Range-topping Z4 sDrive35is model makes world premiere at NAIAS.
Woodcliff Lake, NJ – December 12, 2009, 6pm EST... Combining
classic proportions with modern features, the BMW Z4 Roadster enjoys
the top spot in its market segment. Now, the new BMW Z4 sDrive35is
distills the Roadster’s performance potential to produce one of
BMW’s fastest and best-handling Roadsters ever. The BMW Z4
sDrive35is is making its world debut as a 2011 model at the 2010 North
American International Auto Show (NAIAS) in Detroit. It arrives at
authorized BMW Centers in Spring 2010.
More air, boost, and torque: More BMW performance.
The latest Z4 model is characterized by instantaneous response to the
accelerator pedal, fantastic sounds, and a free-revving spirit. The
engine features increased air intake flow and increased boost pressure
to release more power with the same standard of efficiency. The
combination of twin low-mass turbochargers and High Precision direct
injection offers an output a naturally-aspirated engine would only be
able to provide through more cylinders and larger displacement.
The turbocharger system developed for the engine of the new BMW Z4
sDrive35is maintains a high output throughout the entire engine speed
range. Nominal peak torque is increased to 332 lb-ft from 1,500 rpm to
4,500 rpm. Maximum output of 335 hp is delivered at 5,900 rpm.
Overboost function for athletic acceleration.
The enhanced engine management system of the BMW Z4 sDrive35is
includes an electronically-controlled overboost function to briefly
increase torque under full load by another 37 lb-ft. This temporary
torque peak of 369 lb-ft gives the car a significant increase in
acceleration. The BMW Z4 sDrive35is will complete the sprint from a
standstill to 60 mph in just 4.7 seconds (preliminary). Top speed of
the BMW Z4 sDrive35is is limited electronically to 250 km/h or 155 mph.
High Precision direct injection and BMW EfficientDynamics.
The BMW Z4 sDrive35is offers outstanding power and performance
without an increase in fuel consumption or emissions. Its figures are
expected to match those of the BMW Z4 sDrive35i with Double-Clutch
Transmission on the EPA test cycle. This balance of performance and
fuel efficiency results from the fundamental design and layout of the
BMW inline-6, which combines twin turbochargers with High Precision
direct injection. The fuel injectors operate at a pressure of up to
200 bar (2900 psi), distributing fuel in a conical spray pattern
throughout the combustion chamber. Another advantage of direct fuel
injection is its cooling effect which allows higher compression while
reducing the possibility of detonation.
Further technologies offered under the BMW EfficientDynamics
philosophy include Brake Energy Regeneration, Electric Power Steering,
and on-demand operation of engine accessory units.
Signature engine sound to accompany the surge of power.
The exhaust system of the BMW Z4 sDrive35is has been tuned
specifically for this model. Acoustic engineering gives the car a very
unique sound pattern across the speed range. This tuned sound is the
result of special baffles and a unique set of mufflers. The sound is
characterized by a deep rumble with a focus on the low frequency sound range.
Enhanced Electric Power Steering.
Electric Power Steering (EPS) on the BMW Z4 sDrive35is features very
sporty programming, focused to provide intense and clear steering
feedback to the driver. This enables the driver to turn-in with
remarkable precision and confidence at all vehicle speeds.
7-speed Double-Clutch Transmission with special programming.
The standard 7-speed Double-Clutch Transmission (DCT) in the BMW Z4
sDrive35is combines the best in driving dynamics and efficiency. A
highlight is the dual-mass flywheel, configured for the higher levels
of power and performance. The DCT can shift gears without the
slightest interruption of power to the rear tires, and offers a choice
of automatic or manual gear selection. The programming of the DCT has
been tailored to complement the sporty nature of the BMW Z4 sDrive35is
at every level.
When shifting gears manually or within the SPORT and SPORT modes of
the Z4’s standard Driving Dynamics Control, the transmission
offers an exciting experience through faster gearshifts and a greater
increase in torque before shifting. The DCT also features a Launch
Control function for maximum performance when accelerating from a
standstill. The DCT is controlled by an electronic gear selector on
the center console and comes with gearshift paddles on the steering wheel.
M Sport upgrades to match the new engine’s performance.
The BMW Z4 sDrive35is includes new M Sport upgrades such as M
Aerodynamics and adaptive M Suspension. The adaptive M Suspension
combines a ride-height reduction of 10 millimeters (almost 0.4”)
with electronically controlled shock absorbers (Dynamic Damping
Control) to improve the vehicle’s agility without compromising
ride comfort. The M Sport upgrades emphasize the Z4’s athletic
character through aerodynamically optimized exterior features and
customized interior components.
Special 18-inch light-alloy wheels in five-spoke design round off the
sporty character of the Z4 sDrive35is. 19-inch light-alloy wheels are
available as an option. In addition to its unique wheels, the new
model is further distinguished by a striking front bumper with a matte
aluminum trim bar in each outer air intake, a rear bumper with
accentuated surrounds on the tailpipes, and a rear diffuser finished
at top in body color and black textured surface underneath.
M Sport interior enhancements and new Kansas Walnut leather.
Inside the BMW Z4 sDrive35is, the driving experience is enhanced by
features such as a new thick-rimmed M leather steering wheel with
gearshift paddles, an M driver’s footrest, and sport seats.
Grey-faced instrument dials feature the “sDrive35is” model
designation. Further features inside the Z4 sDrive35is are the
Anthracite-colored BMW Individual roof lining, M door sill strips,
floor mats with colored piping and the “sDrive35is” model
designation, as well as M interior trim in Aluminum Carbon. The new
Aluminum Carbon trim features the recognizable “weave” of
natural carbon fiber interpreted on a matte aluminum base.
The range of leather upholstery is being further enhanced by an
additional color variant marking the launch of the BMW Z4 sDrive35is:
All versions of the Z4 Roadster are now also available in Kansas
Walnut leather as an option. The BMW Z4 sDrive35is is available
with a choice of six paintwork colors. In addition to Alpine White and
the metallic colors Titanium Silver, Black Sapphire, Space Grey, and
Deep Sea Blue, the Z4 Roadster is now available for the first time in
Melbourne Red metallic. Regardless of the color chosen, the exterior
mirror caps on the BMW Z4 sDrive35is are always Oxide Silver.
