The E90 automobile platform is the fifth and latest generation of BMW's 3 Series entry-level luxury car / compact executive car. It replaced the E46 sedan and touring models in 2005. The E90's dimensions are larger than its predecessor's in every aspect, and for the first time since the E21, the volume model 320i uses an Inline-4 engine. However, despite the change for the sedan and touring models, the current 3 series coupé, M3, and cabriolet variants are still based upon the E46.
