2021 G82 M4 Competition (RWD) Nürburgring Lap Times Guesstimate Thread
I'm curious as to what your educated Nring guesstimate times are for the G82 M4C AWD will be on the Nring and why? Thank you in advance for voting and keeping this a civil, educational and informative poll/discussion.
The stock F80 non-comp is quoted here as 7:52 and the F82 GTS is quoted at 7:28. https://fastestlaps.com/models/bmw-m4 https://fastestlaps.com/models/bmw-m4-gts Based on this and putting my finger in the air based on the power/weight, I guess the G82 will do the Nring between 7:30-7:40.

On what tires? The stock PS4S or the optional PSC2?

I'd say high 7:3X on the PSC2 and low 7:4X on the PS4S

so it seems like 7:30s is the mode with the mean perhaps high 7:30s, would love to get some more polls from everyone, thank you in advance!

genuinely curious as to the rationale / engineering aspects of why the G82 M4 comp would be slower than F82 comp?
I would have guessed the improved power to weight all else equal would be a faster car, but perhaps i'm missing something / people think the weight will make it corner much slower? deceptiv.M3 zamboni |

But regardless, the poll is specific about the RWD G8X, not the AWD one...

The M4GTS that has a better power-to-weight ratio than the RWD G8X, less weight, aero and coilovers did a 7:34. I don't see the the RWD G8X beating that.

A 7:30, 5 secs behind the 992 Carrera S? Do people really think it will be ~20secs faster than F8X when the G8X is basically an M5 without the power.
Don't make me laugh. This porker will probably do 7:40-7:50. |

As an owner of an S58 powered vehicle I am very confident that it's going to do this. It's a big step above the S55. Time will tell as every single one of us is speculating at this point.

In what terms is it a “big step above”? Technology wise, it offers nothing above the S55. Yes, makes more power, but it simply makes it through bigger turbos at the expense of increased lag and a higher boost threshold.

The compressor wheels used in the turbochargers are said to have been upgraded over the S55’s, while the entire charge-air system has been optimized for flow to mitigate pressure losses. An electronically controlled wastegate is also present, along with what BMW refers to as a water-to-air intercooler. Like the most recent versions of the N63 and S63 V8 engines, the S58’s direct-injection system now boasts fuel pressure that has been increased from 2,900 psi to over 5,000. This mirrors a change made to the corporate V8 last year, which allowed it to reach its highest rated output yet. Benefits include further improved fuel atomization within the combustion chambers, which is best experienced under heavy engine loads with full acceleration from high speeds. The core of the cylinder head is one of the most interesting components of the S58. Manufactured using an additive process that can best be thought of as incredibly advanced 3D printing, the cylinder-head core takes a shape that would be impossible to create using any other currently available mass-production method. If the skeletal structure seems at all familiar, that’s because the same process is used to manufacture the ultra-lightweight brake calipers of the M850i Night Sky. One of the main advantages of the core—and the new manufacturing process—is the ability to accommodate the routing of coolant ducts where they previously could not reach, in an effort to better regulate internal temperatures. |

https://www.caranddriver.com/reviews...mw-x3-m-drive/ https://www.caranddriver.com/reviews...e-test-review/ The majority of modern turbocharged engines perform better than their power ratings "leads you to believe", that is not a new story. It has to do with how the testing standards are defined. The S58 seems "underrated" in the exact same way the S55 seem "underrated". The fact is that the S58 in competition tune makes ~13% more power than the S55 in competition tune. Power-to-weight is what matters here because it is an apples-to-apples comparison. That being said, the G8XC will accelerate faster than a F8XC, that's not a question, the power-to-weight ratios tell us that. But power-to-weight also tells us it will unlikely out accelerate a F82 M4GTS. Which was my earlier point, a faster M4GTS with its aero downforce and coil-overs did a 7:34 in the AM&S/SA supertest, so it is unlikely a RWD G8XC will be faster than that.

Sadly not, because there's a big bumper in the way behind that grill

The S55 did not suffer from cooling problems, quite the opposite actually. The S58 likely needs the extra cooling due the added power it makes. But the advantage remains the extra power, not the extra cooling. It will be interesting to see how the 8AT cooling holds up with sustained track use.
