Natural. How will it go compared to M5. Exciting mmmmmm

Specs released:

Naturally-Aspirated V-8 (90-degrees)
4-valves per cylinder
6208 ccm displacement
Max power: 510 hp (380kW)@ 6800 rpm
Max torque: 464lb-ft (630Nm) @ 5200 rpm
Redline: 7200 rpm

Will the hurting never stop?! Over sixhundred (600!!!) horsepower for a new 6.0 liter biturbo. Those horsepowers are crazy ouich

As stated in one of my threads, the M5 actually have 520 - 530 horsies. I believe its gonna be a close race, maybe M5 advantage because of aerodynamics in 100+. Mercedes will be faster from 0 - 100.

Edit: Plus I doubt Mercedes will make a gearbox which switches as fast and I doubt they will squeeze 7 gears into it.

My 2 cent :M5thumbs:

I'll be very interested. I assume it'll be Automatic tranny, so I imagine that even though it has minor torque gains, they may be negated by that fact.

Fairly high redline too... following in BMW's footsteps?

Haha amateurs, they are still a 1000 rpm behind :haha2:

It will probably get the new 7G Automatic

Merc has that 7G tronic box out so maybe they will put that in ?

 

[MortenDK]

With adjustable shifting speeds, just like the M5? Because they can't make a super fast gearbox if you don't have that for a luxury car. :1:

It's nice to see BMW are on speed with technology (can't spell that in english, sorry )

Most interesting to me is that MB seems to be moving away from forced induction and following in BMW's footsteps. The engine is nowhere near as sophisticated, using displacement and torque to make up for high rev's. My guess is the car will be heavier and the drivetrain less efficient. That would make the rwhp to weight ratio the same or less than the M5. Bottom line is it will certainly be comparable to the M5 in straight line power. It doesn't sound like it is anywhere near as well engineered though.

And of course there's the handling...

 

[MRichmond]

Also interesting is that accompanying a 41 hp increase in horsepower is a 52 ft-lb decrease in torque. In addition, this maximum torque now will come at much, much higher RPMs. While 464 ft-lbs still is a tremendous amount, the shift in philosophy is notable. It will be interesting to see the reaction of the AMG faithful, who largely expected higher horsepower numbers and always lauded the E55's huge torque at lower revolutions.

Isnt it possible that ML63 get 510hp and E63/SL63 get like 20 extra horsepowers?

I cannot read the articles, so I don't know. What we do know is that on the current -55 models, MB rated the S55 and SL55 at 493 hp versus the E55's 469. The engines are identical and the difference reportedly comes from differing exhaust systems. Many speculate that there is no difference and that the different ratings simply exist to support the significant price differences between those models. If this practice holds, I expect that the E63 (if that is what it will be called -- a somewhat awkward nomenclature) will have slightly less horsepower than the much more expensive SL63, but that the engine will be the same.

Bi-Turbo-V8 mit 600 PS ab 2007

Bwahaha.... I find it funny... because this is gonna be one monster engine, especially when KLeemann will be done with it, do you think m5 will raise hp on the m5?

 

[Mardeth]

I doubt that the M5 can raise its own hp but the K.I.T.T definately could! (Sorry for being a wise *** ).

I also doubt that BMW would raise the power output in the M5 but they might actually just change publiced numbers to the real ones...

Diminishing returns. MB's 65-series cars have proven to be very marginally, if at all, faster off the line than the 55s due to traction and greater weight issues. Once rolling, the extra power will be more noticeable. Also remember that the 65-series cars in the US cost significantly more than twice what the expected cost of the M5 will be.

 

[Taipan]

M-B is not moving away so much from forced-induction, but they are moving from superchargers to turbos (A200 Turbo, V12 Bi-turbo, V8-Bi-turbo and of course this is because diesel has tought a lesson about turbo making a better economy etc vs supercharger, and I do know that a supercharger has its better things too..) ,and at the same time making better NA engines..
the old V8s are not 4Valve construction, and now they are moving to that.. same as they moved in the V6 department

huh? the sl55 is a 12.5 car driven by myself. same driver :15: in the sl65 gave 11.5 a few weeks back..

make no mistake - at least the sl65 (dont know the other 65 cars) is much faster than the sl55/sl600 cars. i know that for a fact.

regarding the new flavor of mercs- we will see. unless they do something for the weight/suspension/gears, a high-rpm engine will not be suitable.

I was referring to shorter acceleration runs, like 0-60, which have at least some relevance in real world driving. As I mentioned, once rolling, the extra power does matter. Quarter mile times are relevant only for dragstrips, but the distance is long enough for a difference to appear.

 

[AJ]

dont agree. the twentyfooter is criteria for launch. my best time with the sl55 was 2.05 and 1.82 in the sl65- both on stock tires. the sl65 also does launch better. more torque down low= better launch. if i had slicks, the difference would've been even more pronounced (once you hook up and you are below 5000 rpms- torque is all that matters...)

actually, i think that the sl65 on slicks is a flat 11 car...

[MEnthusiast]

I think the comparisons, while entertaining, are not that meaningful because both make lots of power and they do it differently and have packaging that causes a different driving experience. Anyway, thanks for the info- that MB engine looks pretty sweet!
