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
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.
Cycling in 20 seconds: the
The new BMW Z4 is the
first BMW roadster to protect its occupants from wind and weather
with a fully retractable hardtop. This two-piece lightweight
aluminum shell opens and closes at the touch of a button within 20
seconds. The compact packaging of the folding roof enables the Z4
Roadster to retain the characteristic, slender proportions of its
This innovative roof system offers outstanding acoustic and
aerodynamic qualities and sets a new standard in the Z4’s segment.
Large windows and the high-quality roof lining give the hardtop a
light look. Driver and passenger enjoy a bright ambience, generous
space, and optimum visibility. Compared with the former model, the
side windows are 40% larger, the see-through area in the rear window
52% larger, and all-round visibility increased14% over the previous
The glass rear window in the hardtop is equipped with an electric
defroster and the four side windows of the new BMW Z4 may be lowered
individually. The higher roofline and larger door openings allow
easier and more convenient access with the roof closed.
The retractable roof may be operated either by a switch in the
center console or by remote control key fob when equipped with
optional Comfort Access. Comfort Access also allows convenient
loading and unloading of the luggage compartment with the roof open.
To provide access to the luggage compartment in this case, the open
hardtop is moved to an interim position facilitating the removal of
Flexible storage with optional
The roof compartment and
the luggage compartment are separated from one another by a moveable
partition, which may be folded up to increase luggage space if the
roof will remain closed.
The moveable partition in the new BMW Z4 is unique in the premium
roadster segment, and offers enough luggage space with the hardtop
open for a medium-sized hard-shell suitcase.
Using the optional through-loading system to the passenger
compartment, the Z4 is able to accommodate a 46-inch full-size golf
bag. When the roof is closed the luggage compartment easily
accommodates up to four crates of large bottles or – when using the
through-loading system – two 46-inch golf bags.
Various other storage compartments are designed into the interior.
The new Z4 offers storage trays in the center console, a 10-liter
glove box, hinged compartments in the doors, and additional space
behind the seats.
Included with the Cold Weather Package is a storage package that
provides an even wider range of storage and loading functions, with
fastening nets on the rear panels of the seats and in the
passenger’s footwell, lashing belts in the luggage compartment, as
well as a storage box in the bulkhead leading to the luggage
Optional through-loading system together with a transport bag
ensures even greater versatility, allowing the user to load slender
items such as golf bags or two pairs of skis measuring up to 67" in
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
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
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

power and performance, excellent motoring refinement and outstanding
efficiency, the 6-cylinder naturally-aspirated engine in the BMW Z4
sDrive30i again offers the very best in its segment. Weighing just
355 lb thanks to its composite magnesium/aluminum crankcase,
cylinder head cover made of a special synthetic material and
lightweight camshafts with aluminum VANOS control unit, is
While BMW’s VALVETRONIC engine management controls valve stroke on
the intake valves, double-VANOS varies the angle of the intake and
outlet valves in an infinite process. This allows particularly
efficient use of fuel, providing a “beefy” torque curve and giving
the engine instant response.
The engine in the BMW Z4 sDrive30i develops maximum output of 255 hp
from 3.0 liters capacity at an engine speed of 6,600 rpm. Maximum
torque of 220 lb-ft, in turn, comes at just 2,600 rpm.
With this kind of power, the BMW Z4 sDrive30i accelerates from a
standstill to 60 mph in 5.6 seconds (with optional sport automatic
in 6.0 seconds). Top speed is electronically limited to 130 mph (150
mph when equipped with the optional Sport Package).
6-speed transmission with short
gearshift travel featured as standard.
All variants of the new
BMW Z4 come as standard with a 6-speed manual gearbox. Developed
specifically for BMW’s new Roadster, the various transmission
options are particularly sporting in their character. Indeed, this
is borne out in particular by extremely short gearshift travel much
shorter than on all other current BMW models with a manual
Optional: 7-speed sport automatic
with double clutch
and 6-speed sport automatic with paddle shifters.
As an option, the BMW Z4
sDrive35i is available with BMW’s newly developed double-clutch
sport automatic gearbox. Based on the M DCT transmission introduced
in the BMW M3, this 7-speed gearbox ensures faster acceleration and
extra performance in comparison with the 6-speed manual gearbox,
while providing the comfort features of a BMW automatic
transmission. The 7-speed double-clutch sport automatic shifts gears
without the slightest interruption of power.
The BMW Z4 sDrive35i with its seven-speed sport automatic
accelerates to 60mph in just 5.0 seconds, while fuel consumption is
expected to outperform the fuel economy on the same model with a
Sport automatic gives the driver the choice of either automatic
(Program D) or manual gear selection. If desired, the driver may
shift gears manually by means of paddles on the steering wheel.
The 6-speed sport automatic transmission available on the BMW Z4
sDrive30i promotes not only driving comfort, but also the sporty
performance of a BMW Roadster. Indeed, the characteristics of the
car are attributable to the direct connection linking the
transmission to the engine, based on modern torque converter
technology with an integrated torsion damper, avoiding unnecessary
slip and therefore helping to eliminate any loss of power and
performance. Even the slightest movement of the gas pedal,
therefore, is converted spontaneously into a quick response with
gearshift times reduced to a minimum.
The sport automatic transmission offers the driver the opportunity
to shift gears manually when desired. Apart from selecting gears via
the selector lever on the center console, the driver also has the
option to use the gearshift paddles on the steering wheel.

Rear-wheel drive, near
perfect weight distribution, the long wheelbase and the low center
of gravity on the roadster create ideal conditions for supreme
Featuring traditional spring-struts, a “double-jointed” front
suspension made largely of aluminum, and a constant-geometry rear
axle, the new Z4 comes with proven suspension concepts in a
configuration perfectly tailored to the characteristics of the car.
Electric power steering plays a role also in the BMW Z4, enhancing
the precision and comfort of steering maneuvers and reducing fuel
consumption, since the electric motor for steering power assistance
is activated only when required or desired by the driver.
The new Z4 comes with new high-performance brakes, featuring low
weight and low brake pad wear. At the same time the BMW Z4 is the
first car in its segment to feature an electrical parking brake
activated and released by a button on the center console.
Both versions of the new BMW Z4 come as standard on 17-inch
light-alloy rims and with runflat tires as well as a Tire Pressure
BMW’s standard Dynamic Stability Control (DSC) serves not only to
activate the ABS brakes and ensure stability on slippery surfaces by
activating the brakes or reducing engine power, but also comprises
other functions such as Brake Drying and Brake Standby as well as a
Start-Off Assistant. Acting in a similar way to a mechanical limited
slip differential, DSC electronic rear brake management is used to
simulate a limited slip differential for stronger acceleration in
Activating Dynamic Traction Control at the touch of a button, the
driver is able to raise the response thresholds for intervention by
the DSC, thus enjoying the option, for example, to set off on loose
snow with the drive wheels slightly spinning. And when desired, the
driver is also able to deactivate DSC altogether (ABS remains
Adaptive M Suspension featuring
Electronic Damping Control (EDC).
The agility of the BMW
Roadster may be further enhanced by ordering the optional Sport
Package featuring Adaptive M Suspension with Electronic Damping
Control. A central control unit varies the “compression” and
“rebound” stages on the four twin-sleeve gas pressure dampers to
provide optimum response at all times. The response time is so fast
that a signal coming from a front wheel crossing a hole in the road
reaches and re-adjusts the rear dampers even before the rear wheels
reach the same uneven road surface.
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

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

clearer orientation in choosing the next step in the operating
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
