SL55/63/65/R230 AMG: 2005 SL65 AMG reserve your spot
of course one wouldnt be much more impressed by a 65 than a 55 at a track. these arent race cars. they are luxury GT's. they are about high speed cruising.
Too bad in the US we really can't go that fast on the highways.

Only use for a fast car is track, and well the SL/S/CL65s aren't track cars.

Edit: After the SL55 there's very little way to put more power and still be usable. The SL600 just smokes the entire time but still keeps similair times to the SL55.
The architecture of the SL is wrong to put more power down. For that, you need more weight over the driven wheels by using mid/rear engine (F360/911), putting the gearbox over them (trans-axle like the Porsche 928 or the new Ferrari Scaglietti) or else 4 wheel drive (Gallardo/Veyron).
True, the SLR uses the same architecture as the SL but the engine in the SLR is moved back to shift the weight balance and results in an absurdly small cabin for the size of car. Oh, and the critical reaction to the SLR has been far from ecstatic. How Mercedes think they are going to sell 500 of the things a year after the initial rush, I have no idea.
All of which makes the SL65 irrelevant in my book, especially in countries where top speed is not usable.
If the 65's are pointless, then even the 600's/55's are too. None of the 55K cars handle like 911's on the track, and neither is track performance relevant to any people who drive real cars on real roads. The 65 cars have too much power and since powerful cars need strengthened components, a further 200kgs has been added on top of the 600's weight. And like my earlier statement about the 55's handling, anyone who intends to track ANY of the 65 cars is an idiot. The 65 cars are too damn heavy, and sending 1000nm to similar wheels as those on the 55's is idiocy in itself.
And if people think the 65 cars are more faster than the 55's 0-60, no way pal. True 0-100mph to anyspeed, they will annihilate the 55's, but how often do you go autobahn kill hunting? To fully exploit the performance of the 65 cars, and their extra 30K GBP worth over the 55's., you first need wider rubber, and a 186mph limiter, then you will feel you have got your money's worth...
For whats its worth, IMO I think buying a 65 right now is pointless, they are not that much more faster than teh 55's to merit their extra price. Wait until this time next year, when you'll probably get your hands on a 700bhp version of these cars, hopefully with no extra weight, THEN you will feel a difference...
but with 1200Nm going to the same wheels, probably even at lower revs, you're not doing yourself any favours...
Bottom line: Sure the 65's are more faster than the 55's, but if the 55's have traction problems as everyone in snowy/rainy places knows, even with ESP on, thenw what the hell are you paying extra for? An extra 100bhp? wait til next year, we're going to get 700bhp, then they'll be worth their price...and trust me, the 65 engine is ALREADY capable of outputting 700bhp, just ask AMG
To put this into numbers, the SL600 has rated peak torque 14% higher than the SL55 (590/516) which is partly offset by a taller final drive (2.65/2.82) yielding 7% more thrust to the rear wheels, assuming proportional transmission losses and assuming the same weight and that third gear acceleration begins just around the peak of the torque curve, which is approximately correct. Add the 80 extra pound feet Treynor got from Renntech mods to his S600 and you have (670/516)(2.65/2.82) = 22% more thrust in third gear. An SL65 with 1000nm or 738 lb-ft would give you 34% more thrust. Is this power usable? Certainly: second gear in an SL55 gives you 55% more torque to the rear wheels than third gear. The car has no trouble handling second gear on a dry road in a straight line. Hence what the SL65 gives you is near second gear acceleration at third gear speeds, which sounds pretty desirable to me. Of course the Renntech SL600 gets you 1.22/1.34 = 91% of the way there so that seems to be the optimal value/performance point relative to the SL65.
The Best of Mercedes & AMG
Add another 200kgs to an SL600, and you'll see the performance advantage OVERALL isn't that much (55s vs. 65s).
IMO, wait for a 700bhp version...
the engines do overwhelm the cars. accordingly, the throttle has to be feathered in to avoid continual spin control.
compare two 65s with weight distribution and all else but weight being equal, and it's a good bet that (to a point) the heavier of the two will fare better off the line.
remove spin control, and both will smoke with relatively light throttle-in.
the best way to transmit all that torque to the pavement is via four wheels. properly engineered, handling should improve as well.
just my $.02.
Get ready for it; the SL65 4Matic!

Sadly, this may be the only way to get that, the SL600 and the SL55 off the line flooring it for the fastest times.
Edit: For the gentleman that said people buy the SL600 for what modification limit it has over the SL55, that is utterly false, only a small amount (yes all three of you guys) would do that
The consumer of these kind of cars doesn't know the difference between any of this crap. All they see is V8 vs V12, and that's almost (to them) nothing of a difference. Mercedes quotes both vehicles with the same horsepower (493) and that is the common view to what sells cars.

Most of the time here, speed limits are being reduced, not increased. There's a trend of imposing 50 limits where previously they were 60 and so on, all in the name of road safety. Soon, they'll figure out that if there's a blanket 0mph speed limit, no one will die on the roads...
The problem with the idea of a V12 4-matic is finding room for the front differential, plus the added weight.
HWA has tried to develop an S55 AMG 4Matic. They maxium the could use was a 380 hp engine. Everything stronger than that, ripped the ***** apart.
Anyone that has driven the SL55 on a big track would agree that more power is not needed but would still be used to bring lap times down if long straights are in the track.

2003 SL55 AMG
Anymore info available on the up-coming SL65 AMG...
Or, where can I find info about the SL65?
I'm #2 at my dealer {Delivery Oct - Dec 2004}
Will sell my 2004 SL55 AMG if anyone is interested....
All the best....

Sorry if it sounded as if I was serious!
