The new BMW Z4 Roadster
in BMW’s roadster family has been revealed. The all-new BMW Z4
will go on sale in Europe in 2009 and features a host of
innovations never before showcased during BMW’s 75 years of
The BMW Z4
is the first to come with a two-piece, electro-hydraulically
operated Retractable Hard-Top roof that can be raised or lowered
in 20 seconds. The new roadster is also the first vehicle to be
offered with Adaptive M Suspension. Electronically controlled
dampers offer three different configurations and lower the ride
height by up to 10mm for a more dynamic drive. By way of
comparison, the Sport+ setting of the new car is comparable to
the outgoing Z4’s standard ride comfort level.
standard Drive Dynamic Control function is another first and
allows the driver to alter, depending on model specification,
the throttle and steering response, level of ride comfort,
Dynamic Stability Control response and, on automatic or Double
Clutch Transmission cars, gear change times.
the new BMW Z4 is a choice of three six-cylinder powerplants.
The range flagship is the current International Engine of the
Year-winning 3.0-litre twin-turbocharged engine.
Producing 228kw at 5,800rpm, the BMW Z4 sDrive35i accelerates
from zero to 100km/h in 5.2 seconds (5.1 seconds for a Double
Clutch Transmission-equipped car) and on to an
electronically-limited top speed of 250km/h. The
twin-turbocharged 2,979cc engine with high-precision direct
injection technology produces 400Nm of torque from just 1,300rpm
for effortless in-gear acceleration. The strong performance
credentials are matched in terms of economy and emissions.
this model in the launch line-up are the Z4 sDrive23i and the Z4
sDrive30i. Both use the same magnesium aluminium alloy engine
with Double VANOS and VALVETRONIC technology, but with varying
six-cylinder powerplants surpass the latest strict EU5 emissions
Transmitting the power to the road in all three Z4s is a
six-speed manual gearbox as standard. Customers of the Z4
sDrive23i and the Z4 sDrive30i who prefer the characteristics of
an automatic can specify a six-speed Sport Automatic
transmission featuring gear change paddles on the steering
wheel. Buyers of the Z4 sDrive35i can choose the more advanced
seven-speed Double Clutch Transmission, again with gear shift
paddles located on the steering wheel.
All of the latest BMW Z4s come as standard with facets of BMW’s
award-winning EfficientDynamics programme. Technologies that
improve engine performance while enhancing economy and cutting
emissions include Brake Energy Regeneration, Electric Power
Steering with Servotronic, Reduced Rolling Resistance Tyres,
on-demand control of the engine’s ancillaries and Optimum Shift
Indicator on manual transmission cars. The BMW Z4 also adheres
to a philosophy of lightweight construction with the front
suspension and subframe being largely made from aluminium.
The new BMW Z4 is larger than its predecessor measuring 148mm
longer at 4,239mm and 9mm wider at 1,790mm, and this results in
greater interior space and luggage capacity. With the roof up,
headroom has been increased by 44mm while the greater car width
and design enhancements have led to 20mm more shoulder room and
43mm more elbow room.
first time on a BMW Z4 there is a bespoke storage facility
located behind the driver and passenger seats. This approximate
15.5-litre single compartment stretches the width of the car’s
interior and features netting to hold the contents in place. It
can be complemented by an optional Storage Package that adds
further stowage capacity. BMW’s latest generation of iDrive
makes its first appearance on a Z4. The BMW Professional
Multimedia Navigation system features a hard disc drive capable
of 12Gb of audio file storage and BMW ConnectedDrive
functionality. The system also comes with eight programmable
Favourite buttons as system shortcuts.
roof construction of the BMW Z4 creates a boot that varies in
capacity from 180 to 310 litres – large enough to stow a full
set of golf clubs. For the first time on a BMW Z4 customers can
specify a through-loading system for additional storage
capability. A hatch between the two seats permits a second full
set of golf clubs to be carried.
visibility in the BMW Z4 has also been improved. All round
visibility is up by 14 per cent while, courtesy of the four
electric windows creating a larger glasshouse, side visibility
is up 40 per cent. The Retractable Hard-Top roof features a
glass rear window and this too improves visibility by 52 per
