    • Press ringers? 2018 Mercedes-AMG W213 E63 S takes the F90 BMW M5 from a stop and roll

      All the latest press for the F90 generation BMW M5 has it blowing everything away in a straight line. Magazine trap speeds show 129 miles per hour and the latest sedan comparison had the M5 coming out on top against all challengers.


      So how do you explain what you see in the video below?

      The E63 wins despite a worse start from a dig. That implies it is also stronger from a roll. They go again from a stop and the E63 gets a better start and pulls. Unfortunately, the people at CarWow don't know how to properly drag race so we get no trap speed data.

      They do a roll race next but for some reason put the cars in standard modes and wait for a kickdown of the gearbox instead of having the cars in the proper gear to begin with. It's infuriating how stupid this is.

      The roll race is close but it is difficult to know if this is because of the time wasted waiting for a gearbox kickdown. They do not provide any supplemental data because this is a mediocre automotive outlet at best.

      CarWow states the cars weigh the same but they get this wrong. The M5 is significantly lighter by just under 300 pounds. This means that Mercedes-AMG is heavily sandbagging output.

      Someone will have to get a dyno overlay of the two for us to really know what is going on.

        Sticky, check out that C&D comparison you link. They ran the E63S on 91oct, while others were on 93oct. When the two cars were within a tenth of a sec and 1 mph of each other. That could make up the difference for sure.

        There is a F90 M5 dyno on other forum, not entirely impressive. Although on a mustang dyno, I expected more...471awhp, 509awtq.

        I didn't realize that. They shouldn't have done that but it could explain the discrepancy if they even tested the cars in the same conditions and didn't just do a mashup of data.

        I was pretty shocked when I saw this video over the weekend. The result didn't add up. I would like to see a rematch from a different channel along with some data.

        Hmm I expected more as well.

        I don't see how it is doing 129 on the strip then.

        Something isn't quite right. That's less power than a 991.2 Turbo S.

        We all know that Mustang Dynos read lower numbers than others, also and this is most important EVERY dyno reads differently it's all based on how they have it setup. A best comparison would be one dyno and get a c63s on it and the f90 and see what happens.

        To a degree but that's why we have correction factors.

        That's what I'm trying to make happen right now.

        A comment on that thread suggests that output is artificially limited until the car receives the first required break in service. Something re: software/coding

        FWIW (probably not much Click here to enlarge) I also spoke to a buddy who recently underwent training for the F90, who also confirmed that output is limited until first service.

        Keep the m5 rather the amg wagon.

        That virgin in vehicle dude did 0-60 in 2.7 and 2.8 seconds vbox verified in his e63s on a random street/ unprepared surface

        The m5 has its work cut out going up against that brute. Good thing the modification scene is more with the bmw.

        Like many in that thread, I am calling BS on those claims. That rumor was around for F8x launch, turned out BS too.

        There was also talk of a "press tune" back when the F10 M5 launched? I am not sure, but I think it was debunked.

        The car jerked pretty bad off the line @ 0:36, and @ 1:36 when they tried it again.

        im not sure the guy knows how to launch the car, maybe traction control was kicking on or he didnt have the right MDM mode or whatever.

        Not smooth launches at all.

        doesn't explain the roll racing though...the merc is strong up top!

        Yeah, and it was BS...every F10 M5 that's ever been timed has been able to equal or beat magazine times...there's plenty of bone stock F10 M5s that have put down incredible times on Vboxes and on drag strips.

        And just like the F10 M5, I wouldn't trust any dyno numbers early on for these cars either...not sure how any claims it's "BS" that these cars aren't limited during their break-in period, as far as I know they absolutely are...you have to take it back to the dealer so they can reprogram it, in fact. At best, I'd say the press cars are obviously not running in "break in" mode, as that would be dumb, as dumb as this stupid drag race with kick-downs.

        Also, the F10 M5 knew when it was on a dyno, and was very picky about that...took a while for good dyno runs to be had with that car as well...same thing is happening all over again. This remains the only time I've seen an E63 go quicker than an M5...may not be the last, but I guarantee you there's reasons behind it. A 3 mph trap speed difference is not insignificant...in fact it's a reasonable gap.

        The F90 just made 569whp in 5th and 592whp in 6th on a dynojet

        There is no additional power ‘unleashed’ at the 1200 mile service. I never did that service on my first F10 and it ended up
        makkng the most power to-date on a stock motor.

        Exactly.
