BMW's Vision
EfficientDynamics
|
BMW Vision EfficientDynamics |
BMW sees technical
innovations reducing both emissions and fuel consumption as an
elementary part of the brand’s product strategy, just like
vehicle concepts enhancing the Sheer Driving Pleasure so typical
of BMW as a lasting, sustained experience.
Now the BMW Vision
EfficientDynamics concept car clearly demonstrates that these
objectives expressed through the BMW EfficientDynamics
development strategy are fully compatible with the most
demanding reduction in fuel consumption and emissions complying
in full with future requirements.
Conceived as a
2+2-seater with plug-in full-hybrid technology, this unique car
is able to combine the performance of a BMW M Car with a
standard of fuel economy and emission management exceeding even
the current level achieved by the latest small cars in the
market. |
|
|
|
This outstanding result
is made possible by the consistent integration of BMW ActiveHybrid components,
their combination with an extremely economical combustion engine, and the
outstanding aerodynamic qualities of the BMW Vision EfficientDynamics concept
car.
BMW Vision
EfficientDynamics is the result of an all-inclusive development process starting
from a clean sheet of paper. This ensures an improvement of both efficiency and
driving pleasure far exceeding the sum total of all individual components and
technologies, and is also borne out in the very emotional design of this unique
concept car. BMW Vision EfficientDynamics is therefore an unprecedented sports
car offering fascinating perspectives for the future of Sheer Driving Pleasure
combined in full harmony with maximum efficiency.
Presenting this unique
concept car, BMW is once again demonstrating the company’s outstanding
competence in the development of cutting-edge drive systems. Indeed, BMW Vision
EfficientDynamics is the most comprehensive implementation of the BMW
EfficientDynamics development strategy seen so far. |
The drive units provide a
top speed limited electronically of 250 km/h or 155 mph, with
acceleration to 100 km/h in 4.8 seconds. Average fuel consumption in the
EU test cycle is 3.76 litres/100 kilometers, equal to 75.1 mpg imp, and
the CO2 emission rating is 99 grams per kilometer.
CO2 emission management is
even more outstanding when driving in the all-electric mode after
charging the battery from a plug-in source: Taking all emissions in the
generation of electricity into account, as prescribed by the EU mix, the
car’s emission rating in this case is just 50 grams per kilometer.

Through this unique
balance of driving pleasure and fuel economy the BMW Vision
EfficientDynamics concept car clearly demonstrates the potential
of BMW ActiveHybrid technology making its world debut at the
2009 Frankfurt Motor Show in the BMW ActiveHybrid X6 and BMW
ActiveHybrid 7 production models.
This truly
impressive power and performance is made possible by combining a
particularly fuel-efficient three-cylinder turbodiesel with one
electric motor each on the front and rear axle.
The intelligent
combination of these three power units and the energy they
develop, together with precisely controlled energy management,
serves to enhance both the dynamic performance and the all-round
efficiency of the car, using the full potential of BMW
ActiveHybrid to reduce both fuel consumption and CO2 emissions
to the greatest possible extent. Overall system output is 262
kW/356 hp, peak torque is 800 Newtonmetres/ 590 lb-ft.
The special
arrangement of the three power units allows all-wheel drive also
available in the all-electric mode. The result is minimum power
loss and at the same time harmonious transmission of the power
available under all conditions.
In its design, BMW
Vision EfficientDynamics for the first time conveys the dynamic
look so typical of a BMW sports car to a hybrid vehicle.
Developed with know-how from Formula 1, the body of this unique
sports car is an expression of intelligent lightweight
technology and supreme aerodynamic efficiency.
And in the design of
the interior, the focus was likewise on both the fascinating
driving experience and, in particular, on transparent, hands-on
technology and maximum reduction of weight.
• High-performance
concept study with BMW ActiveHybrid technology visualising the
dynamic performance typical of a BMW against the backdrop of
future demands in sustained mobility. BMW Vision
EfficientDynamics as a symbol for the future of Sheer Driving
Pleasure in harmony with trendsetting efficiency.
• Development aim:
The performance of a BMW M Car and a highly emotional character
combined with the fuel economy and emission management of a
modern small car in the premium class. As a result, this unique
sports car offers the most consistent rendition of the BMW
EfficientDynamics development strategy.
• Innovative
approach in the context of BMW EfficientDynamics: The
exceedingly good balance of CO2 emission management and driving
pleasure results from a revolutionary vehicle concept developed
all in one from the ground up, achieving a new level of
efficiency combined with a unique driving experience. The
overall result goes far beyond the sum total of the individual
features and components in this concept car.
• BMW Vision
EfficientDynamics offers a realistic impression of the unique
potential of BMW ActiveHybrid technology and the great
innovative thrust of BMW EfficientDynamics. |
Technology
• Offering a full-hybrid
concept, the BMW Vision EfficientDynamics concept car is powered by a
three-cylinder turbodiesel and two electric motors. Overall system
output is 262 kW/356 hp, maximum torque 800 Newton-metres/590 lb-ft.
All-wheel drive featuring an electric motor on both the front and rear
axle.
• Anticipated performance:
Acceleration from a standstill to 100 km/h in 4.8 seconds, top speed 250
km/h (155 mph) (electronically limited) , fuel consumption in the EU
test cycle 3.76 litres/100 km (equal to 75.1 mph imp), CO2 emissions 99
grams/kilometre.
• As a plug-in hybrid, BMW
Vision EfficientDynamics is able to cover the entire fuel consumption
drive cycle under electric power alone. Taking the sources of energy
used for generating the electric power consumed into account (EU
electricity mix), this reduces the CO2 emission rating to just 50 grams
per kilometre.
• Electric power is
generated without the slightest increase in fuel consumption through a
particularly efficient concept of Brake Energy Regeneration. Energy is
stored in 98 lithium polymer cells. The car is able to cover a distance
of approximately 50 km/31 miles in the electric mode alone.
• Aerodynamics developed
with know-how from Formula 1. CX drag coefficient optimised to just
0.22. Forward-looking energy management uses the maximum potential
available in each case to minimise fuel consumption.
Design
• Technology-oriented body
design as a clear expression of consistent lightweight technology and
aerodynamic quality. Design language typical of the brand, setting clear
signals in terms of sporting performance and optimum efficiency.
• The 2+2-seater concept
combines dynamic performance and supreme efficiency with an enhanced
level of all-round function. BMW Vision EfficientDynamics symbolises
BMW’s commitment to offer an unprecedented driving experience for up to
four occupants.
• BMW Vision
EfficientDynamics comes with gullwing doors opening up to the side.
Innovative, weight-optimised door kinematics makes entering the car at
both front and rear convenient and very easy.
• The interior of this
unique 2+2-seater intentionally demonstrates the very latest in modern
technology. At the same time the use of natural materials underlines
BMW’s strategy of sustainability borne out through this concept car.
• The roof and door inserts
made of polycarbonate glass automatically become darker as a function of
incoming light.
