In mid-2013 Infiniti announced their Q30 Concept car would get its world premiere at the 2013 Frankfurt Motor Show, a move which would see Infiniti start an aggressive strategy to extend the Infiniti brand into new premium segments. In 2013, Infiniti's model designation changed to the coupes and sedans starting with the letter Q (SUVs and crossovers starting with the letters QX) and a number reflecting the model's place in the brand lineup. The M sedan became the Q70 while the G sedan was replaced with the Q50; meanwhile, the QX56 became the QX80 while the EX became the QX50.
