Anyone planning on picking up a G8X and tracking it?

[NYG]

Roasting aside, which one of you sick bastards is gonna have one on track this year?

Are there any lap times available from BMW testing?

[SYT_Shadow]

I may, it depends on the weight. I could care less about its looks, but if it weighs 150lb more than the F80 CS it's a tough pill to swallow

Also, I've gone through development hell on the F80CS and I don't know if I have the energy to do it again with the G8X as soon as I have the F8X working properly.

There are many unknowns with the G8X. What max wheel/tire combo does it accept? Who makes track wheels for the new offsets and center bores?

I may just keep the CS longer term or get into a GTS. For sure I'll buy a 6MT G80 for the street, it sounds like a great daily driver.

[Gomeler]

The G82 just isn't a compelling story over my F82 GTS, and I have no need for a G80 when I'm looking at either full-electric or plug-in hybrid for my daily. I do look forward to seeing what people can do with the G8x, but it just isn't for me.

It is definitely more than 150 lbs heavier than a CS. I remember reading that a manual transmission/base G80 was significantly heavier than a DCT fully equipped F80. Apples to apples, G80 is going to be more like 400 lbs heavier.

I'm willing to bet money it won't weigh anything near 400lb more than the F80 CS I have. They showed the 6MT car on scales with a full tank, the same way I weighed my car, and it's ~120lb heavier once you remove the CF seats and switch to an automatic tranny.

They also said the crank in the engine is 19.4 kg in direct conflict with the 21.2kg listed in their own technical guide. Possibly the M3/4 S58 has been revised - however, you would think they would have made that clear as it's a great selling point. So not sure what to believe from these videos they're putting out.

Thinking of RWD / Manual?

This thread might do better in the G8x section if any of us could post there 😭

Doubt it, this track section (maybe M2 as well) are leagues better than the others and the F8x is getting more and more attractive.

SYT Shadow and I should try and set the first lap times at the Glen with a G8x and a C8Z06 on this subforum so everyone knows we're the shit.

RWD for sure. Adding even more weight for AWD is the last thing on my mind. A tuned G8X with 600whp on 93 octane, stage 1, may need AWD to properly function.

It would probably by 8AT unless the engine has very little lag. It seems to have more lag than the F8X... and in the F8X 6MT vs DCT was already a big difference in pace (each gearshift means the engine releases boost, then needs to regain boost).

C8 Z06 will be a cool car for sure.

There will be good suspension and brakes for the G8X quickly, but the development cycle wore me out on the F8X. I've gone through two BBKs, two suspensions...

Yeah but it sounds like the MCS and the BW BBK is the truth.

MANUAAALLLLLLLLLLL

I love manual as much as anyone else... it's not an easy decision. Boost lag sucks, it's not like a supercharged car that has NA level throttle response with no boost buildup.

We'll see. Keep the CS, swap for a GTS, get a G80... so many options, all are good!

"Well, the F80 M3 Competition with a seven-speed DCT (dual-clutch transmission) weighs 1,635 kg (3,604 lbs). Again, not a great number but a respectable one for a car with a dual-clutch auto. How about the new G80? In Competition-spec with its eight-speed automatic and rear-wheel drive, the G80 weights 1,805 kg (3,979 lbs)"

Something has changed between the DIN weight of the F8X gen and the DIN weight of the G8X gen. According to DIN weights, the F80 DCT weighed 3604lb. Less than my F80 CS. Meanwhile, we have the DIN weight of the G80 6MT at 3923.

I prefer cars corner weighed, like I do every time I have a car:

My F80 CS weighed, full tank 3657
BMW video: G80 6MT full tank with CF seats 3701 44lb delta
Assumption G80 6MT full tank with regular seats 3723 66lb delta
Assumption G80 ZCP with CF seats 3756 99lb delta
G80 ZCP with regular seats 3778 121lb delta

I'm going with this as the delta. Everyone is free to think what they want until we have proof in the form of weighed cars.


As far as information from BMWBlog, I'll use that for toilet paper. The same use I gave to their statement years ago about the F8X weighing 3300lb (or was it 3400lb?).

To further substantiate your data points, my F82 w/ full tank was corner weighed at 3660 (DCT plus exec package)

Thanks for the data point!

We'll have to see what it is, but there's no need to be pessimistic.

I'm confused. DIN weight is published as 3923 and you are choosing to believe differently, because..? What are your assumptions based on?

I do agree with your approach on corner weighting and F80 weight. Here's mine:

Damnit you have the BEST color for the F80 CS!! Mine is white
So jealous

The DIN weight spec has changed throughout the years. It's also based on 'normal spec', whatever that's supposed to mean.

BMW has a vid where they corner weigh a G8X right on the production line and show the tank is full. That car weighed 3701lb. It had CF seats and was 6MT, but we know the weights of both of those things so when I back them out, I wind up with the chart I sent earlier.

The 3923lb weight doesn't pass the sniff test. I am sure it's incorrect or not an apples to apples comparison. How could they show a corner weighed car that is 200lb lighter than the DIN weight? That's just not possible.

Many years ago when I was a little pipsqueak, a mag published the DIN weight for the RS4 with the 4.2L NA 420hp engine. It showed it weighed the same as the E92. That did not pass the sniff test. I called the mag, they called Audi and whoopsi daisy, Audi had given them the weight without a driver as the DIN weight.

I see, I'm following now. Here's the video you are referring to I assume:

You are making some very very broad assumptions. i.e., options package on the F82 they weighed and options package on G82. A fully loaded F80 compared to a stripped out G80 could be several hundred pounds just in options, even before you get to tranny and seats.

Whenever a car maker puts out a video talking about weight with selectively picked examples, it shows me they are defensive as hell and trying to hide something.

I am not going to assume anything, but inclined to believe the 400 lbs difference in apples to apples car.

This is BEFORE we even talk about AWD versions......

Yes, that's the video.

I am ignoring the F82 they weighed. I know what mine weighs, and mine is supposed to be one of the lighter F80s as it has the CF hood etc. In fact, my car is heavier than the one they weigh.
My car has no options other than exec package. I'm sure that adds some weight, but the sunshades and heads up display are not that heavy.

The G80 they have may literally have zero options, but they come with HK audio. What options does my CS have that their G80 does not?

I hope the G80 is a 'stripper model', but as far as I'm concerned my F80 CS is also pretty close to stripper.
Tranny and seats are well documented weight-wise.

AWD optioned cars should weigh more. It's something the F8X doesn't have, so I hope we don't get any people in here crying the AWD G80 is heavy. Yes, it's heavy, that's why people who like lighter cars would do anything to avoid AWD.

150lb is probably optimistic. As I posted in the G8X forum, AM&S weighed their test F82 6MT at 180lb lighter than the “light” spec G82 6MT featured in the BMW weight video.
