How well does the 991.2 C4 GTS handle? Here is some data.
Sport Auto recently tested the 991.2 C4 GTS coupe at the 'ring and got a time of 7'23.77". This is certainly a good time, but let's do some comparisons. I am taking the data for this analysis from fastestlaps.com. This site may not be perfectly accurate, but seems like it is generally in the ballpark with its data.
First, let's look at the horsepower of the cars that are faster or almost as fast on the 'ring. I exclude small production, marginally street-legal cars like the KTM, Radical, and Donkervoort. The GTS is rated by Porsche at 450 HP, which I think is fairly accurate. According to fastestlap.com, every car that has a better 'ring time has at least 500 HP, and in most cases much more than 500 HP. In fact, the only faster cars with "just" 500 HP are GT3s. The first car on the list with less than 500 HP (other than another GT3) is a Nissan GT-R from a few years back rated at 480 HP and we all know that Nissan intentionally underrated those cars. Even so, that Nissan was slower, completing the 'ring in 7'26.7". This data alone makes the GTS look fairly impressive, but wait, there's more.
Second, let's look at power to weight ratios. Just to be clear, fastestlaps.com has the wrong weight for the GTS. The weight listed is for the C2. Porsche lists the weight of the C4 GTS as about 27 kilos heavier. Regardless, I'll use the power and weight figures listed by fastestlaps.com. The GTS has a less favorable power to weight ratio than all of the faster 'ring cars, including the borderline street-legal models. In addition, we don't see a car on the list with a less favorable power to weight ratio until we get down to the 991.1 C2S with a 'ring time of 7'34".
At least to me, this suggests that the 991.2 C4 GTS must handle extremely well to keep up with and in many cases surpass much more powerful cars that have more favorable power to weight ratios. The GTS must be making up time in the corners as it cannot keep up with these more powerful cars on the straights.
Just my thoughts (which are quite happy since I just acquired a 991.2 C4 GTS ;-).

I am certain that I have seen a few publications that specified that the Sport Auto test was with a C4 GTS. I am now having trouble finding links but I will keep looking. Meanwhile, if anyone has the actual magazine and can verify, that would be helpful.

Interesting. Here is a link to another thread with a German magazine dyno test of the GTS that indicates just 454 HP at the crank.

The "Sportauto" magazine tested the Carrera GTS (June 2017) with RWD:

I should have this specific issue somewhere around (either home or office). If you need any further infos from the test I can dig out...

Thanks for the clarification. I could not find an issues of the magazine to check directly. I guess I should change the title of the thread, but I don't know how ;-)
