Woodcliff Lake, NJ – December 13, 6:00PM EST 2008… Poised to lead its market segment once again, the 2009 BMW Z4 Roadster will make its North American debuts at the 2009 North American International Auto Show on January 11.

Return of a Classic

The classic roadster is back – more powerful and more stylish than ever before. It is the BMW Z4, the only car in its segment combining classic roadster proportions with a seating position moved close to the rear axle, rear-wheel drive, with a retractable hardtop. 

The new BMW Z4 offers all the driving pleasure of a BMW Roadster with particularly refined and stylish flair. Driving with the roof down, this two-seater offers a refreshingly intense experience of the sunshine and the wind rushing by – and driving with the hardtop closed it provides all the comfort of a sporting coupe in the premium segment. So through this diversity and wide range of qualities, the new BMW Z4 is the re-birth of the roadster.

The design of the new Z4 comes out through classic details interpreted in new, up-to-date style. This outstanding two-seater offers a unique combination of elegance, agility, and supreme comfort. The aluminum shells of the two-piece lightweight hardtop come to rest in the roof compartment, saving maximum space in the process. Even with the roof closed, the new Z4 retains the proportions typical of a genuine roadster.

To ensure driving pleasure, the new BMW Z4 is offered with two inline-6 engine displacing 3.0 liters: 300 hp in the BMW Z4 sDrive35i and 255 hp in the BMW Z4 sDrive30i ensure truly outstanding acceleration and response at all times.

Comprehensive use of BMW’s EfficientDynamics technologies serves to provide an unparalleled balance of driving pleasure and fuel efficiency. While both models are available with a manual six-speed gearbox, the Z4 sDrive35i is available also with a dual-clutch sport automatic transmission featuring seven gears. The six-speed sport automatic is available on the Z4 sDrive30i. Both sport automatic transmissions feature steering wheel-mounted paddle shifters.

Featuring Dynamic Drive Control as standard, the BMW Z4 enables the driver to choose between three drivetrain and suspension settings at the touch of a button.

Design: the modern look of a classic roadster.

The new BMW Z4 takes on the classic look of the roadster in modern, flowing lines. The car’s proportions are borne out by the long and low-slung engine compartment lid, short overhangs, the long wheelbase and large wheels as well as the low seating position near the rear axle. 

The front view features a large, upright BMW kidney grille, wide air intake and the dual round headlights, typical of the BMW brand. All surfaces and lines, including the character lines on the hood, strive towards an imaginary target point on the road ahead.

The side view is dominated by the dynamic flow of the car’s shoulder line connecting the front and rear wheel arches and accentuating the stretched, athletic look of the Roadster. The horizontal orientation of the car’s lines and surfaces at the rear, in turn, emphasizes the sheer width of the new BMW Z4. Further characteristics are the extra-large hood extending far over the wheel arches, the black A-pillars, the gills at the side with their integrated LED direction indicators, as well as the slender rear fixtures with three-dimensional LED-fed rows of light.

Stylish, sophisticated, and typical of a genuine roadster: the interior.

For harmonious unison of the exterior and interior so important in an open-air car, the shoulder line is reflected by the door panels with their unique configuration and flow from front to rear. 

The contoured surface to the left and right of the steering wheel incorporates the controls for the lights and air conditioning. These elements are available trimmed in Satin Silver matte, Brushed Aluminum, and Ash Grain Wood, the respective color and trim variant also being used on the center console and door handle.

The standard seats with integrated headrests on the BMW Z4 sDrive35i feature high-quality Kansas leather in a choice of three colors. A fourth choice, Ivory White Nappa leather, is also available as part of the Exclusive Ivory White Leather Package, which includes sport seats and Anthracite wood trim.

An Extended Leather option (Z4 sDrive35i only) adds leather on the upper section of the instrument panel, the doorsills, the sun visors in Black leather as well as the leather-finish door closing handles in upholstery color on the passenger’s side.

The entire range of paintwork colors available on the new BMW Z4 is made up of no less than nine color tones including Orion Silver metallic exclusive to the new Roadster.

A successful concept with a great tradition:  inline-6 engines in the BMW Roadster.

Elegant roadster lines, the BMW kidney grille, and a inline-6 engine form a combination that, in 1934, made the BMW 315/1 an unprecedented success both on the road and in motorsport. That combination has been retained to this day in the BMW Z4. 

The new Z4 is therefore being launched exclusively with inline-6 engines, a choice of two engines providing both power and performance. These unique engines exhibit refinement and fast-revving response typical of a BMW six-cylinder, offering an unparalleled balance of performance and fuel efficiency in the premium roadster segment thanks to the BMW EfficientDynamics engineering strategy. The individual versions of the new BMW Z4 come with on-demand management and control of the car’s accessory drives, a variable oil pump, intelligent lightweight technology, and optimized aerodynamics.

BMW Z4 sDrive35i: performance with efficiency thanks to Twin Turbo and High Precision Injection.

The most dynamic version of the new Z4 comes with the world’s first inline-6 engine to feature twin turbochargers, High Precision Injection, and an all-aluminum crankcase. 

The use of two turbochargers (each supplying three cylinders) ensures responsiveness never seen before on a turbocharged engine. The engine achieves peak torque of 300 lb-ft without the slightest delay, and maintains this high level of torque throughout a broad rev range from 1,400–5,000 rpm.

Maximum output of 300 hp comes at 5,800 rpm, and the BMW Z4 sDrive35i accelerates to 60 mph in just 5.1 seconds (optional seven-speed double clutch sport automatic transmission in 5.0 seconds). The acceleration continues all the way to an electronically-limited 130 mph (150 mph when equipped with the optional Sport Package).

High Precision Injection is a key element in the Z4’s efficient performance. Injecting fuel directly into the combustion chamber offers a cooling effect allowing a higher compression ratio and optimized combustion efficiency. This second generation of direct gasoline injection developed by BMW ensures significant benefits in fuel efficiency without restricting the dynamic qualities of the engine.

Comfort and sportiness in one: Dynamic Drive Control.

Dynamic Drive Control allows the driver of the new Z4 to choose the drive characteristics of the car. In addition to changing damper forces on the Adaptive M Suspension, DDC also conditions the responses of the gas pedal, the power steering, and the response thresholds of Dynamic Stability Control. And if the car is fitted with either sport automatic transmission, the adaptive gearshift logarithms are adjusted. 

The driver operates Dynamic Drive Control via a button on the center console next to the gear selector. By pressing the button, s/he is able to choose from the NORMAL, SPORT and SPORT+ modes, thus activating a pre-configured, perfectly balanced set-up. The SPORT mode, for example, offers more-direct steering behavior and a more-direct response to the gas pedal. The SPORT+ mode, in turn, serves additionally to activate the Dynamic Traction Control mode of DSC, intentionally allowing slight wheelspin and thus enabling the driver to take a bend in a controlled drift.

Extra space, more safety.

The new BMW Z4 is slightly larger outside than its predecessor, at the same time offering significantly more comfort in terms of space and a lot more loading space: BMW’s new Roadster is 5.8” longer, 0.4” wider, and 0.3” lower. Wheelbase has grown 0.1” to measure 98.3″.

Apart from all-round visibility, the interior offers greater headroom (+0.20″), extra shoulder room (+0.79″) and more elbow freedom (+1.69″). The door opening, increased in size by 1.02″, allows even more convenient access with the roof closed.

The extremely stiff bodyshell, lightweight construction and near 50/50 weight distribution enhance both the safety and agility of the new BMW Z4. High load-resistant subframes, optimum use of crush zones, the extremely stiff passenger cell and highly efficient restraint systems ensure outstanding accident safety. Frontal and head/thorax airbags, belt latch tensioners and belt force limiters are activated by the sensor-controlled electronic safety system as a function of the type and severity of a collision. The head/thorax airbags are integrated on the outside of the seat backrests and inflate over a large surface in the event of a collision from the side.

Making its premiere in the BMW Roadster:  the latest generation of iDrive.

The new Z4 is the first BMW Roadster to feature the iDrive control system as part of its optional navigation system. In the new Z4 the iDrive serves to activate all entertainment, information, navigation and telecommunication functions. 

The system itself is made up of a Controller on the center console and a folding, high-resolution Control Display on the instrument panel, allowing the driver to intuitively and safely mastermind all available functions.

Pressing the direct selection buttons on the newly configured Controller, the user is able to spontaneously change to the CD, radio, telephone and navigation functions. The range of direct selection buttons has now been rounded off by the three MENU, BACK and OPTION command buttons, and programmable favorite buttons in the instrument panel allow the user to save and directly select radio stations, telephone numbers and navigation destinations, and other menu items available directly through iDrive.

Measuring 8.8 inches in size, the high-resolution Control Display with its resolution of 1,280 x 480 pixels offers excellent clarity in presenting graphics or pages from the internet. A picture of the Controller shown in the Control Display gives the driver greater and clearer orientation in choosing the next step in the operating process.

Using the navigation system is even easier thanks to iDrive. Full-screen map presentation, for example, offers an incomparably detailed overview of the region in which the driver is currently traveling. As an alternative the Control Display also offers an assistance window presenting further highlights and maps independent of the main map.

With navigation data saved on an 80 GB hard disc installed in the car, access times are faster than before. And at the same time the hard disc may also be used as a 15 GB music archive.

Roadster-specific climate comfort and leather with Sun Reflective Technology.

The new BMW Z4 is equipped as standard with air conditioning and seven blower stages. Optional automatic climate control allows separate temperature selection on the driver’s and passenger’s side, individual, automatic temperature control in five stages of intensity, and manual adjustment of air stratification. With the roof open, automatic climate control includes convertible mode. 

Like BMW’s Convertibles, the leather in the new Roadster incorporates Sun Reflective Technology. A special, highly innovative type of leather on the seats, interior panels, and steering wheel that significantly reduces the heat effect of bright sunshine: Treatment of the leather in Sun Reflective Technology serves to integrate special color pigments into the material to reflect infrared radiation in the sunlight.

BMW Ultimate ServiceTM:  Providing owners with incredible value and peace of mind

The 2009 BMW Z4 Roadster will feature BMW Ultimate ServiceTM, a suite of services that includes the BMW Maintenance Program (formerly called Full Maintenance), Roadside Assistance and the New Vehicle Limited Warranty. BMW AssistTM with TeleService is part of the optional Premium Package or can be ordered separately as a stand-alone option.
