There will be no more SL63 for 2020. This comes after the sad news of the death of the V12 powered SL65 AMG last year. The SL will lack an AMG version or the first time since 1995.
This is most likely due to poor sales, and the AMG GT Roadster eating up the marketshare. They fill the same role, except the SL63 is more low-key and stealthy.
Rumors were spreading that the SL63 would be axed, but PR Specialist at Mercedes USA has confirmed the news to CarBuzz that "we do not have MY20 SL63." For those of you who don't speak PR, MY stands for model year, meaning the 2019 model year is the last one available for the SL63.
Personally, I liked the Sl63. It was stealthy, a really fast car that can blend in with the crowd unless people heard the roaring exhaust note. It's sad but understandable that the SL has met its demise. It will be missed.
