DaimlerChrysler is using a new concept vehicle to examine the potential of bionics for automobile development, and has achieved outstanding results for fuel consumption and emissions with a combination of pioneering diesel engine technology and innovative emission control methods. The Mercedes-Benz bionic car study will have its world premiere at this year’s DaimlerChrysler Innovation Symposium in Washington.  

To realise the Mercedes-Benz bionic car, the engineers at the Mercedes-Benz Technology Centre and the DaimlerChrysler Research department have for the first time looked for a specific example in nature which not only approximates to 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 103 kW/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 4.3 litres per 100 kilometres – 20 less than a comparable series-production car.
