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.

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.

swagon, FWIW adding also this marketing to the conversation: published by BMW M on Sept 17, 2020 (source: here - German version):


'Claim to fame' or 'claim to shame' ? Maybe some soul-searching might inspire BMW M to do a humble reset 'back to basics':
