Driving impressions: E55 vs. SL55
In the SL55, even at low speeds you hear the engine growl, and feel a rumble in the seat of your pants. Step lightly on the gas, and the tires bite into the road and zip you forward. In the E55, keep light on the gas and you'll think you're driving an E500. There really is no intense feeling of power, and the car doesn't beg you to push it harder.
I suspect part of this is due to the 2.65 differential in the E55 vs. the 2.85 in the SL55. The rest may be due to ECU tuning and/or supercharger control. It seems the supercharger in the E doesn't stay engaged unless you have been driving very aggressively, and it is unpredictable in delivering its full potential. The SL has a lower threshold to go into super pursuit mode and seems consistently ready to play.
Has anyone done ECU mods or differential swaps that give the E55 a more intense feel? I wonder if swapping with an SL55 ECU is possible?

Thanks.
The W211 had less than 20 miles on the clock so it may not be reprsentitive of a fully broke in engine. Nevertheless, from a 20mph roll the SL pulled a good car length up to about 70 when she slowed down.
My seat of the pants dyno says the SL pulls harder from the get go, which I believe is due to the axel ratios. I find that the E-55 can easily spin the 265 tires which would be another reason for the higher gearing. I'll do some Gtech timing to confirm times if it doesn't rain this weekend.
I would say the E55 is faster by a bit.
I will be taking my SL55 to the drag stip next month to see where it ends up.
The SL55 sounds so much better than the E55 but I would have to say the the E is faster.

Have any of you compared the E55 and SL55 behind the wheel? I know everyone claims that the 469hp vs. 493hp is just marketing hype, but the SL55 really does drive like the more aggressive car.

I agree with the other posts that the E55 feels a smidge faster than the SL55. The exhaust roar from the SL55 make it sound faster, but I find this a little over the top.
I debadged both vehicles and prefer the element of surprise, which is tougher to pull off with the noises that come out of the SL55.
Also, I feel the handling of the E55 is a little better than the SL55 because of the 400 fewer pounds it lugs around.
The ultimate sleeper is the SL600 in non-AMG trim...

Man, that's the biggest understatement of the year! I saw the recent review by Car and Driver and just about fell out of my reading chair. They reported the SL600's ability to hussle it's not so svelte 4501 lb frame to a 0-60 in 3.6 seconds and the 1/4 mile in 11.9 @120 mph!
Here is what they said about the comparison between the SL55 AMG and the SL600:
"Yet another contrast: The SL600 trumps the SL55 AMG, even though the AMG edition weighs in a tad lighter (4410 pounds) packs the same horsepower (493), and is the designated SL family hot rod. But in our Novemnber '02 test, the SL55 managed only-only!-4.5 seconds to 60, and cruised through the quarter in 13.0 seconds at 110 mph."
Sorry ... didn't get pics ... here are stock photos (unfortunately not with the very cool wheels that I saw):

The night I picked up my E-55 from the dealer my wife was driving the SL-55 following me home. I couldn't resist the temptation to see how the E-55 would do.

0-80 6.30 6.30
1/8 mile 8.18 8.12.
The ESP was far more intrussive on the SL than the E at launch I believe in part due to the lower axel ratio. The Sl has 9100 mi. and the W 211 has 1100. E-55 was easier to launch and get traction than the SL. Next test will be to go head to head. Stay tuned for more fair and balanced reporting.
