Yeah, that's the VQ35, it's not any bigger than the VG30 on the outside, but is lighter, more powerful and smoother. Either one is a tight fit in a B-car.

Typical V6 vibration is worse than inline four. Four-bangers have secondary unbalance as do 60 degree V6. 90-degree V6 have an annoying primary unbalance. The VGs are apparently 60 degree engines, but not smooth, at least the two I drove (in vibration). Maybe I got some bad ones.

VQ engines are 60 degrees and supposedly very smooth.

Many newer 90-degree V6 (Ford 3.8, GM 3800, etc) have balance shafts and are very smooth as a result. Even Porsche licenses the Mitsubishi balance shaft technology.
