Tested E63 & M5, Run with E63 vs E55
The fact is, that I am happy with my E55 and will probably not get an E63 because my E55 fulfills my priorities better than an E63 would. I'm not saying the E55 is better than E63, or vice-versa. In fact, I think the 63 engine is a great engine and the cars it is installed in are equally nice cars.
However, the power delivery the new 63 engines provide is not what I am looking for in this type of car. I love fat lazy torque and they simply don't have enough of it for me. It's not a case of which car is better. It just happens to be that the E55 is the better choice for me. But hey, if it makes you feel better to judge me because I am not "jumping to the E63", go right ahead...
will be posting pix soon!!!
Thanks for confirming that my informal results were not crazy, that my E55 was not slow from improper flashing, that my buddy knew how to drive, etc, etc, etc.
I was going to say that, but you beat me to it.

Every car is different. This could have been a very quick 63 and a slow 55. I've seen too many dyno's on this board where a 55 was reflashed with serious loss of power. I've also seen where the 55 is slow when its been driven slow for a while and needs readapting. The intercooler pump on the 55 may not have been working at optimum.
Too many variable, but I think this is a piece of evidence that supports the 63 being faster for most speeds, but I would like to see more. Time will tell.
The Best of Mercedes & AMG




They were evenish - but SL55 seemed to be marginally quicker.
When I drove my 55 the following day it felt sort of faster and slower - so I dunno - until I run against my friends SL55 I wont know.
Happy you found the car you like ... !!!
As I said there the 63 motor is lurvly - but the box to me was not gr8 - it could be so much better with tighter 4567 gears.

Since your seem so doubtful, why don't YOU go out and do a comparison and write it up for us.

The box seems quicker than the 55's, could be in my mind though as the car revs like a bike. You're right about the gearing, they should have shortened 4th onwards but spacing upto 200kmh seems good, better than the 55 and after that into 5th the motor really does its work well, unlike the 55. I will prefer a fifth that goes to 265kmh.
I run 95oct unleaded and we ran sea level, literally right next to beach. Being a normal aspirated and supercharged both were at there best. Not sure if i mentioned the 63 had 4900km on it.
Picking up an M5 on Monday and going to video that too.








You must get allot of - "I dont believe it !!!" from guys in ferraris etc when you leave 'em standing ...
How do u get the power down and how much rwhp have u got ?
Whats its best 1/4m time?
2 stage 300hp nos
ford v8 9inch diff lsd
11.2 sec turbo only @ 220km/h on street tyres.
I would like to see some more 1/4 mile times and trap speeds from the 63. If the car is faster it should trap at similar or faster speeds. I think the jury is still out. I love Mercedes and would have no qualms about buying a 63 when the time comes.
Its not that big of a deal to me and I believe overall that the 63 is a better package than the 55.
