Mercedes-AMG Bringing Back Grand Touring Feel to the SL

The move is to more clearly define the SL models from the hard-top GT models.

According to a report by Autocar, the Mercedes-AMG SL will be softened as part of the seventh-generation facelift scheduled for next year. Mercedes-AMG is taking a deliberate step back from outright aggression and repositioning the SL as something it historically did better than almost anything else: a refined, open-top grand tourer. The shift is meant to give the SL a stronger identity. The current SL shares much of its DNA with the Mercedes-AMG GT, including platform, drivetrains, and chassis components. While that made for a sharper, more performance-focused SL, it also blurred the lines between two very different cars. Now, AMG wants to create clearer separation, letting the GT be the hardcore sports machine while the SL leans into comfort, luxury, and effortless speed.

The decision isn’t being made on a whim. Insiders point to the overwhelmingly positive reception of the Mercedes-Maybach SL as a key influence. That model proved there’s strong demand for a softer, more indulgent SL experience. An SL that prioritizes cruising comfort without sacrificing presence or performance.

Changes Under the Hood

Under the hood, the changes are just as significant. The entry-level SL 43 is expected to disappear, taking its turbocharged four-cylinder engine with it. In its place comes a new SL 53, powered by a revised 3.0L inline-six producing around 450 horsepower. It’s a move that better aligns with AMG buyer expectations, more cylinders, more character, and a smoother delivery of power.

V8 models are also getting a major rethink. Both the SL 55 and SL 63 will transition from traditional cross-plane crankshafts to flat-plane designs. That’s a big shift, one driven largely by tightening emissions regulations in Europe. The result? Cleaner performance without neutering output. Expect around 537 horsepower from the SL 55 and close to 650 horsepower from the SL 63, an increase of about 70 horsepower over the current car.

Electrification

It should not come as any great surprise that electrification will play a role across the board in the updated SL. Every model is set to adopt mild-hybrid technology, featuring a starter-generator mounted ahead of AMG’s nine-speed automatic transmission.

This setup improves efficiency and responsiveness, while helping the SL meet upcoming Euro 7 emissions standards. The fate of the plug-in hybrid SL 63 SE Performance remains uncertain, with some insiders suggesting it may be phased out.

Design Changes

Visually, the updates will be subtle but meaningful. Expect revised front and rear lighting with Mercedes’ latest star-pattern graphics, along with small tweaks to keep the SL looking fresh. Inside, the cabin will benefit from the brand’s new MB.OS infotainment system, updated displays, and a redesigned steering wheel, bringing it in line with Mercedes’ latest tech-forward interiors.

Ultimately, this evolution feels like a course correction rather than a compromise. The SL isn’t losing its performance edge, it’s simply rediscovering its purpose. For enthusiasts who appreciate both speed and sophistication, that balance might make the next-generation SL more compelling than ever. For the hardcore performance fans, the GT is still an option.
