SL/R231: AMG Performance Suspension with 2 stage adjustment
As the recent owner of 2019 SL63 I looked into this considerably mysterious $1500 option. The question was first asked by the member in 2018, who accidentally posted it in the wrong forum (R230).
Here is what I found after a bit of digging. I hope it may address some unanswered questions.
Below is the excerpt from the MB own brochure on 2018 SL:
Competitive spirit, superlative specs.
Based on Active Body Control, the AMG Performance Suspension teams advanced electronics and hydraulics to actively counteract pitch, dive and roll with millisecond-quick response and multiple modes. An optional setup adds two-stage damping that’s also 30% firmer damping in Sport mode. Silver or optional red calipers grasp the 15.4" front/14.2" rear composite brakes. Even larger yet lighter Ceramic Composite brakes are an option proven in racing.
In the second sentence MB implies that AMG performance suspension is fitted in every AMG SL. In the third they talk about optional two stage dumping that is 30% more firm in the sport mode. From other posts we know that there are both the software and the hardware differences between the cars fitted and not with this option. The way I read it, sometime in 2018 the “option” became part of the standard equipment but MB continued to separately charge for it and all there is is a 30% firmer dampers when set in sport mode but not so in comfort mode. This would explain why MB has been so vague with their answers related to this matter. I have not seen a single sticker on Autotrader that did not have this option included in the build on 2019 SL63s and I have seen many.
