When is people going to learn that torque inst everything. Look at M5 E60 , faster than E55. I'm 100% sure that the new E63 is going to be faster than E55.

I gues this is more suited for driving hard on a track than cruising. Is MB trying to change their image?

or mabey they were thinking that they didnt need all of the torque at 1700 revs, but im quite sure... being a 6.2 liter unit, that there is plenty of torque at low rpms.

with the full load of torque, the tires would loose grip, and esp/tc would turn on the brakes to get tracktion back... so, i would say that so much torque is definately obtuse, and mostly unusable at low rpms... especially for an automatic gearbox

I say the TCS is constantly overheating the brakes causing this switch to NA lol.... When u are @ 1800rpm, u couldn't possibly be in a racey mood could u? :roll:

Actually Mercedes has lost some low rev torque in favour of some mid to high revs punch with this new engine. I was quite surprised when I noticed that. Maybe they just wanted to have a different engine character compared to their previous supercharged engines.

(it' of course not the real torque/power curve, but just a marketing version of it, which isn't that accurate)

So what you are saying is that a $50,000+ hand-built Mercedes Engine is a little more powerful than the mass produced $20,000 2-valve, push-rod Chebby LS7 --

i still dont really get this new 63 series from mercedes. seems like it would be a lot more trouble than its worth to produce an entire new engine that puts out about only 17 more hp and 52 less ft lbs of torque (at a higher rpm none the less) than the engine than its replacing. especially from a company that has had issues about build quality.

i didnt see any need to replace the supercharged 5.4L unit. :bah: couldnt they have just tweaked the 5.4L to produce an extra 17hp? am i missing something here?

Chmon Speedkiller you of all people should know that the 63 engine will be turbocharged in a later varient. 8) Unless they scrapped that idea, im still hearing rumors of turbo 6.3 V8.

They finally fixed the 7G tranny so that the engine wont rip it apart. Thats awesome.

The engine is clearly underated, as most Merc AMG engines are. Even the 600 engine is severly underrated. Dont worry this car will be faster than the Current E55.

JiggaStyles09 · 07-16-2005, 01:38 AM

hmmm, maybe they wanted to differentiate the AMG modles more from the 600 series. making them with higher more revving sporting engines rather than low revving torque monsters made for cruising. and maybe they are going to up the displacement on the 63 series and replace the current 65 AMGs with 69 AMG's?

i know thats a really old article and i remember seeing it a long time ago but i was just throwing out ideas. is this even reasonable lol

I think this new AMG engine is welcome addition/replace to the current
engines with a bit more power but with much more sport character that
i'm sure that it has a lot room for improvement in the future.

Some pics of the new 6.3L V8:
