My guess is that the next M3/4 will offer the manual transmission (actually with hill holding and auto rev matching it is becoming a semi-manual transmission but at least it will have three pedals) and the 8AT and the DCT will be dropped.

That's a good thing. My M3 has a sunroof and it makes it very hard to find a workable seating position when you have your helmet on. I wish it had sunroof delete and I now see why E46 owners always talk about that option. But I guess the new M3 will likely be bigger - so maybe more headroom, but a helmet really jacks things up in some cars.

Makes sense... its like trying to integrate a VHS player from 1983 with RCA outs into a state of the art home theater system

The stock powerband is completely fine for a 6MT and lends itself well to that transmission. In the N55 and B58, the powerband is such that you get the sensation of power building as the rpms close in on 7000rpms. I've calculated the ideal shifts for a stock N55 MPPK, M2 N55, and B58 and they're right around red line for optimal acceleration. Additionally, the 8AT shifts at or close to redline as well. BMW would have revised shiftpoints if they thought the powerband was dying on the topend. News flash, it's not. When you tune these cars, the naturally-aspirated like powerband that BMW has designed in gets neutered a bit. The powerband elevates massively in the low to mid-range rpms and the peak power shifts downward. Instead of power peaking in the 6000-6300rpm range, it's more in the range of 5400-5800rpms. The powerband also dies out more dramatically above 6000-6300rpms. Essentially you make the turbo BMWs behave like a rabid pushrod Ford 5.0, meaning lots and lots of low and midrange power with reduced breathing in the upper rpms (due to the limits of the turbo). Even then, the 6MT is more than up to the task to deliver driving enjoyment and performance. With the 6MT, you do get some perceivable lag when first mashing the gas, but that brief lag makes the driving experience a bit more exciting comparable to that of the 8AT which feels almost CVT like due to all the gears, instant shifts, and lack of much, if any, torque shock on the shifts. Also the torque converter which can unlock under light to moderate throttle, providing in sense even more "gears" between the real gears. BMW also has worked some wizardy where some boost is maintained between full throttle shifts with the 6MT. At full throttle, my M235 maintains 5-7+psi on the shifts depending on the gear. Yes, the 8AT extracts the most performance out of these motors; however, "better" is the opinion of the driver. For some of us, faster and quicker doesn't necessarily equate to better. |

As for who you replied to, the N26 is known to have a more pronounced falling off towards the end of the range in comparison to the N20, and I have read that is due to the more constrained Cat.

the difference that you can't compare a dyno chart with throttle response on a turbo car. when you shift an N/A car, you pick up exactly where the dyno reads at a given rpm. when shifting a turbo car, the line changes and you start from a low power/torque point and it builds as boost increases.
so when people say they want linear response, you can't get that from a turbo car. the boost increase is linear, but the response is not. you have to wait for the torque. but i love turbo cars for the same reason i love manuals. i like feeling the boost/torque build on every shift. |

And the latest gen of turbo definitely does not have the same raw feel as the surging power band of yesteryears. If one wants to feel fast, but not be fast, at least get the old school M54(e.g.) N/A and have some fun with MT. Thinking that the latest gen turbo + MT can feel fast is also a farce. |

The F30 is not revolutionary, much less so that a manual transmission is no longer viable, sorry to disappoint you. It can't "feel fast"? I'm certain there are countless people with countless "fast feeling" turbo manual cars, including many on this forum, that would vehemently disagree. IMSA F30 328i #81 & #84. Six speeds. http://www.bimmerworldracing.com/84-bimmerworld-328i/

And comparing N26 MT to N26 8AT, N26 MT feels flat and cannot shift faster than 8AT, while N26 8AT feels flat but is fast. |

Technology progresses whether we like it or not. AS ATs and DCTs have gotten better and better many drivers who have driven MTs for years and who are very adept at driving MTs have made the switch.
At this point in time I own and regularly drive cars with MTs, "Conventional" torque converter ATs and DCTs. I enjoy driving all of them and if there was one I did not enjoy driving I would get rid of it. They are all fun to drive in their own way. Driving the MT Miata is a very different experience than driving the DCT M4 but they are both very engaging. The DCT and AT cars in a sense give me the best of both worlds. I can put them in "set it and forget it" mode and let the cars decide when to shift, and when I do they are almost intuitive about being in the right gear. Or I can put them in manual mode and shift when I want to shift. There is a lot more to high performance driving than shifting gears. If you do not think so than I challenge you to take a "self driving" DCT or AT car to your local track and sit in the car while it sets a track record all by itself.

If I was into setting lap times and winning money, I wouldn't be caught dead with a manual. However, in all other none racing situations, the auto will not deliver the same engagement and driving joy as the manual. Period.

In motorsports, as in most sports, the majority of the participants are not winning money, they are spending money. If you are serious about track driving, whether you are racing or just lapping, and you are using 100% of the car you are 100% engaged regardless of what type of transmission you have and the objective is to get around the track as fast as possible. I enjoy driving my MT cars and I also enjoy driving my AT and DCT cars. They all have their good points and their bad points. AS a road car the Miata is a blast to drive and I would not want an AT in that car but the M4 DCT is also a very enjoyable road car although a very different driving experience.

ill make sure to let my GM know to pass along the message that dropping the 6mt will lose them at least one future sale.
