"Understanding Auto Rev-Match Technology"

Auto rev-match technology automates the process of rev matching during downshifts in manual-transmission cars, smoothing out the process and reducing clutch wear over time. Nissan introduced this technology in 2009, and it has since been adopted by other automakers. The system relies on various sensors and the engine's ECU to calculate and execute throttle blips for smooth downshifts, and it also works on upshifts to reduce clutch wear. While some argue that it takes away from the driver's engagement, aftermarket solutions are available for older vehicles, offering similar functionality at a more affordable price.
