In 1996, Dieter and his colleagues from the Mercedes Center in Sindelfingen, Germany, looking for a model for a holistically bionic car, respecting at physics, design, and aerodynamics. So he to Ronald Fricke, head of the department at the Rosenstein Museum in with its huge collection of fish.

They were thinking a bionic car and. fish for it, Fricke recalls. The team’s instincts were to use streamlined penguins, dolphins, and tunas. But on a to the museum, it became clear their ideas of tunas and were not useful to design which contain a cubicle for while swiftly-swimming fishes are Fricke says. It was our idea to a slowly but steadily swimming and the boxfish was the first option.

The found in coral reefs, has structural strength but low mass. the ungainly appearance of the fish, it has extremely low flow resistance, a drag coefficient of an incredible For comparison, a penguin flying water is considered extremely with a coefficient of 0.19. streamlined, lower-drag fish do but they are not as rigid or maneuverable as the nor do they have a relatively cross section.

Boxfishes interest biologists they have very morphologies from most fish, yet they are highly according to Ian Bartol, an American researcher at Virginia’s Old Dominion His work is funded by the Office of Research, which is interested in more energy-efficient and stable vehicles.

From an applied says Bartol, locomotive on boxfish can be used by engineers and who are interested in biomimetic solutions to control, maneuverability, and even reduction. He points out the trade-off found in both nature and design) between stability and The boxfish displays both. The arises from the unique generated by body shape and as does enhanced propulsion.

Fricke and his colleagues created a Ostracion meleagris model, they gave to DaimlerChrysler. The boxfish was chosen, according to because males have a on their head, not useful for a and besides, the females are stouter, is good for a car shape. As the company working on a prototype, it became that the boxfish had an excellent shape, and even the car prototype was in the top Fricke notes, Cars have some [aerodynamic] compared to fish. For example, have to have windshield and wheels. Also, the snout was for aesthetic reasons. and on the surface of the it wasn’t possible to take for now, of the star-like structure of the which add to aerodynamics and stability. No surface structures are possible in the

The resulting concept car, in June 2005 at a Washington, DC, is a complete transfer from to technology, Mercede’s Thomas says. The boxfish has to move as little energy consumption as withstand high pressures, and its body in collisions. and move in confined spaces. [while] its anatomy is nearly identical to the of a car body. The car’s drag is equal to that of a penguin. By a car with a coefficient of 0.26 is very well designed,

After the prototype was completed, the team returned to the museum to see morphology in greater detail. we dissected a boxfish specimen, says, we found an interesting mechanism close to the gill apparently to cool down the temperature within the box of the boxfish. The didn’t use this exchange in the prototype, but it’s an important for future applications, because the openings are very small to the cooling openings in cars, but very effective.

It’s that Mercedes-Benz has used the but understandable, because it expresses so the design constraints of a car: low drag, and a big cross-section, says who adds that the concept car is a example of how some of nature’s together with human and creativity can help advance There was one element of the boxfish’s that really impressed a three-pointed star on each of its plates, which just so to resemble Mercedes’ famous However, Fricke laughs, didn’t use that, some are just too unfamiliar.
