Mercedes-AMG is planning a strategic shift for the SL-class. According to a report from Autocar, the upcoming refresh scheduled for next year will move the model away from its current aggressive, sports-car persona and return it to its heritage as a comfortable, high-end grand tourer.
A Shift in Identity: Sports Car vs. Grand Tourer
When the current generation of the SL launched in 2022, it underwent a fundamental change in character. By sharing a platform with the AMG GT Coupe, the SL became sharper, harder, and more focused on raw performance. While this appealed to driving enthusiasts, it distanced the model from its historical identity as a relaxed, long-distance cruiser.
The decision to pivot back toward luxury appears to be driven by market demand. Mercedes reportedly saw “overwhelmingly positive” feedback from the launch of the Mercedes-Maybach SL. This ultra-luxury trim emphasized opulence and a softer ride, proving that there is a significant appetite for an SL that prioritizes prestige and comfort over track-ready stiffness.
Powertrain Overhaul and Emission Compliance
The refresh will not just change how the car feels, but also what lies under the hood. Mercedes is restructuring its engine lineup to meet tightening European emissions standards and to better segment its models.
1. The End of the Four-Cylinder
The entry-level, four-cylinder SL43 is expected to be discontinued. To fill this gap, Mercedes-AMG will likely introduce an SL53 variant. This model will utilize a 3.0-liter inline-six engine, similar to the one found in the GLC53, providing a more substantial power base than the outgoing four-pot engine.
2. New V-8 Architecture
The high-performance V-8 models (the SL55 and SL63) are set for a major mechanical update. They will transition from a traditional cross-plane crankshaft to a flat-plane crankshaft design—a technology slated for the 2027 S-Class.
This change is critical for two reasons:
* Performance: Flat-plane cranks allow for higher RPMs and more aggressive power delivery.
* Regulation: The new design is engineered to comply with the strict Euro 7 emissions regulations arriving this fall.
3. Expected Power Outputs
While the focus is shifting toward “softness” in terms of ride quality, the raw power figures are expected to climb:
* SL55: Likely to produce approximately 530 hp.
* SL63: Rumored to see a significant jump to nearly 650 hp (up from the current 577 hp).
* Maybach SL680: Will likely feature a detuned V-8 producing just over 600 hp to maintain its luxury-first character.
The future of the high-performance plug-in hybrid, the SL63 S E Performance (805 hp), remains uncertain, with reports suggesting it may be discontinued entirely.
Why This Matters
This move highlights a broader trend in the automotive industry: specialization. As Mercedes-AMG pushes the GT Coupe further into the realm of pure performance, they are realizing that the SL needs its own distinct “soul” to avoid cannibalizing sales. By leaning into the “luxury cruiser” niche, Mercedes can capture a different demographic—those who want the prestige of an AMG but prefer a refined, effortless driving experience over a punishingly stiff suspension.
The upcoming Mercedes-AMG SL refresh represents a strategic return to form, trading aggressive track dynamics for the refined comfort of a classic grand tourer to better meet luxury market demands.
