Currently have a 2011 G37 with the VQ37HR....not as quiet or quite as smooth as the VQ30, but a naturally aspirated V6 getting 330HP? They did something right. The variable timing and lift setup is complex but seems to be pretty reliable, especially considering every cylinder has its own stepper motor (which leads to some of the ticking noises its known for). It gets a little vibrat-ey above 5500 RPM or so but if Im pulling that many RPMs Im more concerned with not running into things.
Had a 2001 Frontier with the VG series engine. Completely underpowered, and you mentioned complex....you should see the maze of coolant hoses/tubes on the underside of the intake plenum. But that engine is bulletproof. Sold that truck to family member too, has 84K miles on it and its done things it probably never had any business being asked to do. Only thing done to the engine was timing belt service.
I do not understand why it is problem to get 330hp from naturally aspirated V6?
BMW was pulling 321hp out of 3.2ltr some 23-24 years ago, though it was inline engine, but that is not the point.
The G was Nissan/Infiniti's attempt to go at the 3 series and succeeded at least for a bit. The VQ engines were getting 300 ish HP in 2007. I know its not "ancient" like the BMWs were, but it was good for Nissan at least. Of all the Nissan and Infiniti's Ive owned, the only complaints I ever had were that they felt underpowered.
I admittedly have never owned (or even driven) a BMW mostly because I keep my stuff long enough that I could foresee high owning costs getting to me at some point. Im sure they are great vehicles but nowadays I keep reading how the newer/current Bimmers are more tame/luxury than driving experience oriented like they used to be. Kinda bummed that I missed out on the chance.
Nissan did succeed a bit, but it is not all in engine.
But I agree, VQ engines are IMO tru refreshment in Japanese manufacturers line up.
