When Mercedes engineer Klaus Millerferli holds the suspension element for the new EQXX idea car in his arms you may assume one thing has gone improper with the design.
The steel half seems misshapen and unstructured, extra appropriate for the trash can than the entrance axle of a cutting-edge electrical car. It definitely doesn’t look sturdy sufficient to take the weight it must maintain.
But in actual fact Millerferli could be very happy with the element he’s holding, admiring its low weight and ethereal form. After all, it’s not solely extraordinarily secure, but in addition weighs 4kg lower than a standard element.
And the place did the inspiration come from for this uncommon design? Nature itself.

Skeletons made from carbon
“To obtain this, we designed it primarily based on nature’s mannequin,” the engineer says. The element was developed – or slightly grown – utilizing the identical software program used to generate monsters for laptop video games. That explains why it seems slightly like a skeleton.
The structural half is extraordinarily secure at the essential factors and doesn’t want extra materials wherever, making it significantly mild.

Mercedes is following a pattern that’s at the moment very talked-about amongst car designers. In the search for the lowest potential weight and the most electrical vary, they’re taking their inspiration from nature.
That is especially evident in the Mission R idea, Porsche’s try and create the electrical race car of the future.
Instead of setting up a body and then cladding it with a physique, the two-seater has a carbon skeleton. This so-called exoskeleton will not be solely significantly mild and secure, but in addition seems spectacular, in line with Porsche designer Peter Varga.
Turtle shell, dinosaur cranium
Other firms have explored this concept already. The Edag engineering group created an idea car modelled on a turtle shell whereas the Fraunhofer Institute for Manufacturing Engineering and Automation (Ipa) in Stuttgart created a sporty two-seater that weighs lower than 500kg and has a physique impressed by a Simosaurus dinosaur cranium.

In addition to light-weight development and security, designs taken from nature are additionally aerodynamically environment friendly.
“Because relating to circulation resistance, evolution has already produced some sensational shapes,” says Teddy Woll, who’s accountable for the wind tunnel at car maker Daimler.
However, there are limits to what could be achieved, particularly when there is a battle between aerodynamics and aesthetics, Woll admits.
For instance, Mercedes Benz created an idea car in 2005 that was impressed by the form of a boxfish. The design was very streamlined and tremendously environment friendly, however unlikely to enchantment to the public.

Imitating the lotus blossom
Of course bionics – or biologically impressed engineering – has been round for a very long time. Whether it is automobiles, aviation or family know-how, nature has been offering the mannequin for human creations since time immemorial.
One of the hottest examples of the switch of designs from nature to the manufacturing facility is the so-called lotus blossom impact, specifically the approach that the leaves of the lotus plant defend themselves towards filth.
It’s a property that paint producers hope will quickly make car washes out of date and which tyre producers assume will hold the sidewalls of their tyres clear.
It’s not simply flowers that encourage researchers. BMW took a detailed have a look at the pores and skin of the shark to see the way it reduces frictional resistance.
The concept was that if the identical profile was transferred to a movie and then glued to a car’s bodywork, gasoline consumption could possibly be lowered.
BMW didn’t pursue that concept any additional, however the car maker continues to look for options to new technological challenges utilizing bionics.
“Bionics gives fascinating inspiration and approaches to options,” says BMW spokesperson Julia Jung. – dpa/Thomas Geiger
