Infiniti caused quite a bit of hullabaloo late last year when it announced it would be changing its vehicle names so that all of its cars start with Q and all of its crossovers and SUVs start with QX (not the ones on the number plates seen locally).

Now, the luxury division of Nissan has posted a video that explains the historically relevant reason for the new Q badge.

Well, Infiniti is returning to the Q name to pay homage to its very first model, the Q45, and it's starting with the all new Q50 sedan.

Now, 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).
