After seeing a similar trip reported here from another Seattleite, I figured I'd give you info about a longish day trip I took recently. My car is a 2019 I-Pace HSE with 20" tires. There were two of us in the car.
This was on August 1st. I calculated these numbers by going to the incontrol website and pulling the data for each leg. It shows the average efficiency and the number of miles, so I calculated kwh used by taking # miles/100 * average efficiency (which is shown in kwh/100mi). I took that result to be the kwh used for the leg. I did have regenerative braking on for some of the trip, but I assume that's already built into the efficiency measurement. I'll include it as a detail for each leg also.
On August 1st, the high temperature in Roslyn was 72 degrees fahrenheit. The high was 77 degrees at our house with a low of 61. I drove in comfort mode with AC on and temperatures set to 68 in the car. I did use adaptive cruise control on the highway, which was the majority of the drive. I generally had it set within 5 mph of the speed limit.
I started with the car 100% charged.
Starting in a suburb of Seattle, we ran a quick errand of 6.5 miles from our house. According to the car's gathered data, our average speed was 30 mph and we used about 2.158 kwh of electricty for it. .6 kwh of regeneration.
From there we started the big trip to Roslyn, Washington, about 70 or so miles from our house. We live close to sea level and Roslyn is at about 2200 feet (with a mountain pass at about 2300 feet on the way), so this was mostly uphill. We drove the 76.7 miles of this leg averaging 63 mph (mostly highway) and used about 32.52 kwh of electricity. At this point the SoC showed more than 50% remaining so I felt like we were in good shape for the downhill return trip. 1.2 kwh of regeneration on this leg.
We ate lunch and drove around a bit, then turned for home. We never turned off the car after leaving lunch, so this was all in one leg -- 82.5 miles. This leg was largely downhill, but our average speed on this leg was 51 mph (probably reduced a bit by our driving around town, plus we took back roads for the last 5 miles of the trip home). This used 27.06 kwh. 3.9 kwh of regeneration for this leg.
So the total trip was about 165.7 miles, and used about 61.74 kwh. The SoC when I arrived home was about 26% (and 58 miles range remaining). That gives me a calculated efficiency of 37.26 kwh/100mi for the whole trip. That would give a total range of 224 miles if we extended the number of miles driven at this efficiency. Also, it looks like the SoC is displaying based on an 84-85 kwh total capacity rather than 90 kwh.
Data for each leg is below:
