Bild-small-bw1Bild-small-1Last year's Michelin Design Challenge was the first time for me in participating on an international design contest. The design challenge addressed lightweight vehicle design, which had to be production feasible. Followed you will find detailed facts on the design concept and concept pictures.


How does the design answers the anticipated preferences, lifestyles and transportation needs for the people in your country or region?

Bild-small-bw2Bild-small-2Modern customers are eagerly seeking for transportation solutions which not only provide aesthetic design in combination with appropriate material choice for appropriate haptics, comfort and advanced driving dynamics. Customer demands in terms of eco-efficiency, affordability and safety are progressively in focus, not only in metropolitan areas across Europe.
Milo is an original design concept which represents a radical approach to fulfill present and future demands of eco-efficiency, driving comfort and safety of passengers for urban mass mobility. Because of the unique compactness beyond reach for a car of its class, Milo transports up to six adults inclusive luggage.
Milo is equipped with a compact 17“-wheel, which contains a resource efficient wheel hub engine design with integrated torque and servo motors for driving and steering functions and an intelligent shock absorbing high-tech low profile tire.
This next step in the evolution of tire technology will increases the driving comfort and noise damping while rolling over cobblestones or roads in bad condition. Further, the equipped electric drive solution, which combines propulsion and steering integrative within a compact wheel hub engine design, will provide a highly flexible asynchronous all wheel drive.
Further, by holistically using composite materials with continuous aramid and natural filaments, which are woven in direction of drive loadings, total weight of Milo’s bodywork will be decreased by more than 60% while mechanical properties will be increased.
Both key technologies, the integrative power train solution as well as the lightweight bodywork design, will support Milo with the necessary ability to perform turning circles similar to motor bikes combined with safety attributes of a conventional SUV and acceleration ability of a roadster. Hence quality and joy of driving will be times ahead of state-of-the-art family vehicles.
Especially this makes Milo to be the perfect multi-passenger vehicle for tight metropolis like Prague, New York, Tokio etc..


What makes your design unique?

Bild-small-bw3Bild-small-3The Milo design approach combines an aesthetic body design with an innovative power train and steering solution within a wheel hub engine as well as a holistic usage of modern lightweight multi-material composites and a novel impact protection fabric. The addressed design approach is driven by technological and economical feasibility. Exactly this will enable Milo to be the next game changer concerning sustainability and resource efficiency for urban mass mobility.


What technologies, innovations, lifestyle needs and concepts have you incorporated into your design? How?

Bild-small-bw4Bild-small-4Milo’s compact 17“ wheel contains a resource efficient wheel hub engine design with integrated torque and servo motors for driving and steering functions and an intelligent shock absorbing high-tech low profile tire by Michelin.
The torque motors for propulsion, each 40 kW, are triggered independently by Milo’s real-time power electronics. This highly flexible asynchronous all wheel drive ensures best traction and adapts appropriately the rotation speed of each wheel while cornering to reduce yarn slipperage or friction. Hence, rotation is transmitted nearly without performance loss to the ground.
Within the main frame of the spoke a 3.6 kW servo motor is integrated. Due to its high moment of torsion and its centric point of revolution within the housing of the stator unit, the wheel system needs only minimal space while range of steering is optimized.
To improve shape stability on elevated cruising speeds and resistance against axial torsion while cornering, belt, carcass and side wall of Milo’s tires are reinforced with continuous aramid filaments placed in direction of main loadings.
Further, Milo’s low-profile tire contains an inlay made of a unique shear thickening non-Newtonian fluid (D3O). In its raw state this smart fabric flows freely when moved slowly, but on shock, locks together to absorb and disperse energy, before instantly returning to its flexible state. In detail, in case of outer loadings, the intelligent molecules within this synthetic elastomeric polymer lock together while shear viscosity increases. Hence transmitted forces to inner structures will be absorbed significantly. Especially this increases the driving comfort and noise damping while rolling over cobblestones or roads in bad condition.
