Infiniti would start 2015 by renaming the last of its cars that hosted names from prior years. The Q40 was introduced, replacing the G37, following a one-year pause in production. It would be essentially the same car with fewer options. The Q70 got a new long wheelbase edition that offered more interior room and a fresh front end, with new features and options. Last on the list was the QX60, which got CVT programming to improve shifting.
