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 is with 90% fuel, no driver and no luggage...
US curb weights are a bit more complex.
In depth look on curb weights in this thread back from when the F8x was being introduced:
US Curb and EU Kerb weights, an attempt at clarifying the differences.

From commission regulation (EU) 1230/2012 on masses and dimensions:
https://eur-lex.europa.eu/legal-cont...02&from=EN
Quote:
(2) 'standard equipment' means the basic configuration of a vehicle
which is equipped with all the features that are required under the
regulatory acts referred to in Annex IV and Annex XI to Directive
2007/46/EC, including all features that are fitted without giving
rise to any further specifications on configuration or equipment
level;
(3) 'optional equipment' means all the features not included in the
standard equipment which are fitted to a vehicle under the responsibility of the manufacturer that can be ordered by the customer;
(4) 'mass in running order' means
(a) in the case of a motor vehicle:
the mass of the vehicle, with its fuel tank(s) filled to at least
90 % of its or their capacity/ies, including the mass of the
driver, of the fuel and liquids, fitted with the standard
equipment in accordance with the manufacturer's specifications and, when they are fitted, the mass of the bodywork,
the cabin, the coupling and the spare wheel(s) as well as the
tools;

This means that the EU curb weight is with all std equipment, but not any optional equipment.
So a base M3/4 curb weight in EU is heavier than if you spec optional CF bucket seats and CCB. So in the case of the M3/4, adding options can actually decrease the stated (EU) curb weight. Which is what we probably saw in the video.
