The vehicle was originally announced December 13, 2008.[2][3][4] The vehicle was unveiled in 2009 North American International Auto Show in Detroit.[5] This time a coupé-convertible with folding hardtop, the Z4 (E89) will be built in Regensburg alongside the (E93) 3-Series Cabrio, likely due to the U.S. plant needing more room for SUV production. It moved upmarket, dropping the small four-cylinder base engine. In late 2011 BMW reintroduced a 2.0 litre, 4-cylinder powerplant with twin-scroll turbo (N20 engine varient).
