Rev-matching is vital during downshifting to make even the harshest charging sports car shift smoothly. On the Nissan 370Z, the optional SynchroRev Match automatically blips the throttle between downshifts, which matches engine and transmission speed. The results are smooth downshifts and happy, whiplash-free passengers.
When the feature is activated via S-mode button, the 370Z will rev the engine with no input from your right foot as soon as your hand moves the gear selector into a lower numeric gear. The gear you choose and vehicle speed will determine the rpm jump. Carefully engage the clutch and the reward is a buttery smooth engagement. It takes a little getting used to, but once the 370Z revved the engine and matched gear changes perfectly and consistently every time, I found it second nature to let the feature do its job.
