I've seen more than one person say that the Saturn Vue has Isuzu blood pumping through its veins. Obviously it is a GM product, but the GM and Isuzu collaboration is over, and just because the Vue has a 3.5L V6 doesn't make it the Isuzu 3.5L. It would have been the Isuzu engine if Isuzu were not pulling out of its partnership with GM, but given the current state of affairs, GM went to Honda for the Vue engine.
