    • Mercedes AMG twin turbo V12 changes - How the new M279 Twin Turbo V12 differs from the previous M275

      You should all know by now that Mercedes is bringing back the twin turbo V12 with the new R231 SL65 AMG. We originally thought this was just the same old M275 V12 that had seen duty in the previous generation 600 and 65 AMG's but the motor has received some updates along with a new M279 engine designation. The 6.0 liter V12 to reach its new 630 horsepower rating received far more than just different ECU software.


      A multi-spark ignition with twelve double ignition coils is used that Mercedes states provides for a smoother motor and more effective combustion. This also is used in conjunction with a new engine management system.

      The cylinder heads were also revised in order to flow better for more power. The turbos have been changed featuring new wheels and are mated to new manifolds. The wastegate ducts have also been revised.

      Additionally, the exhaust system underwent some significant changes. The catalytic converter system was optimized both for emissions and power. The wall thickness of the exhaust was reduced and the system is now 7 pounds lighter than the previous generation.

      Other parts such as the intercooler, throttle body, and airbox remain the same. The M279 is a nice update to what already was a stout powerplant.

        The only fact here is you are a little pussy and you will make any excuse in the book. But the fact is I did call you and you did not pick up. The call history above PROVES IT. You can dispute that all you want, but everyone here knows the truth.

        Hey Jacob it looks like Top Gear is also reporting the upcoming SLS Black Series to have the same 6.3L n/a V8. Did you see this recent article ?

        http://www.topgear.com/uk/car-news/m...deo-2012-06-18

        "So this would be a good place to start some conjecture, and for that, we hand it over to you, Internet. Your capacity for speculation knows no bounds, so have a watch of the video - and just listen to that glorious V8 - and then tell us what you think a Black Series SLS would look like."


        There is also this video where you can clearly hear the V8.




        So are you going to honor our bet ? I realize this is early and unofficial information not from Mercedes-Benz. But it's pretty clear what motor will be in this car so I'll make you a deal. You can pay me now half ($5000) of what you will owe me when Mercedes-Benz makes the official announcement. And from what I have been told, that will not be too far away. What do you say ? Cut your loss in half ?

        Thats not what I am hearing, according to this articale:

        Care to honor your bet and pay me in half right now?

        So you are basing your opinion on what ONE website has to say. I'm basing mine on what I HEARD in the video I posted above that clearly shows a test version of the SLS BS with a V8 and it even has an RL as a chase/support vehicle.

        I think my source and the video posted above is more credible than your single article. What you posted proves nothing. Here are other more credible articles that say the SLS BS will have a na V8:


        Car and Driver - much more credible that your "Supercars.ro" article:

        http://www.caranddriver.com/news/201...py-photos-news

        BBC Top Gear more credible than your single source:

        http://www.topgear.com/uk/car-news/m...deo-2012-06-18

        World Car Fans again more reliable than your source:

        http://www.worldcarfans.com/11206134...pied---not-slc

        AutoGuide stating revised cams and additional weight savings:

        http://www.autoguide.com/auto-news/2...d-testing.html


        Topspeed.com states the V8:

        http://www.topspeed.com/cars/car-new...g-ar89106.html

        InsideLine and you can clearly hear the V8:

        http://www.insideline.com/mercedes-b...s_1205111.html

        Leftlanenews also stating the 6.3L V8 will be used:

        http://www.leftlanenews.com/mercedes...ck-series.html



        Every piece of information available favors the 6.3 V8 and when you look at all the variables involved in making a Black Series it would be silly to suggest they would use the V12 boat anchor in a car that is being derived from the GT3 race car. Anyone with the smallest amount of common sense would agree with me....except for you and your one article. So no, I will not be paying you anything based on your misinformation and I will take that as your acceptance that when I am right and you lose, you will stand behind your word, honor the bet and pay the full $10,000USD. Yes ?

        If I am wrong and lose the bet I will happily pay you and make a public apology here. But, if I win and you do not pay me, I would demand that @Sticky ban you from posting here ever again.

        Im sure that's what you want. It's not going to happen. Have some dignity and apologise now, because you will lose and I don't want your money.

        Oh so now you don't want my money and you want to cancel the bet ?? Not going to happen. You already agreed to it and when I win, I expect an Eric B and Rakim - PAID IN FULL biatch!

        Here's the only apology you are going to get - I'm sorry you are such an IDIOT, Jacob.

        again you are making wording on your own. I never said the bet was cancelled.

        Keep talking. The more you talk, the more I will be laughing at you in the end

        Never said it was. The post above is me quoting you that "I never said the bet was cancelled", which would lead one to infer that it's still on/active.

        I was simply asking a yes or no question, that would leave no doubt or need inference, which I'll ask again.

        Please respond "yes or "no"

        Is the bet still on?

        As far as I'm concerned YES it's still on. I was simply trying to be nice and give him the option to concede his loss early, save face, and save $5000. I guess he wants to play the hard way - fine by me as the outcome is obvious.

        But I think there needs to be some consequences if I do win and he doesn't pay up. What do you think would be appropriate ?

        I think Sticky will agree, if either party would not follow through, a BAN should be given, IMHO.

        Considering the level that this issue has taken.

        Agreed - and I would split the winnings; half to GermanBoost half to charity.
