The BMW E89 Z4 is the chassis code of the current second generation BMW Z4. Unlike its predecessor, the BMW E89 Z4 features an automatic retractable hardtop convertible roof like the Mercedes SLK, and can be raised and lowered in under 19 seconds. Since the BMW E89 Z4 had a retractable hardtop, there are no longer separate roadster and coupé versions of the car. The BMW E89 Z4 is the first BMW to be designed by two female designers - Juliane Blasi (exterior) and Nadya Arnaout (interior) in 2006.
A total of €130 million was spent from 2007-2009 in expanding the plant for production of the BMW E89 Z4. Unlike its predecessor (the BMW E85 Z4), the BMW E89 Z4 is produced in the Regensburg plant, and not in Greer, South Carolina. The BMW X3 took its place, which made the Spartanburg plant the main production centre for the BMW X family. Production of the BMW E85 Z4 was discontinued in mid-2008, and the BMW E89 Z4 was produced from February, 2009 onwards.
The BMW E89 Z4 was officially announced on 13 December 2008 and was unveiled in 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. The Life Cycle Impulse for the BMW E89 Z4 was implemented on all models on March 2013.
The BMW E89 Z4 was unveiled to the public in 2009 in the North American International Auto Show alongside the MINI Convertible. Early BMW E89 Z4 models included the sDrive 23i, sDrive 30i and the sDrive 35i. The sDrive 23i and sDrive 30i models then ceased production in 2011, and were replaced by the sDrive 20i and sDrive 28i. A sDrive 35is model was introduced in 2010, and is a more powerful model to the sDrive 35i and featured an overboost feature. In March 2013 (in the Life Cycle Impulse), the sDrive 18i model was introduced to the Z4 lineup.
An FIA GT3-specification car was available to private teams. While the production version of the BMW Z4 has a six-cylinder engine, the GT3 car is powered by a 4.4-litre eight-cylinder engine derived from the BMW M3 GTS, which produces approx. 515 PS (379 kW; 508 bhp). The weight of the BMW Z4 GT3 is approx. 1,190 kilograms (2,624 lb).
This was a concept vehicle commemorating 75th anniversary of BMW 328. It included exterior and interior parts made of carbon fibre reinforced plastic (CFRP); leather, matt and high-gloss black polished aluminium as well as the CFRP interior; asymmetrically designed windscreen with a recess in the middle, four wide leather straps run across the bonnet, two-part light alloy wheels with black aluminium rim and black chrome butterfly nut bearing the BMW emblem.
