The German carmaker showed two world premiers: The new BMW Z4 Roadster
from the US Spartanburg plant will be presented for the first time to
the public, as will the especially powerful BMW Z4 M Roadster of BMW M
GmbH.
These are perfectly complemented by the BMW Z4 Coupe which is close to
production and which offers additional potential in the near future for
this series in the areas of design, technology and performance. At NAIAS
2006, where around 800,000 visitors from the U.S. and from abroad are
expected from the 8th through the 22nd of January, the BMW Group will
also dedicate itself particularly intensively to the development of innovative
drive concepts.
With the BMW Concept X3 EfficientDynamics, the company shows how the intelligent
management of energy streams can contribute to the reduction of fuel consumption
and emissions. With its innovative injection technology, the recovery
of braking energy, the Automatic Start-Stop system and the BMW Active
Hybrid drive system, this technology medium is able to unite maximum dynamic
performance with a maximum of efficiency.
A unique engine in an extraordinary vehicle – this combination is
the essence of the special attraction of the new BMW Z4 M Roadster. Its
252 kW/343 hp M Series six-cylinder engine with displacement of 3.2 liters
and torque of 365 Nm catapults the open two-seater to 100 km per hour
in just 5.0 seconds. The variable M differential lock, the advanced suspension
and the high-performance braking system provide optimum traction, unique
handling and a high degree of active safety. In terms of appearance, the
Z4 M Roadster’s front spoiler with large air intakes, the standard
bi-xenon headlights, the twin-spoke design of the 18-inch wheels and the
typical M rear end with four tailpipes and diffuser make it stand out.
With visual accents which underscore its dynamic performance, the new
BMW Z4 Roadster is taking off into the year 2006. It is above all the
innovations under the hood which will provide additional driving pleasure.
The new 3.0-liter six-cylinder engine in the BMW Z4 Roadster 3.0si (195
kW/265 hp, 315 Nm) accelerates the two-seater, which has a top speed of
up to 250 km/h, from 0 to 100 km/h in just 5.7 seconds. As a new option,
there is now a six-speed automatic transmission with shift paddle on the
steering wheel.
The range of engines now features two new 2.5-liter six-cylinder engines.
In the BMW Z4 Roadster 2.5si, the power unit delivers 160 kW/218 hp and
generates torque of 250 Nm with a top speed of 240 km/h. The second engine
variant (130 kW/177 hp, 230 Nm) gives the BMW Z4 Roadster 2.5i a top speed
of up to 229 km/h. The 2-liter four-cylinder engine in the BMW Z4 Roadster
2.0i (110 kW/150 hp, 200 Nm) completes the range of engines. Even this
model variant achieves a top speed of 220 km/h.
Also at NAIAS 2006, the concept study BMW Z4 Coupe is designed to attract
all visitors who are looking for modern examples of fascinating automobile
design. With this showpiece, the BMW brand is setting new stylistic, conceptual,
and technological trends. The BMW Z4 Coupe concept study offers the prospect
of a two-door car which thanks to its superior performance embodies the
classic values of the brand.
High Precision Injection und Brake Energy Regeneration: BMW technology
innovations allow significantly reduced fuel consumption for all models.
At NAIAS 2006 in Detroit, BMW will present a series of innovative drive
technologies which especially in combination will result in significant
consumption reductions without any sacrifice in terms of driving performance.
The fuel injection technology “High Precision Injection”,
which BMW will introduce within the next few years, is the jet-guided
direct fuel injection system suitable for large-scale production.
This will realize the full potential for savings in fuel consumption,
which the solutions on the market have been unable to achieve up to now.
Known as Brake Energy Regeneration, the BMW Group is introducing a system
for recovering energy which in the past was released as heat at the brake
disks but now through intelligent alternator regulation can be utilized
for the reduction of fuel consumption. The system is complemented by an
automatic engine start-stop system.
For high-performance models, the BMW Group is developing the exemplary
drive concept BMW Active Hybrid, the BMW interpretation of a hybrid drive
based on active transmission and Super Caps. In this concept, the advantages
of the electric drive unit are used not only to reduce fuel consumption
but also to improve acceleration behavior.
