It was one of the attractions of the Frankfurt Motor
Show (IAA) in 2009: a BMW four-seater sports car with charismatic design, fascinating performance
figures and unsurpassed efficiency, powered by BMW ActiveHybrid technology and presented under the
title BMW Vision EfficientDynamics. With its wide range of completely or virtually production-ready
components, this concept study met with an enthusiastic response. There was a widespread desire to
put the car on the road, and the realisation of this desire is moving considerably closer. At the
Leipzig trade fair centre BMW is presenting a fully road-ready technology showcase vehicle based
on the BMW Vision EfficientDynamics concept study. This presentation will give media
representatives their first ever opportunity to find out what it is like to drive the 2+2-seater
car powered by an innovative hybrid system.
The concept study BMW Vision EfficientDynamics represents the future of driving pleasure from a
BMW perceptive. Since its world premiere at the IAA 2009 it has received several awards both for
its futuristic design and its ground-breaking engine technology. Just 1.24 metres high, the
2+2-seater takes up the characteristic BMW shaping style, geared consistently towards aesthetic
appeal and dynamic performance. 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 litres/100 kilometres, equal to 75.1 imperial mpg, and a CO2 emission rating of 99 grammes
per kilometre (1,3 l/100 km 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 car manufacturer seeks to lift their position as a 'player' in the
production of sporty vehicles. 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.
