1. Description in Brief.

• 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.
