One of the purists said no. 🤓 we want optimum performance no compromise. If de driver wants better fuel economy they can drive slower….,or pick from our diesel variant. (Ya gotta say it with an accent and like your slightly insulted by the question.) 🤣 |

Rattles? I didn't even think about that. My S4 in 8 years of ownership was rock solid, wouldn't hear anything rattle except for a buzz from aftermarket exhaust.
Disconcerting! |

I can't comment on the manual part of ownership as i have a comp but i do agree on some of the other stuff.
First off, for my car at least, i only need to hit the m2 button once to activate it. There were times at the beginning of ownership where i wasn't sure if m2 mode was activated when i pressed it so pressing it again defaults back to m1 mode. (i'll test this theory again tomorrow when i drive the car but i'm sure this is what happens if i press it twice). Second, at 4k miles i do have a small rattle. But it's only when i hit those sharp bumps. It's hard to explain but it feels like whenever i hit those sharp bumps, i get a "buzz" type of rattle, almost sounds like as if there's a single coin in your cupholder or something. I feel like it's coming from that area but sometimes i feel like it's coming from the infotainment area. It's not annoying enough to investigate however i know as the car ages with more miles this will get louder and other rattles will pop up. This is a lease so to comment on what was said earlier as these cars seem to be lease and return vehicles. I think that should be the case IMHO. This is NOT a knock on anyone who bought their M car. Everyone has their reasons to lease or finance. However these cars, it seems, gets quite a few revisions as BMW as a brand is known to be up to date with the latest and greatest so i can't see a reason to own this car longer than 3 years. Plus if i did want to buy this car for keep for the long term, it wouldn't be a 1st or 2nd MY. I would at least wait for an LCI to buy for long term. |

But what I should really test is what is the difference in mileage between 5th gear and 6th gear at like 80 mph. Because the real question is would a taller gear be more fuel efficient. I don't think it will make much difference to add one more gear or make sixth gear taller. But now I am curious so I will try and study both. |

Let's just go ahead and remove the cup holder, wireless charging, gesture control, and brake squealing first world problem complaints. If this was a major concern and reason for purchase, then maybe a Lexus or Infinity would be a better option. We buy these cars for sport and performance, not for petty things like above.
The rest, valid issues. Just had to point that out. And by the way, I like the cup holder. Works 100% well in my 6MT.

Oh noes.. I have to press a button twice! LOL C'mon now.. rattles on the other hand are annoying, i haven't noticed any. Cup holders have never been a major design consideration in most BMWs. Remember the flimsy ones in the e90 and e30s didn't even have cup holders. I do have 2 gripes. 1. whenever you use the winshield washer fluid, it sprays onto the mirrors and then pools around the corner of the window and mirror. It's almost like BMW didn't test that in the windtunnel testing. 2. vague steering feel. of course this was a known issue going in with the electric steering and has been this way since the f30 so no surprise there.

If you have a bicycle with gears and a MPH Try and maintain 10 MPH 1 gear lower and 1 gear higher on a flat surface You're spinning your legs faster and more often in the lower gear using more energy Car is no different |

I was reading an article somewhere that BMW was researching the possibility of adding more gears to manual (more than 6), but their challenge was how to make it safe to avoid costly downshift mistakes (aka money shift). I forgot if they discussed details of what options they were considering, but if I am to guess, I'd say with the way the industry is going away from manuals and towards electrification, BMW likely did not invest much in that R&D.
As for taller gears, I suspect they wanted to optimize it for quick passing a high speeds on the autobahn vs fuel efficiency, but who knows!

Because it's tuned to reach 290 km/h at (approximately) max power. The rpms at all the other speeds are the linear consequence of this.

It's also possible that it's influenced by the Euro mileage tests that, from what I hear, have to be done in 3rd gear. Porsche claimed at one point that the very long 2nd gear in some of their manuals was a consequence of what they needed 3rd gear to do for testing purposes.

That's a logical explanation -- and God knows Germans love logic -- but why couldn't you configure it for fifth gear at max power @ 290kph, and let 6th serve its overdrive function? Not all manuals reach terminal velocity with their top gear.

I would add paint quality to this list. First BMW for me coming from multiple Audi's. 4x Audi's and minimal stone chips, my M4 has 5,000km on it and the front is already a mess (and I baby the crap out of it). I'm now putting PPF on it, but a bit late now with existing chips. I expected more resilient paint, a few chips over the life of the car maybe is OK with me, but this paint is pretty crap.

Well, sure, Porsche does have a 7MT option for the 911, though it doesn't seem to get as much love as the 6MT in GT3. Having five columns with double-doglegs (R, 1/2, 3/4, 5/6, 7) does make it a little more trickier to learn and use.

Explanation #1: We agree that lower gears generate higher acceleration than higher gears. That means that when vehicle is in lower gear the wheel applies higher force to the road than in higher gear. That also means that in lower gear the wheel applies higher torque on the road than in higher hear. Therefore if you have the characteristic of the 6th gear in 5th gear, the 5th gear applies lower torque on the wheel and the vehicle doesn't pull as nicely in 5th gear anymore. Explanation #2: P = M*ω P... power M... torque ω... rotational frequency of the wheel The power applied by the motor to the 5th gear at e.g. 6000 rpm is the same no matter what characteristic of the gear is. Therefore if you change the characteristic of the 5th gear the way that you increase the top rotational frequency of the wheel ω (vehicle top speed in 5th gear), you get reduced torque M applied by the wheel on the road. While the max power P applied to 5th gear is the same in each case. |

All I'm saying is, if all else is equal, but fifth gear were taller -- the same ratio as sixth is today -- then the overall ratio for that gear (and hence torque) should be equivalent to sixth today, right?

I just wanted to say that such car would not feel nice to drive, since its pulling force would be low from cca 120km/h and up... Actually everyone can simply try: drive your car normally up to 4th gear. Then shift directly to the 6th gear. (Surely if 5th gear would feel like 6th feels today, they would also adjust the other gears, but you would effectively drive the car with lower horsepower. Why? Because the power of the car that you feel actually comes from the energy of burned fuel; and this energy is the integral of power on the P(ω) chart, considering that in gears with higher characteristic you need more time to reach higher rpm). (yes, I simplified the part with the fuel and let's not get into details regarding correlation of the ω and time, so it doesn't get overcomplicated) |

I know I’m an idiot because I saw that w-looking character and thought of boobs
OP I’ve never seen an X3 on my screen one time, maybe that’s something that can be fixed. Worth a trip to the dealer I think. Also double press on the M buttons is only if your custom settings have DSC off
