Mercedes-AMG SL 43: A Performance Bargain or Compromised Roadster?
As an industry veteran with a decade immersed in the world of high-performance automobiles, I’ve witnessed firsthand the evolution of iconic models. The Mercedes-AMG SL, now in its seventh generation, represents a fascinating shift, trading the “Benz” moniker for the raw performance focus of Affalterbach. This rebirth, characterized by a unique architecture, engine, and aesthetic, aims to recapture the SL’s sporting spirit, albeit within a decidedly modern, luxurious framework.
This revitalized SL, while undeniably more engaging than its predecessor, comes with a steeper price tag. The SL 55, previously the entry point, started north of $140,000, while the flagship SL 63 easily crests $180,000. This left a significant void, prompting the arrival of the Mercedes-AMG SL 43. Starting around $111,000 (including destination), the SL 43 promises a more accessible entry into the world of AMG roadsters. But does this affordability come at the cost of the SL’s core essence? That’s the million-dollar question, and the answer, as I discovered during my extensive test drive, is nuanced.
The Heart of the Matter: A Turbocharged Four-Cylinder
The defining feature of the SL 43 is undoubtedly its engine. Eschewing the familiar AMG 4.0-liter V8, the SL 43 adopts a 2.0-liter turbocharged inline-four. It’s a similar unit to those found in AMG’s “45” series models, but with a twist – an electric turbocharger. Directly derived from Formula 1 technology, this innovative system incorporates a small electric motor positioned between the turbine and compressor wheels. This allows for near-instantaneous turbo spool-up, drastically improving throttle response and eliminating dreaded turbo lag. This is particularly important for the Mercedes-Benz roadster experience.
The result is a respectable 375 horsepower and 354 pound-feet of torque. While that may seem modest in a grand tourer flirting with the 4,000-pound mark, this inline-four is a surprisingly potent powerplant. Paired with a responsive nine-speed multi-clutch automatic transmission, the SL 43 delivers power with confidence, even with its rear-wheel-drive configuration. While it lacks the all-wheel-drive system and torque-vectoring capabilities of its pricier siblings, the engine’s eager nature and responsive delivery might make you forget the horsepower deficit. This smaller engine also impacts fuel efficiency, making the SL43 a slightly more practical choice for everyday driving.
The soundtrack emanating from the quad exhaust tips, while not as sonorous as the V8’s guttural roar, is still engaging. It’s a loud, buzzing growl with plenty of turbocharger noises, adding a layer of excitement to the driving experience. It’s a distinct AMG signature, even if it’s not the traditional V8 rumble.
Hitting the Curves: Agility and Balance
On a winding back road, the SL 43 proves its mettle. Despite not being significantly lighter than its V8-powered counterparts, it retains much of the agility and balance that defines the SL lineage. The front end offers tremendous grip and eager turn-in response. Coupled with a quick steering system, the SL 43 dives into corners with confidence and minimal body roll. Remarkably, it achieves this without relying on active suspension components, relying instead on a traditional setup of shocks and steel springs. This simpler setup enhances the feeling of connection with the road, which is vital for a true driver’s car.
Everyday Living: Compromises in Refinement?
While the SL 43 excels when pushed hard, it falters slightly in the areas where a grand touring convertible should shine – everyday comfort and refinement. The turbocharged four-cylinder, while characterful in Sport+ mode, doesn’t fully quiet down in the more relaxed Comfort setting. Its high-strung nature becomes apparent at stoplights, where unwanted vibrations can be felt through the car.
Around town, the engine and transmission occasionally feel out of sync. The throttle response, even in the most subdued mode, can be abrupt, making smooth acceleration challenging. Demanding a sudden burst of speed often results in a noticeable delay as the nine-speed transmission hunts for the appropriate gear. The SL 43, therefore, lacks the true dual-personality of the SL 55 and SL 63. It’s exhilarating when driven aggressively but less composed during everyday commutes. This characteristic might be a deal-breaker for those seeking a truly versatile grand tourer, and it’s an area where Mercedes-AMG needs to invest further development efforts.
The Visual Appeal: Maintaining the SL Aesthetic
Fortunately, the cost-saving measures implemented in the SL 43 haven’t compromised its striking aesthetics. The overall design and cabin layout remain largely unchanged. The SL 43 boasts the same stunning proportions that make the SL so visually appealing. Minor updates to the bumpers and exhaust tips differentiate the 43, but only the most discerning enthusiasts will notice the changes. This is a significant advantage for those drawn to the SL’s captivating design but previously deterred by its high price.
The interior is equally impressive. The 12.3-inch digital instrument cluster and 11.9-inch central touchscreen are identical to those found in the more expensive models, as are the seats and retractable soft top. The cabin effectively isolates occupants from wind and road noise, and at higher speeds, with the engine operating at lower RPMs, it’s surprisingly quiet.
The SL 43’s cabin showcases Mercedes-Benz’s expertise in crafting world-class interiors. The soft top retracts in just 15 seconds at speeds up to 37 mph, allowing for an impromptu open-air driving experience.
The Verdict: A Worthy Addition or a Compromise Too Far?
The crucial question for any prospective SL 43 buyer is whether the price reduction justifies the trade-offs. Taking my test vehicle’s as-tested price of around $120,000 as an example, it’s a significant $100,000 less than the SL 63 I evaluated last year. Yet, the “entry-level” model is just as visually stunning, and its cabin is equally luxurious, with many of the same optional features available. If anything, the SL 43 broadens the SL’s appeal by targeting a more accessible price point and a wider market segment.
The SL 43’s current shortcomings primarily stem from the engine and transmission calibration. These are issues that Mercedes-AMG can address and refine in future model years. I wouldn’t dismiss this car solely based on its cylinder count. While I 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 with some fine-tuning.
Ultimately, the SL 43 demonstrates that a car with excellent fundamentals doesn’t necessarily require all the bells and whistles to deliver a satisfying driving experience. Once Mercedes-AMG resolves the powertrain issues, I believe the SL 43 has the potential to become a compelling addition to the SL lineup.
