Webster’s definition of “sacrilege” includes “gross irreverence toward a hallowed person, place or thing.” I submit that making a four wheel vehicle handle like a motorcycle, and provide the same sensations, will be considered sacrilege by many of our readers. Nonetheless, the Quadro 4D is more than an interesting concept, it is a working prototype of a production vehicle that will be on sale late next year. Developed by the Italian firm Marabese Design, it incorporates some of the technology already available in the Piaggio MP3. Like countless other motorcycles and scooters, the Piaggio MP3 was designed by Marabese Design.
Marabese has developed a new branch that it calls Quadro Technologie, whose web site you can visit here, which is developing both the Quadro 4D and the Quadro 3D (very much like the existing Piaggio MP3 with two wheels in front and one in the back). The amazing ability to articulate each wheel separately and lean the 4D like a motorcycle derives from patented technology, including the Hydraulic Tilting System (HTS). We have tested the Piaggio MP3 here. We enjoyed the experience, and can vouch for the incredible feeling of confidence in the front end provided by the two wheels. The 4D looks even more amazing, as you can see in the following video.
