EV only stats for Ford C Max Energi and Frontal Area
Height 72 inches x width 60.5 inches = 30.25 sq ft.
Minus ground clearance area, minus tires
= 30.25 - 1.66 = 28.59 sq ft.
Cd = .30 x area 28.59 = Cd A = 8.577
I seen one report of a 27.6 sq ft frontal area for the C Max Energi which makes sense because to car gets narrower towards the roof. that would give it a Cd A of 8.28
My trip one is showing 92.5 EV miles on 19 KWH which = 4.468 miles per KWH which equals 223.8 watt hrs per mile.
19 KWH including charging loses 19/.88 = 21.59 KWH
92.5 miles/21.59 = 4.284 miles per KWH, 1,000/4.284 = 233 watt hrs per mile.
Keep in mind there is no specified speed here. I have yet to reset the trip and do a energy speed test. I would be interested in 75 mph, 65 mph, 55 mph, 45 mph, 40 mph, and 35 mph.
The test above includes lots of city driving in stop and go traffic, with regenerative braking. Some hwy driving.
