MKSGR:
This 650s Coupe was about 26-27s as well (assuming a quite precise speedometer):

Markus, my R8 V10 Plus does 0-300 kph in around 28-29 seconds and from 200 to 300 something, the 991.2 Turbo S falls back almost a car length, so I think the Turbo S is rather somewhere around 30 seconds or so from 0-300 kph. We haven't done any GPS measurements yet, no time but in the upper speed range over 250 kph, the R8 always moves away very slowly. Up to 250 kph or so, the difference is basically nonexistent , unless one of the cars is in the wind shadow of the other. Your cab could be in a very good shape but the car I drove "against" is actually a factory car, so...
The McLaren 675LT is unbeatable in the 240 to 3xx kph speed range, you need a hypercar to stand a chance.
The 650S is also very fast but like I said, the achilles heel of the 650S (and most other McLaren models, with the exception of the P1 and 675LT maybe) is the 0-160 kph performance.
The achilles heel of the 991.2 Turbo S is the emotional part with the exhaust/engine sound and the outdated interior. Also Porsche changed the steering a little bit on the 991.2 version and made it worse, for whatever reasons.
The achilles heel of the R8 V10 Plus is the sometimes jerky shifting behavior in auto S mode (Huracan sends it's regards) and the high fuel consumption (in average around 2 liters / 100 km more than Turbo S).
None of the above cars is perfect but if I had to choose a do-it-all car, I would probably choose the 675LT Spider right now. Unfortunately, this car is completely out of my price range.
