I just did two 240 miles trips (a round trip journey) in my 2022 GT and was right around 3.0 mi/kWh. Using accessories and climate control, driving pretty quick.

306.4 miles actually driven, 311 full range, on a single charge, 21 Premium ER AWD. GOM shows 340 next run. We shall see.

Have a question for you all on this topic. I'm wondering what the most reasonable and optimal highway speed might be to get the most range - highway meaning no frequent stops/starts from traffic signals/signs. So a speed that you can set the cruise at and get the most range without turning a 300 mile trip into a 12 hour affair.
Just like with an ICE vehicle, slower gets better mpg/mpkW. There are two problems with this. First, going so slow that it's dangerous. We had to slow down to make a charger a few weeks back, doing 55 in a 70 zone on 2 line in each direction highway. Everyone passed us. We put on our hazards.

Second, it's boring, and embarrassing, to drive 15 miles per hour below the speed limit. It will take you longer to get to where you're going, and I didn't buy this vehicle to maximize miles per kWh.

One thing to point out about all these mileage claims. Some people live in areas that are flat. They will always beat everyone else's efforts. I have owned an F-150 for 8.5 years. I get 18 to 19 mpg on the highway, once saw 21 for a short period. People in Florida regularly get higher due to its flatness. But it's boring driving there...

It could be I am driving less aggressively, and it could be due to weather, or both. But my average consumption per mile is getting lower. In the month of June, which is only a week so far, my average range is 254 miles. Most of my miles are highway miles, with the cruise set to 80 mph, so that definitely has an impact.

I just took a 2 hour trip a few days ago in my GT non PE and with the cruise set at 80, was getting about 2.5 miles per kWh. With an 88 kWh battery, that gives me a range of about 220 miles. Temperature was about 60 degrees. Was hoping for better trip range than that but I'm sure things will improve.

That is probably as good as you are going to get at 80 mph. If the terrain is hilly, you will do worse. If it is raining, you will do worse. If it is 20 degrees outside, you will do worse. If it is 100 degrees you will do worse (assuming you use the air conditioning).

Drive the speed limit and your range will improve. I know, everyone will pass you and it is embarrassing, but that is how you will get more than 220.

My typical efficiency at 80 mph is 2.4 mi/kWh.

Yes I agree I can do better by reducing speed. Actually I did a shorter test on that trip too - I reset one of the trips on the computer and then did 70 and at least for 10 miles or so was getting over 3 mi/kWh. I can live with going 70 for some stretches.

It occurs to me that a few design changes could net some possibly significant efficiency gains. I'm no engineer so these might not be feasible or at least easy to implement, but how about these:
* I've heard some EV's have a transmission with a 2nd gear for highway speeds - how much efficiency could be gained by having the motor spin at lower RPM's? I know this wouldn't help the aerodynamics, but if it helped at all it might be worth it.
* In my GT and the other models that are AWD, couldn't one motor or the other (either the one driving the front or the back wheels) be turned off for better efficiency, even if only for highway cruising? Isn't this essentially why the RWD models are more efficient?

Just wondering...

I believe the MME uses permanent magnet motors which really can only be disengaged with a transmission.

From what I have read, permanent magnet motors are more efficient than inductive motors when in use but inductive motors can be electronically disengaged. Tesla has played around with mixing permanent magnet and inductive motors. I think some cars have a permanent magnet motor on the rear and inductive on the front so they can disengage the front when not needed.

A two speed transmission helps the Tycan do very well on the highway but it is also more aerodynamic than the MME. In the end, aerodynamics have the biggest impact at highway speeds and everything else just makes minor improvements.

Perhaps a really dumb question.....when I reset Trip 1 it will clear the time and miles but doesn't reset the mi/kw. What am i doing wrong? I have had my AWD EX premium for about since mid-April and have averaged 3.7 mi/KW overall. Just wanted to know what I'm getting now that the weather is warmer and what I have gotten since a charge without doing a little math. Thanks

Haven't used the Mach-E that much yet. If it's somewhat linear, my GOM says 269 miles at 79% battery. Given that, I estimate a 340 mile range with a 100% charge. Note, I still have less than 300 miles on my Mach-E.

Since we bought the SR Select off the lot 22 months ago for $43K and change (plus the big rebate) I don’t sweat the range crap as in it’s like a whose fuel tank is bigger discussion. After 45K miles that 68 KWH battery still puts out a consistent 240-243 miles of range and as I cruise commute at 53-62 mph on rural 2-lane that’s good for me and I didn’t pay a $7K-$10K premium. I do average 3.5 mi/KWh long term over that 45K miles and my power cost $.0634 per KWh. LOL. Now that early summer weather beckons I am at 4.1 miles per kWh regularly.

Have you tried driving the Mach-E at 50mph on the highway, as people pass and wonder why you aren't driving it as intended?
Yes. When stretching my range to reach a distant goal, in the mountains this Winter... absolutely I did.

"Driving as intended" for me means "driving so I achieve my objective". Sometimes, it meant driving my BMW 318i at a sustained 125 mph for several hours, until I blew its fuel pump, twice, and learned something worthwhile about the sustained performance limits of that car (limited my autobahn trips to 110 mph in that car after that double lesson haha).

On a long drive in charging-sparse areas in sub-freezing weather, it means reaching the sole charging station in the rural area without becoming an unnecessary burden on safety responders. Unlike that very nice-looking shiny pickup truck with local plates that passed me in daylight near-blizzard conditions in far northern Wisconsin this February at about 30 mph higher speed than mine (I was doing 35 - 40) and which I passed about 20 miles later off in the ditch with a cop car and an EMT in attendance. Hope the driver was O.K.

Embarrassment is an emotion. So are hate, laughter, etc... I can see their place when interacting in person with other people. On the road the interaction, if any, is with other cars, and the social compact is for everyone to continue their journeys in overall safety to its end.
