Touch Shift allows driver to manually downshift and allow upshifts by nudging the shift lever left or right from the Drive position.
Shift into Optimum Gear programming allows one-touch selection of the best gear for maximum acceleration or engine braking by holding the shift lever to the left of Drive for one second.
Driver-selectable Comfort mode starts vehicle moving in 2nd gear or a second Reverse gear, and upshifts at lower rpm, to help improve control on slippery surfaces.
AMG Speedshift™ AMG SpeedShift™ programming provides up to 35% faster gear changes, automatically downshifts during braking, prevents unwanted upshifting while cornering, offers one-touch selection of the best gear for maximum acceleration (Shift into Optimum Gear), and features torque converter lockup in all forward gears. Fingertip manual mode allows direct-access shifting through forward gears via the buttons on the back of the upper steering-wheel spokes (left button downshifts, right button upshifts) or via the Touch Shift feature of the shift lever, and will automatically intervene only to induce an upshift at redline, to downshift as needed upon full throttle, and to select 1st gear when the vehicle stops.
Three stages of sportier driving are available in the manual mode: Sport, SuperSport and Race.
Each stage changes the response, reaction and closing times of the automatic collision, shortening the shift processes. V In Standard and Comfort modes, the steering-wheel buttons operate the Touch Shift feature. Drive configuration Rear-wheel drive.
