what really worries me is the long term reliability of the so called new technology turbo engines, just had bad experience with chronic issues on other turbocharged cars.

As I said in a previous post; Turbo cars tend to have longer gears since they often have a broader useable rev range than a highly tuned NA engine. With your love of turbo cars, I'm sure you appreciate that...

Which is also part of the uninspiring racing sound. When you start your gear run at 2.5k rpm instead of 4.5k rpm it will sound a lot lazier and boring accelerating out of a curve indepedent on what gear you are in or how long it is. Welcome to torque racing... Let's face it, it sucks from an audio excitement point of view compared to a NA screamer but the power will be impressive and there still seem to be a nice top end to explore. And this chassi...oh yeah.

I was hoping more aggression in sound department.

Flippin M6 does 110mph in 3rd......and yes it has a nice flat torque wave to make that work, but boy does it make the car boring!!!! (for a 560horse M Car) I have a feeling 6th and 7th in M3/M4 will be a wasted gears too. all for an extra 3 mpg |

I'm pretty confident that I know what I am thinking
Tell me what frequency you would hear from an I6 @ 8000 RPM. Any idea? I'll give you a hint: 400 Hz It's actually pretty easy to correct for the Doppler effect and estimate the RPM given that we know the engine architecture and vehicle velocity.

Check out the video at 3:07
1. Try to match the frequency of the observed sound which I estimate is around 350 Hz. 2. Figure out the speed of the car away from camera. It sounds like the top of 3rd gear which should be around 90-100 mph depending on gearing. 3. Correct for Doppler effect. Easy if you can Google. http://www.wolframalpha.com/input/?i...400Hz%2C+90mph So again, it sounds pretty close to 8000 rpm. It's way better than a guess.

The sound of the F82 M4 will never compare to the E92 M3 (I don''t mind as much) so let's just stop complaining about it. Though, at 1:07 before the mini Karusell, it sounds like a vintage screaming I6.
I'm all for pushing the envelope of technology so long as the driving experience that BMW has given us is still there. Just look at Porsche with the new GT3 (highly probable to be next car) and the outcry from loyalist over the PDK, EPS and RWS without even driving it yet the actual driving reviews say otherwise. I say let us judge the car when it comes, then we can talk praise/criticism.

NISFAN: As is typical with a final drive modifications one here for the M4 will help some performance contests and hurt others and when considering results say on a strip or track across a wide variety of gears overall it will be a wash. There is no such thing as a free lunch and altering a FD ratio simply does not give one a single speck more power and that is what matters.

everyone is complaining about how weak or burpy the stock exhaust note is.
because the exhaust note was so perfect on the e92 that no one went aftermarket... have you guys not heard the f30 335i exhaust by meisterschaft let the aftermarket men do their work! i am as much excited for what the brands can do to this car as the car itself.

For info the M6 does 40mph in top gear, that is a theoretical 288mph geared speed. Tell me that wouldn't benefit from having a shorter gear set? Furthermore anyone who supports the fact that turbo's provide significant lag, will also support that there are occasions, like coming out of a corner, where there isn't boost, and therefore torque to carry a long ratio......just teasing on this one |

If you're in the M5/6 you could probably spend most of that time in 3rd with all that torque. |
