I think that in order to be apple to apple you need to subtract both fuel and driver (75kg) when comparing to the F8x Also, according to the definition on mass in running order for Europe optional equipment is not included. This means that in your calculation you need to subtract 10kg from the 1660kg since tha car has the optional CF buckets (not add 10kg for the std seats) and also subtract weight loss for CCB (if the G82 was equipped with that option, which it probably was since he stated it was a "light build"). And then the weights start to add up for the G82... BMW probably was a bit short sighted when they claimed the "sub 1500kg" curb weight of the F82 and using a dry weight with no driver. The F8x was actually heavier in real life and, as it seems now, not that much lighter than the G8x. But BMW managed to create a hype around the F8x being more lightweight than it in reality was it seems... Which now comes back to haunt them whith the G8x and use of conventional definitions on curb weights (wet weight w/driver). So now, BMW spins it the other way with showing that the F82 really wasn't thaaat lightweight... - Last edited by Boss330; 01-11-2021 at 12:23 PM.. |

When they say lightest configuration did that include CC brakes? I could not tell? On the G82?

Ah...good question. It’s always something tricky in there isn’t it... But I suspect the CCBs require the 19/20 wheels or larger. I.e weight chasers can likely get to similar weight with steels and 18/19 setup. Last edited by solstice; 01-11-2021 at 04:16 PM.. |

This is a good first step in explaining some of the technicalities, as long as the G80 doesn't weigh more than my RWD M340i I am pleased. I will never get a fully optioned car anyhow so that should also keep weight in check.

DIN weight, as I eluded in my previous post, features a car in running order with 90% fuel and no optional equipment; EU/EG-Leergewicht weight adds 75 kg to that number. That means there is no need to add 10 kg (standard seats) to the 1,660-kg "base" M4. If 1,630 kg is what an M4 weighs with buckets, then you just add ca. 10 kg to that figure and you've got a car with standard seats. I did not see CCBs in the video, it is possible it had them; no argument here. BMW Deutschland use EG-Leergewicht in their brochures. Standard equipment varied a lot on the F8x M3/4 which is why I highlighted some of the standard German features. Some markets got manual seats, base iDrive without sat nav, etc. However, it is safe to say that BMW high-key pulled a Ferrari on us with the original weight figures of the F8x. Somehow the DCT lost weight over the years, too. 03/2014 (all DIN, 6MT/DCT) F80: 1,520/1,560 kg F82: 1,497/1,537 kg 01/2015 (Competition Package) F80: 1,535/1,560 kg F82: 1,515/1,540 kg 09/2018 (OPF, no CF driveshaft, non-Competition) F80: dead F82: 1,570/1,595 kg Head hurts from these numbers, am out.

The curb weight stated by BMW is for the car with std seats. That means if you option CF buckets (and steel brakes) you can subtract 10kg from the stated curb weight. If you order with std seats (and steel brakes) the curb weight is as stated. |

The video was talking about all of the weight saving and at the end it weighed more?? Couldn't figure it out....
Terrible voiceover - at least mute the German which at times kicked in!

Most weight savings are vs the standard 4 series as CF roof, removing sound deadening, aluminum doors and hood. The CF seats are vs the standard G8X seats. The crank shaft...no idea but I hope it’s vs the X3M. So nothing is directly vs the car on the other scale.

That the car is “in part” faster than an M4 GTS when wearing cup tires is somewhat eye-popping. Sub 7:30 Nordschleife time or is this the part where it’s not faster...? Guess we need to wait another couple of months to know what he mean here.

For reference and to compare apples-to-apples, Auto Motor und Sport weighed their 2014 6MT M4 test vehicle at 1,592kg, which translates to a 82kg / 181lb weight increase 6MT to 6MT.

there is a reason they did intentionally not compare apple to apple here (F82 comp vs G82 std)... The G82 was in lightest spec possible on purpose, we could see it had 6MT and carbon seats and i'd also guess CCB... so if we were to take a comparable G82 comp with ZF + normal seats + possibly normal brakes that's probably at least another 60 Kg...

Looks like the G has full leather as well, and both have HUD too. Assuming it has exec pkg from that, not sure if HUD is available separately in other markets. I took his comment (the translation of it, anyway) about a lightweight configuration to mean 6MT + the seats, not that it didn't have any options. I guess a definitive apples to apples is still TBD, but it's a nice surprise to see this come in sub-3700 lbs. Was expecting 3900+.

So this G gen M4 with Steptronic (horrible memories) sits at 3745lbs according to BMW.
If true, that's not bad at all. That's approaching Alfa G Quad mass with more power.

Happy to see that after all these dragonball teenage crap videos, M is finally willing to go into the real important stuff. Nevertheless, very suspicious when you see the extended time it took them to come up with this, while this had to be a clip at launch time and that they compare different specced vehicles. What are they hiding?
A second elephant in the room remains the turbo threshold <2700rpm, maybe they will release a clip about this within a couple of weeks? |
