A stock Arcimoto FUV weighs 1200lb and has 80HP. Koenigsegg has as new, very similar drivetrain that weighs 200lb and has 670HP www.motortrend.com/news/koenigsegg-gemera-quark-terrier-motor-specs-details/
I'm interested in a four-wheel class so add 200lb, 100 for drivetrain and 100 for a tandem bogey rear.
Assume a sub 0.20 Cd (Arcimoto front A-arm suspension), and 1400/670 power to weight ratio. For purposes of argumentation, what would the Cd be? |
Sighard Hoerner would have us figure the CdA of each component, and add them together, along with a hook-vortice, 5% interference drag added to that total; then divide by the total frontal area. That's how Messerschmitt Aircraft Company used to do it. Hoerner worked for them.
Since the rear tandem wheels are almost completely wake-riding, they might be considered a freebie.
