Yes they are different things. Your description is how I understand it. With 5 - 60 you can't use LC.

I believe the big difference between 0 - 60 times and 5 - 60 times are mostly due to launch control rather than turbo lag. There was a big difference in those times for the NA 991.1 too.

The reason there isn't a big gap for the Corvette is probably because it doesn't have a good LC to use for the 0 - 60.

The big differences in turbocharged car times between 0-60 and 5-60 rolling start existed before launch control was available. The launch control on Porsche's is typically worth about two tenths. The difference between 0-60 and 5-60 is often over a full second.

Weren't turbo engines before launch control much different than modern turbo engines?

Regardless, the NA 991.1 had a similar gap between 0 - 60 (4.2 sec) and 5 - 60 (5.3 sec) according to Car and Driver's test. So at least for the 911, it doesn't seem to be turbo related.

Pretty much identical to the 911.2 GTS numbers, which I suppose shouldn't be surprising. Very nice!
