The 2025 Mercedes-AMG SL 43: A True Bargain or a Compromised Roadster? An Expert’s Take
For over a decade, I’ve been entrenched in the automotive world, witnessing the evolution of performance vehicles firsthand. The Mercedes-AMG SL has always held a special place, a symbol of luxury and exhilarating performance. But with the introduction of the SL 43, powered by a four-cylinder engine, a crucial question arises: does it dilute the SL legacy, or does it democratize access to this iconic roadster? Let’s dive deep into the 2025 model, beyond the marketing hype, and get to the truth.
The AMG SL Legacy: A Shift in Focus
The seventh-generation Mercedes-AMG SL marked a significant departure, embracing a more athletic and driver-focused character. This shift, while welcomed by enthusiasts, elevated the price point considerably. The SL 55 and SL 63 commanded hefty price tags, creating a void in the lineup for those seeking the SL experience without breaking the bank.
Enter the Mercedes-AMG SL 43. Starting at a more accessible price, it promised to bridge the gap. However, this affordability comes with key trade-offs: a smaller engine, rear-wheel drive instead of all-wheel drive, and the omission of advanced features like torque vectoring and active anti-roll bars. The big question remains: can the SL 43 truly deliver the essence of the SL experience?
The Heart of the Matter: The Four-Cylinder Engine
The 2025 SL 43’s defining feature is its 2.0-liter turbocharged inline-four engine, a departure from the traditional V8s. This isn’t just any four-cylinder; it’s equipped with an electric turbocharger, a technology derived from Formula 1. This innovative system significantly reduces turbo lag, resulting in sharper throttle response and enhanced overall performance.
The engine churns out a respectable 375 horsepower and 354 pound-feet of torque. While these figures might seem modest for a grand tourer weighing around 4,000 pounds, the SL 43’s powertrain is surprisingly energetic and responsive. The nine-speed automatic transmission executes quick, seamless shifts, ensuring that the engine remains in its sweet spot. The car’s agility, balance, and eagerness to change direction, aided by precise steering, are hallmarks of the SL driving experience.

The Sound and the Fury: Exhaust Note and Driving Dynamics
While the SL 43’s exhaust note doesn’t possess the visceral rumble of a V8, it’s still a pleasing and surprisingly aggressive sound. The turbocharger adds a distinctive whoosh and whine, further enhancing the driving experience.
Out on winding roads, the SL 43 shines. Its lighter front end makes it remarkably agile, and the absence of active suspension doesn’t detract from its handling prowess. The car remains composed and balanced, inspiring confidence in every turn.
The Compromises: Where the SL 43 Falls Short
Despite its strengths, the SL 43 isn’t without its flaws. The engine’s refinement leaves something to be desired, especially in everyday driving situations. In Comfort mode, the engine never truly quiets down, and unwanted vibrations can be felt at idle.
The powertrain calibration can also be problematic. The throttle response can be abrupt, making smooth acceleration challenging, and the transmission can be hesitant to downshift when needed. As a result, the SL 43 lacks the dual-personality of its V8-powered siblings, excelling at high-speed driving but faltering in more relaxed settings.
Interior and Exterior: A Familiar SL Experience
Fortunately, most of the cost savings in the SL 43 are concentrated under the hood. The exterior design remains largely unchanged, with sleek lines and aggressive styling. Subtle differences, such as updated bumpers and round exhaust tips, are barely noticeable.
Inside, the SL 43 offers the same luxurious and well-appointed cabin as its more expensive counterparts. The 12.3-inch digital instrument cluster and 11.9-inch central touchscreen provide a modern and intuitive user experience. The seats are comfortable and supportive, and the retractable soft top operates quickly and efficiently. The quality of materials, fit, and finish are excellent.

Is the Price Discount Worth It? A Balancing Act
The ultimate question is whether the SL 43’s price discount justifies its compromises. In my opinion, the answer is a qualified yes. While the engine’s refinement and powertrain calibration need improvement, the SL 43 offers a compelling blend of performance, luxury, and style at a more accessible price point.
Compared to the SL 63, the SL 43 represents a significant cost savings without sacrificing the core elements of the SL experience. It looks just as good, has a cabin just as nice, and delivers a rewarding driving experience.
The Future of the SL 43: Potential for Improvement
The SL 43’s shortcomings are primarily related to its engine and transmission tuning. Fortunately, these are issues that Mercedes-AMG can address with software updates and future model year refinements.
With improved powertrain calibration, the SL 43 has the potential to become a truly exceptional roadster. It already possesses the chassis, styling, and interior to compete with the best in its class. By ironing out its rough edges, Mercedes-AMG can transform the SL 43 into a true champion.

The Verdict: A Promising Roadster with Room to Grow
The 2025 Mercedes-AMG SL 43 is a promising roadster with a few key areas for improvement. Its four-cylinder engine delivers surprising performance, and its handling is sharp and engaging. While it lacks the visceral appeal of a V8, it offers a more accessible entry point into the SL lineup.
If you’re looking for a stylish, luxurious, and sporty convertible without the hefty price tag of the SL 55 or SL 63, the SL 43 is worth considering. Just be aware of its powertrain quirks and hope for future refinements.
