Hi, I have just driven a SL65, but preferred my SL55, more exhaust rumble
and more nimble. I am now thinking of the SL63, I have heard they make
a nice noise and look good. However on the downside several members
had indicated that the SL55 is faster, and I believe the 63 can't be tuned.
Any comments would be appreciated.

I've not driven an SL63 so I don't have personal experience but reported times for stock SL63s are in the same neighborhood as stock SL55s, e.g. http://www.caranddriver.com/reviews/hot_lists/high_performance/mercedes_benz_amg_performance/2009_mercedes_benz_sl63_amg_road_test/(page)/1

I have heard the SL63 on the road and can confirm the exhaust sound is heavenly.

ECU tunes and other tuning products are becoming available for the 6.2L engines, e.g. this Renntech-tuned C63 was able to run 1/4 mile in 11.57 seconds trapping at 120.91mph: https://mbworld.org/forums/c63-amg-w...le-record.html

Both loved the SL63 both said it handles better, sounds better.

Both liked the SL55 more. It was the engine!!!!

I own a SL55 and we have tuned a number of SL63s, so I have had some seat time, both in our client's car as well as when we were developing the tuning.

The 63 is a step forward.... in the overall car, and especially the gearbox. It is brilliant. Engine wise, I still think the 55 is the ticket. I love the power delivery and the torque. I think the 55 has more character. The 63 is great, with a sound to die for, but I still have a 55 in my garage.... for whatever that is worth!

Thanks guys, looks like the only way to find out is to drive one.
I hope it does not drive like the SL65 I drove. Can anyone give me an idea
how much extra bhp you can get from a 63, and will it improve the torque.

if you are willing to pay, carlsson has a performance kit that bumps power from 525ps to 600ps and torque up from 630nm to 705nm...

i can understand how you guys like the low end torque of the 55k engine more, but this 6.2L is just way more free revving and the mct does transform the car! the combination of these 2 components and the better handling makes this a car that is closer to a true sports car. if you enjoy that then i think you will like the SL63 more. but if the only thing you are looking for is the monster torque then this wont be your car (not that it lacks the torque, i mean a 6.2L has tonnes of torque, but when you are already used to the 55k's monstrous torque then its a different story...)

to be honest i wasn't much of a fan of amg's until the c63 and sl63 came out with their respective gearboxes. i have driven older amgs and i can only perceive them as a much more powerful merc. the gearboxes were really disappointing. but with the new ones now, they just get better and better!

and yes you are right. i think the thing to do when deciding if you want a car or not is to test drive it yourself. i got a real good surprise when i test drove the c63 and e90m3. i drive an e46m3 in toronto and i guess i was biased to the m cars so i thought i would like the e90m3 more. after i test drove both, yes i agree that the handling is a bit better with the m3 but i just like the c63 so much more! now go test drive one and see for youself!

hope this helps!

just drive an SL63, you will love it. Its worth it just to hear the engine.
I cant get enough of mine. It was 75 and sunny today for the first time since I bought it and my 10 minute drive home lasted an hour.

lee7758

I totally agree with that! Once you drive the SL 63, you will love that. Especially the tranny ( MCT tranny )!!!!!

I don't know, if you didn't like the power of the SL65, how are you going to be happy with a SL63?

Thanks guys for the input, I would love the Carlsson kit but it's mega expensive.
To answer AMG Dictator, it's not a question of power. The SL65 felt smooth and quiet, and very unlike a sports car, more of a cruiser, my SL55 by
comparison felt nimble with a great exhaust note, far more like a sports car.
Driving the SL65 would be like driving my CL65 so I can't see the point.
However I get the Idea that the SL63 is even more raw than my 55, it has
aggressive looks and a great sound track according to other members.
I will find out, I have booked a test drive, just waiting for my dealer to get the car, then I will post my thoughts.

if you are looking for a sporty feeling, then definitely the SL63 will be better than the SL55.
power upgrades it goes to the 55K though.

If you go 63, just paint the side vents.
