By the mid-1990s, Infiniti was lagging behind Lexus and Acura in sales. The Q45 had retreated considerably from its focused, taut rendition of a sporty full-size luxury sedan, having become a barely recognizable, ponderously handling sedan that earned the nickname "The Japanese Lincoln". In the summer of 1998, Infiniti revived the G20, based on the JDM Nissan Primera, a compact sport sedan. The second generation G20 was marketed as a competitor to European entry-level luxury sport sedans, but it now weighed more than the first generation version. Because Infiniti continued to use the SR20DE four-cylinder engine and compact size, it fell short of sales expectations. The G20 was also marketed primarily to the wrong demographic, that being middle-aged professional women, and as such it was not as popular new as its main competition, the similarly priced Acura Integra.
