E55 vs M5 rolling runs: Torque vs Gearing
BMW M says: always make the chassis go faster than the engine. AMG should take notice.
However I heard from a friend who drove the S65 AMG that it is amazing acceleration. 4 people almost on par with the 800 HP Koenigsegg in a spontaneous race.
[I] Weight has an insignificant advantage in higher speeds. Aerodynamic advantage is alot mroe important where I beleive the SL55 has its advantages over the E55.

The E has the aerodynamic advantage.

Please, I just had to laugh. You are doing a stereotypical mistake it w<s along time ago Ive heard: mixing up the Kingdom of Sweden with the neutral country outside the European Union: Switzerland.
Glad I dont need to use any words againit anyone here you just prove in your own words your knowledge about history, georapghy, physics etc.
For the record.: Sweden does not produce quality watches en masse, have bank immunity and the capital is not Geneva. Sweden does however produce excellent world-class bearings, cell phone nets, Vodka etc.

[QUOTE What you are saying then is that freedom of speech/thought/press is a valuable commodity as long as it doesn't offend anyone. Is that not a contradiction? How can you have one without the other? Your very own statement about "positive" is confusing. You seem to value it by your participation in these discussions but yet you want to control it and impose your definition as you see it. You afterall are in on these threads defending your positions. That seems to be of great value to you or you would not continue. This is positive for all concerned. But yet you want to reserve that right in your arena and categorically state that this would not be permitted if you were in control. It would also seem that requests for information/clarification are squelched by you but on this board you yourself are asking for it and are receiving it.QUOTE]

As you can see it is 0.3 faster than the stocker to 60mph, & 0.6 seconds quicker to 100mph & 0.7 quicker to 112.5mph. Most of the damage against the stock car seems to be under 112mph. After that I think heat soak gets to it as the cooling is not designed for this type of power.
I've also seen it on an RS where the chipped car gets on higher boost through the 2nd & long 3rd gears & heat builds up with the higher boost. Then the heat build up causes the car to lose out in 4th gear. Anyway, a boosted car does its damage in the mid-range as at high rpm most aftermarket chips run back to stock boost.
I'm not sure about an E55 but on an RS6 which boosts 0.8-0.9, an MTM chip boosts 1.3-1.4bar from 3000-5500. After that the chip runs the boost back down to 0.9 to redline. No use trying to force boost on a car where the hardware limitation of small turbo's can't flow it at high rpm. I believe roots type SC's will be the same.
But in the mid-range the chipped car will make loads of power & torque more & pull a gap on the stocker. Now here's the M5's times from the same mag. I could use other mags like Auto Bild that got faster times, but I think its fair to use the same mag.

As you can see the M5 is significantly quicker than the stock E55. I know Improviz is going to come with his time to distance speeches, but there shouldn't be a huge disparity there. And any that there is should be in favour of the M5 as in theory it should be better from a stop.
NOW, against the pulley'd 55, the M5 runs pretty even to 100mph, & 112.5. But after that it seems the heat soak issue & M5's high rpm power take over.
Hope to have a civilised discussion on this.

That's why these magazine tests mean little to us. That's why we continue to wait for the car to hit our strips. For that matter, these magazine tests should mean little to you. If Gustav's M5 with three passengers and a driver can run to 100 mph 6/10ths faster than Auto Bild and its much lighter car, then what is the value of the magazine?

If you want to do the physics calculations, you can determine the relative distance of each car to the other pretty accurately. According to this data, the E55 and M5 are neck and neck at 120 kph, or 5.9 seconds. At that point, the M5 pulls away at a steadily increasing rate to a 6-7 carlength lead by 200 kph.
Surely an M5 would also go faster on 2 gallons of fuel, no passenger, lowered rear tyre pressures & fronts overinflated, icing the manifold, race fuel, sticky surface prepped with VHT, roll-out, etc? Isn't it wiser to rather compare the M5 to the E55 Sport Auto tested using the same techniques? Dunno' maybe I'm seeing it wrong but I like to compare cars tested using the same techique & same timing equipment.

If the comparison was of two cars on the same day at the same facility using the same procedures, then it serves a COMPARATIVE value - even if the numbers are generally slower or faster in the "real world". The tests you cite are not same day tests. I don't know if they were at the same facility, what DA, etc. That is why it is of limited value, even if conducted by the same magazine. It suggests something, but it doesn't prove anything. There are probably magazines that have tested the M5 and it has proven slower than the E55. I discount those as well. I just don't like treating magazine tests as gospel. And I would say the same thing about the separate tests even if more magazines tested the E55 to be quicker than the M5's they tested. My distaste for magazine tests doesn't change based on the result.
All of this will be finally settled (hopefully) in the fall. Or sooner if someone in Europe can find a drag strip and post time slips. When the M5 gets here, I am sure that people will take it to the strip to see what it can do. Then this will be put to rest. And if it is faster and quicker, then great. It just gives AMG something else to shoot for. Remember, without the E55, the M5 would not be the car that it is, and vice versa.
For the record, I race with the same pump fuel that gets me to work. I don't touch the front tire pressure. I've found that icing the intake is of limited value, and hot-lapping showed a small decrease in mph, maybe .5 mph. Plus, two gallons of gas is way too little. You need at least a 1/4 tank to get weight over the tires. In fact, I actually did better with a 1/2 tank than I did when the reserve fuel light came on. Go figure.
With all this talk about E55 comparison to the M5 may all be moot with the new CLS65 (V12TT = 600+hp) coming out. What's your thoughts on the CLS65 compared to the new M5.
Will they use the same engine as in the SL65 ?
The SL65 did not manage to take use of the extra power over the SL55 on the ring, not that it matter for you US guys probably.
The SL55 was actually a tiny bit faster, that shows that to improve on a fast car takes more than just extra HP, when you also add weight as in the case of the SL65.
But it is an amazing car that I would love to try out.
BTW on a long long upwards streetch on the Ring the SL65 hit 167 mph, funny enough exactly the same speed as the M5 on the same spot. Exit speed on the turn leading to the straight was on the SL65 77 mph and on the M5 81 mph so the SL65 did manage to increase the speed more than the M5. ( on a side note the M5 had then been bouncing on its speedlimiter for a few seconds...)
The SL65 did the ring in 8 min 14, 2 sec slower than the SL55 and and 1 sec slower than the M5. Prette even steven if you ask me and extremly fast.

As to aerodynamics, you're totally wrong (which seems to be a trend); the E55 has a superior drag coefficent to the SL55.
From Mercedes: E55 Cd: 0.27
From Mercedes: SL55 Cd: 0.30
Nice try, but totally wrong.
I.e., as I said: you are a first class hypocrite. Thank you for admitting it.

I will make this easy for you. Can you please point me to one comparison test, anywhere, where two cars tested 0.8 apart from 0-125 mph were tested more than a tenth or two apart in a 1/4 mile race, if even that? We already saw that in two previous examples I cited, cars which were two full seconds apart at this speed ran in one case identical and in a second case 0.2 apart 1/4 mile times.
Here are more. Car & Driver, August 1999. Camaro SS, Pontiac Trans Am, Mustang GT.
1/4 mile time:
Camaro SS: 13.9@103
Pontiac Trans Am: 13.9@103
Mustang GT: 14.6@98
0-130 mph time:
Camaro SS: 24.6
Pontiac Trans Am: 22.8
Mustang GT: 31.8
Facts: SS ran 1.8 seconds slower to 130 than Trans Am, but the two tied in 1/4 in time and trap speed. Mustang was 7.2 seconds slower to 130 than SS, and 9 seconds slower to 130 than Trans Am, but was exactly 0.7 slower to 1/4 mile than both. The M5 and E55 are 0.8 seconds apart at 125.
Car & Driver, October 1999 BMW M roadster vs. Honda S2000.
1/4 mile time:
S2000: 14.4@98
Boxster: 15.0@93
0-130 time:
S2000: 24.1
Boxster: 28.2
Fact: cars were four full seconds apart at 130, but only 0.6 apart at 1/4 mile. The M5 and E55 are 0.8 seconds apart at 125.
December 1999. Mitsu Eclipse GT vs Toyo Celica GT-S
1/4 mile time:
Eclipse GT: 15.4@91
Celica GT-S: 15.7@90
0-120 time:
Eclipse GT: 30.7
Celica GT-S: 35.7
Fact: cars were five full seconds apart at 130, but only 0.3 apart at 1/4 mile. The M5 and E55 are 0.8 seconds apart at 125.
September 1999: Mercedes C43 vs BMW M3
1/4 mile time:
C43: 14.6@99
M3: 14.6@95
0-130 time:
C43: 29.2
M3: 33.2
Fact: M3 was four full seconds slower to 130 than C43, but tied it in 1/4 mile. The M5 and E55 are 0.8 seconds apart at 125.
FACT: M3 AND E55 ARE 0.8 SECONDS APART AT 125. THIS IS FAR CLOSER THAN THE EXAMPLES CITED IN THIS POST. ERGO, TO STATE THAT THE M5 WILL BE NOTABLY FASTER IN 1/4 MILE IF AT ALL IS WISHFUL THINKING.

Show one example where two cars 0.8 apart at 125 were tested appreciably different in a 1/4 mile race. Put up or shut up.

We were talking about 0-125mph, which none of these cars do over the 1/4. After you cross the line the gap will widen to 0.8 at 125 & the keep getting wider. But on the 1/4 it will be close.

Care to hazard a guess on what its trap speed will be as well, oh great prognosticator?
Oh, and you ignored my earlier request, so here it is again (Gustav and/or Erik, please feel free to do the same): would you care to cite one example from anywhere where two RWD cars tested at 0.8 apart at 125 mph were 0.3-0.4 apart at the 1/4 mile? Just one would be great...really. Got one?
I'm waiting....

Improviz i don't think people are claiming that since the m5 is quicker to 200kph by 0.5-1sec that the same will eventuate in the 1/4. Incase people don't understand the difference between time to distance and time to speed bare in mind that it is possible for a car can be slower from 0-100kph but be infront of a car that records a faster 0-100 time.
I've done some quick SS calcs using numbers from a few euro mag sources and those numbers show the m5 at about 12.4-12.6 at approx 117-118mph. So the m5 will at worst hang with the 55's in the 1/4.
Improviz do you agree that the M5 can be faster both from a dead stop and roll, unless everyone here agrees that it can be then there is not much point argueing what the margin will be.
SL55 E55
0-100km/h 4.90sec 4.81sec
0-400m (1/4mi) 12.90 @111.7mph 12.94@111.9mph
0-1km 23.32 @142.3mph 23.26@ 144.6mph
not much difference between the two
