Purchased car in December. 90D, 20" wheels. Now have 4K miles, and the trip meter shows a 436Wh/Mi average over the last 4K miles. Car has taken an 800 mile road trip, a few 200 mile trips into the mountains, and then the rest is normal mixed city/highway stuff. It was a cold winter in Seattle, and I do usually have kids in the back with the heat on there too. Yesterday it was warmer out and just cruising on the highway for 30 miles at 70 MPH I noticed a 410Wh/Mi average over those 30 miles. This seems high!? I see in the Wh tracker that mid-high 300's is more normal. Any ideas?
