BMW Z4 Roadster is an open double car and much more, replacing the roof Z3. Compared with its predecessor, Z4 slightly gained in all directions, but kept the general concept of this roof.
BMW Z4 received in the United States in October 2002 appeared in Europe in March 2003. Like his predecessor, the car is available in the United States at the factory in Spartanburg.
BMW Z4 easily combines the two. This is a classic roof at the same time emphasizes the Z4 sports of fast-bending bonnet, long wheelbase and low seat.
Protuberant and curves and surfaces make splendid play of light and shadow. Strong lines are interspersed with gentle curves. Ideal flat steel surface and excellent skin significantly enrich every detail. It appears from BMW Z4 is thallium. Its form "saying" the door behind which the body like expanding.
Notch on the door of the top limited clear from the brink of the lap, and the bottom - just as sharply defined "rib stiffness" high threshold.
Completing the picture slashes, boldly held upwards from the front wheels to the frame of the front windshield. Character lining sink BMW surrounded by radiant chrome and double Xenon headlamps (option), with integrated fog lamps, attached Z4 elegant and unflagging form. Here are just a heavy chuck looks strange, if not from the opera. The standard Z4 2.5i invited elegant curtain fabric with mechanical actuation.
The analogy with "Seven" is the Z4 interior. Nothing in common with the original "driving" the panel deployed console to the driver. This concept interior, which in the 1970s came to BMW genius Paul Marriage, in Munich cultivated for decades. All the necessary information you have in front of you with appliances. Rudder, a small, unemployed, with a leather collar and incredibly stylish iron spokes. Micro design in BMW Z4 at the height developed every detail, whether protective arc of chairs, hand handcuffed or door panels, "crossed" special "twisted" pens.
Particularly good indoor sports version of "metal" finish. "Sports" seats for the driver and passenger are standard on the Z4. Black leather "Oregon" (it) will make your impressions of the trip even more attractive. In some versions Comfort warmth only a box of wood, substitute silver plastic panels with aluminum.
The advantage of the new body for the owner roof is a relatively large trunk (up to 260 litres) of convertible bay for the curtain, which is sufficient for carrying two large bags. The curtain of fabric is Z-manner and equipped with heated rear windows.
Additional options include Hi-Fi audio amplifier with a low frequency technology Carver, as well as a special phone. The standard kit includes a new Z4 sports leather steering wheel type, system protection, and if the bus to get to their own coding, with piercing.
High-octane mixture impeccable quality and the most modern technology is at the heart of the engine BMW Z4 which was made of a special lightweight alloy. Thanks to a unique combination of Double Vanes, to regulate valves best way, a special module intake air and 4-valve technology BMW achieved the highest torque and lightning reactions. The revitalization of the "Sport" option proposed as a system of dynamic traffic management Driving Dynamic Control to remove the engine to even higher levels. Models collected Z4 3.0i engine (170 kW / 231 hp / maximum speed of 250 km / h) and Z4 2.5i (141 kW / 192 hp / 235 km / h). The Z4 3.0i 6-step a mechanical gearbox and a five-for Z4 2.5i model, or a five-speed automatic transmission (as a set of additional equipment).
Thanks to the wide track, low center of gravity, optimum weight distribution between the axles in a ratio of 50:50, and the precise steering control system (Electric Power Steering) BMW Z4 provides a good dynamic and manageability. In addition, high-endurance brakes and the dynamic stability control Dynamic Stability Control (DSC III), with the possibility of including traction control regime guarantee maximum safety in all situations.
The Z4 for the first time in history, and car smuggle BMW usual hydraulic steering replaced by power assistance. This scheme was much simpler. Power assistance consumes power only when turning the steering wheel, his work is easy to administer, in accordance with the speed or the level of lateral acceleration. However, if the engineers behind BMW and ZF firm, which has traditionally supplied Bavarian steering mechanisms-decade experience of the booster rocket configuration, with electro motors all have to understand anew. Z4 version Sport extremely sensitive to the slightest turns driving. A click of "sport" to the left of the console tool box is changing not only features an electronic pedal, but the algorithm of electric power.
The "sport" to drive better, but not much. Efforts to drive higher, but "transparency" anyway. Reactions spot, but not exact, correct trajectory in the high-speed turns is fast pulse movements. But in turns BMW Z4 no slower than Speedster. First, the power unit is fully justifies this definition: it is indeed power. Drive "at the grass roots" strong, and after 3000 rpm pushing the gas pedal is instantly reactive impulse to any transfer. Chassis here that neither talk, the great. Tyres evil grip clinging to the asphalt, geometry trimmings can easily follow the roof at the wheel. Gradually accustomed to the reaction machine, and how annoying that the need to stop turning left knee in the door handle.
The stabilization DSC prevent slipping unobtrusively, but the authority and confidence. Against all canons auto sports at BMW Z4 can boldly press on the gas or brake in turn, the computer instantly removes excess power or recalculates the balance of braking force at each wheel. The single click of a button does not disable DSC stabilization system, as usual, a trigger-DTC Dynamic Traction Control. As told Bavarian, it is compensated for the lack of Z4 self-locking differential activation DTC admitted to some "controlled" unwanted steering wheel. However, with the development of skidding
The Sport version is very hard suspension. Sound row "Six fills saloon-even open, with the folded roof. Whether the voice is a little louder engine could call it gimmicky ... Travel to "comfortable" version is more pleasant emotions. At 16-inch wheels instead 17-inch without buttons "sport". At turns driving Butler reacts calmer exhaust sound is not as aggressive, suspension noticeably softer "swallows" irregularities.
The flaws in habits "sports" Butler is due in large part to the other wheels. For example, the longitudinal wave asphalt drive with a "sport" suspension starts from further tilt-so it is, when the wheels of a departure from the so-called modified shoulder running wheel. A "comfortable" at the same roof slope calmly rode directly, not in response to the alignment. A BMW Z4 3.0i Comfort hardly slower "sports" version.
In fact, despite the fast sliding steering mechanism with a very low gear for (14.2), driven by Z4 from lock to lock commits more than three revolutions. In this way, the front wheels are turning at very high angle. Diameter turn, respectively, the roof is less than ten metres - the-maneuver!
