Emailed AMG product manager about my concerns over E63 performance as I have an E63 wagon ordered to replace 03 E55 coming off lease.

Looks like MBUSA will post some comparisons on the AMG private lounge site.

Here are excerpts from MBUSA response

"Like you, we were also interested in head-to-head comparisons of the cars,
both under acceleration, as well as on the track where other performance
characteristics (braking, handling, lateral acceleration) could be
compared.

Basically, the E63 AMG is a much smoother and more linear performer,. For
acceleration, this means that the 0-60 mph times are more consistent and
easily achieved, whereas with the E55 AMG Kompressor, the torque being
available at a much lower engine speed, frequently causing wheelspin (and
ESP / ASR actuation) under hard acceleration. Our tests yielded more
consistent results for the E63 AMG, although in some cases the E55 AMG
delivered a lower elapsed time at the dragstrip.

On the road course racing track we used, the advantage of the E63 AMG was
much greater. On the same day under identical conditions, out pro driver
lapped the 1.48 mile track at 3-4 seconds quicker in the E63 AMG
consistently. This can be attributed to the superior compound brakes,
revised suspension, 7 speed AMG Speedshift automatic with shift paddles as
well as the lower weight of the engine (-47 lb) over the front axle.
Further, our drivers found the E63 AMG much smoother, more progressive and
easier to drive fast.

We plan to show information and other cool stuff from our testing on
Mercedes-amg.com/privatelounge very soon so that you can see the E63 AMG
results for yourself."

The statement from MB-AMG is consistent with what I've always said.

The E63 is NOT significantly faster than the E55 in a straight line. It should, however, perform much better in the handling department because of the Direct Control upgrades to the suspension and steering. (C32 vs C55 all over again)

The E55 owners don't really appreciate this. In the past comparisons to the BMW M5, they know the E55 is significantly inferior in the handling aspect. Their claim to "superiority" is strictly related to huge low end torque for mind-blowing acceleration.

Now, the E63 is more like the M5......naturally aspirated, torque is not as high, and you need to rev the engine a bit higher before you get the maximum power, better handling,, etc, etc.

People who have bought the E55 didn't buy if for its handling around a track. For them, the E55 is a comfortable street sedan which has mind-blowing acceleration on the streets. And for that, the E55 probably is the better car, compared to the E63 or M5.

Personally, I rather like the direction the E63 has taken. It's still wickedly fast in a straight line, but it's handling has been improved over the E55. Overall, it's a better performance car than the E55, IMO.

Hey Just_Me. Another piece of info from AMG about engine weights. 47lbs translates into 21kg. Since the 6.2L V8 weighs 199kg, we now can infer that the supercharged 5.4L V8 weighs (199 + 21) 220kg.

You should add this to your engine weights thread.
