That's simple. The laws of physics
A really perfect launch with that much power and torque needs the true weight distribution. In case of McLaren the mid mounted engine helps to transfer more weight to rear wheels at launce with ~42/58 weight distribution (front/rear). Porsche 991TTS is at the same boat but even more backward weight distribution (39/61) because of rear mounted engine + AWD. GTR has front weight distribution (55/45), but that amazing AWD helps the perfect launch. In case of M5/M6 the weight distribution is 52/48 and there is no AWD engaged to correct the traction. Meanwhile non of those cars transfers that much torque to rear wheel, because they don't need to do (since they are light). M5/M6 are heavy and need more torque to take off quickly and that's why S63TU generates over 550 lb-ft torque and then DCT provides 4.81 gear ratio (at first gear) along with 3.15 axle ratio to transfer over 8000 lb-ft torque to rear wheels at launch... Audi RS7 is very similar to M5/M6 (as far as weight and torque) and still front weight but is AWD so can launch much better than M5/M6 but not as good as GTR or 991TTS or Mac because of heavy weight...
