Well they say that because it's the same transmission as the F series and maybe even before that. That has a different power curve.
I don't have it or remember where but someone posted the shift points of manual vs auto and based on the dyno chart the auto stayed at the optimal levels while the manual drops out for most shifts.
The gearing wasn't designed or changed for this platform.
Another point is the torque limit. Generally they give you some leeway with the supporting hardware on the engine. In this case the torque is already maxed out.

Now as for the power and traction. I can always get a lower power amount. I just prefer running ethanol because from what I've seen cars just run smoother with it. You can run more timing which is always better in terms of efficiency. The extra power and cooling is a good benefit.

In any case I will most likely be doing manual for the feel. It's been a while since I've had one and I do plan on getting an AWD car to build with big power so I don't need a lot of power with the M2. I'll see how things are when I get it. I know I'll get used to the power so it's a matter of how long that is before that happens

A side note on traction, I wonder how well BMWs M traction settings help. Like Porsche has really good traction management partially due to the engine layout but when you add power it's still pretty usable.

again, it all depends on how you intend to use the car- i always intended to keep power at stock levels and drive the piss out of the thing. i like a manual in my daily street car and my local back roads are conducive to such a configuration.

if this also describes you... you will not regret the manual.

How bad would I take it in the shorts trading in a low-mileage 2025 for a 2027 XDrive?

Not sure, but on the bright side rates/APR will be much lower, if you do decide going that route.

The Fed has already cut half a point just recently & will continue slashing by .25-.50 every quarterly meeting.

You haven't even gotten your '25 yet and you're already planning on trading it in?

Enjoy what you (will soon) have instead of fretting about the future.

Have you driven a G87 yet? The car is pretty sticky and handles very well for having 460 wheel HP and being rear wheel drive. For sure the AWD M2 is going to be a bit quicker zero to 60 but I think the RWD version does a tremendous job. If drag racing is really important to you there are things you can do to RWD version to improve traction.

Just enjoy the car and don't worry about the far future. Or, if the AWD is what you really want then wait for that and not lose your butt on a trade in.

xdrive is for 0-60 bench racing and that's about it (will probably add 150# or more too) - on a mountain road I'll take the rwd and have more fun

M Xdrive allows for plenty of fun to be had if you choose. Hell, it allows you to be full RWD if desired. The M XD is already very rear biased and allows for as much slip angle as the driver wants. I know most AWD systems tend towards understeer, this isn't one of them. The additional grip allow you to get back on power earlier on corner exit. There is absolutely 0 reason to get the RWD version if getting a comp. If someone absolutely must have the manual, so be it, but outside of that its xdrive or GTFO.

I for one will definitely be ordering an M2X when offered.

If Xdrive is just for 0-60 racing, are the non-xDrive models of the M3 and M4 actually faster around the Nürburgring? (mentioning this track as the benchmark) Does the rear-wheel-drive setup offer any advantage on a track or winding mountain road? Many people say that the RWD versions are more engaging to drive, but I wonder if they’re truly quicker or more beneficial on a circuit like the Nürburgring. Or even a mountain road.

I'm debating whether to order the upcoming M2 CS, which will be RWD, or go with the M3 Competition xDrive. Any insight on which might be the better choice?

Well, I can make it easy for you.
If you aren't in line to get a CS already, the chances of getting one are pretty slim.

I've had my G87 for a year and a half. Tracked a G87 & G82 at the BMW driving school. I can tell you without a shadow of a doubt, you do not need X Drive for performance driving.
I suppose you could use it for like winter driving if you don't want to change tires (which you should regardless of AWD) and if all you do is go straight line stop light racing.
The downside to X-Drive is of course the cost, added weight, added complexity, etc.
Do you want a sports car that you enjoy driving or an AWD car that is fun to drive if you flip it into RWD mode?

AWD is very helpful in cold states, but without an increase in ride height, the biggest danger to this car is high centering in snow (ask me how i know). RWD with snows is more than adequate for 98% of situations.

yeah if you truly can turn it into RWD for hooning purposes without damaging it then there's very little reason not to get a xdrive. I laid down rubber up to ~40mph after kicking the rear end out on a u-turn the other day in the dry, fun but having a rear biased AWD would be nice especially for rainy conditions.

Point in favor of the ZF8 people don't mention enough is that you can grab gears with the rears still lit up (gearbox in 3rd setting obviously), with a manual you're stuck with whatever gear you started with.

The reason not to get an XDrive is because it’s missing a 3rd pedal and hand gear selector. Coming from a bunch of Subarus, a manual XDrive M2(or M3) could be the last car I ever need. Maybe it needs a beefed up manual but damn it sucks that it’s not an option and hasn’t been for some time. I have 2 other manuals so if I ever talked myself into an Auto XDrive it wouldn’t be the end of the world and I could appreciate being able to put down more power with traction over RWD. Traction when modified is where the XDrive will clearly outperform RWD
