I saw a M/T review/comparison of the new 991.2 CS (PDK) compared to the C7 GS (manual) and the CS walked away from Vette--0-60 and 1/4 mile. It's a rocket making you wonder why anyone would consider the Turbo S for a lot more $--meaning more than the $140K on that particular CS. When they got on the track, the GS was a second faster/lap courtesy of bigger brakes, bigger tires.
Money wise, though, there was a $40K spread between a optioned out CS and GS.
