Mercedes Cranks the Wick on AMG SL to 1,047 Lb-ft

Be honest. When one thinks of vehicles with four-figure levels of torque, heavy-duty pickup trucks tend to spring immediately to mind. But now we can add a Mercedes-Benz to that roster - and it comes from the most unlikely of segments. 


Enter the *inhales* 2024 Mercedes-AMG SL 63 S E PERFORMANCE *exhales*. Someone in Stuttgart must have a brother who owns a letter making business in need of a boost. At any rate, this ragtop is apparently good for 805 horsepower and a staggering 1,047 lb-ft torque peak, courtesy of a V8 engine and hybrid gubbins. 


We find a 4.0-liter biturbo octopot under that swollen bonnet, appended by an electric drive unit on the rear axle contributing 201 hp to the equation. That motor dances with a two-speed transmission whilst the V8 deals with a nine-speed that’s been fettled by AMG. Note well: there remains a mechanical connection of the AMG Performance 4MATIC+ all-wheel drive system, meaning the electro guts can shuffle power to the front wheels under certain conditions. There’s a 6.1kWh battery in the mix, as well. Tech is wonderful. 

How wonderful? How about 0 - 60 mph in just 2.8 seconds type of wonderful? Top speed is electronically limited to 196 mph and speeds are brought back to sanity by six-piston calipers up front with 16.5-inch carbon ceramic discs. 


It’s worth saying that while the four-figure torque gets all the headlines, there is a notation that “system torque” ranges from 797 lb-ft up to the stated maximum. That, of course, is still nothing at which to sneeze. There are all manner of driving modes, of course, including an all-electric though Merc has yet to say how far this thing will get on electrons alone thought they do make the effort to point out the battery is designed for fast power delivery and draw rather than longest possible range. Good enough for tootling around Rodeo Drive, at least. And yes, that is a charging port on its rump.

Having driven the SL 63 in California when it showed up on the market about two years ago, this author can confidently say the thing is not wanting for a bit of power. Jacking twist to 1,047 lb-ft is sure to turn the brute in a suit into an even more fearsome weapon in which to terrorize sun-soaked coastal roads or wherever the nation’s 1% choose to live these days. The presence of active ride control and rear-axle steering should also help Hollywood elites from wadding this thing up on the streets of Malibu too quickly.


Merc says the 2024 Mercedes-AMG SL 63 S E PERFORMANCE will appear at American dealerships in the upcoming calendar year.

    Grotesque from every angle.

      Agree. It's a performance monster, and a convertible to boot. It's a shame that it looks terrible. Whatever happened to the class that MB used to exude? It has diminished steadily over the decades, and now is in negative territory.

    If you are interested in one of these, ToolGuy recommends the lease. 😉

      No worries... your bicycle back in high school had two transmissions.


  • Daniel J This thing is just too big and not packaged great being RWD. I'd prefer a FWD/AWD pre 2024 Santa Fe sized vehicle. A true CX-70.
  • Ash78 Now that we're on the topic, I think Apple owes us all a ton of money for bringing out new phones every 1-2 years and devaluing the one I have! /sDepreciation has always been a part of car ownership, far more so now if you're getting into EVs. I think it's just the discrete nature of these depreciation events (ie, price cuts) that have everyone wringing their hands.I'm too price sensitive -- not necessarily to BUY an EV -- but for the fear of what a truly disruptive battery tech might do to them. Split the differene with a hybrid or PHEV and you've reduced your car's reliance on battery tech as the primary determinant of value.
  • Ash78 Interesting take on the pricing...superficially illogical, but Honda has been able to sell the Pilot Junior (er, Passport) for more than the Pilot for several years now. I guess this is the new norm. I have 2 kids, who often have friends, and I feel like the best option here is buying the CX-90 and removing the third row completely. It won't be pretty, but it adds useful space. We've done that in our minivan several times.I've been anxiously awaiting the 70 for over a year, but the pricing makes it a non-starter for me. I like the 50, but it's tight (small, not dope/fire/legit); I like the 90s, but it's more than we need. This "Goldilocks Solution" feels like it's missing the mark a little. Mazda could have gone with more of a CX-60 (ROW model) and just refreshed it for the US, but I suspect the 90 was selling so well, the more economical choice was just to make it the same basic car. Seems lazy to me.
  • FreedMike If you haven't tried out the CX-90, do so - it's a great driver, particularly with the PHEV powertrain.
  • Ajla I don't understand why it is priced above the CX-90 (about $2500 at every trim level on the I6 and $5k on the PHEV), unless a CX-90 price increase is on the way soon. It will be interesting to see how this does against the CX-90, that one isn't packaged well for a 3-row but with a lower price, very similar exterior styling and identical exterior dimensions I'd lean towards it over the 70. The pricing on higher trims is a bit dear for a nonpremium badge and it is annoying that Mazda and the press pretend that the lower nonS trims don't even exist. Why even bother making them if you won't take it to your own media event?I would expect the engine and chassis configuration to be a killer app here but it seems like engine/transmission is only 80% baked and the interior is what sells these. Reliability is a big question mark as well. In the end outside of a specific buyer (this seems like something Corey would like), I'd recommend getting something cheaper and more established.
