Yep true ... forgot the dreaded heat soak ... !!!! In Europe so far have not had occasion to experience it yet with this darn cold winter.... will see how it goes in summer.

I don't see why that is so telling, the old N/A AMG 5.5L V8 only made a brief (underpowered really) appearance in the flagship models. The turbo version of the new 6.2L will take care of any hp/tq worries.

Obviously in the SL/S/CL the na 6.2L would be slower than the old SC V8 because of the torque shortfall.

It took a 7 speed tranny to shave 0.2 sec from E55 times from 4.7 sec to 4.5 sec 0-100kph, just as it did for E500 when it adopted the same gear box and 0-100kph times dropped from 6.1 sec to 5.9 sec. Wow!!! That's what I call a massive gain. My E55 does 0-100kph in 4.4 sec stock.
The 7-speed tranny is a PIA as it keeps hunting for the right gear up and down, even with a V8 engine. Forget the low down torque of the E55, this one will rev right up like a screamer and stay around 3500-5500RPM if you want any performance.
This is all to save a few pedestrians from smashing their stupid brains out against the supercharger under the hood!
Nobody cares about being run over by the Suburban or any other monster SUV...
All the styling changes on the E63 are pretty useless, including the pointy grille like a Honda Legend or a Mazda 6. I guess if they can copy the 7 series BMW rear end in the new S-class, they can copy a Japanese grille in the E-class.

couldnt figure out how to cut and paste but they are out on http://www.mercedes-amg.com/

check tech specs/ performance diagram for G55(same as e55) vs E63.

the scale is incorrect for the e63 they have not changed from e55 data but peak is 630 nm /5200 rpm.

notice how much more power the e55 makes down low. compare rpm points 2000, 3000 up to 5000......the e55 is making more power below 5200 rpm or so then the e63 takes off.

BoBcanada

I dunno why most of you guys kinda hating the e63 here, i think it is gonna be improved and fun ride to drive!

stevebez

I find the fact that they not introducing the 6.2 motor in the SL/S/CL class telling because they find the 55K motor beter in the interim... until as you say they come up with the 6.2TT. Now thats a different movie.

The lower torque of the n/a 6.2 on these heavier cars could also be a factor.

... thats exactly my point.

Rgds Steve.

AWDman

very roughly based on the hp graphs on the amg site

at 2000 rpm the e55 makes 187 hp the e63 147
at 3000 rpm the e55 ------ 295 ---------- 214
@ 4000-------------------394-----------348


anyone see the recent european car article on e55? the supersprint system gave ~50 hp this may be how MB choked down the e55 vs the sl55 (493hp)?

not hating just sometimes newer is not necessarily better (referring to the engine in this application- lux car)

BoBcanada

dont forget that e55 has 5 spd and 6100 rpms only so no doubt it will hit everything sooner then E63. But once e63 hit its magic zone 7 spd will keep it there and it will be faster then e55!

AWDman

Bob -quite right.

6500 rpm for e55 but party's over at 6100. agree gearing is the winning factor...would love to see the 6.2L engine in the slk -something lighter more sporty....me personally i'd prefer the e55....with a chip and exhaust....loafing along the highway...with a 550 (or more) ft/lb torque plateau 1000 rpm to the south and 2000 rpm to the north.

I'm a bit spoilt i guess as i have my lil red screamer (8500 rpm) to fill a certain viod !

still looking at 911 TT?

BoBcanada

Who me?

I looked at 996 turbo sit in one it was way too small for my fat a$$

I really like the e63 now, gonna wait for the acceleration data and some tests, test drive 1 and see, looks like a very nice car

let's not go over board and think the E63 has no torque. It has more torque than any other Super Sedan out there.. V8 n/a or boosted. I'm talking from the factory not mod potential.

STS-V, M5, S6, S8, RS4, Maserati, S-type R,

The E63 will still be a torque monster compared to BMW, Audi, Caddy and however else wants to bring down AMG.

It will not be the 55k BULL anymore, it will be 63 Stallion.

7spds and 465 torque.. is plenty to keep almost everybody happy ( except 55k or v12 owners)

LET's also remember what the M5 really shines at, 0 to 150 and handling.

Now the 0 to 150 advantage will be gone and the M5 will remain the handling king as always, and the E63 will be the 0 to 60, 1/4 and 0 to 150 king.

Things will be back to normal and the UNIVERSE will be peaceful!

BoBcanada

so if M5 does 0-150mph is 20.3 seconds e63 will do it in? My guess would be 18.5 !

i know new Z06 does it in 17!

MidniteBluBenz

That new 6.3 looks sweet. I don't remember the last time Benz produced an engine that showed 8 grand on the tach. That badge on the fender's got to go though.

BoBcanada

You know why? Coz this engine wasnt produced by BENZ, it was completely made ny AMG devision!!! And the badge look ok to me!

stevebez

So what we got ?

new seats (wow!), new (real leather) steering wheel - this we could probably retro fit to the E55's, active brake downshifting, better steering ratio and response, better suspension setup with semi-active air suspension (is that new?). SBC is gone (?) - replaced with electrohydraulic braking system (sounds SBC rebranded).

Down side ... lost ~50ftlb of torque ... not a bad trade off in the end or what ?

As may have been said before this 6.2l has more torque at 2000rpm than the old E39 M5 had at peak - not sure how much the new one has ... surely thats enuf ?

But for me its not a big enuf change to get me to exchange my '06 E55 yet. Will test drive asap ... if its an absolute blinder - maybe. But I will, for now, hold out for the W212 6.3TT in 08/09 - IF the new E63 will get the H1 blown motor - if not I will keep the 55K and go kleemann route.

Both 63 & 55 w211 cars will depreciate as fast when the new shape emerges so why bother going to the 63 now for 10% more than the 55?

Rgds Steve.

TopGun32

18.5 would be a agrressive number..

i would say around 20 secs... just in par with the M5 or a bit better due to its 80lbs +/- torque advantage.

So now, from a rolling, from a dig, top end, it will be the fastest car out of the Super Sedan world.. (again excluding V12's or Ultra Super sedans or modded 55k)

I would guess that a stock 55k engine at certain speeds will be able to pull away from the E63, it would not be able to pull away completely. Eventually gears 4, 5, 6 and 7 will be just too much for the E55k stock motor to beat.

Another guess/estimate would be that gears 1, 2 or 3 will be all E55, but after that it will be all E63.

We won't know this until we have a test mule ala GUSTAV's videos when the M5 came out..

BoBcanada

well i would desagree here. Both cars capable of doing 0-60 under 4.5, E63 does have more hp and you know what they say HP win races, we're talking stock to stock, i think from the roll e63 gearing will win extra 50ft of e55 trq.

I guess we'll just have to wait and see. I wonder how long we have to wait till some magazine will put their hands on E63.

Germancar1

I don't see what the point is here. They're waiting until the turbocharged version is ready. Just like before you will have a naturally aspirated version and a boosted version as with the outgoing 5.5L AMG V8. The only reason the SL55 got an updated version is because the new 6.2L V8 wasn't ready yet. No big deal. They clearly don't find the old 5.5L motor "better" because they aren't using that engine any any newly introduced products only the existing SL, not the new S or CL.

GTA7.5

The face-lifted E-Class models (including the E63) are all equiped with what MB calls Direct-Control. Thay say the Chassie is much more responsive and the steering has been quickened by 10%.

The Airmatic suspension is also said to be improved.

ClayJ

Just a slight clarification: they are minimizing the use of the 5.5 SC'd because of the new pedestrian safety regulations/standards -- not because it is better or worse than the new AMG 6.2L NA.....

This engine (the 5.5 SC) will still continue to be utilized in certain models -- at least in the near-term.

I think that they are both fantastic motors, period. I also think that the new 6.3 NA, when coupled with the new 7-speed tranny, will not leave much to be desired in an AMG powertrain....

E55Freak

Has anyone ever thought that they reduced the low end torque to reduce the wheels spin off the line? It may get a better launch and then be able to kick the high horsepower in? I could be wrong.

BoBcanada

Very good point!

Germancar1

This is true, but the real reason is that a SC V8 is harder to update in order to pass emission regs. They could have designed the car around the engine if they wanted to use the 5.5L SC in the new S/CL, but they didnt. The new V8 is going to be much cleaner and slightly less of a gas hog. Though I will miss hearing one when they go by.

Hey Rafal! come across any M5's on the road lately up in sydney?? any runs?
We saw a new one on a flat back rolling into BMW HQ the other day... here they come~

Vetluver

All this talk about how fast these new cars are reminds me of reading medical journals. When discussing whether something is statistically significant it must be tested making sure that the conditions are equal.

Car testing is anything but scientific. Errors and differences abound.

My point is that jawing about which car is quicker, faster, better handling etc is nothing but garbage. We need to get out on the track and truely get the numbers. I'll bet they will all be great fast cars which will depend on the best driver to get from point a to point b.

Until I get passed by something other than an E55 I'll bet on my blown monster every time.
