The 2025 Mercedes-AMG SL 43: A Reputable Option?
After a decade immersed in the luxury automotive sector, specifically with Mercedes-Benz and AMG, I’ve seen firsthand how product line extensions can either elevate a brand or dilute its core essence. The Mercedes-AMG SL, now in its seventh generation (R232), underwent a significant transformation, embracing its AMG identity with a unique architecture, engine, and design. This revitalized SL aimed for a sportier driving experience, a departure from its more luxurious GT predecessors. However, this shift also brought a steeper price tag, raising the question: Can a four-cylinder SL truly fill the void and appeal to a broader audience?
The SL 55 and SL 63, with their potent V8 engines, set a high bar for performance and luxury, but their starting prices of $142,450 and $183,000 respectively, placed them out of reach for many enthusiasts. Enter the Mercedes-AMG SL 43, boasting a starting price of $111,050. This more accessible model aims to bridge the gap, but it does so by swapping the renowned V8 for a turbocharged four-cylinder engine and ditching standard all-wheel drive, torque vectoring, and active anti-roll stabilization.
The Heart of the Matter: Engine and Performance
The defining feature of the SL 43 is undoubtedly its engine: a 2.0-liter turbocharged inline-four. While it shares similarities with the engines found in AMG’s “45” models, the SL 43 distinguishes itself with an innovative electric turbocharger, a technology derived from Formula 1. This electric turbocharger incorporates a small electric motor positioned between the turbine and compressor wheels. Its purpose? To rapidly spool up the turbo, drastically minimizing lag and sharpening throttle response.
This advanced engine delivers 375 horsepower and 354 pound-feet of torque. Now, I know what you’re thinking: is that enough for a two-door roadster flirting with the 4,000-pound mark? The answer, surprisingly, is a resounding yes. This inline-four is a spirited and eager performer, exceeding expectations. Paired with a responsive nine-speed multi-clutch automatic transmission, the SL 43 confidently delivers its power to the rear wheels. Although it falls short of the SL 55’s 469 hp, the engine’s responsiveness and eagerness to unleash its power make the difference negligible for most drivers. High-performance enthusiasts, or those who really need a speed fix, might think otherwise.
And let’s talk about the sound. While it doesn’t possess the thunderous rumble of the V8-powered SLs, the exhaust note is far from disappointing. It’s a loud, buzzing growl with distinct turbo whooshes, adding a layer of drama to the driving experience. Of course, this is one of those things that is completely subjective. Some might not find the sound profile as appealing as others might.
Handling and Driving Dynamics: A Twist in the Tale
When you encounter a winding back road, the SL 43 continues to impress. While not significantly lighter than its V8 counterparts, it retains much of the agility and balance that define the SL family. The front end is remarkably grippy and eager to change direction, while the responsive steering system allows the car to confidently dive into tight corners with minimal body roll. What’s truly impressive is that it achieves this level of performance without relying on active suspension components, relying instead on a well-tuned combination of traditional shocks and steel springs.
However, the SL 43 encounters challenges in areas where a grand touring convertible should excel. The engine, while exciting in Sport+ mode, struggles to settle down in Comfort mode. Its high-strung nature becomes apparent at stoplights, where unwanted vibrations can be felt throughout the car.
During relaxed city driving, the engine and transmission sometimes seem at odds. The throttle response can be overly sensitive, even in the most relaxed settings, making smooth starts difficult. Demanding sudden acceleration can result in a noticeable delay as the nine-speed transmission hunts for the right gear, leaving the engine feeling a step ahead. This inconsistency prevents the SL 43 from achieving the dual-personality of its V8 siblings. It shines when driven aggressively, but its composure falters at lower speeds.
Exterior and Interior: The Alluring Appeal
Despite the powertrain quirks, the SL 43 maintains the solid foundation of its more expensive siblings. Most of the cost savings appear to be concentrated under the hood, leaving the overall aesthetic and cabin layout largely unchanged. The car retains its stunning looks and well-proportioned design. Subtle updates to the bumpers and rounded exhaust tips are the only visual cues that distinguish it from its pricier counterparts.
Stepping inside reveals a similar story. The 12.3-inch digital instrument cluster and vertically oriented 11.9-inch central screen are identical to those found in other SL models, as are the seats and retractable soft top. Engine vibrations aside, the cabin is well-insulated from wind and road noise. At higher speeds, with the engine at lower revs, the cabin is surprisingly quiet.
The SL 43’s interior showcases Mercedes-Benz’s expertise in crafting world-class cabins. The soft top can be lowered in just 15 seconds at speeds up to 37 mph.
The Verdict: A Worthwhile Compromise?
The fundamental question for anyone considering the SL 43 is whether the price reduction justifies the compromises. To address this, let’s examine the as-tested price of my evaluation unit: $119,785. This is nearly $100,000 less than the SL 63 I tested last year. Despite the significant price difference, the “entry-level” model retains the same attractive styling and a comparable interior, with many of the same optional materials available. The SL 43 broadens the SL’s reach to a new price point and, more importantly, a wider audience.
I emphasize “most likely” because the SL 43’s current issues primarily stem from the calibration of its engine and transmission. These are the kinds of refinements that Mercedes-AMG can implement in future model years. I wouldn’t dismiss this car based solely on its cylinder count. While I may prefer the V8-powered SLs for their charismatic sound and greater versatility, this inline-four possesses its own unique character and deserves its place under the SL’s hood, albeit in a more refined state.
Ultimately, the SL 43 demonstrates that a car with a strong foundation doesn’t require all the bells and whistles to deliver a satisfying driving experience. Once Mercedes-AMG addresses the powertrain inconsistencies, the SL 43 has the potential to be the perfect addition to the lineup, for the luxury car enthusiast and AMG lover.
