So AMG is still going to be straight line fast only?
I was hoping the next round would turn them into hyper-special variants of their classes like the M3 is to the 3-Series. You can identify a M3 a block away versus a regular 3-Series.
What I'd like is more extravagent AMG styling, more pronounced authority and what not.
But of course, that's what the aftermarket is for right?

As far as people trading in their E55's for the E63... I'd wait as the new E CLASS is due out some time in mid to late 2008.

Aren't the E/CLS motors underrated @ 469hp?
I really hope the E63 is faster from a dig than the E55. MB/AMG shouldn't be moving backwards going to the new engines.

I reckon performance is going to be pretty close ... torque is less but not massively ... the difference is where the peaks are instead of 2500 its now at 5200 its quite a different engine character - even though we have 500nm at 2000rpm which is more than the M5 peak torque!

The only time someone is going to sue a manufacturer is when the cars produce less than the advertised HP. Even then, it's not the gov't that intervenes.
Mazda had a problem with the RX-8 recently where it produced approx 5% less HP than advertised. They offered to buyback the cars, but that was their choice. Hyundai overrated their engines by 4.7% and only offered customers extra warranties. There were obviously class action suits in that case
I have a C5 Z06. It made 363hp at the wheels, bone stock. That's a bit more HP than the rated 405. Almost every 02-04 Z06 I've seen makes more than the advertised 405hp. When manufacturers started voluntarily using the new certified SAE hp ratings, GM's cars were almost universally rated higher by that rating. Many manufacturers ratings were lowered when using the new standard.
I have not dynoed my E55, but it is my understanding that most E55s dyno between 405 and 410hp at the wheels. I also thought that is about the same as S, CL and SL 55s. The E is rated at 469hp and the S, CL, SLs are all rated at 493hp. So did MB underrate the E55 or overrate the other cars using the 55K motor?
I'm not trying to argue, just trying to understand the numbers.

How do they compare? That would tell a lot.

That is a good question. Does anyone have dyno numbers for stock S55, CL55, SL55 VS. the E55?

The Turbo is more expensive than the GT3 and they don't want the HP numbers to be equal. Anyway, the SL and E55 both dyno between 410-420HP at the wheels and 460-480 torque at the wheels.

Thanks for the clarification, Eric. That tracks with what I've read online.
Let's hope MB has once again underrated the E63, because on paper it doesn't sound like it will even match the performance of the outgoing 55K

I'm not too sure if auto manufacters can now get away with HP differences since the new SAE standardized HP ratings went into effect where everyone must report within the same parameters.

Its pretty interesting the HP diffs between the 55K cars ... given the different applications. Exhaust systems are telling ... the E's are probably the quietest and maybe as a result the most restricted across the range and maybe thats where the HP dips. Why they dyno the same as SL's is very interesting. Does the SL also have the restricted intake snorkel that the E's have ? The mappings are different though as the SL torque curve is different think theirs has a slightly narrower plateau ... its marginal though.
So going back to the E63 ... mmm. I think round a track the 63 will be quicker with a better shifting box and closer ratios, maybe also uprated 030 brake setup and CLS 030 suspension mods. Motor for motor I think the 55K is still a better unit for outright grunt vs an unblown 6.3. If they put a Hammer I (light pressure turbo) in the E with +570hp then OK ... great, but I dont think that will come in this W211 but in the next incarnation of the beast, in 2008/9.
Speculation ... but I will still take the E63 for a test as soon as I can and see wazzup.

When it comes to what MB says, I'm more than certain the stated HP is more of a average and less an exact figure - so cars that are accurately DYNO'ed may make more (or less) HP... that is their will be a variance from car to car regardless. The average that MB publishes is likely derived from controlled tests of dozens of cars. I think the key here is they're controlled measurements.
So why are people seeing more HP here? Well, nobody calibrates all these individual DYNOJETS to make sure they're all making equal measurements. Meaning across the nation people are making comparisons using "rulers that may be of diffrent lengths", under different environmental and temperature conditions, using different fuels, etc. Hardly scientific.
As far as the E v. the SL etc. Well the SL has a completely different exhaust system and we know for certain that our K cars can be chip tuned for better performance. I have no doubt the E55 has the exact same HP potential as the SL/CL's but find it very difficult to believe MB would understate the actualy HP of the car in a very competitive marketplace - it just doesn't make any sense to do so.

Exactly, everyone is talking about straight-line acceleration, when where it´s at is a more completely focused package which is good for when the road twists also.

Here's the proof. MBZ fudged the HP numbers on the W210 E55 perhaps to make the non blower S55/CL55 seem superior? Has anyone checked their owners manual for HP rating? The W210 E55 was only advertised at 349 HP. All the non-supercharged W220 S55 and W215 CL55's where listed and advertised at 354 and 355HP. My owners manual has 355HP:

I do know for a fact that it was in 2005 that the Society of Automotive Engineers (SAE) introduced a new test procedure (J2723) for engine horsepower and torque. This was done to bring North American standards in line with what the Europeans have had in place for years. At the time the SAE, whose procedures for rating engine output have been the unofficial industry standard since 1980, said previous criteria allowed automakers too much wriggle room.
As it stands, the current SAE procedure eliminates some of the areas of flexibility in power measurement - meaning it requires standardized conditions for fuel, airflow and engine load. The procedure also requires an independent observer present when engines are measured. While the test is voluntary in the US, engines completing it can be advertised as "SAE-certified". General Motors was first US manufacturer to adopt the new standard, announcing in 2005 that the Chevrolet Corvette Z06 produced 505 SAE-certified HP. MB is also one of the SAE-certified manufacturers.
Most if not all DYNOJETS in the USA do not factor these inputs into their readings and because of this, comparing DYNO results with published manufacturer HP numbers is like comparing apples and oranges.
