The letter Q goes again to the start of Infiniti within the late Nineteen Eighties. The very first automotive they ever produced was the Q45 full-size sedan. The 45 within the title indicated that the automotive featured a 4.5 L V8 engine. Before the common Q change, the numbers at all times indicated the engine measurement, such because the G37 having a 3.7 L engine. As for the letters, they decided which sort of automotive it was. Gs have been compact vehicles, EXs and FXs have been crossover SUVs, and Ms have been mid-size sedans. If a automotive had an X within the title, that signaled that it was a bigger automobile.

Then, the 2013 title change occurred, throwing almost each naming conference out of the window. The just one that remained was the usage of the X, the place a Q would point out a sedan and a QX would indicate an SUV. Once Infiniti introduced within the legacy letter, the numbers not correlated to the engines. Instead, they have been to sign the evolution of the automotive. The Q50 was the following step after the unique Q45.

50 is now the bottom degree for the place Infiniti autos begin. You have the QX50, adopted by the 55, 60, and 80. Vehicles just like the Q60 and QX70 have been discontinued, which accounts for the quantity gaps within the names. Switching their names totally to this scheme simplifies and standardizes the whole lot. You simply need to preserve the numbers straight.
