Just finished my short trip. Total distance was 727 miles using a calculated 170.24 kWh based on % used Between charges. Calculated efficiency was 4.27 or ~478 miles on a full charge. Car efficiency was showing 4.3 on the legs after charging so the calculated vs car computer are in sync. At 93% of the EPA range while staying cool in the car despite up to 102F temperatures outside, going 70-75 when traffic allowed with the ACC on and using the massage seats, I was more than pleased with the results.
This is in start contrast to my ‘non-trip‘ efficiency of about 3 to 3.2 miles / kWh, or around 65% of EPA. The daily driving has A LOT of vampire drain while the car is parked and the BMS fans run after short trips.
So what is the real efficiency? I’m at a 3.4 miles/kWh for the life of the car or 74% of the EPA. It all depends on what percentage of time I am using it on trips, I guess, but I have a lot more confidence in the range than I did a few days ago.
