Five months of ownership and 1,621 miles shows 237 wh/mile. My wife just drives this car about town on errands, so maybe drives 50 miles per week. We did drive to the service center for a day trip, and then took another day trip to Gilroy and then down to the Kettleman City Supercharger. On those trips (I did most of the driving) our wh/mile was closer to 220.
We do not have the aero wheels.
And my lifetime wh/mile on our 4-year old S with nearly 50,000 miles is 278. So perhaps I am a much slower driver than most.
