very strange short shifting behaviour by Jorg
at the last part on the long straight going uphill he short shifted to 7th and the car basically hit a wall and stopped accelerating when the momentum was lost. had he kept it in 6th i would love to see if it matches the M4C which hit 289 at the welcome home sign |

after such extensive testing there must be a reason for this? "Fahr nicht schneller als die M drei[3]" don't drive faster than the M3 csl "Ja Meister" Last edited by G30M; 06-17-2022 at 04:54 PM.. |

Power to weight will do that at any hp number while the absolute hp number is more important for terminal speed on that long straight which can mean seconds.

He has I’m sure, the 7:16 CSL time is massively faster at the surface but when you factor in that the tires are very different something doesn’t seem right with the CSL time.
It’s observed that the Cup 2 R is up to 0.5s faster per kilometer than the Cup 2. That’s 10s on Nordschleife. Porsche’s hot shoe Lars Kern agree, he had this to say about the Cup 2 R on the 992 GT3: “Of course, a lot of the new GT3's 'Ring time improvement comes down to the optional Cup 2 R tires. But Kerns says simply swapping those tires onto the old GT3 wouldn't get you anywhere near the new car's 17-second-per-lap improvement. Even on the less-aggressive Cup 2s, Kern estimates the new GT3 should be "at least" seven or eight seconds quicker than the old GT3” This would make the CSL 4s faster than the M3 Touring on the same tires. It doesn’t seem enough with the power, weight, aero and cog advantages of the CSL. It become even more strange when you compare with the M4C Sport Auto time of 7:31. A 15s gap to the CSL. If the R tires is a 10s gain and the factory vs Sport Auto driver difference is similar to the 9s it was for the M4 GTS’s ring time, well then the M4C would be faster with some margin than the CSL on the same tires… It seems that maybe the Cup 2 * tire could be much closer to the Cup 2 R than we think or BMW has sandbagged the CSL factory time. Something is off. |

I'm more on the theory that the M3/4's times are great for everyday road cars (which they are, from coupe to touring) and kill all competitors, but rather poor as true track cars (M4 CSL), which means that starting from a road car you can't achieve too much on the track, even with massive work and fine tuning it's physically impossible to turn a 3-series into a track car (mainly due to weight and weight balance). |

But does this really explain the only "marginal" difference between M4 CSL and M3 waggon? It would explain, why a M4CSL with any effort you put into would hardly reach a pure sportscar (like 992 GT3) ... but why doesn't pay all the effort put into the CSL over the touring (weight, tires, power, aero) out more? Since several informed people are asking this (see your posted video) I think this is a valid question! Will be interessted, whch time Christian Gebhardt does in the M4CSL supertest. |

I think an M4X on Cup2Rs would be faster than CSL. CSL had a lot of time part throttle when Xdrive would just put down all available power. CSL is lighter and more power but RWD can only get you so much corner exit speed.

I still think there’s a chance of some sandbagging here. |

just looked up the Autosport driver in question. turns out he is a 4 time 24hrs Nurburgring race winner ...
so this guy drives around the ring faster while he's asleep than when most people can do when they're awake https://www.driverdb.com/drivers/christian-gebhardt/ Last edited by G30M; 06-20-2022 at 02:37 AM.. |

but yes I am surprised at the abilities of Japanese FWD, how they have matured over the years no doubt thanks to racing experience |

i watched the start of the CSL vs Touring in the first 30s alone, the CSL was pulling a max 1.8G in corners while the Touring maxed at 1.5G CSL consistently between 1.4-1.6G while Touring 1.2-1.4G i think there is no comparison here. the CSL feels so easy while the Touring was getting wrestled against understeer is what those numbers are telling me.
