The Infiniti QX65 is a new mid-size SUV model with a fastback shape, recently added to the brand's lineup. The QX65 is considered important for Infiniti's revival, as the brand seeks to reclaim its past success and turn around its fortunes, particularly in the US market. It will reportedly receive a V-6 upgrade in 2027, and its performance may impact the brand's efforts to reverse years of sales decline.
