The current Nissan line-up depends on four sedans serving a specific driving consumer market. The Nissan Versa sedan delivers 30-plus miles per gallon fuel economy. An economical compact with some refinement, the Sentra has proven to be a respectable performer with the occasional presence of the SE-R Spec V model. The Altima is targeted as the family-focused four-door in the Nissan product line. The premium flagship for Nissan since the 1980s, the Maxima is routinely the leader for the brand's sedan styling and engine power. On all Nissan sedans, some additional performance attitude is offered with the SR trim level such as a sport-tuned suspension and sharper bodywork.
