It's here.
Quick facts 2.0 in the base and 2.5 with variable turbine geometry in the S.
Base is 300hp and S is 350. Officially 100 more for each then where they stood at the start.
Base 0 to 100kmph 4.7
S 0 to 100kmph 4.2 (Wow!)
Top speeds in the 170s I think.
Manual still available.
Also the Boxster is now more expensive then the Cayman.
