I have a 6MT and the whole car vibrates and almost feels like its going to rip apart at any moment lol (slight exageration) at high rpms. You really do feel it in the floor, steerng wheel, shifter...even the seat to some extent. Our car is very rough at high RPM's...I've been in a few cars that should be rougher per se, but are smooth as silk compared to this. Nissan lost points in the refinement department with this engine... everything, its gotta a very coarse feeling to it. Everything vibrates and sounds like its not supposed to be revving that high. Its something I've learned to live with, but it should not be this way. I wonder if its an engine mounts thing.... A similar ammount of vibration is transmitted back through the steering, pedals and shifter, but for me, it's mostly the noise. A lot of reviews I've read concerning the VQ engine say the same thing. It's not isolated to our car, it's the VQ in general. It is rougher than other engines and I would love for it to be smoother but you do get used to it. Likely this has to more to do with the natural imbalance of the V6, which has been exacerbated as they stroked the original VQ engine design more and more. Another engine recently revised with a longer stroke and VVEL is the VK50DE. How harsh is the VK50 in the FX50 at high rpms? Edit: After finding Edmunds review, they stated that the VK50, 'much like VQ35/37 this V8 isn't quiet or smooth @ high RPM.' So we can rule that it's either the longer stroke, the VVEL or both.
non vorrei però che fosse una..su quante? può avere un problema la sua,non credo che tutte vibrino come Mulinex... la Infinity coupè che ha lo stesso motore non mi pare abbia questi problemi. cerco in giro.. Cmq io ho avuto svariati V6..Alfa, Mercedes etc..ma nessuno ha mai avuto una sola vibrazione o sussulto...MAI
