engine harshness at high revs

IMO, what's half-assed is Nissan's insistence to continually update the VQ rather than completely redesign the engine. The fact that Nissan added VVEL and has stated they'll add DI soon to their V6 engine range indicates Nissan is never going to redesign this motor, leaving buyers stuck with a coarse V6 engine well into the next decade.

This is a major design flaw. Pretty idiotic for Nissan to run around touting how they built a legitimate Cayman competitor, somehow I doubt Cayman owners ever have to deal with any engine roughness. All I'm saying is Nissan could and should have done better, for $30k+ buyers shouldn't have this problem.

VVEL isn't a brand new technology, BMW's Valvetronic has been around for some time. And Toyota's Valvematic system came out the same time as VVEL.
