Chrysler is using a new concept vehicle to examine the great potential of bionics for automobile development
In designing the bionic car, engineers at Mercedes-Benz looked for an example in nature which not only approximated the idea of an aerodynamic, safe, comfortable and environmentally compatible car in terms of details, but as a formal and structural whole. The example arrived at was the boxfish.
Despite its boxy, cube-shaped body, this tropical fish is in fact outstandingly streamlined and therefore represents an aerodynamic ideal. With an accurately constructed model of the boxfish the engineers in Stuttgart were able to achieve a wind drag coefficient of just 0.06 in the wind tunnel.
DaimlerChrysler utilised the findings from this research during the development of the Mercedes-Benz bionic car, a fully functioning and roadworthy compact car with a length of 4.24 metres and space for four occupants plus luggage. With a Cd value of just 0.19, this concept vehicle is among the most aerodynamically efficient in this size category.
In addition to superb aerodynamics and a lightweight construction concept derived from nature, the 140-hp diesel engine and innovative SCR technology (Selective Catalytic Reduction) greatly contribute to fuel economy and a further reduction in exhaust emissions. In the EU driving cycle the concept car has a fuel consumption of 65.7 mpg.
Bionics – a combination of biology and technology – is a quite recent field of research which has nonetheless already made remarkable progress possible in different areas. Nature has provided many ideas for high-strength materials, low-friction surfaces and dirt-repellent coatings.
