Subsequent to the prototypes spotted earlier this year, Mercedes-Benz has officially acknowledged that the SL is getting renewed for yet another generation.

The new generation of the car has officially entered the road-testing phase, and Mercedes has marked the advancement in the development with a few official ‘scoops’ showing the pre-production cars on German roads. This time around, the SL will be a dedicated Mercedes-AMG model instead of having separate AMG variants. Thus, it will be marketed as the Mercedes-AMG SL.

“The next generation of the legendary SL Roadster is going back to its roots, which lay in motorsport back in 1952. Mercedes-AMG, as the performance and sports car brand of Mercedes-Benz AG, has fittingly taken on the task of overall vehicle development for the reinterpretation of the legendary roadster”, the company noted.

“Following extensive digital development steps, test stand runs and simulator trials, the new sports car is now entering a scheduled phase of wide-ranging dynamic driving tests – thus far at the Group’s own Test and Technology Center in Immendingen – and now also on public roads in some cases.”

Expected to launch next year, likely as a 2022 model, the all-new SL appears to drop the folding metal roof in favor of a soft top, while some unconfirmed reports have indicated that it might add two small rear seats. Developed by Mercedes-AMG, it will be built on the Modular Sports Architecture (MSA) platform of the next-gen GT sports car, and should provide a good balance between comfort and sportiness.

The engine lineup has yet to be confirmed, but it might include a 429 HP 3.0-liter six-pot, alongside a 515 HP twin-turbo 4.0-liter V8, as well as the 604 HP variant of AMG’s V8 in the SL 63. Sitting at the top of the range could be the SL 73 performance plug-in hybrid with up to 800 HP.
