The 6-series will go away at the end of this year with nothing to replace it for the 2011 model year. Today’s decadent 6er has lost whatever relevance it had, not to mention the platform on which it is based. With the automotive world trending toward lightness and economy—or to use BMW’s own vernacular, “efficient dynamics”—the 6 no longer fits. And even with its techno-overload interior and 500-hp V-10 M6 halo model, the 6-Series never achieved the icon status enjoyed by the first-generation 6-series, which BMW offered between 1977 and 1988. It will be a quiet death.
