The BMW E89 is the second generation of the BMW Z4 range of two-door roadsters, and was produced from 2009 to 2016. The E89 replaced the E85/E86 Z4 and is the fourth model in the BMW Z Series.
The E89 Z4 was the first Z Series model to use a retractable hardtop roof, and meant there were no longer separate roadster and coupé versions of the car.
There was no Z4 M model for the E89 generation.

Development and launch
The E89 was the first BMW to be designed by two female designers - Juliane Blasi (exterior) and Nadya Arnaout (interior) in 2006.
The BMW E89 Z4 was officially announced on 13 December 2008 and was unveiled at the 2009 North American International Auto Show in Detroit, alongside the MINI Convertible. The BMW E89 Z4 was then launched in markets on May 2009.
A total of EUR130 million was spent from 2007-2009 in expanding the Regensburg plant for production of the BMW E89 Z4. Although its E85/E86 predecessor was produced in the Spartanburg plant in the United States, the E89 was produced in the BMW's Regensburg plant alongside the E93 3 Series convertible.

Concept cars
Zagato Coupé (2012)
The Zagato Coupé was a concept car based on the E89 Z4 made in collaboration with Zagato, and was unveiled at the Concorso d'Eleganza Villa d'Este on 25 May 2012. As Adrian van Hooydonk and Zagato chief designer Norihiko Harada were friends, the decision was quickly made when Andrea Zagato proposed a collaboration with BMW. The body of the Zagato Coupé was built entirely by hand and includes a double-bubble roof, 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 matt "z" letters, with "z" letters embroidered into the seats.
Zagato Roadster (2012)
The Zagato Roadster was the roadster version of the Zagato Coupé that was unveiled three months earlier, and was introduced at the Pebble Beach Concours d'Elegance on 19 August 2012. The Zagato Roadster was created in six weeks, from the first design idea to the finished model. Similar to the Zagato Coupé, the paint colour of the Roadster changes appearance according to the lighting, ranging from dark grey to a light silver. The tonneau cover also incorporates a double-bubble shape, and features a black interior, with a strip of brown leather trim extending to the roll-over hoops.
