SL55/63/65/R230 AMG: Is SL63 a bad buy?



Ted



As far as engines go, the 6.2 is a terrific engine. It makes as much horsepower as the 55K engine but without supercharging. It doesn't have as much low end torque, though, so it's not quite as quick off the line. From a roll, though, an SL63 is going to be about as fast as an SL55.
All-in-all I think the SL55 is a marginally better car but if a friend was thinking seriously of buying an SL63, I wouldn't try to talk him/her out of it.

MB had to change the front of the SL to bring it into compliance with the EU pedestrian safety standards. If they hadn't addressed this, the company would not have been able to sell the SL in Europe going forward.
We are all just speculating when the new SL (R231?) will be introduced, but most people here think it will be in 3-4 years. It is hard to imagine that it will be any longer than that given the rest of the design changes that have taken place throughout the lineup.
Basing a 130k purchase on a fantasy 0-62 test result is folley.
There is information that contradicts your post from many sources, this includes AMG the folks that BUILD the car and test it extensively prior to bringing it to market

The SL 63 AMG accelerates from 0 to 100 km/h in 4.6 seconds before quickly going on to a top speed of 250 km/h (electronically limited).
AMG supercharged 5.5 L (5439 cc) 24-valve V8 engine 497 hp (367 kW) at 6,100 rpm, 0 to 100 km/h (62 mph) 4.7 s
I show a 0-62 in 4.6 s from the horses mouth vs a 4.7s for the SL55.
The SL 63 is a HUGE improvement performance wise even over the 2007 63 models. MCT and the ability to choose 4 performance styles, plus TURNING OFF ESP completely w/o dyno mode is a plus. Ability to blip throttle, new telematics, better seats, brakes, , faster shifting 20%, man wish my car had all that the SL offers :-)
Looks wise I think the model it replaces looks better, but the performance enhancements are worth quite a bit.
This sounds like an AMAZING improvement IMO
THIS IS LC in A BENZ WOOOOOOOOOOOOHOOOOOOOOOOOOO

IIRC, CY02 SL55 scored 8:06 NBR (?SportAuto test)....
MY07-08 SL55 has ?30 more hp/lb-ft; ABC 2.0; sharper steering....presumably latest street tire tech/perf/grip is increased vs 5yrs prior....
Will be interesting to see what NBR time SL63 030 scores on street tires and in which MCT mode best time will be achieved...i.e., S+ vs Manual....

Am getting SL63 030 (Apr build)....having owned various new SL55/65 over past 5yrs, am really looking forward to this MCT box and the greater AMG focus on chassis precision....and the brilliant, linear 63 motor, which is ?75lbs lighter over nose than 55 motor.....

But you will get all this + much more AND a new chassis, by waiting 2 yrs. I say 2 yrs because the sl63 will be a 2009 and by 2011 there has to be a new SL I would think. +the SL is a heavy car in need of tourque as much as HP.
BUt I suppose that in the first year the SL's will be hard to come by and tough to get and the AMG models will probably not come out right away. blah blah blah...so maybe....but if I had a sl65 or 55or 600 I would not trade it for the 63.

Oh WOW!!!
Thanks for the info.
does it also have Launch Control?
Man the 2008 SL55 is a monster. These guys are jokers with the HP ratings.
from 469-510 same engine LOL..

You know, if you don't like other people making polite corrections to your posts there's an easy solution: don't post incorrect facts in the first place.

Re: your second post, as you know there is no launch control on the SL55. Yet despite its inferior engine, inferior transmission, and lack of launch control the 2008 SL55 launches faster than the 2009 SL63. Go figure.
While MB does appear to play games with the horsepower numbers that's not the case with the late model SL55s versus the early model SL55s. The later model SL55s have an 80 mm throttle body and genuinely do produce more horsepower. Hence the decreased 0-62 time for the later model SL55s.

Thats great the SL55 has some features that make it faster in a straight line but it is unlikely the SL 55 08 would keep up on the ring with this new 63.
As far as the 0-62 times looks like a .1 difference not the .2 the OP claimed.
In my mind many of the new features of the 63 are well worth the price of the car. Wonder if the C63 has this Launch control feature?
AMG has the 63 rated at 4.6s so there is a .1 difference 0-62mph not significant, while a few seconds on the ring will be.
