Synchrorev Match Transmission


This past year Nissan has released the 370Z to continue on the famed heritage of the past Z series automobiles. Along with a redesigned exterior, technically advanced interior, wider wheel base, and a bit more power, comes a very unique technical achievement. The newest Z, like past Zs, has the option of being purchased with a sports package which gives you the usual stiffer suspension, bigger wheels, and spoiler. However, there is one more added option that comes with the sport package that hasn't been seen on any past Zs, or any other vehicle for that matter; that is Nissan's new Synchrorev Match Transmission (SRM).


The new SRM system does exactly what it sounds like and matches your rpms to the proper power range when downshifting. For those who are unfamiliar allow me to explain; when downshifting in a manual car it is best to "blip" (apply a small amount of power) the throttle in order to make the shift smoother. People who are accustomed to driving manual cars know that finding the perfect rpm while downshifting isn't as easy as it sounds. The SRM transmission in the new Z does all the work for you; all you need to worry about is using the clutch and actually moving the shifter, all the rpms are matched perfectly when moving down through the gears. Not only does the SRM transmission help to smooth out your downshifts but it also helps quicken upshifting. It uses the same technique as it does down shifting by holding the rpms up higher in range so no power is lost when banging through the gears.

Now this advancement in technology surely helps the common driver with everyday upshifting and downshifting and its proven itself on the track, however, some enthusiasts still don't buy into it. Many "drivers" say that the SRM transmission takes away some of the overall skill in being able to drive a stick. They also state that half the fun of driving a stick is having complete control of the vehicles power when moving up or down through gears and when braking in hard corners. Nissan's answer to these individuals can be found in any of the 370Zs that lack the sport package but this is to say that you will be missing out on the stellar 19 inch RAYS wheels, Bilstein suspension, and deck spoiler. my best guess is that the SRM transmissions will be standard throughout Nissan's lineup or at least be an available option. All in all, the SRM transmission is a fantastic innovation in automobile technology and will surely be sought out by other car manufacturers; but for now, Nissan holds the key to an aggressive yet smooth shifting ride.
