The concept

The Paspartu (see video) is an eco-friendly six-wheel drive amphibious ATV that that can adapt its tire width and air pressure to minimize its impact on fauna and flora. It’s a tribute to my uncle, Germain Bombardier, who developed and built an amphibious carrier back in the 60’s. Germain and his father (J-A) nicknamed it the ‘Passe-Partout’.

The background

I recently worked with Juan Garcia Mansilla on a very light vehicle concept capable of travelling over dense forests (view the Canopi). One major challenge consisted in minimizing the impact on the leaves and branches. While discussing this with one of my collaborators, Olivier Peraldi, he suggested that I create a variation capable of travelling over water. In a nutshell, this is how the Paspartu concept originated.

How It works

The Paspartu would be powered by a quiet 100hp hydrogen fuel cell. Ideally, the vehicle would feature six lightweight electric motors, each capable of driving its own wheel and modifying torque and speed depending on the driving conditions.

The most interesting part is that the wheels and tires who would be able to expand by increasing their width. This would permit the riders to reduce the surface pressure on the ground, modify energy consumption, and even reduce noise levels. The Paspartu would be designed to easily cross various densities of mud and sensitive areas, covered with living plants, whilst reducing damage to a minimum.

The tire’s air pressure could also be modified in each wheel depending on the surface that needed to be crossed or the speed at which the driver needed to travel. The idea here is to optimize the wheel’s characteristics (width, diameter, and internal pressure) depending on the situation.

Since noise varies based on the tire’s contact with the ground and its stiffness, it would be possible to have a noise reduction switch in the dashboard that could change the characteristics of the vehicle to make it quieter.

What it’s used for

The Paspartu could be used as an exploration vehicle capable of moving through most terrains. It would float well enough to carry two passengers and their equipment. It could be used by explorers, scientist, hunters, surveyors, land owners, etc. I think there would be an added value if we could modify the vehicle’s wheel width and air pressure on the fly.


The Paspartu concept was developed in December 2015 by Charles Bombardier in collaboration with Juan Garcia Mansilla, an Industrial Designer from Argentina. He graduated from the University of Buenos Aires in 2012. Juan currently works as a senior designer at a product design firm and as a freelancer. Juan also created the design of the Canopi tree crossing vehicle and the Trident jet boat concept.
