Yup. I think Porsche will end up being a lot more conservative than it superficially appears. They’ll make a bunch of options, split design costs with the rest of VW, and let the market decide what proportion of ICE / EV gets built. The big difference I see is Porsche is taking initiative, unlike say BMW whose strategy is wtf.I think you're right and you gave the answer also: the Cayman.
It's already known this will be a EV and a much better choice to be an electric sportscar.
That way you'll keep your 911 purists, your luxurious super saloon, your electric sportscar and an electric SUV.
Pretty much the same product line like now but right along the ICE cars.
In a few years you can follow what could happen: will sales of the 911 drop and/or will electric be more popular?
My guess is the 911 demographic transitions slowly. Like 10-15 years. Super car style hybrids will make a nice generational bridge. Eventually ICE 911s will be like manual transmissions. Available, but slower and a more niche product.
the EV cayman will be very interesting. The weight is going to be a massive design challenge. But it can be done. A 2008 style Tesla roadster designed by Porsche would be an amazing EV cayman.
