I took my M3P+ (20" wheels with Pilot Sport tires) on a 46 mile trip this morning to test its efficiency. It was an out and back on the freeway, going between 65 and 75 MPH. I probably averaged around 69 mph. I got
296 wh/mi.
Outside temp: 55F, inside set to 66F with AC off.
Used auto-steer for more than half the time.
Tires started the day at 41 psi all around.
Just me in the car.
My trip with 4 in the car yesterday from Portland out the Columbia River Gorge and back, with some wind and rain on the way back to contend with, and averaging around 70 MPH over 285 miles was pretty bad, at
356 wh/mi.
I sure hope my car gets more efficient, but I don't know that it will. Makes me wonder if it's a bit out of spec, compared to what others are getting. I'd love to hear specifically from more folks with non-aero wheels & pilot sport tires - what efficiency are you getting?
