1,939 mile roundtrip, some interesting data

[RickMachE]

Unexpected trip for a funeral for a relative. Drove from cold Michigan to warm South Carolina. When we departed on Wednesday, it was 30 degrees.

Battery was preconditioned with a departure time, was 55.4F when we left, with 84.8kWh of energy at 100%.

Biggest surprise of trip, 3 or 4 people asking about the car. "Is that electric?" "I didn't know there was an electric Mustang".

Trip down summary - slow speeds due to traffic, construction and local roads. Cold to start. Drove some local miles, maybe 30 or so, before charging to 97% at an empty SuperCharger across from hotel. Let's call that 100%. Used 362.5kWh to drive 999 miles, or 2.76miles per kWh.

Trip back summary - faster speeds, much warmer. Better efficiency. Used 312.6kWh to drive 940 miles, or 3.0 miles per kWh. Influenced a little by some hills with regen.

Rough comparison of first cold leg with 55F battery and return leg is 3.0 vs. 2.2, showing the impact of cold and running heat vs. AC.

Also, when you think "I drive 75mph", you forget about congestion, construction, local roads, and getting on/off highway to charge...

Charged for free at EVgo (63.03kWh), using up credits (going to dispute the $1.00 charge) and 76.4kWh at Drury Inns in Knoxville. Total charging of 675kWh to drive 1,939 miles, or 2.87miles per kWh. Total cost of $149.04 plus $17.03 at home = $166.07 or 8.56 cents per mile. Plus $12.99 Tesla membership.

Had a discussion with an EQ5 owner, as he sat charging, very confident in his knowledge. He left with new learning - there is a Tesla SuperCharger membership discount, and you don't want to sit there at 93% wondering why it is taking so long...

First leg was 176 miles, with an average speed of 59mph, which includes local driving. 2.2 miles per kWh due to the cold. Only stopped there to use up free EVgo credits.
Next leg of course had a very warm battery, and we averaged 68mph. Got 2.7 miles per kWh. Air temp was now 65F.
Final leg of the day we arrived with 76F air temp. Now averaged 73mph.
Second day started with a departure time on the hotel charger, battery was 68 degrees when we left, but air temp was 54F, so that helped. At 100%, battery displayed 87.05kWh, up from the 84.8 at home.
Our first leg was slow as we took side roads to stop at Bush's (pic below). No, we didn't get to meet Duke. Averaged 44mph, 3.1 miles per kWh.
Next leg was 59mph, 3.0. Final leg was 59mph, 3.1 miles per kWh. Hit a bit of the Blue Ridge Parkway, including a 6 mile or so all gravel and dirt stretch.

On the way home, temps really showed that batteries like to be warm. First leg was 59mph, 3.0. Next leg was 71mph, 2.6miles per kWh. Next leg had multiple stops, so we didn't get efficiency noted. Next leg was 67mph, 3.0, then 66mph and 3.1, then 64mph and 3.1. Stopped at Great Smoky Mountain National Park and went up to the Kuwohi peak, the tallest in the Smokies.

Despite the occasion, we were able to hit 3 breweries, which my uncle would have appreciated.

Just did my first real road after 3.5 years of roughly 3400 miles round trip across I 70. Might do a more detailed recount later, but the one aspect I didn’t truly understand was that at highway speeds one quickly reach’s close to the break even point between efficiency and charging speed. You simply really just can’t get to your destination any faster , no matter how risky you want to be with law enforcement. You are just trading time on road for time at charger.

Too bad you didn’t get to meet Duke. I bet he’d have been the highlight of the trip and you could have driven away with the secret family recipe.

I know. We were prepared to offer him a bitch to mate with as a bribe. Know anyone?

I did something similar over the past two weeks - 4000 miles round-trip, using I-70 for half of that. Yes, speed really impacts efficiency. Going above 75 mph and you almost add an additional 30-minute charge vs. 65, so you lose the benefit of speed. It's tough not to go fast in an MME (and there's an additional kW/mi hit in a GT), especially through Kansas. Wind also had a serious impact - in western Kansas, sustained wind speed was 40 mph, with gusts up to 55, all south to north, so it was a crosswind. I saw efficiency down to 1.6 kW/mi at 75 mph (temp not an issue).

Mine is an AWD big battery cr 1 with 235 wide tires all weather pirrelies. I saw 1.9 - 2.2 in western Kansas with cold weather but relatively little wind. On the way west it really was telling that all these choices were irrelevant. I was going to get back to Colorado when the temperature and wind dictated. So I set the cruise reasonably and let BC take over. … also didn’t hestitate to accelerate to stay away from trucks and idiots.

Just returned (now) from a three day 1700 mile trip from Northern Wisconsin to Springfield, Missouri. My Nephew died suddenly. Going south into a constant headwind averaged 2.2/2.3m/kWh for most of the driving around 68mph. Driving north today with somewhat of a cross tail wind 3.0m/kWh. Positive experience with multiple EVGO/GM locations and quick plug and charge. Only used a Tesla at the Bucees in Springfield, Missouri which is a place words can not fully describe.

I was wondering about that. I usually drive 8-9mph over the speed limit. ("Nine you're fine. Ten you're mine!" A quote from a local sheriff.) I'm planning a trip in June that I did 2 years ago. In my Tacoma it was 11 hours. ABRP is putting it at 14. Not looking forward to an extra 3 hours!

I used ABRP and after adjusting the setting to really be calibrated against the performance I was seeing, found the time estimate to be pretty good

Oh my 1700 miles trip was at least 6 hours longer and as much as 8 hours compared to going cannonball style with my ice vehicle.

I did something I didn’t think I would ever do. I rented a 2023 March E from Avis in Orlando to drive to see my Dad in Ocala. I don’t usually take my March E at home on trips, but since I bought it in Dec 2022, there are many more charging options. I left Avis with 88%, and while I didn’t need to charge on the way there, I did stop at a Pilot to charge back to 80% since there are few charging options close to my Dad’s house. FYI, the car did not have any adapters or mobile chargers in it. Luckily, I brought my NACS adapter to give me the most charging options.

One thing to note, while I stopped at the Pilot travel center to charge, I saw a BMW i4 and Rivist R1S pull in. The BMW and Rivian was charging at over 200 kW, while the Mach E started at 108 kW at 59%, about what I experienced with mine. If Ford wants to compete in the EV space, they have to improve their charge speeds going forward.
