    Educated guess: I suspect the PZeros will be a big advantage in at the limit grip and feedback mainly because they are summer tires...

    Overall limit handling. I think they will struggle to get as much camber gain as one would typically put into a performance suspension...

    Nice find. So yes, they are using almost exactly the limits I'd imagined, at least in the rear. And they are getting the associated tire...

    Short answer is I don't know. Can you link the two tires you're looking at? I did mount PZero Electrics on my Model 3 before I got rid...

    Big thanks to hmp and petevb, you guys are really generous to share your knowledge with the forum.

    One can certainly still have camber gain and the associated issues, but it can’t practically get enough for the largest wheel size to...

    Circling back I realize you’re correct: the Gravity essentially must be tuned to work best from a performance perspective on the largest...

    Unfortunately good rain performance and low rolling resistance are diametrically opposed. To get good rain performance you want large...

    Lucid publishes a vehicle height of 1656mm. Do we know what ride height that corresponds to? Our Audi E-Tron GT had height adjustable...

    So this gets a bit tricky. First, coefficient of drag is a derived number. You stick a car in the wind tunnel, measure total drag (which...

    Ah… Face palm. The Lucid Gravity is listed as 65.2” tall, used to estimate frontal area. But I highly doubt that’s in the lowest...

    Ok, I decided to take a crack at this and put some guesses on paper for posterity… First, based on EPA numbers the gravity appears to...

    Not yet mentioned is drivetrain efficiency. Rolling resistance is linear. Drag increases by speed squared (basically). Power to overcome...

    The difference between the ideal being 20-80 or 20-55 may be down to chemistry. Teslas, for example, ramp fast charge down rapidly from...
