Re-launch of BMW's successful Roadster in modern and authentic style.
The new BMW Z4 offers a unique driving experience combining outstanding
pleasure with supreme sportiness. • First BMW Roadster with a
retractable hardtop. The new model is the successor to both the BMW Z4
Roadster and the BMW Z4 Coupé. • New BMW Z4 with an
extra-long front lid, large wheel arches, long wheelbase and small
overhangs. Unmistakable look with a low-slung front end, a striking
shoulder line and the rear end accentuating the sheer width of the car.
The engine compartment lid extending beyond the wheel arches, the large
BMW kidney grille, intake gills at the side, black A-pillars, the
contoured roof and rear lights in innovative light technology set
characteristic highlights. • Two-piece electrohydraulically
retractable hardtop in lightweight aluminium shell construction. The
hardtop opens and closes fully automatically in each case within 20
seconds, the roof elements coming to rest in the roof compartment to
give the car a low-slung rear-end design reflecting the traditional
proportions of a roadster as well as a large luggage compartment
ranging in capacity from 180-310 litres (6.3-10.9 cu ft). The
high-quality interior lining finished in an extra-light colour as well
as large windows including the heated glass window at the rear ensure
an exclusive ambience and optimised all-round visibility. •
Driving comfort and the feeling of space in the new BMW Z4 achieve a
standard quite unique in this segment. Head and elbow room as well as
the degree of comfort in entering the car have been significantly
enhanced over the former model. The low seating position near the rear
axle guarantees the driving experience typical of a BMW Roadster.
High-quality materials, first-class quality of finish and
driver-oriented design of both the instrument panel and the centre
console guarantee an emotional driving experience in a particularly
refined ambience. • Wide range of storage options within the
passenger compartment including a spacious crosswise storage
compartment behind the seats. The optional storage package and
through-loading including a transport bag for bulky items of luggage
such as skis or a golf bag ensure even greater variability. •
First use of the BMW iDrive control system in the BMW Roadster. In
conjunction with the optional Professional navigation system the new
generation of BMW iDrive comprises an ergonomically optimised
Controller for the selection and control of functions by turning,
pressing and tipping the Controller, function buttons on the Controller
for direct menu entry, freely programmable favourite buttons for even
easier operation, as well as a folding 8.8-inch display with
high-resolution graphic presentation and an optimised menu structure.
Enhanced navigation system with an even wider range of functions in
entering destinations, planning trips and presenting maps. Optional
audio system with hard disc memory. Unrestricted use of the internet in
the car as an option in conjunction with the Professional navigation
system. • Introduction of the new BMW Z4 with a choice of three
straight-six power units ranging in output from 150 kW/204 hp to 225
kW/306 hp. All versions offering an optimum combination of acceleration
and fuel economy in their respective class. BMW EfficientDynamics
featured as standard with specific highlights tailored to each model:
variable VALVETRONIC valve management or, respectively, High Precision
Injection direct petrol injection technology, Brake Energy
Regeneration, on-demand management of ¬ancillary units,
map-controlled oil pump, gearshift point indicator, all-aluminium or,
respectively, composite magnesium/aluminium crankcase, optimised
aerodynamics, intelligent lightweight technology, tyres with reduced
roll resistance. All engine variants fulfil the future EU 5 emission
standard. • Seven-speed sports automatic with double clutch as an
option on the BMW Z4 sDrive35i. Shifting gears without the slightest
interruption of ¬traction, the transmission provides a unique
combination of the extra comfort of a BMW automatic transmission with
maximum dynamism and performance. Acceleration and fuel economy
improved once again over the manual gearbox models. Six-speed sports
automatic with optimised gearshift dynamics, direct connection to the
engine and minimised converter slip available as an option on the BMW Z4
sDrive30i and BMW Z4 sDrive23i. All sports automatic transmissions with
gearshift paddles on the steering wheel. • Outstanding driving
dynamics thanks to harmonious axle load distribution, rear-wheel drive
and lightweight aluminium suspension with a double-joint tiebar front
axle and centrally guided rear axle. Electromechanical power steering,
high-performance brakes, latest generation of DSC Dynamic Stability
Control. Dynamic Drive Control featured as standard allows the driver to
set up the car in three stages at the touch of a button. Dynamic
Driving Control acts on the gas pedal control map, engine management,
DSC response, the power steering control map, the dynamic gearshift on
the optional sports automatic transmission and, on cars fitted with the
optional, Adaptive M Suspension, the control map for electronic damper
adjustment. • Comprehensive safety concept with extremely stiff
body structures, defined load paths, specific use of high-strength
steel and special deformation elements, head/thorax airbags integrated
at the front and at the side in the seat backrests, three-point
inertia-reel seat belts with new belt tightening technology, massively
reinforced A-pillars and roll bars behind the headrests, runflat tyres
and a Tyre Defect Indicator fitted as standard, dual headlights with
bi-xenon light technology likewise featured as standard equipment.
