Not personal.
Just feels like there are too many here spouting disinformation or with axes to grind because Mercedes isn't doing exactly what they want.
Seems like every time there is a new model the get off my lawn crowd starts wailing.
People haven't even seen the car or driven the car yet.

To me the in line 6 is a much more authentic offering for the SL than the V6. The 4 banger not at all.
How do you figure? All of the video 'reviews' in that garage/studio with both the SL55 and SL63 have been by European journalists.
I agree that a 4-cylinder will not fly here. It will be a tough sell in even the C-class AMG.
New SL are always launched in the US. Historically the US market has been the largest market for that car...
Doesn't matter where YouTubers and other journalists are located. The one thing to remember is that Mercedes has ceased ICE engine development and we are living off existing tech and emissions control will be the driver of what engines go into cars.
So if people won't like a C63 with a 4 banger (which I doubt as long as it's faster and sounds ok), too bad so sad. Time to look for another brand.
I agree that the engine line-up hasn't been confirmed officially and much can change due to availability (Mercedes has up to 2 years lead-time for several models in Europe and around the world), chatter from Mercedes indicated that the SL55 was to be a US only model.

The SL launch was global. No mention of the SL55 being exclusive to the US. It is on the Mercedes UK website. Whatever 'chatter' you heard was incorrect.

I guess we'll see. So far, any pre-production cars listed on websites typically means nothing unless somebody in the UK can actually order one. The car is officially available for purchase in Europe in March 22.
And yes, I should have corrected myself. The launch for the SL was planned to be in the US a month earlier but then stopped at the last minute.
I agree. The six cylinder M256 mild hybrid engine with the 48 volt MGU is incredible. I love the combined 560 ft lb of torque and 450 horsepower in my CLS53 and I'm looking forward to the same engine in my 2022 GLE53 that is on the way to my dealer. This engine would be an excellent choice for the entry level SL.
The CLS53 does not have 560lb-ft of torque or 450hp lol.

Hmm. I don't know about your CLS53, but most, like mine do when adding the 21hp and 184 lb-ft of torque from the MGU/ISG to the 429hp and 384 lb-ft of torque from the ICE. Same for all "53" series models which also include the 48-volt mini-supercharger which is not included in the "450" models. If the 4-passenger CLS53 can do a 0-60 run in 4 seconds, an SL53 should be capable of well under 4 seconds. Oh wait, the new SL is pretty heavy. You can brush up on the M256 engine here:
Every Mercedes-AMG CLS53 comes with a turbocharged and electrically supercharged 3.0-liter inline-six-cylinder engine with a 48-volt hybrid-assist system called EQ Boost, a nine-speed automatic transmission, and all-wheel drive. The engine is rated at 429 horsepower and 384 lb-ft of torque, with EQ Boost adding up to 21 horsepower and 184 lb-ft. The CLS53 we tested hit 60 mph in 4.0 seconds and covered the quarter-mile in 12.5 seconds at 111 mph.

It's not total system power. The quotes you're using are telling you what the hp and tq numbers are. The EQ Boost system is used to fill in the gaps to eliminate turbo lag, it does not contribute to total engine or system power. NO WHERE are these numbers combined for total system power. It's an assistance system to eliminate lag and reduce emissions, not and overall power figure booster. This has been explained profusely when the system was introduced.
You didn't read far enough:
The payoff for this technology is an output of 429 horsepower at 6100 rpm and 384 lb-ft of torque at 1800 revs in the version of the engine used in the AMG 53 models. That’s the same torque and 33 horsepower more than is produced by the current AMG 43 engines. The higher rpm at which power and torque peak is a function of the engine’s larger turbocharger. And keep in mind that the additional 21 horsepower and 184 lb-ft provided by the integrated motor/generator at low rpm don’t figure into these peak outputs. This is accompanied by a fuel-economy improvement of roughly 15 percent over the previous V-6 powertrain, although EPA figures are not yet available. Non-AMG Mercedes-Benz models will employ a lower-output version of the M256, without the electric supercharger but with the motor/generator and 48-volt systems. It’s rated at 362 horsepower as installed in the CLS450.

OK agreed. But the torque from the MGU is there when one needs it both at launch from the start and when say, downshifting and passing a vehicle. Come on man, get on board and drink the KoolAid. Even a fanatic like yourself can appreciate the magic of "53 ". It is a great package and that's why I ordered a 2022 GLE53 with delivery next week. This engine would be excellent in the "low-end" SL. The MGU is a pretty hefty motor and is just what a 3-liter engine needs.

I don't have anything against the package and all that is irrelevant, my point is that the HP/TQ numbers you stated are false. Nothing else.

Yes, but if one looks at just the ICE specs of 384lb-ft of torque, that is even more misleading -- the boost from the MGU provides a lot more than that. As you know, at launch from a start, at low rpm, the "spec" HP/TQ is not available from any ICE until maybe 3K rpm, just as with any turbo V8 or V6 at low rpm, even the revered 63S engines.That's why any 3 Liter engine (and certainly a 4 cylinder 2 liter engine) needs the boost from a MGU like that is incorporated into the M256 engine. I think we can agree that the mild-hybrid M256 engine does provide an exceptional level of performance and efficiency,( I drove from Denver to Sanat Fe NM at 75-80mph and got 34mpg in my CLS53 and it yields 4 seconds 0-60.) I think that should be the engine choice for the "entry-level" R232 SL. But alas, probably not....

Just amazes me how some are so concerned about the odd second and compare that to the price they are being charged. Unless you spend your time on the autobahn, who cares, or perhaps your testosterone levels need to be examined. In the US and many other places, I hate to think what the cops would do to you if caught going from the traffic lights say at under 3 seconds from 0-60. In what normally is a 20-40 mph speed limit. Vrrrrroooom vroooom. Feel better? Close you eyes and visualize the roar and not worry about spending 120-150K and not being able to(on paper) shat your pants. Yes, to each their own.
Anyway, I wasn't sure at first but coming round to ordering the 55. I don't need or want(bragging rights) the extra speed, HP, mine bigger than yours scenario. imho of course.....
We all can drive Corolla or model 3 and those vehicles will do the job to get us from point A to point B.
But, we have extra money and appetite for luxury features and performance and we buy those things to get satisfaction. Same as houses or any other material 'things'.
I'm in the category to have 3.0 sec 0-60 because I wanted that and it costs certain amount on the market.
SL63 so far as I know will not deliver that performance but dictate premium price and I do not agree with that.

I agree 1000%.... what is the big deal with a couple of tenths of a second. When I dealt with boats, I told people that nobody could tell the difference in one that would go 80 and one that would go 78. The only way to tell would be the GPS the graph has. People would pay fifteen thousand more for two miles per hour. You could take the stickers off the motor and they would never know...AND --Then a good driver of the slower boat would outrun them...LOL.
Most owners of the more expensive car that is a couple of tenths faster will never know it.....but they get hooked into paying for it.....and if they did take it to a track a good driver would beat them like a borrowed mule.
Most posters here seem to miss the point the OP made.
Unless underrated, the SL times are slower than equivalent V8 63 AWD Models. If the hardware is the same if should be quicker but MB chose to deliberately down tune the engine.
This is a valid observation.
Wether you guys think it’s quick enough is not really relevant. Just like colors, options or hard top vs soft top, different people have different priorities and performance is part of it.
So 3.5 seconds 0 to 60 qualifies as slow? if its about 0 to 60 / $ then buy a C8.
I don't get the need for something even quicker unless you plan on tracking the car.
If slower than the E63s or GT63s then the question is valid.
There is no SL63s, never was and the old SL63 was equivalent to the W212 E63s (same engine and power)
Once again, wether you think it’s quick enough isn’t the question.
If people wanted a quicker convertible for more money, why question the rationale?
I don’t question people spending $10k on solarbeam yellow paint. Even if it feels frivolous to some it’s their money.

The CLS53 does not have 560lb-ft of torque or 450hp period. You're rambling/talking out your neck now about things that aren't even relevant or being argued. Not sure what for. Like seriously, I didn't question it's performance. I never stated anything else about what engine should be where or anything. I simply stated that the CLS53 does not have 560lb-ft of torque or 450hp and that is unarguable no matter how much irrelevancy you try to pile on to obscure this fact.
and if they did take it to a track a good driver would beat them like a borrowed mule.
Absolutely! There will always be somebody with more experience, more modifications, better tires and more $$$ to spend on their vehicle. So take your car to the track, but just go there to enjoy the man-machine interface and have fun. If you have $$$ to spend, spend it on yourself and go take some driving school lessons. There is always something to learn unless you are Hamilton or Verstappen. (BTW -- many track events will not allow a convertible, even a retractable hardtop these days, unless there is a full roll cage installed. Liability against the organizers and insurance has become prohibitive.)
