I think I'm more nervous about the steering over the trans actually. I've driven the M8 and while the gearbox wasn't as good as the M-DCT I was ok with it however I really disliked the steering and that was a bigger problem for me than the gearbox. But this might be my last chance to buy a 6MT car so....

Unless it is a sequential setup like the 40d and 50d engine rather than electric?

Glad to know I'm not alone wishing for the S58 to get the 48V.
I remember there was a magazine interview on the G87 where the "source" leaks that it will happen at some point of its life circle. It makes sense to me, as BMW is trying hard to pave way for the electrification rollout, the S58 would be a unicorn or wierdo, keeping purely traditionally internal-combusted for the next 7 years. And more importantly, the ZF 48V (gen2, integrated into the gearbox), will hit the market and be used by almost everyone in 5 years - maybe in first 2-3 years by only the top tier makers (Mercedes and BMW). If you look back, 8 years ago, when BMW rolled out the FI, it was so aggressive that we felt like NA was ditched completely overnight. 48V isn't going to add much weight as is. And as the development progresses, it will save weight, because more 48V electronics means more smaller thinner 48V cables replacing heavy thick 12V cable. The S58 is a very laggy engine in the X3MC form. Desperately in need for a fix.

This is Permanentmagnetic Linear Contactless Displacement Sensor via SENT. The SENT signal was specified by American automobile manufacturers. It is characterised by its simplicity and works on an unshielded three-wire connection which also transmits the supply voltage to the sensors. The transmission via a SENT signal is digital and relatively uncritical against fault signals. That is because the information content is located in the falling signal edge only, whereas the time between two falling pulse edges contains the information of the nibbles. The value transmitted by a nibble is proportional to the duration between two falling pulse edges. |

Does anyone know if the new Hyundai i30 has the clutch by wire system already? It is advertised with the iMT transmission, which is the name of the new system, but maybe the old manual was also called iMT, not so sure.
If the new i30 indeed has the clutch by wire system, I already drove it and I can assure you it feels just like a normal clutch, I din't notice anything different. My shifts felt quite smooth though, considering the last time I drove a manual was quite a while ago. Maybe that's the reason why. If the new i30 I drove had the clutch by wire system and BMW's solution is similar, there is nothing to worry about (thank god). Regarding the 48V system, I thought Flasch said in an interview that they don't believe the 48V improves the driving pleasure so I guess you could conclude they will not have 48V. Currently searching for that interview to back it up, but I watched a lot of videos about the G8X. Also, Fröhlich said they initially wanted to skip the first generation of mild hybrids and start with the second generation which offers over 30PS of extra power. They thought the first generation with the measly 11PS doesn't offer enough benefits. I think they were forced to go with the first generation anyway because of the strict EU emissions regulations. |

All of this is cool tech. I remember having theoretical discussions about electronically assisted manual transmissions back around 2007 before the launch of E9x M3. It’s neat that some of it is actually coming to market, although I can’t help but wonder if they could have greatly increased the lifespan of the MT if it had all come a decade sooner. And good call on spotting this, JTO24 and whoever else called it. That’s a good read, thanks. I’m still not convinced the G8x will completely break the physical link between the pedal and the clutch, but it sounds like it will at least have some type of electric clutch actuation (which as I say, would still be big news). Well, it wouldn’t be the first time an M engine forwent new technology that was rolled out to the rest of the lineup. However, I agree that it’s unlikely to last through to G87 EOP (approximately eight years from now) without getting 48V. |

G8x?
https://www.getrag-ford.com/files/th...ansmission.pdf Think same MT as new Ford Bronco. GM electric clutch system patent: https://pdfaiw.uspto.gov/.aiw?PageNu...id=20180252274 Smart MT explained by KIA: https://press.kia.com/eu/en/home/med...nsmission.html Lots of cool new tech to be explained by BMW.

...and then you've basically got a DCT gearbox with an H-pattern selector rather than 2 paddles. But seriously, as a driver who learned on a manual, I would actually prefer to have 'clutch-by-wire' and a 3rd pedal on DCT for reversing maneuvers and hill-starts. |

When F90 Powertrain was announced, one recurring theme was creep (Low Speed Assistance). I swore up and down it had creep on demand. F85/6 did not have Auto Creep to maintain operational characteristics of DCT. F90 prototypes and pre-retail units did not Auto Creep. Fast Forward... F90 retail units arrive, operator's manual gives instructions on how Low Speed Assistance works and how to activate it. I have yet to find a single production F90 that doesn't have Auto Creep nor a way to deactivate it. |

Auto creep is activation upon brake release. Creep on demand is with throttle tip in on, brake deactivates.
