The Infiniti G Series Sedan is a lineup of executive sedans produced from 1991-1996, and again from 1999 to present. The early generations of the G Sedan were based on the Nissan Primera whereas the more recent models use a combination of performance and luxury features from the Nissan family. As of 2014, the G sedan moved to the new naming convention under the "Q" family. These are great sedans built for luxury and performance. Be sure to test drive the G sedans and get a feel for what they are all about.
