I can't seem to find any specs on the motors of the Panamera Turbo S or Cayenne Turbo S other than they are both 4.8 litre motors with a 10.5:1 compression ratio.

There is no software for the 16 Cayenne Turbo S yet, but I am wondering if the two motors are the same. If so, doesn't seem to me that it should be that difficult to develop software for the Cayenne.

 

Yes the are identical.

 

Thanks. If there are tunes out for the Panamera, would seem to me that they should also be able to get something done for the Cayenne. I know that there are differences (PDK vs auto trans, for one), but I guess there is hope.
