I couldn't find CdA for it but plugged Cd .355 into the aero calculator and jockeyed the frontal area around til it spit out approx 8.9 HP for aero load at 55 mph. Frontal area value seems a bit small... but anyway, the rolling resistance HP requirement should be about 3.5. I don't think the 8.9 is the total HP requirement at 55 mph; besides, the fe is too poor for that to be the case.
