its fast, not as fast as a proper 6-2 heel toe downshift in a manual, but faster than the outgoing zf6

To OP, the real problem is not the transmission (ZF or GM doesn't matter) but the throttle response and the associated programming. I have seen comments in reviews that the response on ZF 8-sp. is still programmed for economy. This is why a company like Burger Tuning released the PBX. I bought one for my car and no more lag related to throttle response. It does its job. I also drive most of the time in DS/M mode which helps. Last edited by Saintor; 01-07-2012 at 09:10 AM.. |

Drove both, ZF 8 speed is faster shift times, anyone that drives both can tell the difference.

The 8 speed 'box shifts far quicker than any manual.
However, at least BMW have sorted the manual out now, it has been 5 years since this awful clutch and flywheel has been about, and they have only just sorted the design out so it changes how a manual should. I say buy which one you prefer, the auto 'boxes are so good now that they beat a manual in performance terms on level, so really just a case of whether you feel like a race driver or some other shit by having a manual 'box. |

That well might be so, but in my F10 535d with the same box, I'm just too busy enjoying the seamless gear changes in 'sport+ mode' and what with looking where I'm going, I just don't have time to operate a stop-watch .
OP, you can look at all the raw facts detailing fractions of a second that are impossible to count, but be assured that the 8 speed auto is one hell of an efficient transmission. |

this is why i prefer a manual. for me its not about which transmission is .0000 sec faster, I have fun driving 0-80ish and with a manual I can get much more enjoyment from the acceleration than just pressing my foot down and having lighting fast shifts.

As for the 8-speed, I have it in my Audi A5 and I really doubt there is anyone here who can shift faster with a manual transmission. There is one caveat though. it shifts really fast in S and even D; hoever, there is a distinct delay when using the paddle shifters. I have no idea why it was programmed to act this way. |
