Does the video actually cast any light on the weight of the G8X AWD which many are waiting for? Seems like forum members are guessing based on their personal preferences. Imo, we shall just have to wait. As mentioned before, BMWblog below is a blog favouring BMW.
"So what’s the actual difference in weight between the old and the new car? Unfortunately, BMW M didn’t do an apples-to-apples comparison but the weight difference still isn’t as great as some enthusiasts may have thought. The old F82 BMW M4 used in this weight comparison was equipped with a DCT transmission, while the new G82 BMW M4 had a much lighter six-speed manual. The old car weighed 1,640 kg (3,615 lbs), while the new manually-equipped, rear-wheel drive car tipped the scales at 1,674 kg (3,690 lbs). That’s obviously not a big increase but BMW M did fail to mention something.
The G82 BMW M4 used in this video was the lightest possible M4 possible, being a manual, rear-wheel drive car. When equipped with the eight-speed automatic gearbox, all-wheel drive and the standard seats, the G82 M4 gets actually crests just north of the
1,800-ish (4,000 lb) mark. So, yes, the manual M4 is barely heavier than the old M4 and that’s very good, if properly equipped. But the majority of M3 and M4 customers will get the auto/all-wheel drive car and those cars are significantly heavier (some markets, such as the UK, will only be getting those versions for now)."
