    Re: AMG 6.3 engine shots

    Thanks for the shots

    Who in their right mind would compare an AMG motor with a GM one?

    Anyways, FWIW, this motor weighs 199kg dry and is an exclusive AMG development, the M5's 5.0L V10 weighs 240kg.



    Re: AMG 6.3 engine shots

    Output is output.

    Shockingly, a Vette LS2 motor weighs less than a 993 engine by about 50lbs and has more output and revs to the same
    cutoff point as a 997 engine.

    Vette motors win races. Porsche GT1 motors win races.
    What AMG motor in a production car wins anything????

    I guess I dont have a right mind!

    Re: AMG 6.3 engine shots

    Jim,

    Mercedes and AMG motors are tested to the absolute limit. They are taken to the extreme climates of the Earth and tested with every concievable load/weight combinations and nearly countless hours of bench testing with differing variables. These engines are built to last and provide the same power output for years to come. The AMG products are offered the same factory warranty as any other Mercedes product, for this reason alone, the mere thought that this 510hp engine is as reliable/trusted to be reliable as a 150hp run-of-the-mill Mercedes diesel garners respect. I have more confidence in such motors than equivalent output motors from any other manufacturer. I know reliability means nothing to most people, but I personally feel, the quality of efforts from across the pond and the quality of the subsequent cars produced are reflected in the price at which those products are offered.

    Re: AMG 6.3 engine shots

    I aqree that AMG engines are some of the best made in the world. Not only do they look nice, but they perform well.

    As for the quality of the cars they are in, even the recent board meeting of Daimler questioned that. When it comes to
    reliability surveys, Mercedes Benz's very low ratings do not match their very high prices.

    Re: AMG 6.3 engine shots

    Touche

    Lately, however, their newer products are returning to quality and from all the reviews and in-person encounters I've had with the some cars, this seems to be changing (A-Class/SLK/CLS/ML etc.)

    I guess it takes a certain person to have faith in a brand to return to become what it once was

    Re: AMG 6.3 engine shots

    What are the advantages/disadvantages of high displacement engines like that of the corvette/viper vs. a high revving engine like that of a Ferrari, I've allways wondered this.

    Re: AMG 6.3 engine shots

    Well, personally, the Viper's 8.3L? V10 is just too much. The main advantages of a high displacement V8/V10 is that you have an abundance of torque and more of it low down, which translates into effortless acceleration. However such engines in probably the majority of cars are not good at maintaining their torque output at higher engine speeds, save some products from GM, eh Jim? The low torque outputs at high engine speeds results in lower redlines, which is overall very good for engien longevity, however, but a high revving motor >7000rpms is beneficial because such engines can be allied to very close ratio transmission (if you have one) and give scintillating performance.

    This is not to say that a high displacement motor cannot do the same, however generally with a lower redline you are forced to use slightly longer gear ratios and therefore the end resulting performance may be equal/slightly better/ slightly less better than a high revving/close ratio concept (see E55 vs M5 saga in most recent guise.)

    High revving motors require lower displacements so the pistons have less distance to travel. Such motors although very small, they are able to rev more. Concomitantly, with the correct cam proifles and other associated engine hardware, they can sustain and keep producing good torque well into higher engine speeds. This results in a high horsepower rating. Horsepower as we all (should) know by now is a calculated value, yes not measured. Torque in ft/lbs X revs / 5252 gives you the power output for a particular engine speed. High revving motors NEED low displacement engines (in most cases), however such engines suffer from a low torque rating. You may look at the M5's V10 and laugh at its 520NM compared to the still-in-production AMG Supercharged V8 with 700Nm+. However, the AMG can't sustain its torque at high engine speeds, but the M5 can sustain most of its little torque at high engine speeds. As you will see from the horsepower equation, the only way to get power is to increase torque or to increase revs, increase both and you'll get a monster!

    Regardless, any engine, no matter how good will fail if left wanting a good transmission.

    The transmission of any car is basically a torque-multiplier. You may have seen gear ratios for many cars, the best way to think of them is the ratio multiplied by the torque of an engine at any speed is the actual torque being sent through the transmission to the wheels, save the natural power losses through the driveline. The transmission can make or break any car, it is that important.

    High revving motors have very light pistons and flywheels for quick and free revving, ever tried the throttle response on a 360 or GT3 or even the ultimate CGT? Such motors have little torque and therefore need high ratios to multiply their output into REAL KICK! High ratios mean the engine will need to be a high revver or the engine will run out of revs, so the two go hand in hand.

    Low revving motors do not need such drastic @assistance@, they are already producing adequate torque and as such don't need that many ratios (5/6 are satisfactory) and don't need to be short either. The end result is that these motors will have similar performance to equivalent horsepower high revving motors again, see the E55 vs M5 battles.

    Personally, I much prefer a big capacity V8 to a 4 or 5.0L V10/V12, revs are not really the best thing for engines although see Honda Vtec success. The noise alone of an AMG V8 is enough to send an audiophile like me, yes AUDIOPHILE, not what you think and definitely not an Audi fan, to buy such a car. Having high torque is a must for any car, an engine is fundamentally handicapped if it does not have a good transmission, thankfully we don't live in such a desolate world, therefore you can make high revvving motors with very little displacement and high horsepower and max the crap out of the transmission and you will have a fast car (F430).

    I seem to have gone a lot off topic but I'm sure Carlos/Grant/Jim and others will fill you in on engines more sufficiently than myself and correct me also, provided they get tempted into the darklands of the AMG forum.

    The more displacement, the more power.
    The higher the redline (and adapted engine set-up), the more power.
    The higher the forced induction (super- or turbocharger), the more power.

    The smaller displacement, the lower gas consumption.
    The smaller displacement, the lighter and efficient the engine.

    Just a ROUGH sum-up! It all depends on how big the explosion in the engine is and how efficient it is used. That's all those engines are set for, some better and some worse. It all correlates with gas mileage, pollution etc.

    Just as an example, the modern direct-injection diesels common in Europe are that efficient that they don't generate enough heat to warm up the cabin - you need an additional heater in the system for the winter! Since diesel engines have a general higher efficiency than gas engines they gain a better gas mileage.

    Jim,

    I don't want to disagree with your comment but the 993 engine is still very related to the flat-6 engine in the very first 911 (901). I am not sure if I would compare those engines. I am pretty sure that the new water-cooled engines are lighter, besides that it is of course less complex to build an aluminium push-rod V8 - which doesn't mean that I dislike the result in the Corvette. This engine is a similiar win of engineering over concept as the 911's rear engine layout is.
    Anyways, I would still choose a 911 over the Vette.

    In fact I would be curious to know how much parts the LeMans-winning Vette shares with the production car.
    AMG and HWA, the new-established company by AMG-founder H.W. Aufrecht, developed numerous racing engines for and with Mercedes, e.g. the DTM-car's 4.0-V8.

    Regarding Porsche it is a fact that the GT2, GT3 and Turbo's engine is a DIRECT derivative of the racing-version! That's the difference.

    Well, after reading many, many posts on mbworld entitled "it's all about the torque anyways" and "Mercedes can't build a good NA engine" not to mention the countless hours spent deciphering the multitude of mathematical and physics equations that some forum members posted about work and time I decided to learn myself...and it seems to have worked

    Interesting, but I think they need to look into Oldsmobiles success with hi revving large displacement engines.

    Is 8500rpms from 7 liters enough?
    ...



    Yeah, but if I get it right it did not make it into production, did it? So MB is still the first to do this...

    The reason Mercedes is declaring it as a 6.3 litre engine is their reference to the 70ies' S-class with 6.3 litre-V8 (W108?)! That car was faster than the majority of sportscars.




    Sorry but Porsche is the first with a high revving, large displacement engine, sort of. One of the 3 928 parts suppliers has created the "WHITE CAR" by boring out a 928 engine,

    It produces 550 hp and 485 ft/lbs. Officially clocked at 210 mph.
