    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.

    This Engine is a killer. It is already available here in Qatar with the G65 and soon in a week or two in the SL65

    Why would they put a V12 boat anchor in a car that they are trying to take weight out of ? Do you even think about things before you post them ??

    I'll take that bet. I have $10k USD that says if and when the SLS BS is released it will NOT have a V12. Care to put your money where your mouth is ?

    Not enough room in the SLS for V12.. it seems that the SLS designed around the M159 exclusively. Maybe a M157 will do... it will give plenty of room for BIG turbos in the SLS =)

    the SLS has much more room than the SL

    Whatever the BS engine will be. I dont think 650HP will be from a naturally aspirsated engine

    I have good information from a source at the Performance Studio that it will be na - you mentioned a bet before yet seem unwilling to back it up.

    Are you retarded or something ? I know someone in Affalterbach who has been at the Performance Studio since 2006. That's my source - but what does it matter ?? You agreed to the bet already so there's no backing out now. When the SLS BS comes out I'll be looking for my $10g's.
    And what makes you think it will be a MY2013?

    looool. Right you are!

    All you got is BS

    actually you are talking about my 10K. Now how will the loser among us (which is obviously you) will pay up?

    You can send me your phone number on PVT and I'll do the same and lets talk about it.

    God I will love to make you look like an idiot in front of everybody.

    Why is ths motor even made? Is it nostalgia for a V12? The M157 with reworked turbos would move the earth and reverse magnetic poles just fine.

    "With bedplate construction and dry-sump lubrication, the SLS’s M159 naturally aspirated 6.2-liter V-8 is a technological marvel. It’s rated at 563 hp and 479 lb-ft in standard trim, but will make well over 600 hp—perhaps as much as 650—in the Black Series. Mercedes will achieve this not with forced induction, but with internal tweaks. Power will be channeled to the rear wheels through a strengthened version of the seven-speed dual-clutch transmission serving in the regular car.
    It also will be the most appropriate application of the M156/M159 engine to date. Development of this wonderful powerhouse was led by erstwhile AMG employee Bernd Ramler, who in a previous role was central in the development of the Porsche Carrera GT’s V-10. Now, after just a decade in production, the M-B 6.2 is being phased out. Quite possibly the most responsive and baddest-sounding engine ever put into a Mercedes-Benz, it’s being replaced in most new AMG cars by the turbocharged 5.5-liter V-8. But it’s not done quite yet. Hallelujah."


    The only idiot here is you. The C&D link was just to show you that it's supposed to be a MY2014, released later next year - which is exactly what I was told from my source....which is not C&D.
    Regarding payment from the loser - I have no interest to speak with you on the phone. When the car is released then we'll all know and you can pay up.
    Alternatively, we can both wire the funds to @Sticky and he can hold them in an interest bearing account. Your call, I'm game either way - better go ask Daddy for some cash LOL.

    looool. what a moron. yeah now you want to change it to a model year issue. I just put out a model year , 2013. Ok I might be wrong, but that is not the issue here.


    let the SLS come out and we'll see whos retarded !

    I dont intend to wire anything to sticky. Be a man and speak with me and lets see if you can run your mouth like you do here on a forum!

    By the way I am currently Chicago. (sticky check my IP). So your cheap A$$ doesnt need to worry about making international calls. Now enough talking and get your 10K ready
