I just read the article about the test ride an Automobile journalist had in the 991 with Walter Roehrl. Very good read, I suggest it!
One thing that stood out to me, when they asked Roehrl to slide the car, he tried a few times and he couldn't slide it. Then he adjusted his driving style, and got a nice smooth slide. He said he was very surprised though, he thought it would've been a lot easier to slide. August Alcheitner said the 991 is focused on performing, and not showing off. He said when you push it to the limit the 991 will show no drama, and will do exactly what you want it to. When you turn it in, the car will stay focused on the apex, and won't understeer, or step out of line into a slide. It will only slide if you really try for it.
Also, all of the optional performance equipment was mentioned. Alcheitner and Roehrl both agreed that these are all just options for owners who will regularly push their cars to the limit, and that the basic no frills 911 Carrera will satisfy the needs of most drivers, no doubt.
Another interesting thing was that Alcheitner and Roehrl both said the 991 felt much lighter to drive than the 997, and the journalist also said it felt lighter from the passenger seat. BTW, the weight difference is between 65-100 lbs depending on specification.
