The E90 is the currently available generation, which debuted for the 2006 model year, and is available as the sedan (E90), wagon (E91), coupe (E92), and coupe cabriolet (E93). It is completely re-engineered from the E46, including changes to engines, transmission, the passenger compartment, suspension technology, as well as a host of high-tech features and options. The coupé/cabriolet body is now its own design and no longer derived from the sedan minus two doors unlike its predecessors, being longer and narrower than its E90 counterpart. Major features include Comfort Access, bi-Xenon adaptive headlamps, Active Cruise Control, and Active Steering. The lineup received a mid-generational facelift for the 2009 model year.
The E90 series also marks another first for BMW—a retractable hardtop convertible.
