The video explains that the Q name comes from Infiniti's very first model, the Q45. Infiniti is returning to the Q name to pay homage to that legacy, and it's starting with the all-new Q50 sedan. However, while most of Infiniti's 2014 models will get the new Q badge, the G37 Sedan will keep its nameplate through model year 2015 (despite the fact that Infiniti already changed the G37 Coupe and G37 Convertible models to the name Q60).
Confused yet? Watch the video below and let us know what you think about Infiniti's reasoning for changing its vehicle names.
