Yikes! I hate when dealers do that or are slow to act. I hope you get you get it all squared away. I'm seriously looking forward to seeing the M4's and M3's in the dealerships.

And apples to apples means same track, same day, side by side. Ideally back to back with the same driver, but similar experienced drivers side by side would work too. Gustav needs to make more videos. |

My point was, a bit of a rolling start (not as much as 60-70) is enough for the m5 to put in a few bus lengths. |

This will be my last post on this subject until we have more testing results than an amateur running on a sandy bended road, 100 pounds of equipment on board, and calling it a valid undisputable comparison. Absolutely the information, data, and videos UAE has provided have been awesome and not intended to take away from his awesome effort but lets keep it in perspective.

BMW USA right now says this for 2014 M5: "Conquer every road with the M5 Sedan. It's armed with the most powerful engine ever outfitted in an M5. A high-torque, 7-speed M-Double Clutch Transmission makes going 0–60 in 4.3 seconds routine." For M3: "In the spirit of true M racing, you’ll enjoy a 0-60 mph time of a mere 4.1 seconds, dropping to 3.9 seconds when equipped with 7-speed M Double Clutch Transmission." The difference is a substantial .4 seconds between the M5 and M3 using DCT by BMW conservative estimates. Actual Magazine testing for M5 have been in 3.7-3.8 range or .6 difference which is also quite substantial. Now with M3 working with 3.9 to begin with as factory metric who can honestly say that it would be impossible to see a 3.6 as CanAutM3 has cited in his data or even lower and shock the car world. Lets wait for proper testing to see what we get. My bottom line is this: The f8x is faster in 0-60 and on any track, twisties, canyon roads with exception to high speed expressway driving. In everyday driving conditions with the average joe at the wheel it will be easier to extract performance from F8x than and F-10 in 99% of driving scenarios. The M5 would certainly outperform the F8x in speeds approaching 100mph and on midrange pulls that involve speeds over 100mph as it should with the advantage of added HP. The M5 is a lot of fun when playing at these speeds and no argument here The reality is that we would only ever see this on an expressway / Straightline driving situations with room to spare. This is why the last E9X generation was often quoted as the best all around performance daily driver out there. I have no doubt the F8x will follow.

That time I got was when I had my M5 100% bone stock, with Charcoal Filters too. But it was in less than optimal conditions as people might say around here. I did it on top of a mountain back in San Diego at around 6,000ft elevation and there was some dust around so who knows.
With my modded M5 currently around 750hp and 650tq, my 0-60 time is actually slower due to traction issues. That's why Greentrbo95gst had to put DR's on, because no AWD.

This is why AWD in next generation is going to happen. The M5 will see huge gains in performance and track and the weight penalty makes it worthwhile when greater power becomes useless. I did not realize you had modded up to that level We definitely will have to do a drive sometime and swap cars to do some comparisons

I mentioned much more than 0-60 and track. Everything but expressway cruising/midrange high speed pulls is included in the bucket. I also did not cite a M5 CP but the F8x will have the same results with closer outcome. To be clear do you think that either a M5 whether or not it has CP will beat a F8x in a 0-60 sprint or around a track in a head to head? Think carefully

Power (peak) to weight is what matters and the cars are virtually identical. The performance observed for the M5 is consistent with a mild underrating, perhaps 20 hp, not a massive underrating. After accounting for very close power to weight ratios the next observation is that the shape of the power curves matter and in this regard the M4 (even though personally I don't prefer the character of its power band) it is a slightly "better" curve, i.e. making a higher percentage of peak power across a wider rpm range.

No, I have corrected your statement in bold.
Again, no, there is nothing about the preliminary data nor the matching simulations that indicate this. Sorry, it just isn't the case. 60-130, yes quite decisive win for the M5, anything similar or above the same.

You missed the point completely that comparing a modded car into a conversation about stock performance is a mute point. Ok back to my coffee

maybe that coffee would benefit from some adderall I digress though thats what I'm doing to my M4 is modding it as much as possible I'm happy with what this VBOX data showed and hopefully this engine has just as much potential as the 63tu. Hopefully downpipes and quality exhaust systems fix that awful, awful sound. |

Nobody is doubting the race track. But as i mentioned before in this thread, this thread is about vbox which is straight line speed. So please stop saying M3 will beat the M5 in a track, sure it will. But this conversation is about straight line speed. And in a regular day to day driving, you never do launch controls, you never floor in traffic in a red light. You do mid range 30-40 mph pulls. Thats it. If I wanted tracking, I'd get a GTR or a 911 4S. M3 to me is a compromise car it does each (track, dd, etc) 80% of the way whereas M5 does dd 100% (it is the best super sedan in the world, there isnt a better car), and to me I'd much rather get a car that does track duty 100% as well like a porsche or a GTR. Obviously that costs significantly more money |

Have a look at post #6 here : http://f10.m5post.com/forums/showthread.php?t=962214
This particular member got 563hp on wheels, that is around 662hp on crank. That is over 80hp. |

Dynos are like religion, they all can't be right. They are inherently inaccurate, non repeatable and poor at establishing absolute values. Do M5 CP's trap at 125+ mph? I'd be included to believe something close to your claim about the power if so, if not, no. Anyway, isn't this side discussion really about the M5 BASE vs. M4. Obviously a more fair competition would be the M4 with similar factor mods, of which I'm highly confident BMW will offer.
