The car will be an impressive 55 pounds lighter than the outgoing 997. Not only will the power grow but the weight will drop despite an increase in size. The interior is basically all taken from the Panamera and new Cayenne which is fine as those interiors are beautiful. The only concern is all the Porsche interiors will blend together.
Early 991 ring times for the S are reported as 7:50 which will no doubt drop. A rumored 7:37 ring time was hit with a non-production based setup. What changes were done to it? Porsche won't say.
