Just to add to other folks' optimism about this.....
I recently rented a 2018 Leaf SV on Turo for 24 hours. I rented it in northern Virginia and put almost 200 miles on it driving through Virginia, Maryland, and a corner of West Virginia. Temperatures were very hot -- mid to high 90's. Here are some notes I took on highway range and charging speeds. My original plan was to test highway range and charging speeds on Route 95, since I often take this interstate between DC and NYC, but the only day the Leaf rental worked out for my schedule was July 3. This being the day before July 4th, and the D.C. area having arguably the worst traffic in the entire US (worse than LA, in my opinion), I decided to change my route up - I drove away from DC/I-95 and made my highway test as rural as possible so as to avoid July 4th traffic. So this was all still done on US interstates, just not I-95. Instead I took I-70, I-270, and I-81.
Also, I apologize that I don't have more exact data. I don't have Leaf Spy, and this was only my second time using DCQC stations, so I had a hard time determining the kW speeds.
Fairfax County, VA
Start SOC: 100%
End SOC: 88%
Picked up car from Turo owner with 100% SOC, 163 miles of range with AC on. Drove 23.7 miles back to the house where I was staying. This was suburban driving: county parkways and one lane roads with speeds of 35-55 MPH punctuated by a lot of stop lights.
By the time the SOC dropped to 90%, I had gone 20.4 miles. I only drove economically during the second half of these 20.4 miles. During the first half, I was still learning the car, and I definitely mashed the accelerator at least 4 times to test out 0-30 and 30-60 acceleration.
In total I drove 23.7 miles on 12% of SOC (arrived with 88% SOC, 151 miles range).
23.7/.12 = 197.5
20.4/.10 = 204
So it seems that my slightly careless city/suburban range would be about 200 miles.
Trickle charged overnight to 99% SOC.
Fairfax County, VA to Hagerstown, MD
Beginning SoC: 99%
End SoC: 58%
74.1 miles on 41% of battery
Speeds mostly at 50-55 mph, some at 60-65 mph. First half of trip was 50-55, with some 45 mph cruising. Maximum efficiency, no stops/braking. Second half of trip had a few short 5-10 mile stretches of 65 and 70 mph zones (I went between 60 and 65 in these zones), plus a big 5ish mile hill climb at 60 mph followed by a descent into Hagerstown.
Range during first half of trip: 200 miles, because the first 20 miles were done on 10% of the battery, and the next 20 miles were done on 10% of the battery, etc. This continued until about 40 miles into the trip. So 50ish mph cruising seems to have a range of about 200 miles and a mi/kWh of 200/38 kWh = 5.26
The first trip overall:
74.1 miles/.41 SOC = 180.73 miles of range at 50-60 mph highway driving. So 50-60 mph cruising would mean: 180.73 miles of range, and 180.73/38kWh = 4.76 mi/kWh
First DC charge:
Started at 58% SOC
Reached 83% in 18 minutes
Reached 84% in 19 minutes
Reached 85% in 20 minutes
Stopped charging at 85% SOC
I messed up a little here, because what I think I should have done was wait the 25 minutes or so and charge to 90%. If I had, I would have started my second DCQC at 40% instead of 35% (see below), and the second charge could have gone up to 75% in 30 minutes or less.
By the way, this charging session was a nightmare. Took me 15 minutes of driving in circles around a mall to find the EVGo QC station. Then 20 more minutes on the phone with EVGo, giving them my credit card number 5 separate times, the charging station starting and stopping five separate times, all of this being done in 98 degree heat in the middle of a parking lot with no shade. I'm assuming (hoping) that when you actually have an EVGo/EZ Charge account, these DCQC stops are more seamless - provided that the station is free, it should take 30 seconds max from when you step out of the car to when the charge begins....
Hagerstown, MD to Fairfax County, VA (via a small corner of West Virginia)
Distance: 76.7 miles
Beginning SoC: 85%
End SoC: 35%
76.7 miles on 50% of charge, 76.7/.5 = 153.4 mile range
First 2/3 of this trip was done mostly at 65 mph, slowing to 60 while going up hills. Average speed was probably 62-63 mph. During the second 1/3 of this trip I had no choice but to get off the interstate and take slightly slower roads: first, a shallow climb up a one lane mountain road at speeds of 40-50 mph, followed by a descent down to county parkways which had 55 mph speed limits and stop lights every few miles. I tried to go 60-65 mph as much as I could, even in 50-55 mph zones, in order to approximate as best as possible interstate driving. Thus, I was probably going 60-65 mph for 75% of this trip. During the first purely, uninterrupted 65 mph stretches, I was consistently averaging 150 miles of range, driving 15 miles on each 10% of battery
Range at 65 mph = 153.4
Efficiency = 153.4/38 = 4.04 mi/kWh
Second DC charge:
Started at 35 SOC%:
10 minutes: 47%
20 minutes: didn’t see, was in a mall
30 minutes: 69%
31 minutes: 70%
33 minutes: 73%
35 minutes: 74%
So if I had charged up to 90% during the first DCQC in 25 minutes, I could have charged to 75% the second time in 30 minutes, for a total of 55 minutes of charging.
1. Even in 98 degree weather, a 250 mile highway trip can be done with 2 DCQC stops and less than 55 minutes of charging time (maybe even 50 minutes)
2. Range at 50-60 mph highway: 180 miles
3. Range at 60-65 mph highway: 150 miles
4. Average overall highway range: 165 miles
5. The ideal way to do a 250 mile trip in a 2018 Leaf would be to drive about 135 miles, DCQC once for 30-40 minutes, then drive the remaining 115 miles. This of course would require having access to a DCQC station 135 miles from where you start, which isn't often the case - sometimes your two options are either 100 miles or 145 miles, as is the case on my NYC to Boston drives.
6. In my opinion, the 2018 Leaf has substantially better ride and handling than the 2017. I could also be imagining this, but the driver's seating position feels a little lower - less mini-van/CUV-ish in the 2018 than it does in the 2017. It's not quite a sedan driver's position, but it does feel halfway between a sedan and CUV.
