Is this the ultimate improvement in suspension? It would make a high-speed bus ultimately comfortable. Today there might be a disadvantage of road transportation compared to rail, particularly at high speeds, because roads are usually rougher than railways.
About this suspension is said on its website, that it consumes as much energy as an air condition. Naturally, lifting the vehicle up and down by linear motors consumes energy, and I presume the energy consumed increases with both the weight of the vehicle and the roughness of the road.
Furthermore, the German Wikipedia-Artikel about linear motors mentions a maximum achieved force of 30 kN. I don’t know if this figure is applicable for this case, but if it was, it might restrict the use of the Bose suspension to axles with a low weight and make it unsuitable for heavy-duty vehicles.
