Can someone put a tldr?

TL;DR keep your F82 if you got it and the G82 is still ugly. Hahaha no but the first parts kinda true.

That's a ton of work, very interesting read, thank you.

I would be more interested in suspension and tires because the first thing I noticed on the G82 was the amazing way it cornered, took bumps, and smoothed out road imperfections. The suspension is both supple and corners flat. It's by far the most improved thing on the G series.

appreciate the work. well done !

Damn! People get all excited when there are comparison videos of un comparable cars, like a two door manual whatever vs an all wheel drive tuned suv vs a stock Prius. And finally someone makes a video with the same car, different model years and you're annoyed?

You're cool with comparing an oak tree with an airplane but when it comes to Boeing 737-200 vs a 737-300, that's where we draw the line?

Ouch! Tuff crowd.

Different test conditions can lead to rather big discrepancies in the results, this why it is flawed to draw definitive conclusions on a single sample. The correct way to compare empirical results is to average several test samples of each car and compare the averaged results of each car between them.

Further, you are underestmating the weight benefit of the CCB on the G82. It is more in the ~21kg range than the 13kg you quote.

Car and Driver is a good reference too, as they usually test on the same track with multiple runs in both directions to cancel out wind. At least, this used to be the case.

Hey man, I think you're in the wrong section of the forum. There is an F87 and F80 section that seems more aligned with your comments.

Front page of the app doesn't show subforum, based on your reaction I'm guessing it's G8X

Sorry about your purchase

This is the fastest, most capable, most comfortable M3 ever made.

Understatement. Seconded

Great writeup, OP!

Reminds me of engineering school, love seeing real numbers used to quantify differences other than the standard butt dyno "feels better/worse" approach. I agree with others that it may have helped your analysis to take a larger sample size of times for each vehicle and average them out before proceeding, but otherwise great job!

Ultimately what made me place my order for a '22 comp xdrive over the '21 6MT that I test drove was the clutch feel. I don't have an F82 but my aftermarket clutch + cdv delete in my 435 felt night and day better to me than the G82 that I tested. I was really sad after testing it after being dead set on walking out that day with it. The clutch feel really changed my mind to order my very first automatic vehicle.

It sure would be cool to see if they release a future version with a beefed up clutch and extra power as a final 6MT hurrah. If so then I'd definitely revisit trying to get behind the wheel of one

The original post was a fascinating read. I recalled that randy probst (far better driver than I will ever be) claimed to go faster around a track in the manual than the automatic. G8x I'm talking.

Not to stir the pot, but check this out:

If link doesn't work, google randy probst g80 Bmw and it comes up. I recalled correctly.

Given the detailed data above and a working assumption that all else equal (grip, features, etc), how does one explain randy beating the automatic with the manual?

I confess I traded my 15 m4 manual for a 21 m3 competition basically because of the torque difference and the practical reality that, on a track, really all you do is shift from 3rd to 4th and back. 5th you are going wicked fast and 2nd is a serious turn. I will work more on my braking and "line" and worry less about downshifting now. After I break the new car in, of course.

So, I'm a bit curious the science of what is afoot with this video.

Only thing I can figure is randy is in "d3" where he should be in "s3" and if he did that, the competition should beat the manual?

More data equals more confusion!

In my experience more tq on track isn't always a good thing. I know coming out of corners in my f80 I couldn't stab the throttle and power out like you can in say a gt4 for example. It simply wouldn't put the power down. I wonder if the reduction in tq is allowing him to get on throttle sooner after turning and that is netting better times. I got a manual g82 and there are definitely days I miss gobs of tq from my f80 and it makes me wish I had the comp. I guess I will have to tune to get the best of both worlds.

Like the OP, the difference is small enough to be easily chalked up to error. Whether that error be induced by temperature on track, driver inputs, tires, etc. We know weight will matter and that there's more power in the comp. But that's about it.

In the end it is not surprising to me that the end of the last gen is quicker. We will wait until the tune evolves, which it will. In the mean time new buyers should really just buy based on what appeals to them more and not what spreadsheets say.

I believe it might be related to the fact that he left the automatic in D mode instead of shifting for himself. You can hear him yell on a few occasions when the 8AT failed to downshift early enough.

[wbM3]

Similar to the GT4, sounds like the manual would benefit from a shorter diff. .

^^ this. Can't believe Pobst did that instead of shifting manually. This video doesn't prove much one way or the other.
