I have tracked a lot in a 911, a Boxster Spyder and I just did my first autocross in the 911, having previously done them in the Macan.
Sorry, but same driver, same skills and the Macan cannot and will not keep up with a sports car. Period. The 1000 lb plus penalty is too much to overcome. The Macan has a lot of tire, and it does an admirable job. I'm not dissing it. I own one after all. But none of my track times in the Macan S come close to mine in my 991.1 C4S and even in autocross, the Macan is about 5 s back on a 43 s course.
On the ring, best semi-reported time for the Macan is 8:15 (

Various versions of the 991 do it 30-65 seconds faster. That is an
eternity. However, a good Macan driver (of which we seem to have a few here) could easily take a bad driver in a 911, because skill is important.
But let's remove skill for a second. As in passing on a straight, just to show how ridiculous this premise is.
Let's say you come out of a corner onto a straight in your Macan GTS at 80 km/h and floor it. You'd be doing 160 km/h
14.8 s later. Do the same thing in a 991.1 C4S and it takes
7 s to get to 160km/h.
9 s in a 981 Cayman S. This requires no talent. You come onto the straight, and you floor it. Explain to me how a Macan can pass a middle of the road 911 on a track. Please. It is physically impossible unless the other driver hasn't floored their accelerator. I've never been able to pull that off against well driven cars and the numbers are irrefutable proof that it goes beyond driver talent. No talent involved in this maneuver.
In a corner, the best I've seen my lowered Macan S on stock 20" summer Michelins pull is 0.93 g. Same corner in my 911 C4S on 20" stock Pzeros I see 1.24 g. A lot of drivers don't have the skill to use the full cornering capability of a 911, so I could see how a massively overtired SUV like the Macan with a good driver could be competitive in the corners with amateurs running sports cars, but unable to hold them in the corner at the limit. But the same driver pushing both cars to their limit? No way.
I've been to quite a few Porsche track days. I'd say most drivers don't have extensive skills, and most instructors are only somewhat more talented. I'm a former F3000 racer (OK, technically I ran in non-championship races for car development in the summer of 1985), so I may be biased, but that's just the reality of it.
Racing is really just a matter of seconds per lap, and talent can overcome a lot. No question. But all else being equal, no Macan is going to take a Porsche sports car. It doesn't mean you can't have a lot of fun and pass a lot of sports cars as we've seen. But in apples-vs-apples, you won't win in the Macan.
You will leave with a huge smile on your face.
