Stars in the Euro NCAP - Crash Test

The BMW Z4 (internal: E85 - Roadster, E86 - Coupé) is a passenger car from the German car manufacturer BMW . The design of the Z4 was created under BMW chief designer Chris Bangle . The BMW Z4 was manufactured by the BMW US Manufacturing Company in Greer (South Carolina) .

Model history

The Z4, with the official trade fair presentation at the Mondial de l'Automobile 2002, came onto the American market in October 2002 and was introduced in Germany in March 2003. Because it is larger and more comfortable than the previously produced Z3 , it was called the Z4.

The convertible top was given a rear window made of glass, which can also be heated.

To limit the weight increase, high-strength steels were used for the body and aluminum for the hood. In addition, BMW used an electrically assisted power steering system for the first time, which only requires energy during the steering process and thus saves fuel.

In terms of chassis technology, the front axle corresponds to that of the Z3 with MacPherson struts , the rear axle is a multi-link construction .

The Z4 was available from € 29,900.
After initially great sales success, sales of the Z4 collapsed noticeably from 2004, which is why BMW decided to undertake an extensive model upgrade including the offer of a coupé variant.

Facelift

The revised version of the Z4 was presented to the public in spring 2006. Changes were made to both the interior and exterior design. The external, visual changes primarily concerned changed bumpers or aprons, new headlights and taillights with LED elements, revised rims and new colors. The interior has been upgraded with chrome applications, such as B. on the air conditioning controls, and expanded with new equipment packages. Technical innovations were u. a. also an electronic oil level control and a hill start aid .

The most important changes, however, concerned the chassis and engine area. As part of the chassis revision, there were also new N52 six-cylinder engines. The original BMW M54 engines in the variants 2.2i (125 kW / 170 PS), 2.5i (141 kW / 192 PS) and 3.0i (170 kW / 231 PS) were replaced by the N52 engines in the 2.5i ( now 130 kW / 177 PS), 2.5si (160 kW / 218 PS) and 3.0si (195 kW / 265 PS) replaced. The four-cylinder 2.0i variant with an N46 engine and 110 kW (150 hp) introduced in May 2005 remained in the range even after the facelift. Furthermore, all models with a manual transmission now had six gears (previously only on the 2.0i and 3.0i).

The top of the range was the Z4 M. It had the 252 kW (343 hp) 3.2-liter six-cylinder engine that had been used in the BMW M3 (E46) to date . With this engine, it accelerated from 0 to 100 km / h in 5.0 s and was electronically limited to a top speed of 250 km / h, up to 275 km / h were possible for an extra charge. Visually, the Z4 M differed through modified aprons, a slightly contoured bonnet and an exhaust system with four tailpipes. A sequential transmission, as it was available for the other M models, was not available for the Z4 M.

BMW Z4 Coupé (E86)

There was also a strongly motorized coupé variant of the Z4 with a fixed roof and hatchback with a tailgate. At the 2005 International Motor Show , the Z4 Coupé (E86) was first presented as a study before it came onto the market in spring 2006 (presentation of the production model at the 2006 Geneva Motor Show ) in a slightly modified form with the revised roadster. The second Z4 (E89) as a roadster with a fixed sheet metal roof was, so to speak, the successor to both Z4, roadster E85 and Coupé E86.

  Engine Z4 M (Coupé)

The coupé was only available with two units: the 3.0si engine with 195 kW (265 hp) and as the Z4 M Coupé with the 3.2-liter six-cylinder engine (252 kW / 343 hp) from the M3 (E46).

BMW Z4 M Coupé works racing car

BMW built 12 GT3 racing cars of the Z4 M Coupé. The cars were powered by a 3.2 liter engine with 316 kW (430 hp). Hans-Joachim Stuck and Claudia Hürtgen competed in the VLN endurance championship Nürburgring . In the 2009 and 2010 seasons, 11 out of 16 races were class winners.

However, the VLN endurance championships in 2010 and 2011 were each won with a near-series three-liter coupé, as there were more participants in the V5 class and thus more points could be achieved.

successor

In mid-July 2008, BMW officially announced that it would end production of the current Z4 at the end of August 2008.

A total of 197,950 units were built, including 180,856 E85 (Roadster) and 17,094 E86 (Coupe).

In May 2009, the successor, the Z4 E89 , appeared as planned , this time for the first time with a metal folding roof and the basic engine variant of the 2.5-liter in-line six-cylinder with 150 kW (204 hp). There was no pure coupé or an M version.
