This is a quote from Nissan’s specs for the current Sentra SE-R Spec V: “6-speed close-ratio manual transmission with dual-mass flywheel.” Ok, so I am interested in buying one of these top dollar Sentras, but would like to know what a “dual mass” flywheel is. The Spec V is the only Sentra with it. Thanks!
One of the biggest advantages to a dual-mass flywheel is the ability to lower the engine’s NVH (noise, vibration, harshness) levels inside the cabin. You can read far more detailed information here, if so inclined. For applications that need it, the technology is sound and proven after decades of use.
Back to the Sentra: considering the Spec V revs like a mother (6600 revs to make peak power) with those 200 horses, having a dual-mass unit ain’t a bad idea for a chubby street car that’s a far cry from it’s sport compact origins dating back to the early 1990s. Then again, what modern car isn’t bigger than its britches?
Bonus! A Piston Slap Nugget of Wisdom:
Sticking with the SE-R Ain’t What It Used To Be theme: it’s ironic that the only manual cog swappers in the lineup are the super-strippo Sentra, or the top dollar SE-R Spec V. Everything in between has the fun-sucking CVT. Even the SE-R, albeit with paddle shifters that must help with…something!
Perhaps Nissan should take a page from their marketing tagline, do us all a favor and “Shift The Way They Move?”
