Final answer:
The 2022 Maxima's Downshift Rev Matching in manual shift mode will match engine RPM to ensure a smooth gear change by automatically adjusting the engine speed during downshifting.
Step-by-step explanation:
When downshifting in manual shift mode, the 2022 Maxima's Downshift Rev Matching will match engine RPM for smooth gear change. Downshift Rev Matching, commonly known as rev-matching, is a feature used in performance cars with manual transmissions that automatically adjusts the engine speed to the correct RPM to match the next gear into which the vehicle is being shifted. This results in a smoother transition and less wear on the transmission. It doesn't merely increase or decrease engine RPM; instead, it modulates the RPM to ensure that the engine speed is synchronized with the wheel speed for the specific gear selected.
