Infiniti announced its plans to introduce a new nomenclature strategy that will be applied from the model year 2014.
Each model in Infiniti's lineup will adopt a letter and a number designation based on the body and the vehicle's position in the lineup. The sedan and convertible models will use the Q prefix, while the SUVs will get QX.
As a consequence, starting with 2014MY the M sedan will be known as the Q70, while the G coupe and convertible models get the Q60 name. Infiniti will use the Q50 designation for the upcoming G sedan that will probably be unveiled in Detroit next month.
This name change will affect the entire lineup so the EX will be renamed QX50, while the FX will be sold as the QX70. In addition, Infiniti will sell the JX as the QX60 and the QX as the QX80.
