I think it’s good to have the SL43. Not everyone needs over 400hp and we do need to be more green every way we can.
As I get older and richer I’ve been buying more powerful cars but I also find myself driving slower.
im going to seriously look at the 43, hopefully it will be at the NY Auto Show this month. I’m going

Initially I still think it is kind of slow for a vehicle of this caliber branded as an amg but then despite saying that, the GT 43 exists so I guess it is fine and the SL 43 replaces the SL 450 anyways so it is still appropriate.

Mercedes has been playing the moniker game for years now, deception in the name of marketing. Technically an 2.0 liter SL200 doesn't really sound good, so call it a 43. At the same time, a 2.0 liter AMG is a C63. Let's take something that was simple and make it super complicated.

That's cool, I don't disagree in that there is consistency lacking.

Nomenclature for the Germans has been well past sensible for years now. Even Audi who use to have just simple displacement badges on the back of their cars now use a completely confusing system using double digit numbers ranging from 30-70, luckily they don't put these badges on US cars. Cadillac is probably the worst, as they put torque badges on the back of their cars, but in newton meters, despite being an American brand who's sales are mainly in a country that doesn't use the metric system.
The nomenclature today is mainly driven by two factors, common engine downsizing, especially globally where one displacement size can be used in numerous states of power across different trims thanks to turbo chargers (most commonly, the 2.0L 4-Cylinder), as well as consumer driven as owners complained about the numbers on the back of their cars going down (for example, E350 to E300).

On the four cylinder issue- 2023 SL 43
381 + 14 (395) horsepower and 354 + 115 (496) pound-feet of torque. That’s why the 4.9 secs to 62mph. Nobody is mentioning the torque output of the 48v electric system.
My E53 cab system adds 22 hp and 184 pound-feet of torque.

The lack of horsepower is felt at higher range while engaging to pass or asking for instant acceleration, I can't imagine that experience bringing refinement or poise. Torque helps off the line, but 4.9 is sluggish (actually just plain slow) for a six figure AMG. So many performance cars beat this time easy. The outgoing non-AMG SL450 is faster, I believe 4.5(?). The 55 remains the sweet spot.

^ Horsepower and torque from the EQ system is included in their respective power curves. However, quoted horsepower and torque numbers are peak values on the curves, obtained at high RPM; the EQ system fattens up the curves at lower RPM.

The HP is FAR lower than that of the already powerful engine in the GLA A45-S. As to why they would not put the same tech in that engine and use it for this platform is surprising…if a 4-banger is what they wanted to use!?

Those numbers are not added in because the EQ system only assists in order to cut turbo lag, it is not counted or made for full overall output. The 381hp and 354lb-ft are the total numbers. It isn't making 395hp or 496 lb-ft of torque overall which is why it isn't counted in the overall tally.

Anyway, near 400hp/400ftlbs with a flat torque curve is plenty for me. The car looks great and the rest is academic. I have two guys at my golf club who have GTs and they drive only as fast as the golf carts, lol.

You can’t separate the HP made by the mild hybrid from the torque. If the electric motor is outputting it’s making both. Peak torque on the SL43 is at 1750rpm which is low so there is overlap and the two are accretive to some degree. When I bought my E53 Cab it added up both the HP and torque from both and that is what the advertising represented. I just looked back now and the 2022 only represents the 21 hp benefit. MB always said the hybrid part was only for 10 secs each time, but at 0-60 @ 4.1sec 10 gets you pretty fast.

No one is trying to separate anything, I'm telling that the overall peak numbers aren't what you tried to state they are. Not sure what you don't get here. No they didn't add up anything, not from Mercedes-Benz, that just simply isn't true. Now if your dealer or clueless salesperson did it then they were wrong. The EQ boost numbers are not part of the overall power ratings, not sure how else to say it. EQ is to counter lag, not overall system power. I mean look it up on any site about any engine with EQ Boost. I don't understand what you're even arguing about, you're just plain wrong and/or just don't understand the system.

I’ll explain what you are not understanding. At 1750 rpm you get full torque from the gas engine and the limited electric motor time frame (10secs) gets you past 1750rpm so they are both peaking at the same time. You understand that the electric motor drops off while the gas continues. Not complicated. I’ll draw a graph and post it for you.
When the new I6 debuted:
"A 48-Volt Integrated Starter/AlternatorThis engine is designed from the ground up to incorporate an integrated starter/alternator at the output end of the crankshaft. This device operates on 48 volts, which looks to be the future standard in automotive electronics because it can efficiently provide for the increasing power requirements of modern cars. For a given power level, increasing the voltage by a factor of four reduces the current by the same factor, which means that the thickness of the wiring used to carry the power can be reduced, saving cost and weight.
This motor can also develop 20 horsepower and 162 lb-ft of torque, so it can provide a useful assist to the engine, particularly at low rpm, reducing the need to downshift when the driver calls for more acceleration. It can also recover energy during braking to charge its 0.9-kWh lithium-ion battery. And such a powerful motor can quickly and effortlessly restart the engine during idle-stop mode.
In addition to this 48-volt system, there is a separate 12-volt electrical system—with its own small battery—to operate the numerous legacy 12-volt devices on the car. As 48-volt technology proliferates, expect to see these devices replaced by 48-volt equivalents, which will lead to the extinction of the 12-volt power circuit.
4. An Electric Supercharger
The M256 is turbocharged to develop high output from a small displacement, and that means there is the potential of turbo lag under some circumstances. To avoid this problem, the AMG version of the M256 has an electrically driven supercharger to provide boost before the turbo spools up.
This supercharger, which is located downstream of the turbocharger, uses a centrifugal flow compressor—like the compressor side of a turbo—driven by a 48-volt electric motor. It spins to 70,000 rpm and can develop a peak boost pressure of about 6.6 psi. That’s enough to provide strong engine response while the turbo gets up to speed, at which point a check valve closes and the turbo takes over from the electric supercharger."
This system is NOT DESIGNED for peak hp and torque output.

is an electric motor making power and that power propels the car, so it counts.
i understand where he/she is getting confused. Both gas and electric produce Hp and torque based upon their own mechanics and programming. And they aren’t designed to peak at the same time. I’m saying given the low rpm of peak torque from the gas engine 1750rpm, that they do for a 10 sec period until the electric motor disengages.
I will find a graph for both so you can see.
I drive an E53 with the same system and there were graphs in 2019. I do agree MBUSA is presenting this information differently now which is part of Germancar1 confusion
