A little joy ride...

[garyd9]

While my Mach-E GT is technically over a year old, I've only owned it for a bit over a month. (It was dealer stock the rest of the time.) Instead of the same old boring drive to/from work, I wanted to let the Mach-E stretch it's legs a bit today. I was curious about driving for a while with Blue Cruise (it's boring), how the Mach-E handles DCFC, how comfortable with would be sitting in the car for a few hours (very comfortable), and what kind of range I could expect with highway speeds...

I neglected to record actual battery power levels (from the OBDII port), and we all know the GOM isn't very scientific, so I'm using reported percentages for measurements.

Air temps were in the upper 80's (Fahrenheit) for the entire trip. I was driving through light rain about 10% of the time. The car's automatic climate control was set to 71 (Fahrenheit.)

I left home at 100% charge and drove from the Pittsburgh, PA area (lots of hills) to the Cleveland, OH area (flat) and then back using the identical route. I drove for a total of 266 miles, mostly at 70MPH. Included in that were some sustained 75MPH times, a few jumps to ****censored, but very fun**** for passing, and about 10 miles total of city roads. On both the way there, and the way back, I stopped at the same EA station (in Girard, OH.) At the first stop, I charged a mere 8% (8kWh). On the second, I charged 20% (19kWh). (I could have made the roundtrip without any DCFC, but was curious about charging speeds.)

The DCFC was as fast as expected. For the outbound trip, I started the charge at 78%, so didn't even bother to note the power level. Coming back, however, I started the charge at 42% and watched the EA terminal report 158 kW. It stayed around 140-150kW for the entire duration (of only 10 minutes.)

I got home with 36% battery remaining. Doing a bit of math:

36% remaining == 63% used

+ 28% used and charged at the DCFC stations
---
Total used: 91%.

Because I didn't get exact measurements of the battery level, I'll round the total used up to 93%...

93% battery provided 266 miles (about 98% highway.)

So, 100% battery would give about 286 highway miles. Not bad for a 2023 GT. (I think the window sticker is 270 miles combined)

Nice, I’m in the same boat as you. Had the performance for about a week but it’s a year old as well. I wonder if there’s any way to shut off the range number and just leave the percent? Tesla and Rivian offer this

That EA station is at Sheetz just off I-80. I assumed you took I-79 then I-80 and then the Ohio Turnpike and back?

Something is not right.

First, 36% means 64% used, not 63%.

Rough math you used 75kWh to drive 266 miles, or 3.5 miles per kilowatt hour. That is too high for driving 70mph or more on the highway. Should be 3.0 or less. What did you trip odometer read?

No.

I-76 (PA Turnpike) to I-680, north to Salt Springs Rd, hit the Sheetz/EA, and jump on I-80 West. North on I-480 to I-271

yeah, I was off 1%, (it's always hard to know what "100%" means) but I didn't feel it was significant considering that I allowed 2% pessimism on the charging.

Rough math suggests I used 82.8kWh, not 75kWh (91% of 91kWh) which I think is 3.2mi/kWh. I don't feel bad if my efficiency is better than what you expect it to be.

(If you assume 92% used instead of 91% - taking into account that 1% and still adding the extra 2% pessimism, it would be 83.7kWh used, or 3.18mi/kWh)

I didn't use either trip meter. I used the car's (overall) odometer (as well, I've done this identical trip a couple times in a previous car (a Chevy Bolt EUV) for the same purpose so I'm pretty confident in the numbers.) If I plot the same trip in Google Maps, it show the same 266 miles:

Your Trip Odometer has three modes (This Trip, Trip 1, Trip 2). This Trip resets each key cycle. Others reset when you reset them. Therefore, if you look at This Trip, it shows you your efficiency for that trip, as long as you look before powering down. For this trip, you could reset Trip 1 or Trip 2 when you start out, then go look when you get home and you have your efficiency.

Depending on how much of your usage is that 266 miles, and whether you reset the Trip Odometers (Master Reset on purchase?), your Trip 1 or Trip 2 may tell a different story.

Yes, I got the math wrong, you used 64% of 91 = 58.2 and bought 27 = 85.2.

266 / 85 = 3.13. Much more believable with local driving and downhills. BUT...

You likely don't have 91kWh when you're at 100%. An OBD II adapter and Car Scanner will show you the exact amount. It will be slightly less, temperature dependent, etc. And, using percentages throws you off.

In general, a GT / GTPE will get worse efficiency than other models, like my Premium. I haven't looked lately, and a software hiccup reset my lifetime efficiency, but it's probably at 2.8 right now with just over 20,000 miles.

Glad you're enjoying it!

For this trip, you could reset Trip 1 or Trip 2 when you start out, then go look when you get home and you have your efficiency.

And I used none of them.

First, I don't think the efficiency shown by them is accurate. Several people on this forum have measured actual miles driven and actual battery drain (as reported from OBDII PID's via Car Scanner) and found the efficiencies reported by the APIM trip meters to be low.

Second, I prefer doing it old school and just used the main odometer (that can't be reset.) That completely eliminates any question of when things were reset, etc. That involves noting the odometer when leaving and noting it again when done. 266 miles.

(Next time I do this, I'll do more precise measurements of the battery energy via Car Scanner.)

Depending on how much of your usage is that 266 miles, and whether you reset the Trip Odometers (Master Reset on purchase?), your Trip 1 or Trip 2 may tell a different story.

Again, I used none of them and it's not going to tell "a different story." It was a very simple subtraction problem. Ending odometer minus starting odometer. I'm not sure why you are so insistent that I counted my mileage wrong. It's borderline insulting.

(Oh, and I guess you just ignored the fact that google maps reports the exact same number of miles for the round trip... )

266 / 85 = 3.13. Much more believable with local driving and downhills. BUT...

I don't understand why my getting good highway efficiency is bothering you so much that you seem to be trying to find every possible way my calculations might be off, including the suggestion that I'm incapable of determining how many miles I've driven.

 

[RickMachE]

Never questioned the 266 miles. Questioned the energy used to drive it, because getting 3.2 miles per kilowatt hour on the highway at 70mph with a GT is highly unusual.

My normal (2023 GTPE) 76mph extended trip efficiency is 2.6 mi/kw. I can get 3.1 mi/kw…but I choose not to most days. I question 3.2, as it is not supported by peer data. If you are getting that after several observations, then awesome!
