    • Stock C6 Z06 versus stock F10 M5 highway roll on races - M5 wins? WTF?

      This is a bit of a perplexing run video. What we have here is two cars claimed to be stock, A C6 Z06 and the new F10 M5. The two cars do several runs from a roll on the highway from speeds of 80 kilometers per hour (50 miles per hour). The Z06 is just over 1000 pounds lighter than the F10 M5. It does not give up a ton horsepower wise showing around ~450 wheel horsepower stock versus the F10 M5 which sits at about ~60 wheel horsepower more.


      So the F10 M5 makes more power but has another 1000 pounds to carry around. The F10 M5 has also lost to a stock P31 C63 AMG in a roll on race which weighs 700-800 pounds more than the Z06 and makes roughly 35 less horsepower at the wheels than the Z06. So, BimmerBoost is left scratching its head on this one.

      Even magazines routinely get ~125 miles per hour of the C6 Z06 in the 1/4 mile whereas the the M5 is in the ~120 range trap speed range meaning the C6 Z06 is favored from a roll, favored from a stop due to its weight, favored basically everywhere. The fastest 1/4 mile trap speed recorded for a stock F10 M5 is Car and Driver with a 122 mile per hour trap but Car and Driver got 126 for the Z06 so... these races make no sense.

      The Z06 simply has a much better power to weight ratio so why the result is what it is I have no clue. The M5 clearly pulls up top in multiple runs whether it gets the jump or not. Let's just hope F10 M5 owners don't start thinking their car is now a Z06 beater as this will no doubt inflate some egos. From the looks of things though the M6 may have a shot to at least make it a race against the C6 Z06 with how it has shown against the Nissan GTR recently.

      Video is below, you make sense of it.

        What makes you think in those conditions that are obviously affecting the trap speed the F10 M5 would not share the same handicap? Why would it's 120 stick?

        No I am not or that would be 10's at 128 or so right? I'm saying the Z06 is realistically a 124 trap car. The M5 is about 119 or so. This agrees with the power to weight disparity does it not?

        good luck figuring this out bro...there were no conditions affecting the Z other than the car itself; as at PBIR other Z's did manage to trap higher. I figured out bench racing was a way to disappoint and confuse yourself a long time ago...peak whp figures and weight doesn't tell someone an entire story lol

        BTW: There are bolt on Z's that can't trap 128 lol so just goes to show you how much bench racing really matters. I guess they should lake the car since a stock C6z trapped higher? but the numbers? but weight? guess it didn't matter...

        There are results that point to the opposite. I mean I like analyzing runs as does everyone else which is why they are posted.

        No my point was to show you I wasn't taking the highest number and applying it here I was taking a very reasonable average for the Z06. I mean just read my article.

        Do you believe the F10 M5 is faster than a C6 Z06?

        I believe without a track telling you the details (those things required for analysis) that a street race doesn't definitively tell you anything about every C6z vs a M5...I believe it showed you that on the street at this particular time, between these specific cars that the M5 was faster. You are choosing not to believe it

        Again; seen Z's vary in trap widely even stock...don't see why it's hard to fathom a bottom-barrel Z could have taken on a stronger running M5...why is this impossible?

        You misunderstand. I believe what happened in that video happened but am trying to understand why it happened as I believe the Z06 is the faster car.

        Didn't say it's impossible. Maybe the passenger was really fat. Maybe the M5 had race fuel and timing got bumped. I mean I can think of ways to change the outcome of what SHOULD happen.

        I hear what you're saying; all I can tell you is based on my experience at the track and on the street...there are outcomes that don't always add up. Sure sometimes people lie but I have definitely seen results where all parties were honest (cars background are known) and the results don't match the paper work. But IMO that's apart of racing

        Of course and that is why I'm trying to figure out why this particular outcome does not add up. I think we all agree the Z06 is the faster stock car.

        I would say it should have the upper hand in a race yes

        Isn't this true of any race though? I agree that track racing is better for comparing two cars, but not for this reason. Confused

        I feel like a lower factory output Z lined up with a strong factory M5. If they were both truly stock, then how else could this be explained? maybe the Z owner is bad about maintenance and his car needs some routine stuff done to get it back to peak output. With what information we have, it should be left at this:

        Possibility #1, M5 is hiding some mods
        Possibility #2, The Z06 is poorly maintained
        Possibility #3, M build this particular engine well, and Chevy didn't do so great with this particular Z

        Well it doesn't necessarily have to be poorly maintained (possible yes) because not all motors leave the factory identical....especially hand built motors like a C6z. Ever heard the phrase "This motor was built on a Monday"

        yeah I did...I saw you listed possibilities. I just elaborated and talked about which possibility I favored more

        I understand now. I first read that as "you forgot this possibility"

        Stock F10 M5 DCT
        Click here to enlarge


        Jamie Furman's stock C6 Z06 stock tire run.

        Note, in a later video he claimed the car made 455whp what any stock C6 Z06 could make, I however have seen "most" make 420-440
        Click here to enlarge


        Notice the back 1/8th, NOT the front 1/8th.

        The M5 picks up 26.62 MPH.

        The Z06 picks up 26.45 MPH

        Also note, more Z06's are dragging each weekend then all F10 M5's combined to date and they've been beating on them at the strip since 2006.
        Important, no one has ever really replicated the Z06 times, and traps. So this is the worlds 'fastest' being edged out past 90mph

        This. Just wanted some people to read it twice.
