Per Christophorus vol 313, Cayman S will have the 3.4L engine making 296 hp. I guess this is the same engine as 99-01 996.

I think it'll sell like hot cakes. I just don't know why Porsche didn't deploy the same engines as 987. I think it'll eat into 997 sales and signal that 987 is lower performance just because it's a cab. Both 997 and 987 are so new and the intro of Cayman's performance will hurt existing model line up.

Personally, I'd like Porsche to invest in a sedan platform as I see lots of potential there.

 

I'm willing to bet that soon thereafter Porsche will put that engine in the Boxster S, or do a Boxster S Clubsport
