Yup ... difference.

Green Mode: Why Did they include this?
Regular Mode: 80% of my driving
Sport Transmission: holds RPMs on lift of accelerator and allows higher RPM at each gear, great for maintaining speed in cornering.
Sport Mode: Stiffer steering, burble and pop on lifting accelerator.

I wish putting in Sport Transmission just did the last two. Oh, well, fun to learn the oddities of the car.

Has anyone put a table together or seen showing speeds like 0-60 for each compared across models and years?

 

And the DDC won't stiffen the suspension if you only have the transmission in S. Sure does drive better if the transmission is in a more responsive gear.

 

It changes the throttle response on my '14 F56.
