective source IMHO.

I disagree. That only applies to launch situations where power is artificially limited via software. From a roll, physics is king, less weight will equal quicker acceleration. And trap speeds will also reflect reduced weight.

While I do not have my AWDx MME yet, I have driven several different iterations of MME's over the past three months and ALL of them exhibit traction control when flooring it from a stand still as well as from partial throttle (software limitations versus actual "traction Control"). The fact that it can not break the tires loose is a good indicator to me (weight of vehicle aside).
Without traction control, and possibly some form of launch control, the tires would not last very long not to mention driveline parts.
The closest I could ever get to any form of wheelspin was a slight chirp and stepping out on hard acceleration during a U-turn, just before the traction control calmed it back down.
Now mind you I am no automotive engineer, but I do have over 30 years experience driving in SCCA GT3 and GT-Lite as well as the occasional Solo 1 events.

An electric vehicle relies on its software to limit horsepower and torque for many reasons not just traction control. A typical "ICE" vehicle has similar electronics to limit rpm, wheel spin and even drive shaft speed in AWD vehicles.
To see the real limitations try to get a ride in a new C8 Vette or even the Caddy CT5-V and have them demonstrate the "electronic" controls on versus off for you.

So you are saying that even with traction control turned off you can't spin the tires? That seems odd.

Remember, the Ext AWD versions probably aren’t going to spin the tires much anyway because even 346/428 hp/tq isn’t likely to overwhelm 4 contact patches on a 4800+ lb vehicle. I used my Dragy module to get times in the FE unit I tested overnight and it did consistent 4.8-5.0 0-60 runs with it being slightly damp out. I didn’t sense electronic nannies intervening, rather, it was good old AWD hook up from a dig. The RWD versions are no doubt being assisted at launch via software as the 317 lb ft of torque hit instantly.

Weight will have much more of an impact for city type driving than highway driving. If you are driving perfectly steady-state, weight will have nearly zero effect on highway mileage. Aero will be a lot more responsible for mileage on highway drives. This is why our friends who have gone with lighter aftermarket wheels are seeing declines in their highway range.

A 5% increase in range is meaningless. Now, expanding the DCFC cliff from 80% to 85% - THAT would be a welcome improvement!

There is no way to fully disable traction control. Even with it 'off' its just reduced.

far from it.

It's hard to say exactly what's going on in that video. The extreme angles may be causing the stability control to activate. There is no way to disable stability control.

That guy did another video testing the traction control using rollers under different wheels.

I'd take the cliff being moved from 80 to 85% for sure. Or keep the 80% cliff but allow 25kw instead of the highest I've ever seen, which is 11kw.

Great to hear Ford will be improving the Mach-E each year. That is the only way they would keep up. The problem is we need to jump in at a point knowing there will be improvements to follow, especially here in the early days of modern electric cars.
