The Traverse and the Acadia are two medium sized crossovers built by GM which were, up until recently, nearly identical. However, the Acadia has been heavily revised with an all new model and the Traverse was left behind. Why? Well, because the 2018 Chevrolet Traverse is still under development and it is expected to be released sometime in 2017. Before the two cars were pretty much identical but things are going to change from now on. The Acadia uses a shorter platform than before by around seven inches. On the other hand, the Traverse will still be just as big as before but it will still benefit from the massive weight savings of the new platform.
