The Mercedes-Benz bionic car study will have its world premiere at this years DaimlerChrysler Innovation Symposium in Washington.<br>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.<p>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.<p>In order to use this great potential for automobile development purposes, specialists at DaimlerChrysler first created a 1:4 car model whose shape was substantially based on the boxfish. During tests in the wind tunnel, a drag coefficient of 0.095  a previously unprecedented value in automotive engineering  was measured for this clay model. It corresponds to the values achieved with highly streamlined shapes (Cd 0.09) and other aerodynamically ideal forms.<p>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.<p>20 percent lower fuel consumption and up to 80 percent lower nitrogen oxide emissions<p>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. In accordance with the US measuring method (FTP 75) the range is around 70 miles per US gallon (combined), which is about 30 percent more than for a standard-production car. At a constant speed of 90 km/h the direct-injection diesel unit consumes only 2.8 litres per 100 kilometres corresponding to a range of 84 miles per gallon in the US test cycle.<p>DaimlerChrysler is currently testing its SCR technology worldwide. By this means, and with the additional operating fluid "AdBlue", the nitrogen oxide emissions of the direct-injection diesel engine can be reduced by up to 80 percent. The aim of these trials is to avoid the fuel consumption disadvantages by optimising the in-engine combustion processes. This is where Mercedes-Benz car engineers are benefiting from the experience gained by their colleagues in the commercial vehicle sector, where SCR technology is already in successful use. DaimlerChrysler also intends to use the great potential of this process for diesel passenger cars in future, and will initially be offering SCR technology in the USA when the trials have been completed.<p>"AdBlue" is an aqueous urea solution which is sprayed into the exhaust system in precisely metered quantities, depending on the engine operating status. This converts the nitrogen oxides into harmless nitrogen and water. The reservoir for this service fluid is located in the spare wheel recess of the concept car, and its capacity is sufficient for a mileage corresponding to the service interval for a current Mercedes diesel model. The Mercedes-Benz bionic car study is also equipped with a maintenance-free diesel particulate filter.<p>Great rigidity and low weight  a growth principle designed by nature<p>The boxfish, the aerodynamic model for the concept car, is also a prime example of rigidity and light weight. Its skin consists of numerous hexagonal, bony plates which provide maximum strength with minimal weight and effectively protect the animal from injury.<p>DaimlerChrysler researchers examined this bionic structure and transferred this principle to the Mercedes-Benz bionic car study with the help of a special calculation process. The process is based on the principles of bone formation and for instance allows up to 40 percent more rigidity to be achieved in the external door panelling than would be possible with conventional designs. If the entire bodyshell is calculated according to this bionic principle, the total weight is reduced by around one third with undiminished strength and crash safety.<p>(Source: DC)

Fuell efficiency is very good, but can you also have it in a car that's not gonna make you sick by just looking at it. <br>

They could have chosen a better looking fish... but the structure itself is strangely cool <A HREF="http://www.auto-motor-sport-online.de/d/84400" TARGET="_blank">http://www.auto-motor-sport-online.de/d/84400</A>

AM2, I was thinking more of the 2 door C4 for the rear. Apparentely the car could meet US emission standards:<p><A HREF="http://www.autoweek.com/news.cms?newsId=102542" TARGET="_blank">http://www.autoweek.com/news.cms?newsId=102542</A><p>I serioursly hope the german firms bring in diesels back to NA, if not only then Canada. <IMG NAME="icon" SRC="http://www.germancarfans.com/images/forums/biggrin.gif" BORDER="0"> <p>Is the picture of the outer structure real?

This car's design based from that fish is only around here in sydney <IMG NAME="icon" SRC="http://www.germancarfans.com/images/forums/biggrin.gif" BORDER="0"> , according to today's 'the daliy telegraph'. I'm very sure people from mercedes benz watched Finding Nemo movie.

Fuel economywise, this car does nothing breathe taking. The much better looking Audi A2 3L achieved 2.99l/100km compared to this cars 4.3L/100km (well the A2 achieves 3.3L/100k with A/C which is still 1L better than this concept). Why do I compare it to the A2? It sits only 4 just like the A2 despite its much larger size.<p>One might argue that the A2 had only 61hp compared to the Bionic car's 140hp. The A2 achieved acceleartion from 0-60mph in 13.8s which is still good.<p>Then another would ask; why are my doing this comparison? Simple, I don't fancy this type of concepts. It doesn't improve on what has already been achieved( many diesel superminis achieve 4.3L/100km in combined driving and some even do better) only the really impressive cdx of 0.19( considering its spaciousness) and it won't go into production while the overachieving A2 did. <p>This maybe regarded as pure mindless bashing, but I expected more than this. The car is just a PR exercise and its damn Ugly while doing it.<p>If by any chance that car goes to a show stand at any autoshow, They should keep people far from it to stop show goers from puking on it.

It is kind of hard to compare fueleconomies without knowing what kind of construction the car uses.. I mean A2 might be economic during its operating years.. but it doesn't negate the fact that automotive grade Al is very energy intensive to purify and to manufacture.. <p>Remember aerodynamic capability is only part of the equation.. the other is weight.<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>taskbearer</b> &raquo;</i></TD></TR><TR><TD CLASS="quote">Fuel economywise, this car does nothing breathe taking.

so this dcx car is based on a boxfish, and i guess the prowler was based on what? a hammerhead?
