It basically says there is no mechanical torque vectoring. They accomplish it with software, which basically means brake and motor output adjustments. Pretty cool stuff. I bet it works pretty darn well.

Hence no idm in front, just braking and motor. The GT then will have some monster awd capability the w 2 idms

I think that is correct.
Looks like an IDM in the rear. That motor is larger (of course) and liquid cooled via oil to water coolant heat exchanger.

The front motor on non-GT models looks like a component assembly where the motor and gear box are bolted under a sub-frame with the charger, inverter and DC-DC converter on top. Water cooled.....but without an oil-to-water heat exchanger for the front motor case. Not sure I like that....but it's a pretty small motor so heat might not be much of an issue up there.

No charger or DC-DC converter out back.....which makes perfect sense. Just the inverter so I think in the whole scheme of things the heat sources are well balanced. In fact, the charger would only be generating heat while plugged into L1 or L2 anyway so having that right above the smaller motor up front is really a non-issue since the vehicle won't be driving while plugged in.

When the car is driving the front grill is supposed to open up to cool off the battery and maybe also the motor, but I would like to see Ford use the heat from the Ford motor to warm up the car like an ICE. Especialy in our winters we get a lot of freezing rain which is the hardest to melt not like snow.

That does happen. There is a PTC device that is able to scavenge heat generated by all those components up front and put it into the cabin.

When those grill shutters open, the air flow passes over the radiator and A/C condenser to transfer heat to the atmosphere. The air flow does not cool the battery....at least not directly. It cools the condenser which contains heat from the battery via the chiller.

At least this is how it works on the FFE which should be very similar to the MME based on the photos posted in the associated thread linked in an earlier post.

What is missing from those photos are the valves. The FFE has three valves. The MME should have at least 4 but could be more or less depending on how clever the engineers are these days.

I am looking forward to getting my hands on the service tech training documents because they are usually pretty helpful at understanding how it all works.

They are also helpful to fix any issues ourselves. It's going to be interesting to one day work on this car. I am used to working on my own cars and I'm a bit nervous about this one. Not sure we'll see a FSM for this car since it will require lots of specialty tools

I have the Service Manuals for the Energi models and the Focus Electric. I presume we will be able to get the MME manual at some point as well. They aren't cheap.....but they have good info.

I dont mind doing a split buy here. We'll get the forum to figure something out if somebody cant get it for us.

Talking about chassis before im wondering if it will be easy to swap the magnaride suspension. Its a mod id like to do but depends cost.

I think he meant that the first batch of cars will have batteries from Korea and whenever Poland ships their batteries those will go in the next batch of cars. So you might have the same cars from different batches with different battery origins

We know the first 8000 are coming from South Korea. That means all the FCTP, First Editions, and the next few thousand other models (mostly Premiums). After that the cells are supposed to come from Poland but that hasn't happened yet.

yeah I read that post from @trutolife27, its what i suspected. Now hopefully they can still get a constant flow of cells from either location so that there wont be any delays.

The Mach-E will no doubt have a PTC heater, but that does not necessarily mean it can scavenge heat from other sources. All a PTC is is a resistive heater.

The Bolt's PTC cabin heater is on its own coolant loop independent of the rest of the powertrain.

The valves will tell whether Mach-E can heat scavenge as well.

I have the same for the Fusion Hybrid and Energi models. I used it receintly to find the plastic rivets that attach the front bumper to the fenders.

Then whenever the lawsuit between LG Chem and SKi is settled there will be the new plant in Georgia that can produce 300000/yr by 2023.

Those of you with fusion hybrids, are the brakes more complicated to change due to the regen? Have any of you tried had to change them or tried changing them?

The brakes are just brakes.

Regen "braking" doesn't use any part of the brakes, the name is misleading.

I haven't had to change them in any of the four hybrids I've owned - 2 Honda, 2 Ford - despite over 300K miles across all of them. Regen makes them last longer.

I know that's not answering you per se, but I guess I'm saying I'm not sure I'd worry about it. ?
