SL63-What was the update around 2015?

[ack0]

Looking at these around 50K and can see that there is a power hike around this time
Were there any other changes?
Thx

I bought a 2015 early this year. The performance pack which bumped the power from 535 to 567 was discontinued for the 2015 model, and the standard power was hiked to 577bhp and 664lb/ft of torque, a big jump on the original especially the torque.
I am not sure about standard equipment changes, but I believe there were no other significant mechanical changes.
Stonking car, a huge leap forward from the previous generation R230 series speaking from experience.
