• Is the new F10 M5 with the twin turbo S63tu V8 underrated? PP-P performance says the car puts out 573 horses

      PP-P Performance put up a dyno vide of the new F10 M5 on their dyno dynamics. The car put down 444 horsepower to the wheels (we are trying to get the graph) and PP-P based on their baseline corrected this out to 573 horsepower. Is the M5 putting out more than the 560 horsepower BMW rated it at? We would think it pretty much has to as the X5M with all wheel drive, less boost, and lower compression is rated at 555 horsepower. The F10 M5 routing its power to the rear wheels through a more efficient dual clutch drivetrain with more boost is likely much stronger. This dyno run is just the first solid evidence we have to prove it.

      Also, keep in mind that BMW is underrating their turbo M cars quite heavily. Just take a look at the BMW 1M dyno results for confirmation: http://www.bimmerboost.com/content.p...eel-horsepower

        So are you saying it's only underrated by 13hp? Kind of a disappointment as people were guessing the whp was going to be closer to BMW's crank figures. Although, does it really matter because the M5 spanks the competition, not only on the track but in a straight line.

        No, I'm saying this is the first solid evidence of it being underrated. By how much I don't know I'm simply stating it is.

        It will take more data for any solid conclusion.

        The WHP is on a dyno dynamics as mentioned, keep that in mind.

        I'm not familiar with that dyno, does it read low? All I really know of is the Mustang is the heartbreaker and the Dynojet gives ya the boner.

        Spanks? This comparo says otherwise: http://f10.5post.com/forums/showthread.php?t=594332

        I'll take the E63 with the twin turbo 5.5L. Only a tenth slower 0-60 according to Car and Driver, 3.8 vs 3.7 for the M5. But the E63 now weighs less and has been reported to have better handling/steering feel. The extra displacement doesn't hurt. Oh and it sounds way better.

        Yes, Spanks! Straight line or track...you go ahead with the one that sounds better. http://f10.5post.com/forums/showthread.php?t=620186

        Plus, the header said for 364 days a year, the M5 is better....after that, I got bored by how boring looking the Merc is...so I stopped reading....what day was the one day, that the amg was better?

        You said spanks.

        But in the comparo the Benz has better numbers and lost the comparo.

        And the M5 is a fat heavy pig.

        Comparo also says this.

        What's not in doubt is the extra handling percision of the Mercedes, or the greater sense of agility it displays when you really start to lean on it through a quick corner.

        If the Mustang breaks your heart the Dyno Dynamics puts a rusty knife through it.

        THIS. I guarantee if you put that same car on a dynojet your getting 30+whp.

        Bogdan, I removed the attachment as I'm writing up a mini-article and don't want anyone to steal the dyno that PP-P sent me.

        Thanks for putting it up my man but I want to make sure BB gets full credit for it Click here to enlarge

        AND, has to have an exhaust soundtrack piped inside the cabin because it is so insulated!

        What that dyno done in 6th? That pull took way longer than it should have.

        Pull may have been longer due to dyno load as well.
