TheBMW Z4 (E89) is the second generation of theBMW Z4 range of two-doorroadsters, and was produced from 2009 to 2016. The E89 replaced theE85/E86 Z4 and is the fourth model in theBMW Z Series.
The E89 Z4 was the first Z Series model to use aretractable hardtop roof, which meant that there were no longer separate roadster and coupé versions of the car.[2] There was noZ4 M model for the E89 generation.[3]
The Z4 (E89) was succeeded by theZ4 (G29) in 2018.[4]
The E89 was the first BMW automobile to be completely designed by two female designers — Juliane Blasi (exterior) and Nadya Arnaout (interior) — in 2006.[5][6][7][8][9]
The Z4 (E89) was officially announced on 13 December 2008[10][11][12] and was unveiled at the2009 North American International Auto Show in Detroit, alongside theMINI Convertible.[13][14] The Z4 (E89) was then launched in markets in May 2009.
A total of €130 million was spent from 2007 to 2009 in expansion of theRegensburg plant for production of the Z4 (E89).[15] Although its predecessor was produced in theSpartanburg plant in the United States, the E89 was produced in the BMW's Regensburg plant alongside theE93 3 Series convertible making it the third Z series car to be manufactured in Germany since theZ1 andZ8.[16][17]

The Zagato Coupé was a concept car based on the Z4 (E89) developed in collaboration with Italian design houseZagato. It was unveiled at theConcorso d'Eleganza Villa d'Este on 25 May 2012. As the then BMW chief designerAdrian van Hooydonk and Zagato chief designer Norihiko Harada were friends, the decision was quickly made when Andrea Zagato proposed a collaboration with BMW.[43] The body of the Zagato Coupé was built entirely by hand and includes a double-bubble roof[44] and Rosso Vivace paint which changes colour depending on the lighting, ranging from a near black to a bright red. The Zagato Coupé also incorporates the letter "z" in its design, with the kidney grille composed of small matte "z" letters,[45] with "z" letters embroidered into the seats.[46]
The Zagato Roadster was the roadster version of the Zagato Coupé that was unveiled three months earlier, and was introduced at thePebble Beach Concours d'Elegance on 19 August 2012. The Zagato Roadster was manufactured in six weeks, from the first design idea to the finished model.[47] Similar to the Zagato Coupé, the paint work of the Roadster changes appearance according to the lighting, ranging from dark grey to a light silver. The roadster does away with the retractable hard-top of the Z4 and incorporated atonneau cover for protection of the interior which incorporates a double-bubble shape.[48] The Zagato roadster has a black interior, with a strip of brown leather trim extending to theroll-over hoops.[49]
