Weekend trip to from Durham, NC to Athens, GA. Start temp 44F (rain) ; mid trip temp 70F; end temp 39F (more rain). Not much elevation change. 90% on Interstate 85. Frequent use of defrost, some heat. 717 miles, 192 kWh, 268 Wh/mi. No waiting at superchargers in Charlotte, Greenville, or Athens. The car eats miles like candy. Great, great road car. Amazingly good highway efficiency compared, ahem, to some other EVs. I love this car.
