Hammer Down

After reading that the 2007 SL55 comes with 510hp and 531ftlbs of torque!
I feel like they have cheated all of the 55 owners the last 4yrs. WTF!

Does anyone know what the MAJOR differences are between that motor and ours??????

xxaarraa

Dude why would you feel cheated?????? Its normal for car manufacturers to upgrade the motor's performance for subsequent years.

I would feel cheated if I bought an 07 S55 and it had the same output as an older E55 !!

Torquey55

The only time I feel cheated is when I go to the MB dealer and they bend me over the service counter and they screw me without lube.

I don't know for sure.
I've heard that it's just different ECU tuning and I've also heard that it's a better, more efficent supercharger.

This has been discussed in numerous threads in different forums. Based on their press release, they're spinning the S/C faster, using a larger throttle body, and tweaking the ECU. Nothing major - just small adjustments.

Can Drive 55

I suppose that using that logic, anyone who bought anything in the past ought to be chapped off because the new stuff is newer and better. Now I am really pissed that I bought a new 1950 ford flathead V8.

I would not feel cheated, the E55 is one of the fastest sedans in the world, and can be made even faster!

A 2006 Dodge Magnum RT station wagon can outrun an old 70s/80s Ferrari 308 GT. Wonder how the Ferrari owners are feeling.

i would feel cheated if i bought an 02 E55...during 2002...and then boom..the 2003 E55 comes out with over 100 HP more.......
I always thought of how 2002 E55 owners felt when they heard the news of the "new" v8 kompressor engine coming out the year follwing....

Now THAT, is something to get pissed about. I'd feel more "cheated" about the ECU reflashes that all you 55k owners are getting slapped with so Mercedes can make a car with a mediocre improvement in power/speed look like its had a major improvement in power/speed. I'm surprised you guys arent storming the effing gates regarding that one.

BlackC230Coupe

Yeah, i was going to say the exact same thing. I would be kicking myself if i missed out on the Kompressor.

I think the people that should feel the most cheated are the ones that bought the w220 S55 with the normally aspirated engine and then the next year the w220 S55 came out with the v8 kompressor.

no engine difference, just exhaust and possible programming adjustment

TFKompressor

i'd bet if you dyno a stock E55 and a stock 07 SL55, they'd come within 10hp/15tq of each other...

newton22

Same with the 600s. 2002, nice powerful V12. 2003, KAZAM, V12 with two turbos!

Schiznick

I have read in a couple of places that it is a different Kompressor. One of the magazines has a picture at AMG of the Kompressor with a tag on it that showed that it was the higher output model.

My vote is for upgraded Kompressor and ECU tune......

I also have to say that all this talk that MB is flashing ECU's so that the E63 will be faster than the E55 are dreaming......

Can you imagine the lawsuit that MB would be in if they were caught doing something like this? I just don't see it happening.

With that said, I don't doubt that they are making changes to the ECU's and that may make it more difficult for us to tune them. I look for Kleemann and Renntech to fix this for us. I don't think that it is MB's responsibility to test that all the tuning software works with their ECU upgrades.

Just my .02

From my notes on the new MY2007 SL55:

....The SL 55, on the other hand, will receive a few more enhancements, including a higher-speed supercharger compressor and a larger throttle valve. The result is a power boost from 368 kW/500 hp to 380 kW/517 hp and an increase in peak torque from 700 to 720 Nm....


....The enhanced AMG 5.5-litre V8 supercharged engine at the heart of the SL 55 AMG is equipped with a new, higher-speed supercharger compressor and a larger throttle valve to optimise the fresh-air supply. In addition, the installation of an even more efficient engine management unit has boosted the output of the AMG V8 powerplant from 368 kW/500 hp to 380 kW/517 hp, while the peak torque has been increased from 700 to 720 Nm....

The electronic engine management now features cylinder-selective pilot control of the firing angle: this function sets the optimum combustion point individually for each cylinder, resulting in a further improvement in the efficiency of the AMG V8 engine....

The SL 55 AMG Facelift
....Technology:
-Uprated AMG 5.5-litre V8 supercharged engine with an output of 380 kW/517 hp and a peak torque of 720 Nm

-AMG SPEEDSHIFT five-speed automatic transmission with new torque converter

-Steering with more direct ratio, including new valve control logic and modified elastokinematics at the front axle

-Second-generation ABC

-New AMG high-performance composite brakes at the front wheels....

Quite a few changes, I think -- and all good.

Now the question is - in this E55 forum - what of these were also done on the MY2006 E55 -- and on the new MY2007 E63?

TFKompressor

P/Ns on the 06 E55 supercharger unit is 113 090 02 80. Same P/N for the 06 SL55...don't know about 07 though...

regardless of mb's reasons and the notion that you "don't see it happening", it HAS happened. i agree, mb has zero responsibility to test compatibility with tuning software. however, and contrary to your misconception, ecu upgrades are not the point. a huge part of the problem is that owners of BONE STOCK vehicles now have a significant decrease in power/performance.

prsmith777

I only feel cheated on the price I paid for my 2007 SL55 with 030 Performance Package.

I didnt have the chance to really feel its power last week when driving it...still under the 1000 mile break in period.

Kev04C320

F-that break-in period. AMG cars are meant to be driven hard from the get go

JDM

I feel cheated cause I didn't get an e55. But it's my own dang fault. Dangit.

Heisenberg

No reason to feel cheated just because AMG boosted the output of the 2007 SL55. If you envy the new model's increased HP & TQ, it is easy enough to raise your 55K to that level or significantly beyond with one of the aftermarket solutions. While this isn't cheap to do, remember how much less expensive the AMG CLS55 & E55 are compared with the SL55.

Now I would feel cheated if I just bought a 2006 CLS500 or E500, and the 2007 model has basically has the same MSRP yet with 25% more HP & TQ without any hit in fuel economy The CLS550 & E550 may be great platforms for bolt-on superchargers, time will tell...

They're probably feeling pretty good as they park their classic 308's in their garages and getting in their F430 F1's....

TAKE THAT! Silly Station Wagons.

1 Word..... Upgrade!
