have had my 2015 e63 for about 18 months now with 23k miles on it and have never fully figured out the transmission mode differences.

i found this interesting article about the transmission modes and assuming its accurate would make me try to drive more in M (manual) mode if that is the fastest shift setting.

i typically drive in S+ which feels solid ripping through 1-2-3rd gears and fast, but i get a noticeable blip/pause (with exhaust bark) as it goes from 3rd to 4th gear in S+ mode at WOT which i would assume should be seamless and much smoother.

Here's the article - would welcome any other readings that help explain the trans modes if there is more to explain than what is written up here - cheers J

"MCT stands for Multi-Clutch Technology, and those clutches are the sole executors of gear changes. In the Manual mode, the gearbox managed to shift gears in just 100 milliseconds. That is incredibly fast, but the unit also had a comfort mode for day-to-day driving, as well as two sport modes. The first of them was 20% swifter than the Comfort mode, and the second Sport mode was 20% prompter than the previous. Meanwhile, the Manual mode is an extra 10% quicker than the S+ mode, which was the most rapid automated operating mode of that transmission. " https://www.autoevolution.com/news/m...ms-112461.html

all i could find below from Mercedes about the trans options....................

AMG SPEEDSHIFT MCT 7-speed sports transmission for personal set-up
Maximum individuality and customised dynamics – these are the special strengths of the AMG SPEEDSHIFT MCT 7-speed sports transmission. The four modes – "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport plus) and "M" (Manual) - offer the driver a personal set-up. In "C" mode, the ECO start/stop function is active and switches off the eight-cylinder engine when the vehicle is at a standstill. In addition, the transmission characteristics are tangibly soft, with smooth and early gear changes. Second gear is generally used as the starting gear in this mode.
The engine and transmission are far more agile in "S", "S+" and "M" mode; in addition, the ECO start/stop function is deactivated. Partial suppression of the cylinders proves perfect for an emphatic driving style: briefly and precisely interrupting ignition and injection under full load leads to even faster gearshifts with a more emotional sound than before. An automatic double-declutching function for downshifting and the RACE START function are also included as standard with the AMG SPEEDSHIFT MCT 7-speed sports transmission.

 

 

 

Peter - how does the sprintbooster feel in S+ mode? A little too jumpy/jerky with the throttle? Might just go ahead and get one of those as I had one in my C32 and the throttle responsiveness felt better.
