# BMW Z4 (E89)

The BMW Z4 (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, which meant that there were no longer separate roadster and coupé versions of the car. There was no Z4 M model for the E89 generation.
The Z4 (E89) was succeeded by the Z4 (G29) in 2018.

## Development and launch

The E89 was the first BMW automobile to be completely designed by two female designers — Juliane Blasi (exterior) and Nadya Arnaout (interior) — in 2006.
The Z4 (E89) 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 Z4 (E89) was then launched in markets in May 2009.
A total of €130 million was spent from 2007 to 2009 in expansion of the Regensburg plant for production of the Z4 (E89). Although its 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 making it the third Z series car to be manufactured in Germany since the Z1 and Z8.

## Design

The E89 Z4 was offered with the base level sDrive or optional M Sport trim. The M Sport trim included 18-inch alloy wheels, leather upholstery, sports seats, redesigned front and rear bumpers, sports steering wheel and sports suspension. An optional Design Pure Impulse package was also offered, having colour matching Alcantara or Nappa leather, and BMW Individual anthracite roof lining.
The 2013 facelift also introduced the Design Pure Traction and Pure Fusion Design package, which had the choice of the exclusive Valencia Orange and Sparkling Brown metallic paintwork respectively (alongside regular colours), and colour matching interior design elements. The Design Pure Traction package also featured a black hardtop roof.

## Equipment

The E89 Z4 came standard with BMW EfficientDynamics technologies, such as regenerative braking and electric power steering. Models also feature an electric parking brake, engine start-stop system, directional headlights, and a driving mode selector with Comfort, Sport, and Sport+ modes which adjust throttle and gearbox behaviour, power steering weighting, and the adjustable dampers (with the optional 'Electronic Damper Control'). The models could also be ordered with the iDrive infotainment system with BMWConnected services and keyless entry.

### Z4 sDrive35is

The engine has a computer-controlled overboost function for 3rd to 7th gears. The boost function activates after each gear change with full throttle, and lasts for 7 seconds between 1,500 and 4,500rpm. Peak torque during overboost is 500 N⋅m (369 lb⋅ft), compared to 450 N⋅m (332 lb⋅ft) without.

## Concept cars
### Zagato Coupé (2012)

The Zagato Coupé was a concept car based on the Z4 (E89) developed in collaboration with Italian design house Zagato. It was unveiled at the Concorso d'Eleganza Villa d'Este on 25 May 2012. As the then BMW chief designer 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 matte "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 manufactured in six weeks, from the first design idea to the finished model. 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 a tonneau cover for protection of the interior which incorporates a double-bubble shape. The Zagato roadster has a black interior, with a strip of brown leather trim extending to the roll-over hoops.
