Lol, I'm in that boat. I love my 6MT, but damn if i'm not jelly of the AWD people now. I just need to keep telling myself it's all about the experience

[Chang24831]

Wow, 3.07s… This M is a beast

[mjbernatz]

Very impressive. Thanks for making my wait even more painful! Seriously though...thanks for sharing.

[SeanWRT]

Congrats to OP!

1/4 mile please!

If you are not going to drive in snow, it's a mixed bag of pros and cons. Extra traction is a pro if drag racing, but how many people do that? On a road course it will help coming off the corner but it adds a few hundred extra pounds which has a real impact on track and on consumables too. And handling will feel different unless you turn off the stability control completely and have just the rear drive; but then you still have extra weight.

Can you use the 10 stage traxtion control in rear drive mode with xDrive?

Yes, you can use the 10 stage traction control on xDrive model when in RWD mode. However, The car has to be equipped with M Drive Professional option.

I'm in Seattle - we see snow and a lot of cold, wet weather too. When it was relatively new, I managed to unintentionally oversteer on my 300hp/tq RWD 435i GC, and only a lot of corrective steering and a lot of luck allowed me to come to a stop without hitting anything.

Granted I was running summer tires in wet, cold weather, and I immediately bought winter tires after that, but that baseline, and being unable to push harder without risking oversteer in similar conditions fed into my decision here.

I've staggered PS4S on the 435i and in ideal summer conditions, it drives like its on rails - the best I can get is brief squeaks on acceleration and low squeals in corners. And then I have the rest of the year to contend with.

On a 300-400-ish car, I'd be okay doing RWD again. Not on something BMW rates at 503 hp. I know two people who totaled their last-gen M3/M4 within the first two years of ownership. The decision for me seemed really straightforward all things considered (consumables, driving feel, etc., I'm knowledgeably say I'm okay with). The cherry on top is the 0-60 times being reported here.

Wow! Can’t wait to get mines

If specd with CCB it's easy high 2.8

it adds 100lbs over the RWD only car. I'd you spec CCBs and CF buckets it weighs 1lb less since CCBs are 80lbs lighter, buckets are 20. 3979lbs (stock) vs 3880lbs M4 Comp of course the RWD one could be 100lbs lighter too spec'd the same but you get the point. AWD isn't the huge weight penalty people think.

It's more about power loss transferring to front axle.

A good example would be 992 4s, which is noticeably slower than its RWD counterpart outside of drag from dig, indicated by trap speed and 100-200/60-130 time.

We'll see what kind of trap speed OP got with 1/4 mile. That would be a good indication.

Gotta get me one of these!

Mine will have them.

I don't know if they will allow it to go under 3s. I don't think so. 3.3 will be really impressive for instance. Even the 3.5 officially claimed is a really supercar run time.

[Limegrntaln]

What people seem to forget when they talk about the AWD, is, you're probably not getting much power loss, if any at all. This car isn't full time AWD. Its AWD when the rear tires start to slip. You're carrying no driveline loss at speed. And I wouldn't dock the AWD for the driveline loss while in AWD, because any drag it creates, it makes up for by getting you to your goal quicker. In this case, much quicker.

This is why I waited for the AWD. I see people posting about, "why do I need AWD, I don't live where it snows?" That answer scares the shit out of me. If you don't understand the performance benefits of AWD, and only see it being used for inclement weather, you should probably be driving a Prius.

isn't a rwd car always better than an awd version of the same car? in terms of driving dynamics?
awd adds weight to the front = more understeer ??

Or you could just share your “expert knowledge” with them rather than go all, “I am a graduate of the Grand Institute of Snobbery” on them.

OP is quickly burning through his ~100 launches. Curious to see if that's a real thing and if his acceleration times drop off eventually.

Also, I'm already starting to sense a RWD vs xDrive war. Can we not, please. We are already having to take shit from everyone else in the automotive world (especially other BMW owners) - let's not divide ourselves from within. Same team.

But no doubt, these launches look very aggressive. Impressive.

This is with a draggy, which has proven to be very accurate.

Wrong. Even when decoupled from the engine, all of the AWD components still need to rotate, generating friction loss and inertia drag in the process.

[whatnotsomuchf80]

all the AWD haters just don't understand, once you highly tune the G8X, you need AWD. My F80 is constantly slipping and that was the only reason I didn't go full 900whp build. AWD solves that issue. Past certain torque levels, it's just dangerous and inefficient to have RWD
