From the video:
F82 Comp DCT on 20", likely fully loaded; 1,640 kg
G82 RWD 6MT, 19/20", CF seats, full leather; 1,674 kg
Full tank, which means ca. 59 litres for both vehicles.
According to the data from the press release, a base German-spec 6MT G82 M4 weighs 1,700 kg (DIN, i.e. all fluids, 90% tank). Such car has basic LEDs, HiFi audio, memory seats, 18/19" rims, acoustic glass
Base 2018+ 6MT F82 is 1,570 kg; DCT-equipped is 1,595 kg (DIN). Such car had adaptive LEDs, HiFi audio, electric cloth seats, 18" rims, no DDC, no CF driveshaft.
My maths sucks, but if we compare apples to apples and calculate a DIN weight with empty fuel tank, then their F82 in the video would be approx. 1,596 kg and the G82 1,630 kg.
Base F82 6MT 1,530 kg; F82 DCT 1,555 kg
Base G82 6MT 1,660 kg; G82 Comp 1,685 kg, again all DIN w/o fuel.
Add ca. 10 kg for the standard seats and you're at 1,64x kg. None of the G82 numbers add up. How is this optioned-out car lighter than a supposedly stripper model used for certification... Can't trust them manufacturers with these figures.
Also, I'd like to find out the weight difference between the Getrag M-DCT and ZF 8HP. And no Al fenders on the new car?
All in all, though, a lightweight 6MT G82 is still heavier than a loaded DCT F82.  |
BMW used the term "Leergewicht DIN" on the F8x when the 1495kg curb weight was stated. I believe it was confirmed that this weight was with the DIN definition with no driver and no fuel. Hence the very low curb weights on the F8x, which no one really saw in real life (hence the 1640kg F82 M4 Comp DCT in the video).
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...
