New Car Quick Quote
When Nissan’s luxury division first emerged in the 1990 model year, the lineup included a big Q45 sedan and an M30 coupe. By 1993, the M30 was gone; but a decade later, the “M” prefix returned on an M34 sedan. INFINITI revised its model-name pattern for 2014, adopting a “Q” prefix for all passenger cars. The two-digit numerical suffix denoted that model’s position in the lineup. Thus, without changing significantly, the M37 and M56 sedans turned into a pair of range-topping Q70 models, powered by either a V6 or V8 engine.
