The latest BMW Concept Car for the
Efficient Dynamics
BMW has made the reduction of emissions and fuel consumption a key part
of its product development strategy, just as enhancements to the dynamic
ability of each BMW have been a lasting, sustained brand value. BMW's Efficient
Dynamics engineering philosophy – the pursuit of an enhanced, athletic driving
experience while simultaneously lowering the consumption and emissions of each
vehicle – resulted in the most dramatic drop in fleet consumption of any
automaker from 1990 through 2005, according to an Environmental Defense study.
Now, the BMW Vision concept car clearly demonstrates that the Efficient
Dynamics objectives are fully compatible when applied to a sports car.
Conceived as a 2+2-seater with plug-in full-hybrid technology, this unique car
combines the performance of a BMW M vehicle with a standard of fuel efficiency
and emission management that exceeds even the current levels achieved by the
latest small cars. This outstanding result is made possible by the combination
of BMW Active Hybrid components with an extremely economical combustion engine,
and outstanding aerodynamic qualities.
BMW Vision Efficient Dynamics is the result of a
"clean-sheet" development process to ensure that the correct
achievements were made in the areas of efficiency, driving pleasure,
technology, and emotional design. BMW Vision Efficient Dynamics is the most
comprehensive implementation of the Efficient Dynamics philosophy seen so far.
The power train provides a top speed limited electronically to 155 mph, with
acceleration to 100 km/h in 4.8 seconds. Average fuel consumption in the EU
test cycle is 3.76 liters/100 kilometers, equal to 62.6 mpg, 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 formula, the car's emission rating is
just 50 grams per kilometer.
Through this unique balance of driving pleasure and fuel efficiency,
the BMW Vision Efficient Dynamics concept car clearly demonstrates the
potential of BMW Active Hybrid technology, which makes its world debut at the
2009 Frankfurt Motor Show in the BMW Active Hybrid X6 and BMW Active Hybrid 7
production models.
The power and performance are made possible by combining a
fuel-efficient 3-cylinder turbo diesel with one electric motor on each axle.
The intelligent combination of these units, together with precisely controlled
energy management, simultaneously enhances the dynamic performance and the
efficiency of the car. Overall system output is 356 horsepower, and peak torque
is 590 lb-ft. The special arrangement of the two motors and diesel engine
allows all-wheel drive when driving in all-electric mode. The result is minimum
power loss and a harmonious transmission of the power available under all
conditions
In its design, BMW Vision Efficient Dynamics for the first time conveys
the dynamic look of a BMW sports car to a hybrid vehicle. Developed with
decades of experience in Motorsport, the body of this unique sports car is a
result of intelligent lightweight technology and aerodynamic efficiency. 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.
