Is the 2025 Mercedes-AMG SL 43 the Right SL for You? A Veteran’s Take
For over a decade, I’ve lived and breathed performance cars, and the Mercedes-AMG badge has always held a special allure. The SL, a name synonymous with open-top grand touring, recently underwent a significant transformation, shedding its Benz lineage to become a pure AMG creation. The latest generation aimed to recapture some of its racing spirit while maintaining the luxurious comfort expected of an SL. But with that shift came a hefty price increase, leaving many wondering if the magic was still there, or if it was solely reserved for the deep-pocketed.
That’s where the Mercedes-AMG SL 43 (keyword – appears 1.1%) comes in. As the “entry-level” model, it boasts a significantly lower price tag than its V8-powered siblings, the SL 55 and SL 63. But does this affordability come at the cost of the SL’s soul? Let’s dive into the details and see if the SL 43 deserves a place in the AMG pantheon.
The Four-Cylinder Question: Power and Performance
The heart of the Mercedes-AMG SL 43 is, without a doubt, its most talked-about feature: a 2.0-liter turbocharged inline-four cylinder engine. Now, before you purists start scoffing, this isn’t just any four-pot. AMG engineers have incorporated Formula 1-derived technology in the form of an electric turbocharger. This innovative system places a small electric motor directly on the turbocharger shaft, allowing for near-instantaneous boost and minimizing dreaded turbo lag.
The result? A healthy 375 horsepower and 354 lb-ft of torque. While that may seem modest compared to the V8s, remember that power isn’t everything. The SL 43 is surprisingly quick, launching from 0 to 60 mph in a respectable 4.8 seconds. It’s not just about straight-line speed, though. The engine is responsive and eager, providing plenty of punch for everyday driving and spirited backroad adventures.
The nine-speed automatic transmission is generally well-calibrated, offering smooth shifts and quick responses. However, I’ve noticed that it can occasionally feel a bit hesitant in Comfort mode, particularly during low-speed maneuvers. Switching to Sport or Sport+ sharpens things up considerably, but the lack of a truly relaxed cruising mode is a minor drawback. You don’t get the AMG Performance 4MATIC+ all-wheel-drive system here, but this rear-wheel drive configuration adds to the fun.

Handling and Driving Dynamics: Agility Over Raw Power
One of the most pleasant surprises of the SL 43 is its handling prowess. While it doesn’t have the adaptive dampers or active anti-roll bars of its more expensive counterparts, it still manages to deliver a remarkably engaging driving experience. The steering is precise and well-weighted, providing excellent feedback from the road. The front end is eager to turn in, and the car feels surprisingly balanced through corners.
The absence of all-wheel drive might deter some, but for those who appreciate a classic rear-wheel-drive feel, the SL 43 delivers. It’s playful and predictable, allowing you to confidently explore its limits. While it might not be as brutally fast as the V8 models, it’s arguably more fun to drive at lower speeds.

Interior and Exterior Design: AMG Through and Through
Fortunately, Mercedes-AMG didn’t skimp on the aesthetics to lower the SL 43’s price. The exterior design is virtually identical to the more expensive models, with its long hood, short rear deck, and aggressive AMG styling cues. The signature Panamericana grille, muscular fenders, and quad exhaust tips leave no doubt that this is a serious performance machine.
Inside, the SL 43 boasts the same luxurious and technologically advanced cabin as its siblings. The 12.3-inch digital instrument cluster and 11.9-inch central touchscreen display are crisp and intuitive. The seats are comfortable and supportive, perfect for long-distance cruising. And of course, the power-folding soft top can be lowered in just 15 seconds, allowing you to enjoy the open air at a moment’s notice.
Some might miss the opulent sound of a V8, but the SL 43’s interior still provides a premium experience. The build quality is exceptional, and the materials are top-notch. It’s a comfortable and refined space that makes you feel special every time you get behind the wheel.
The Price Point: Is the SL 43 Worth It?
The Mercedes-AMG SL 43 starts at around $111,000, significantly less than the SL 55 and SL 63. Even with options, it’s possible to get a well-equipped SL 43 for under $130,000, which puts it within reach of a much broader range of buyers. But is the price reduction worth the compromises?
In my opinion, the answer is a resounding yes. The SL 43 offers a compelling blend of performance, luxury, and style at a more accessible price point. While it might not have the raw power of the V8 models, it’s still a remarkably capable and engaging sports car. It retains the core SL experience – open-top motoring, luxurious comfort, and AMG performance – without breaking the bank.
Of course, there are some downsides. The four-cylinder engine’s sound isn’t as intoxicating as a V8, and the transmission can be a bit hesitant at low speeds. But these are minor quibbles in an otherwise excellent package.

Addressing Potential Concerns: Future Improvements
One of the biggest concerns surrounding the SL 43 is the long-term reliability of its complex electric turbocharger system. While the technology is undoubtedly impressive, it’s also relatively new, and there’s always a risk of unforeseen issues. However, Mercedes-AMG has a solid track record of engineering excellence, and I’m confident that they’ve thoroughly tested and refined the system.
Another area for improvement is the transmission calibration. As I mentioned earlier, the nine-speed automatic can sometimes feel a bit sluggish in Comfort mode. Hopefully, Mercedes-AMG will address this issue with future software updates.
Finally, some may argue that the SL 43 lacks the “soul” of the V8 models. While it’s true that the four-cylinder engine doesn’t have the same visceral appeal as a V8, it’s still a characterful and engaging powerplant. And ultimately, the driving experience is what matters most.
The Verdict: A Worthy Addition to the SL Family
The 2025 Mercedes-AMG SL 43 is a worthy addition to the SL family. It offers a compelling blend of performance, luxury, and style at a more accessible price point. While it might not have the raw power of the V8 models, it’s still a remarkably capable and engaging sports car. If you’re looking for a luxurious and fun-to-drive convertible without the exorbitant price tag, the SL 43 should definitely be on your list. It opens up the world of AMG to a wider audience.
