Mercedes-AMG SL 43 Review: Is the Four-Cylinder Roadster a True AMG?
As a seasoned auto industry professional with over a decade immersed in the world of high-performance vehicles, I’ve had the privilege of witnessing firsthand the evolution of iconic models. The Mercedes-AMG SL, a nameplate synonymous with luxury and sporting prowess, has always held a special place in automotive history. But with the introduction of the SL 43, powered by a four-cylinder engine, a critical question arises: Does this “entry-level” variant uphold the prestigious AMG legacy? Let’s delve into a comprehensive review, examining the SL 43’s strengths, weaknesses, and its overall value proposition in the competitive luxury roadster market.
A New Era for the SL: Embracing Efficiency?
The Mercedes-AMG SL has undergone a significant transformation in recent years, shifting towards a sharper focus on performance while retaining its inherent grand touring character. The introduction of the SL 43 marks a departure from the traditional V8-powered lineup, embracing a smaller, more efficient engine. This move is undoubtedly influenced by tightening emissions regulations and the growing demand for fuel-conscious performance vehicles.
But can a four-cylinder engine truly deliver the visceral thrill and effortless power that AMG enthusiasts have come to expect? The SL 43 is equipped with a 2.0-liter turbocharged inline-four, enhanced by an electric exhaust gas turbocharger derived from Formula 1 technology. This innovative system aims to minimize turbo lag and enhance throttle response, resulting in a claimed output of 375 horsepower and 354 lb-ft of torque. These figures are certainly respectable, but how do they translate to the real-world driving experience?
Performance on the Pavement: Agile but Lacking Soul?
On a winding back road, the SL 43 exhibits a surprising level of agility and poise. The front end feels eager to turn in, and the steering is precise and responsive. The car’s relatively compact dimensions contribute to its nimbleness, making it feel more engaging than its larger V8 siblings in tight corners. The electric turbocharger does a commendable job of eliminating lag, providing instant power delivery that inspires confidence.
However, the absence of the V8’s thunderous soundtrack is immediately noticeable. While the four-cylinder engine produces a sporty growl, it lacks the depth and character that define the AMG experience. The sound is amplified through the quad exhaust tips, creating a somewhat artificial auditory experience that fails to truly stir the soul.
Furthermore, the SL 43’s powertrain can feel somewhat strained during everyday driving. The nine-speed automatic transmission, while generally smooth, occasionally hesitates to downshift, leaving the engine feeling out of its optimal power band. This can be particularly noticeable when attempting quick overtakes or merging onto the highway. While driving around town, the transmission calibration seems to be off, and at times, the throttle response, even in the chillest mode, is like a light switch, making it hard to creep away smoothly.
Luxury and Technology: A True SL Experience
Despite its smaller engine, the SL 43 doesn’t compromise on the luxury and technology that define the SL lineup. The interior is impeccably crafted, with high-quality materials and a modern, minimalist design. The 12.3-inch digital instrument cluster and 11.9-inch central touchscreen display provide a wealth of information and are seamlessly integrated into the cabin. The seats are comfortable and supportive, perfect for long-distance cruising, and the soft top can be lowered or raised in just 15 seconds at speeds up to 37 mph.
The exterior design of the SL 43 is equally striking, with its long hood, short rear deck, and muscular proportions. While subtle styling cues differentiate it from the V8 models, the overall aesthetic remains undeniably SL. Optional features such as larger wheels and a variety of paint colors allow buyers to personalize their SL 43 to their liking. The 43 gets slightly updated bumpers, although you’d have to be a real stickler for details to notice and a set of rounded exhaust tips. Aside from its updated badging, there aren’t many clear visual giveaways that you’ve opted for the least expensive model. This is great for those who appreciate the SL’s good looks but not its previously elevated price tag.
The Value Proposition: Is the SL 43 Worth the Savings?
The Mercedes-AMG SL 43 enters the market with a significantly lower starting price than its V8-powered siblings. This makes it an attractive option for buyers who desire the SL’s iconic styling and luxurious appointments but don’t necessarily require the outright power and performance of an AMG V8. The SL 43 opens up the new SL to a whole new price point and, most importantly, a broader market segment.
However, it’s crucial to consider the trade-offs. While the SL 43 offers a compelling blend of luxury and performance, it lacks the visceral excitement and effortless power that define the AMG driving experience. The four-cylinder engine, while technologically advanced, simply doesn’t deliver the same level of emotional engagement as a traditional V8.
Ultimately, the decision of whether to opt for the SL 43 comes down to individual priorities. If you prioritize fuel efficiency, agility, and a lower price point, the SL 43 is a worthy contender. However, if you crave the thunderous sound and relentless power of an AMG V8, you may find yourself longing for the SL 55 or SL 63.
Addressing the Competition: Luxury Roadster Market
The luxury roadster market is fiercely competitive, with offerings from Porsche, BMW, and Audi vying for the attention of discerning buyers. The SL 43 distinguishes itself with its iconic design, luxurious interior, and advanced technology. However, its four-cylinder engine may be a point of contention for some buyers, particularly those who prioritize performance above all else.
Porsche 718 Boxster: The Boxster is renowned for its exceptional handling and engaging driving dynamics. However, its base four-cylinder engine lacks the character of the SL 43’s unit. The Boxster GTS 4.0, with its naturally aspirated flat-six engine, offers a more compelling performance experience but comes at a higher price point.
BMW Z4: The Z4 offers a blend of sportiness and comfort, with a range of engine options to choose from. The Z4 M40i, with its inline-six engine, provides a more traditional performance experience than the SL 43. However, the Z4’s interior lacks the luxurious appointments of the SL.
Audi TT Roadster: The TT Roadster is a stylish and sporty convertible with a distinctive design. Its turbocharged four-cylinder engine provides ample power, but it lacks the refinement and character of the SL 43’s unit.

The Expert’s Verdict: A Promising Start with Room for Improvement
The Mercedes-AMG SL 43 represents a bold step for the SL lineup, embracing a smaller, more efficient engine without sacrificing the luxury and style that define the brand. While the four-cylinder engine may not deliver the same visceral thrill as a V8, it offers a compelling blend of performance and efficiency that will appeal to a wider range of buyers.
However, powertrain calibration issues aside, the rest of the SL 43 is as solid a package as its pricier counterparts.
The SL 43 proves that a car with great bones doesn’t necessarily need all the goodies to offer a great driving experience. And once the carmaker addresses powertrain missteps, I believe it can become the right car to complete the lineup.
To be clear, I wouldn’t write off this car based solely on its cylinder count. I may prefer the V8-powered SLs overall due to their charismatic sound and greater versatility, but this inline-four has plenty of character and deserves its spot under the SL’s hood, just not in its current state.
As a final thought, I’d encourage you to see for yourself. Visit your local Mercedes-Benz dealer and take the AMG SL 43 for a test drive, and be sure to explore Mercedes-Benz financing options and find the perfect luxury convertible to enhance your driving experience.
