That study... I'm no Tesla fan (this truck is blatant greenwashing combined with bourgeois escapism) but I don't believe that 0.48 Cd for a second, they definitely screwed that up. Here's another one with some good analysis pictures but they don't quote a Cd. I'd be surprised if it's over 0.30, they do everything right for aero except the wheel well crap.
