    they discussed why they couldn’t. They need to share the architecture with Audi and sell sedans in larger volume than the 2 seater market. Also, the EV tech isn’t good enough to make a 2 seater cayman style, or even a 2+2 competitive with 911. Batteries are very heavy. Even Tesla with the best battery tech in the world, by far, isn’t doing this and the future roadster will be < 10,000 units annual.

    this is Porsche’s 1.0. Has some rough edges, but it must be done.

    Interesting little cartoon graphics on that sticker.....any idea what the 'snowflake M+S ' might be telling us?
    The Turbos will be delivering to North America when the ice and snow is still flying around and that rubber is "Summer" by Porsche's definition in their Taycan brochure.

    I see Pirelli has Winter Sotos in those sizes but I've never run that wide a rear winter fitment on a Pcar.
    Plenty of time to prepare however the discussion will come up.
    On delivery the owners manual will no-doubt have a 'Winter' tire size noted but I'd want to have ducks-in-a-row long before that.

    For winter wheels and snow chains I found that there is in the Germany configurator some available options.

    Very interesting.
    Both rim and tire sizes........incredibly helpful.
    Pairing back to 20's and 285s in the rear......still wide, but very helpful.

    I'd be curious to do some math on the OE Turbo 22" tires (front-back rolling diameter).....to see if it jives w/these 20" winters.
    That would tell us, supposedly, what the drive line likes to see for front-rear rotational differential.
    For past Pcars that are all-wheel that's been keenly important to PSM.....and with the EV I would think also.
