The first generation of BMW Z4 was introduced for the 2003 model year. This new sports car was initially available as a roadster (E85) and then later as a coupe (E86). The Z4 was offered with either an inline 4 engine, or a trio of inline 6 engines. The top of the line variants for the E85/E86 were the Z4 M Roadster and Z4 M Coupe, but other variants include the 2.0i, 2.2i, 2.5i, 2.5Si, 3.0i, and 3.0Si. Built until 2008, the E85/E86 was replaced by the E89 for the 2009 model year.
