Mercedes launched the six-generation SL-Class for the 2012 model year. Compared to the previous generation, the 2012 was advanced in a number of ways, with the most important being the near all-aluminum body. It came with a design that screamed sport in comparison, the engine was more powerful, and that near all-aluminum body dropped the SL’s curb weight by more than 240 pounds. This was great for the powerful roadster, but now that the 2015 L.A. Auto Show has kicked off, Mercedes has introduced a facelifted roadster. This facelift was also carried over to the AMG branded models, which should be available sometime in 2016 for the 2017 model year. When the 2017 models hit showrooms, we’ll get two AMG variants here in the States – the SL63 and SL65.
