Just came across this and I don't know what to make of it. On one hand they are notorious for posting wrong figures online. On the other hand, I can't figure out which one has the correct figures, but if I were to guess I'd say the ones from BMW USA News website appear to be correct, although I can't say for certain. If that is the case, it would mean the car is even heavier than we all thought.

The BMW USA website lists the weight of the car at 3,814 lbs for the AT which would mean the MT should weigh about 3,761 lbs. The problem is that the BMW USA News website has 3,814 lbs for the MT, not the AT.

BMW USA
Curb Weight - Automatic Transmission (lbs) 3,814

BMW USA News
M2 Specifications
Curb weight (lbs) 6MT 3,814, 8AT 3,867

Do they give the weight with full tank of gas factored in and all other liquids?

Because I mentioned elsewhere Mischa put the G42 on scales with half tank and got 3783 lbs. So with XDrive and Auto I wanted to understand how that compares to the M2 with RWD and manual.

Don't know, but weights are measured differently depending on region or market. For instance, DIN is used in Germany while the rest of Europe use EU weights. US doesn't have a standard that everyone agrees upon. That said it really doesn't make sense to get in the weeds on that. Point is the weight delta between the M2 MT and AT seems to be 53 lbs more than we thought. That's 53 lbs more than what is advertised on BMW USA website.

Depends on the specs of each car. Base vs base? Base varies in different countries. US has the heavier sunroof base and some places have CF roof as standard. One number could have the CF seats in and the other not?

These are the same figures we have had from launch.

The difference with US curb weights vs EU/DIN.

EU/Germany:
1. Leergewicht EU (Car with 90% fuel, 68kg driver, 7kg luggage (75kg). Latest EU definition uses only driver @ 75kg)
2. Leergewicht DIN (Car with 90% fuel, no driver, no luggage)

USA:
1. Curb weight - weight of car with fluids and fuel at 100% as well as weight of any option expected to be in more than 33% of vehicles sold.

Doesn't matter as we are not comparing each region or country against NA. Specifically focusing on the USA numbers, the car appears to be heavier than advertised.

Seems they listed the same figures as what's on the BMW USA News. Sadly, it appears the BMW USA site is wrong yet again. I can't believe how much this car weighs and it doesn't even have xDrive.

Yeah I think the BMWusa site is a typo.

I thought ticking the box for the carbon package would magically reduce the weight by a few 100 lbs or so

(MT) DIN - 1700 kg (3748 lbs)

(MT) US curb weight - 3814 lbs

If you add in about 40lbs for standard sunroof vs EU slicktop, another 8lbs for 100% fuel. You are within 18lbs of the DIN weight listed by BMW. So, 3814 lbs for US curb weight doesn't seem out of the ordinary. Also consider the US weight could and most likely does include more options. EU also has a more basic seat standard, that is most likely lighter as well. The F87 OG seats were lighter than the M2C seats.

The two most significant weight saving items from the carbon pack is the seats and roof.

Carbon roof -48lbs
Seats -22lbs

Yes, I know they are not apples to apples which is why I wasn't comparing them. Need to put porky on a diet by reluctantly getting the CF roof. I was going to get aftermarket wheels regardless. Will likely get a lithium battery as well.

I wouldn't be surprised if it turns out to weigh less than what specs list much like the G80/82

Weight of the fuel if filled all the way with this size tank would be around 80lbs

I was comparing it to DIN which is 90% fuel vs US curb weight is 100%.

13.7 gall * .10 = 1.37 gallons or ~8lbs over DIN weight. A gallon of fuel is roughly 6lbs.

US curb weight is a black art really. Driver weight is not included in "legal" definition. But most brands include driver in their US curb weights. Then trying to figure out what options would be counted, impossible really to figure it out.

Agree it is a porker. The 18/19 standard wheels from M3/M4 would help.

Oops, read your post too fast. My bad!

[BRAKE!]

To put it into real life context, not going to matter much.

It's a heavy car.

Let that sink in. It ain't going to handle like a Cayman GT4 whether it's 3700 or 3800 or 3900. The brakes, suspension components, other consumables are not going to last years more because it's 3700 vs 3800.

I certainly don't expect it to handle or feel anything like a Porsche, but that doesn't mean you can't make it better. My plan is as follows.

• Get CF roof to remove unnecessary weight up top. Also has an aesthetic benefit.
• Lower the car with a HAS kit or lowering springs in order to retain adaptive suspension. Lowers the entire cars center of gravity which vastly improves handling. Also has an aesthetic benefit.
• Get lighter forged wheels which removes unsprung weight to improve handling and also provides better ride comfort. Also has an added aesthetic benefit.
• Li-ion battery to further lower the cars weight. Still undecided on this, depends on how much the battery cost and will also need a new tender that works with Li-ion. Last on my list since it offers the least gain, TBD.

None of these changes alone will completely change the car, but the culmination of them absolutely will. There will be a night and day difference between it and a stock car.

@Tag spot on man. Exactly what I plan to do. Already got mono-block wheels and HAS kit (from G80) on hand, along with DP.

Sweet. Which wheels in particular did you get? Is this a good HAS kit? https://autocouturemotoring.com/prod...spring-has-kit

What do you think install would run… about $800?

BCF RZ21s. MSS HAS kit. DIY for front springs and paid $120 for the rear. I didn't have enough leverage to loosen the rear bolts from underneath, fronts are easy peezy. Don't pay for then $500 for install.
