Infiniti has decided to abandon its current alphanumeric strategy for…an all-new alphanumeric strategy whereby passenger cars are given the “Q” designation, and crossovers and SUVs are dubbed the “QX”.

The G37, which has built up substantial equity over the last few years, will be renamed the “Q50″ for the sedan and “Q60″ for the coupe. The M will be re-named the “Q70″. On the light truck side, the EX will now be known as the “QX50″ all the way up to the Nissan Patrol-based QX, which is now the “QX80″, with the current JX and FX filling out the remaining slots.

The ascending numeric designations do help with creating a hierarchy based on vehicle size, and also takes engine size out of the equation – important if Infiniti ends up downsizing to smaller engines, a la the German marques.
