2024 C63 S E Performance Boost/671 HP question
See the pics below from my car today. I have just over 3,400 miles on it so far. I use it in Boost Deactivated (yellow) mode in Race to get the full 671 hp when I want it and not just on kickdown.
Page 28 of the AMG Supplement
Boost Deactivated - Always using the Maximum Electrical Power
Boost Activated - For where max boost effect is needed exclusively via kickdown
Great way to see the HP and Torque by clicking on the Performance app
Tap on Engine at the top and you will see real time feedback from the cars performance.

Get into Race mode, battery 100% full and turn on the boost icon in blue as AMG manual mentioned, I drove in manual mode, I can feel a sudden boost stepping on the kick down switch!!
Take a look through the entire thread, all your questions are answered by other people asking the same thing!
Best of luck, drive safe!!
