Just traded my 2019 C63 Cabrio for a 2017 SL 63.
Having trouble finding any good magazine tests with performance numbers in them.. just very subjective stuff.
anyone point me to a good test from history that shows actual 0-60 mph and 1/4 mile speed and time?
Car feels stronger ( way more torque) but not faster than the C63 so far.
Anyone tracked a totally stock car?
thanks,

 

There were no performance changes for 2017 from the 2015 version, correct?

The 2015 tested slower than the 2013 despite no real reason for it doing so. Some speculated that MB detuned the SL63 a bit to allow the SL65 to be faster, since the 2013 SL63 was faster than the 2013 SL65.

Stock to stock, it's probably only slightly faster than a 2019 C63.

 

I recall that road test. I question a totally stock 530hp SL63 doing a 124 trap speed. The 2015 test numbers look more realistic. In 2018 I drove all the AMG's (no V12's) at Laguna Seca in the AMG performance driving academy. Because my driving partner did not want to drive I was able to do 10 laps in each car. His judgement was questionable that he trusted me more than himself. Laguna Seca has a lot of elevation changes and short straights, it is not a high speed track. The AMG Academy is run by professional race drivers who do this in between competitions.
When it was time to drive the SL63 the instructors said "this car is the real sleeper of the group. It is the most comfortable and second fastest around the track". Caveat, the E63S was only used for infield competitions, not for track lapping. The C63 was a 2 door coupe, it was good but definitely did not pull as hard as the SL63. The GTS felt a bit faster to me around the track but it did not seem to pull harder than the SL63. The GTR was another matter entirely, it was faster in every way on the track. Downside, at least for me is I would never want a GTR as a daily driver.
FYI, all the track cars wore Michelins, all the infield cars wore Conti 5P's. I also noticed when the cars are prepped they use track specific tire pressures. The SL was set up the same as I do for mine, 4psi higher in the fronts to help neutralize the handling and drifting.
I have no idea if AMG did something between 2013 and 2018 to the 577hp SL. Hopefully they improved the transmission clutch pack operation. We had a 2014 E63S with that engine/transmission and it was horrible. The 2018 with the 4.0 and 9 speed we now have is way better and much faster. The 2018 SL63 used on the track seemed ok as regards the transmission shifting. I own a 2017 SL65, as a daily driver the V12 is the better car in my opinion, much more torque, smoother and the torque converter is more enjoyable to drive on the streets. The problem with it is off the line traction and hookup. The SL63 would likely beat it to 60 but not through a quarter mile.
My takeaway, without actual acceleration numbers is the SL63 is a fantastic and well balanced performance luxury car. Hope this helps somewhat.

 

Very helpful.
thanks

 

It was the 557hp performance-package 2013 SL63 that they said had a 124mph trap. It's certainly possible that MB gave them a bit of a ringer with extra boost.

C&D of course had the infamous SL600 test (400 lbs heavier, rated at 493hp) which ran an 11.9@120.

 

I had a 2005 SL600 rated at 493 HP. Advantage was it hooked up really good. 11.9@120 stock? No way. It weighed 4400lb. After the Eurocharged tune it was much faster. Maybe a 120 trap after the tune. I still have a 2009 SL600, I think that year is rated at 514hp, it is not going to trap at 120 w/o a tune. Again, with the 5.5L and 600 ft-lb they are much easier to launch than the AMG version. Sitting in the garage next to it is a 2017 SL65 These two V12's a so far apart in performance it is hard to describe. The 2017 is supposedly 150lb lighter than the 2009. I am sure that with a competent driver on a sticky track it would trap in the high 120's. We used to have a 2014 E63S with the 5.5/7speed combo. It weighed 200lb more than the SL600. It was not faster than the SL600 after about 30mph when the AWD advantage was gone, so it was probably just under 120 in the 1/4 mile.. Our 2018 E63S pulls much harder than the 2014.

 

My 2013 SL63 with performance pack, totally stock right down to the air filters and Michelin pilot super sport tires:

0 - 60 with 1 foot rollout = 3.50
0 - 60 no rollout = 3.71
1/8 mile 7.67 @ 96.31 (on terrible 1.98 60' launch)
1/4 mile 11.69 @ 122.68 (on terrible 1.98 60' launch)

 

impressive numbers!
Is the 2013 with performance pack also 570hp and 660 lb ft of torque?
Thanks.

 

In 2013, in the USA, the factory rating was 557hp / 665 lbs ft (900N)
The service advisor at my dealership says it’s very underrated.

 

the 2013 must be underrated,, anybody have a dyno around to test it....?

 

My 2013 SL63 stock dynoed at 530whp, 569wtq at Eurocharged, STD correction factor. SAE correction factor would be about 518whp.

My car does not have the performance package.

Anyone dyno a 2017? Or a pp 2013?

 

you can always have the, any, 5.5 re mapped with a renntech ecu and get 669 hp, 734 tq for about $3k

 

hmmmm renntech , closest for me I think is st louis....do they remap and dyno?

 

the new one is a hand held that you plug in. self serve

 

does that have to be 91 octane 93 or 100 , pump gas, ???

 

They will probably set it to whatever you request. The baseline seems likely to be a 93 octane tune. Eurocharged has similar tunes available that you can add yourself via an OBDII device (MyGenius).

The below, which is the basis of their 669 crank hp tune, only shows 575whp - which is definitely on the very low end of SL63 tunes. Maybe it's safer? They also only show a stock SL63 at 484whp, whereas mine measured 35-45 whp higher depending on the correction factor they used. It's advantageous to show a low baseline result of course.

???

 

DIN is slightly more favorable than even STD , are you in Europe? Places that show different scales for HP vs TQ always kind of irritate me.

After a slight adjustment for correction factors your car dynoed what it should vs. mine stock ... about +20 peak whp, +75 peak tq. That's within reason for the rated numbers of a 2015 (engine 577/664) vs. a 2013 non-PP (engine 530/590). So I'm not sure why the 2015 tested so much worse than the 2013.

Is the tune from MSL performance also, or did they just dyno? It didn't seem to add much (~20whp), although at least it's constant throughout.

 

I need some help understanding these graphs. The formula defining the relationship between torque and horsepower is HP equals torque times RPM divided by 5252. Mathematically torque equals HP at 5252rpm, so that is where the curves always cross. On the posted graphs they cross at 4500rpm.

 

There are different scales for HP & TQ.

 

Thanks, that explains it. I must be really slow today.

 

???

 

hmm you are right the graphs have been monkeyed with, always torque and hp should cross at 5250 , I think this is not rwhp but calculated and regraphed…..even the alleged rwhp of stock was over 550 hp , not....even though I would love to think that was true!!

 

The curves do cross at 5252rpm, just need to put the y axis on the same scale for TQ and HP. I missed that when I first looked at the graphs. There is a lot of area between the stock and tuned torque curves in the RPM range the engine uses in normal street driving. The car will now feel much more powerful.

 

I run with my dragy 3.6 0-60 time is my best with my 2018 SL63... I have taken it to the drag strip twice.. I ran it 3 times my first time out, and never ran over a 12 second quarter mile.. 11.94 was my worst, my best the 2nd time I was out I ran a 11.47 at 126.6 mph. The car is serious fast, and I have raced a guy in a 2017 Nissan GTR, (on the highway with no cars around), and off the line he is quicker, but I pull on him at higher speeds and can pass him... but by then we are well over 130 mph.... I have never lost a higway pull against another car.. ever. But then there are faster cars just more rare I expect.. I also out pulled a E63S wagon, I guess 2018 or 2019 model year.. I was faster from 60 mph to our final speed (he let off because I was ahead and getting further ahead)..
