And the gear will stay active in Drive mode if you are not using your gas pedal. ie Engine braking coming down a long hill.You can move the shift lever from Drive to Sport while the car is moving without a problem. There is nothing in the owner's manual that prohibits that. You can also use the paddle shifters in either D or S. When in D the paddle shifter will automatically put you into the Sport mode and display the gear you have selected in the speedometer. If you don't shift up or down in D with the paddles, then the transmission automatically goes back into the Drive mode. You can use the paddle shifters without lifting your foot off the accelerator.
