Wing doors facilitate entry to
both rows of seats, while extensive aerodynamic measures reduce
the drag coefficient to 0.22. The combination of a 3-cylinder
turbo diesel with a hybrid synchronous motor at the front axle
and a full-hybrid engine at the rear axle enables an overall
system output of 241 kW/328 bhp. The innovative design of the
BMW ActiveHybrid technology allows performance figures at the
level of a sports car, with just 4.8 seconds required for the
sprint from zero to 100 km/h - with an average fuel consumption
in the EU test cycle (KV01) of 3.76 litters/100 kilometers,
equal to 75.1 mpg imp, and a CO2 emission rating of 99 grams per
kilometer (1,3 l/100km and 33g CO2/km; EU-PHEV ECE-R101).
This unique relation between
dynamic performance and efficiency derives from the high level
of efficiency of all engine components as well as intelligent
linking of the power output of the three engines, as well as
precisely controlled energy management including brake energy
regeneration. What is more, the study BMW Vision
EfficientDynamics is conceived as a so-called plug-in hybrid.
The lithium-polymer rechargeable battery housed centrally in a
longitudinal chassis element and designed specially for this
hybrid sports car can be fully charged at a conventional power
socket within just two and half hours. The use of electrical
energy alone permits zero-emissions motoring with a range of
some 50 kilometres, while a 24-litre diesel tank extends the
total action radius of the vehicle to up to 700 kilometres.
By developing a sports car based
on the BMW Vision EfficientDynamics concept study for serial
production, the Munich-based premium automobile manufacturer
underscores its position as a global leader in the production of
sporty vehicles with exemplary efficiency. All current models
are fitted as standard with extensive measures for the reduction
of fuel consumption and CO2 emissions. The innovations used for
this purpose are based on the development strategy BMW
EfficientDynamics, which also includes BMW ActiveHybrid
technology as well as purely electrical drive systems. With the
BMW ActiveHybrid 7 and the BMW ActiveHybrid X6, two serial
production vehicles have already been launched in which a
BMW-specific combination of combustion and electric drive
results in an especially efficient increase in the driving
dynamics so characteristic of the brand.
The BMW Group is also undertaking
extensive field tests in regular traffic, which after the MINI E
will soon include the BMW ActiveE, so as to prepare for serial
production of a purely electrically powered model which is to be
produced at the BMW plant in Leipzig from 2013 as the Megacity
Vehicle.
At the same time, the current
technology showcase vehicle being presented to mark the
expansion of the BMW Leipzig plant not only demonstrates the
consistent further development of BMW ActiveHybrid as a drive
concept. It also highlights the expertise of the BMW Group in
the integrated development of vehicle concepts which are geared
towards the principles of BMW EfficientDynamics in every detail.
Like the Megacity Vehicle, the sports car based on the BMW
Vision EfficientDynamics study is an example of how
future-oriented mobility opens up fascinating perspectives in
combination with the driving pleasure characteristic of BMW.
