    Another rumour of new V8 engine....

    http://forums.mbworld.org/forums/showthread.php?t=90490


    570hp....for the 6.3 V8, can anyone confirm this?

    Re: Another rumour of new V8 engine....

    The performance version (ie biturbo) of the new 6.3L V8 will be used by the McMerc P8 (if it gets the nod from the MB board) and the N/A version of the engine will replace today's supercharged 5.5L V8 engine.
    The bi-turbo version of the engine is being worked on by Rolf Zimmermann and Bernd Rambler, Rambler was the designer of Porsche CGT's 5.0L V10 engine. Zimmermann was THE MAN that oversaw the development of the Kompressor V6 and V8 engines.

    True?

    The name of the Carrera GT engine designer is Bernd Ramler.
    And I think there is some sort of confusion: Bernd Ramler worked for Mercedes and changed to Porsche a while ago.
    So I honestly doubt he has something to do with the new engines in the pipeline.
    Rolf Zimmermann is the chief engine developer of AMG, so it is very likely HE was indeed involved in development of the new engines.
    I heard that one engine version used for AMG delivers around 560 HP. The new ML63 AMG should deliver in the 460 HP range and it will have impressive performance because it is also rumoured to be around 100 kg lighter than the old ML55 AMG.

    Sorry for the mistake, apologies.

    Well, all rumours at this stage, I've heard 500, 530, 571, 600 and now 560hp, don't know what to expect really, hope its faster than the current models, and sounds the business!

    Bernd Ramler moved back to Mercedes-AMG at 2004,July !
    He`s the new "Director Powertrain"
    It`s true .

    Hello RC,

    Have you heard any rumors about a Bi-Turbo V8 (new 4 valve, Direct Injection engine) and what the power levels might be?

    I read somewhere that the HP #'s could be around 700hp, is it possible? Enquiring minds want to know.

    Re: Another rumour of new V8 engine....

    I have doubts. After finally learning the REAL importance of Hp/torque, I can deduce, that the new AMG V8 engine, with 6.3L and IF N/A, will NOT produce 571hp...

    See, the reason is (briefly), HP is derived FROM torque. It is the ability of the engine to SUSTAIN the torque it produces over its RPM range. You can apply 200lb/ft of torque to a wrench, but could you do it 3000 times a minute? Thats what a car engine does.

    There is an equation:

    (HP desired X 5252) DIVIDE BY Peak power point ( in revs)------> Gives you the torque required at that RPM (peak power point) to produce your engine's power....

    Therefore, lets see, we would like 571hp from this engine @6500rpm, so:

    (571 X 5252) / 6500rpms?

    EQUALS ----461lb/FT!

    The engine must produce that much torque at 6500rpm to get 517Hp out of it. NOT POSSIBLE, we already know of the engine's max torque of around 600NM/442 lb/Ft. How can it produce MORE torque than MAX torque at higher revs? It can't. Therefore, the engine IF N/A will not produce this much power (571hp).


    The engine CAN produce more power whilst still staying N/A, if it REVS, and it will need to rev HIGH. BUT, the 5 / 7 Speed/autoboxes have a rev limit of 7000rpm. By inputting 571Hp into the equation and using 7000rpm as our peak power point, we get around 428lbft at 7000RPM, that is simply impossible given the max torque rating.

    Now, if it is restricted from revving and "only" has around 434lb/ft Max torque, it will NOT produce 571Hp N/A.

    I'm sorry guys, if AMG want 571Hp, they will need turbo's....or a high revver and therefore a new gearbox..
