rear wing is huge, and diffuser seems bigger compared to the one used on m6 gt3. Considering also that the 3L L6 turbo will be much lighter and less bulky than the huge V8 4.4L TT, I expect this car to have most of weight distribution pushed on rear. Curious to see what will be the bop min.weight since m4 gt3 won't be anymore a 700Nm monster like m6 used to be.

did i see correctly they are aiming to get this thing out for 2022? How much testing needs to be done??? Seems pretty far off in to the future.

That's what I read too. It does seem a long time away.

The point is that the new GT3 regulation should start in 2022 and I don't know if this M4 adapts to the current rules. Also with the new GT3-plus rules in the DTM, maybe BMW plans to race this car in the DTM next year and sell it to customers in 2022.

I think that you are right ...... BMW are taking advantage of the new GT3 rules which mean they are allowed to base the new car on a four door base model - pretty much all of BMW 's new models are based on the same basic design just with different body shells. My understanding is that the current rules (until end of 2021) did not allow this and they had to be based on specific individual 2/3 door models. I might not have explained this in a very technical way but hopefully you get the idea.

Exactly what he said, they applied for an allowance but were denied. The only 2 door platform they produce was the 8s and then the Z/Supra. The new rules allow a shared platform in its 2 door form to be GT eligible. But not until 22, so testing and special invitation events only.

Thanks guys this all makes sense now. I had forgotten about the new regulations starting.

Interesting thoughts on this potentially being in DTM too. Great way to test the platform I suppose.

Also, as it's a customer car, it needs to roll out with a lot less issues than a custom product like an LMP1 does. You're selling this to teams as a product with no major reliability issues. Any update to the hardware will cost a lot.

Did the GT3 cars ever run that much torque in BoP-spec?

well, if you look at imsa or some other bop sheet, bmw m6 gt3 has always a turbo boost of about 1.9-2 bar from about 3500-4000rpm up to 5000-5500rpm....
consider 2 things:

1) a 4,4L x 1,9 bar means in that rpm range the car is like if it had a >8.3L NA engine


2) according to onboards on youtube like this one
https://www.youtube.com/watch?v=5rkGKsptllk&t=291s
despit a bop mandatory 7250rpm revlimit, bmw drivers use to upshift at about 6000rpm, it basically means that max power is released in that rpm range...
to take an indicative and realistic value:
530hp@6000rpm = 630Nm@6000rpm
so since bop can't however bend physics rules, yeah it's really likely that in low-mid rpm m6 gt3 is a 700Nm monster
