We're not sure why http://www.autoblog.com/make/bmw/ - BMW is reticent to put forth a new Motorsports model of its http://www.autoblog.com/model/z4 - Z4 folding hardtop convertible, but it has effectively introduced such a model in all but name here at the http://www.autoblog.com/category/Detroit-Auto-Show/ - Detroit Auto Show .
Inscrutably dubbed Z4 sDrive35is (we're guessing you can hit extralegal
speeds by the time you successfully spit out its name), the new model
features a revised twin-turbo 3.0-liter inline-six that spits out 340
horsepower and 332 pound-feet of torque, with an overboost function
capable of a momentary bump up to 369 torques. Paired with BMW's
seven-speed Sport Automatic dual-clutch transmission, the drivetrain is
good for 0-62 miles-per-hour in in 4.8 seconds.
Additional alterations include a ride height that's lowered by 10
millimeters thanks to the adaptive M suspension, a revamped front
fascia with matte aluminum trim bars, Oxide Silver mirror caps, and
19-inch alloys among other niceties.
PRESS RELEASE
The Top Performer in the Roadster Range: The BMW Z4 sDrive35is.
* 13.12.2009
Munich. Combining classic proportions with modern sportiness, the new
BMW Z4 has reached the top of its market segment almost overnight. And
now this charismatic roadster is entering a new dimension in driving
dynamics, the new BMW Z4 sDrive35is offering an even higher standard of
performance ensured both by the modified straight-six power unit with
BMW Twin Turbo Technology and High Precision Injection, on the one
hand, and by BMW's seven-speed Sport Automatic with double clutch
operation and the M Sports Package including the adaptive M Suspension
likewise featured as standard, on the other. Appropriate optimisation
in engine technology increases maximum output of the 3.0-litre power
unit to 250 kW/340 hp. Peak torque is 450 Newton-metres/332 lb-ft,
increasing briefly with the Overboost function to 500 Newton-metres/369
lb-ft. The outstanding power and performance of the BMW Z4 sDrive35is
is expressed in particular by the significant increase in pulling power
and muscle to be clearly experienced in all situations. In conjunction
with seven-speed Sport Automatic featuring double clutch operation,
this new top-of-the-range
Roadster accelerates from a standstill to 100 km/h (62 mph) in just 4.8 seconds.
At 9.0 litres/100 kilometres (equal to 26.1 mpg US) and 210 grams in
the EU test cycle, fuel consumption and CO2 emissions are the same as
on the BMW Z4 sDrive35i with Sport Automatic.
The BMW Z4 sDrive35is is making its world debut at the 2010 North
American International Auto Show (NAIAS) in Detroit. And parallel to
the market launch of this high-performance roadster in spring 2010, the
M Sports Package is being introduced for all further versions of the
BMW Z4.
More air, more boost, more torque, more driving pleasure.
The twin-turbo straight-six power unit already giving the BMW Z4
sDrive35i truly impressive dynamics and all-round performance is
characterised in particular by its spontaneous and direct response to
the gas pedal, fascinating free-revving performance, and unusually
economical use of fuel for a car in this class.
Now the outstanding potential of this power unit is being put to even
greater use in the new version of the BMW Roadster, features such as
optimised air supply and increased boost pressure ensuring an even
better flow of power with the same high standard of efficiency.
The combination of BMW Twin Turbo Technology and High Precision
Injection offers a level of performance a naturally-aspirated power
unit would only be able to provide with a larger number of cylinders
and extra displacement, meaning far higher weight and significantly
greater fuel consumption.
Instead, the BMW Twin Turbo power unit uses two small turbochargers
which, through their low inertia, cut in from the start at relatively
low engine speeds, each supplying three cylinders with compressed air.
As a result, power and performance are built up with a level of
spontaneity quite unusual on a turbocharged engine. The turbocharger
system developed for the power unit of the new BMW Z4 sDrive35is
maintains a high boost pressure throughout the entire load range. Peak
torque now increased to 450 Newton-metres or 332 lb-ft comes from a low
1,400 rpm and is maintained consistently all the way to 4,500 rpm.
Maximum output of 250 kW/340 hp, in turn, is delivered at 5,800 rpm.
Overboost function for particularly dynamic acceleration.
Modified engine management on the BMW Z4 sDrive35is also allows the use
of an Overboost function briefly increasing engine torque under full
load by another 50 Newton-metres or 37 lb-ft. The peak thus offered of
500 Newton-metres/369 lb-ft gives the car particularly fast, dynamic
and powerful acceleration, the BMW Z4 sDrive35is completing the sprint
from a standstill to 100 km/h (62 mph) in just 4.8 seconds.
Through its particular characteristics, the power unit offers a
particularly intense experience of this supreme performance. The extra
output of the optimized
six-cylinder is maintained consistently throughout all load ranges, above all under very dynamic driving conditions.
When accelerating in the BMW Z4 sDrive35is, the driver feels the
additional torque and muscle particularly at medium and high engine
speeds. Following the policy of the BMW Group, finally, top speed of
the BMW Z4 sDrive35is is limited electronically to 250 km/h or 155 mph.
High Precision Injection: the efficient way to supreme performance.
The BMW Z4 sDrive35is offers its outstanding power and performance
consistently at all times. But this does not mean an increase in fuel
consumption and emissions. On the contrary – averaging fuel consumption
of 9.0 litres/100 kilometres (equal to 26.1 mpg US) and CO2 emissions
of 210 grams per kilometre in the EU test cycle, the new top model
offers the same superiority also in this respect as the BMW Z4
sDrive35i with Sport Automatic.
This unusually good balance of performance and fuel consumption results
from the fundamental design and layout of the six-cylinder combining
BMW Twin Turbo Technology with High Precision Injection. So once again,
the qualities of direct gasoline injection featured in this engine come
out very clearly, piezo-injectors positioned in the cylinder head
between the valves and therefore in the immediate vicinity of the spark
plugs ensuring particularly precise dosage of fuel and a clean
combustion process.
Opening up to the outside, the injectors operate at a pressure of up to
200 bar, distributing fuel in a conical spray pattern throughout the
entire combustion chamber. A further advantage of such direct fuel
injection is the cooling effect allowing higher compression and making
the combustion process even more efficient.
Through their concept alone, the turbochargers likewise help to reduce
fuel consumption. Since the turbines are made of special steel
particularly resistant to high temperatures and therefore able to cope
with temperatures of more than 1,000° C or 1,830° F, there is no need
for an increased fuel supply with its cooling effect. Particularly
under full load, this ensures a significant advantagein fuel economy.
Further technologies offered as standard by BMW EfficientDynamics such
as Brake Energy Regeneration, EPS Electric Power Steering and on-demand
control and management of ancillary units likewise help to reduce both
fuel consumption and emissions.
Characteristic engine sound accompanying the dynamic surge of power.
The modified six-cylinder also comes with special features on the
engine block itself in the interest of even greater strength and
stiffness. The exhaust system of the BMW Z4 sDrive35is, in turn, has
been developed specifically for this model, appropriate sound
engineering giving the car a very characteristic and truly impressive
sound pattern.
This particular distinction tailored to the BMW Z4 sDrive35is is
ensured by special sound flaps and modifications on the silencers. The
driver and passenger therefore experience powerful acoustic feedback to
their wish for performance, without the sound of the engine becoming
obtrusive, let alone annoying, at any time. So the sound experience is
characterised by a particularly deep rumble with the focus above all on
the low frequency range.
Seven-speed Sport Automatic with a special control map and an optimised two-mass flywheel.
The seven-speed Sport Automatic with double clutch operation featured
in the BMW Z4 sDrive35is likewise offers the very best in driving
dynamics and efficiency. A particular highlight in this case is the
two-mass flywheel laid out particularly for an even higher level of
power and performance, offering even greater strength and stability and
naturally handling high engine torque of up to 500 Newton-metres or 369
lb-ft without the slightest problem.
The seven-speed Sport Automatic with double clutch operation shifts
gears without the slightest interruption of torque and engine power,
offering the driver the choice of an automatic gearshift or the manual
selection of gears. The fast and particularly smooth change of gears
ensures unusually harmonious acceleration and serves in addition to
reduce both fuel consumption and emissions.
The control map on the seven-speed Sport Automatic transmission with
double clutch has naturally been tailored to the particular power and
performance of the engine, thus further enhancing the superior
sportiness of the BMW Z4 sDrive35is to an even higher level.
Particularly when shifting gears manually and in conjunction with the
SPORT and SPORT+ modes of Dynamic Driving Control, the transmission
offers a most dynamic experience through modified gearshift points,
optimised selection of gears and an even greater increase in torque
before shifting.
Sport Automatic also comes with a Launch Control function for maximum performance when accelerating from a standstill.
The Sport Automatic transmission is controlled and masterminded by an
electronic gear selector on the centre console and comes with gearshift
paddles on the steering wheel.
Featured as standard on the BMW Z4 sDrive35is: M Sports Package and adaptive M Suspension.
The BMW Z4 sDrive35is also comes as standard with an M Sports Package
including the M Aerodynamics Package and adaptive M Suspension
featuring electronically controlled dampers for even greater agility
without making any concessions in terms of comfort. The M Sports
Package underlines the dynamic character of the car through its
aerodynamically optimised exterior features and customised interior
design. Special 18-inch light-alloy rims in five-spoke design combined
with tyres of different size front and rear round off the sporting
character of the BMW Z4 sDrive35is, with 19-inch light-alloy rims
available an option.
The adaptive M Suspension lowers the entire car by 10 millimetres or
almost 0.4", ensuring a quick reaction to sudden steering manoeuvres
and superior precision when entering a bend thanks to four continuously
adjustable twin-sleeve gas-pressure dampers with interacting adjustment
of the inbound and rebound strokes. The central control unit processing
data delivered by three accelerometers and adjusting the four dampers
independently of one another enables the suspension to respond very
quickly to even the slightest change in driving and road conditions.
Damper harshness, in turn, is adjusted by externally fitted valves
controlling the flow of damper fluid, giving the dampers either a
harder or softer set-up in accordance with current conditions and
driving requirements. Reaction time of the system is extremely short,
with the rear dampers being adjusted immediately as soon as the front
wheels run over a hole or bump in the road.
Electric Power Steering on the BMW Z4 sDrive35is features a
particularly sporting and dynamic control map, with the focus on
intense and clear feedback to the driver through the dosage of power
assistance provided by the electric motor. Again, this enables the
driver to enter bends with extreme precision at all engine speeds in
the interest of enhanced performance.
M Sports Package offering a most direct experience of the car's dynamic
potential – and available as an option also on the other models in the
range.
The exterior and interior features of the M Sports Package coming as
standard on the BMW Z4 sDrive35is raises the dynamic driving potential
of the car to an even higher level and clearly presents the particular
qualities of this model through its looks alone.
Upon introduction of the new top model in the range, the M Sports
Package is also becoming available as an option on the other versions
of BMW's unique Roadster. The only difference is that instead of the
wheels exclusive to the BMW Z4 sDrive35is, the other models come with
18-inch M light-alloy wheels on the
M Sports Package.
The particular exterior features on the BMW Z4 sDrive35is include a
striking front bumper with a horizontal trim bar in the outer air
intakes finished in matt aluminium, like the bars in the BMW kidney
grille. The slightly twisted contours of these trim bars take up the
spoke design of the light-alloy rims as a further sign of distinction.
The rear bumper comes with specially accentuated surrounds on the
exhaust tailpipes as well as a two-piece diffuser again created
specifically for the BMW Z4 sDrive35is, finished at the top in body
colour and featuring a black grained surface at the bottom. The M
Aerodynamics Package included in the optional M Sports Package also on
the other versions of the Z4 Roadster furthermore comes with a rear
bumper insert in Anthracite metallic.
Inside the BMW Z4 sDrive35is, the driving experience is enhanced to an
even higher standard by features such as the M leather steering wheel
with its gearshift paddles, an M footrest and sports seats. The
instrument cluster comes with grey faces on the dials and the
"sDrive35is" model designation in the instrument cluster.
Further features inside the BMW Z4 sDrive35is are the
Anthracite-coloured BMW Individual roof lining, M entry strips,
footmats with coloured piping and the "sDrive35is" model designation,
as well as M interior trim in Aluminium carbon.
The M Sports Package on the other versions of the Z4 Roadster includes
an M gearshift lever knob in leather on the manual gearbox models. At
the same time the range of leather upholstery is being further enhanced
by an additional colour variant marking the launch of the BMW Z4
sDrive35is: Both the top model and all other versions of the Z4
Roadster are now also available in Kansas Walnut leather as yet a
further option.
The BMW Z4 sDrive35is comes with a choice of six paintwork colours. In
addition to Alpine White and the metallic colours Titanium Silver,
Sapphire Black, Space Grey and Deep Sea Blue, the Z4 Roadster is now
available for the first time in Melbourne Red metallic.
Regardless of the colour chosen, the exterior mirror caps on the BMW Z4
sDrive35is always come in Oxide Silver. Another optical feature on the
top model, finally, is the "sDrive35is" model designation on the front
side panels.
