So Lex, which one are you going to be purchasing? I look forward to seeing pic's of whichever SLR, SL65, you end up buying.....When are you going to be making this momentous purchase?

 

This thread is so lame.; which is faster the V8 or the V12 - do the math, the 12 has 30% more potential - end of fantasy story.

Regards, Jack

 

your try to say that the V12 is better because it has more cylinders than the V8?

 

I dont think that this thread is lame at all its a good comparision between to very amazing vehicles both have their advanatages and disadvantages...i just want to hear what the general concenus was on each vehicle and which they would prefer over the other.

 

I am surprised I'm even reading this discussion, much less responding to it, but let me add some facts to the thread:

First off, the SLR is 600 lbs lighter than the SL65. This more than makes up for its torque deficit vs the SL. The weight advantage shows up in the 0-60 and 1/4 mile performance figures.

Next, the SL600 is slower than the SL65. I've driven both, and *own* both an S600 and an SL65. Quoting magazine times from two different tests on two different days at two different locations is as pointless as... well, arguing on the internet Anyone still doubting the acceleration difference between an SL600 and an SL65 is invited to bring their SL600 and visit me in Northern California, where I will arrange a brief but convincing demonstration. It's primarily a matter of physics - both cars weigh roughly the same, but a stock SL600 makes 460 RWHP SAE while a stock SL65 makes 525 RWHP SAE. The difference isn't as great as the 109 BHP rated difference would suggest; I'd say the SL65 is about 75HP stronger.

Based on my experience drag racing my S600 when it was stock, I'd wager the stock SL600 will run the 1/4 in 12.3 @ 117 on pump gas, and perhaps 12.1 @ 119 on VP Racing 103 unleaded (turbo cars LOVE race gas). Has anyone on this board actually put their stock SL600 down the 'strip to get some hard data?

Racing my SL65 when it was stock, it ran 11.7 @ 123 on pump gas, and 11.8 @ 126 on race gas (wheelspin city in 1st gear). To put this in perspective, that means the SL65 would be 3-4 carlengths ahead of an SL600 at the end of the 1/4, and moving 6-7 MPH faster.

Finally, the SL65 is not a roadrace car. Roadrace cars are light, noisy, and have big brakes and tires relative to their weight. The SL65 is heavy, quiet, and has small tires and medium brakes relative to its weight and power. Those unclear on the difference should try braking downhill into turn 2 at Laguna Seca from 130 MPH.

The SL65 is a great GT car, and happens to be quite good at drag racing as well. I love it.

 

A breath of fresh air! W/real facts backed up by real personal experiences......I was wondering when someone was going to bring up the SLR weighing 600lb's less than the SL600, SL65

 

well if you chip a sl65 amg it jumps to 650 hp, passing all mb cars... would this difference make it better than slr?

 

I'll have hard data in a few more weeks, but AFAICT an ECU reflash for the SL65 will put it in the same power-to-weight range as the SLR. That still doesn't fix the weight or braking deficit, but it helps even the odds at a dragstrip.

Of course, one could put a pulley in the SLR... :v
