It is an aluminum open deck block design with microfinished internals and relatively light weight. While the VQ is an award winning engine, its predecessor, the VE30DE, is regarded as a superior powerplant. Unfortunately, Nissan fell on hard financial times and could no longer afford to produce the expensive VE. Instead, they turned to the VQ as a cost cutting measure.
