    I read the coefficient of drag on the new Prius Prime is higher on the XSE (0.29) than the XSE Premium and SE (0.27). The tires on the XSE and XSE Premium are the same size. What would cause this difference?

    I think that's a typo. I'm not seeing anyone listing 0.29 for any Prius except the gen1. I am seeing 0.29 for the bZ4X and 86, so maybe someone copy/pasted something wrong?

    I've seen the 0.29 mentioned early on in some reports. If it isn't a typo, the larger wheels don't have an aero cover to them. They also lift the car about a half inch. That alone would just mean increase in frontal area, which isn't included in Cd. It might result in the air flow being less clean under the car.
