Motor Development International SA (MDI) is a Luxembourg company.  Its centre of research & development is based in Carros, France through MDI’s subsidiary company CQFD Air Solution.

Established by Guy Nègre, MDI has developed an environmentally friendly compressed air motor. The compressed air motors available today can replace all existing motors and cater for any kind of application.

Guy Nègre died in June 2015. His son Cyril Nègre is President of MDI.


AFL has been in close relationship with MDI since 1999 plus an investor – generating many benefits.

Air Future Group (AFG) in Australasia is a strategic partner with  MDI SA who are the world leader in compressed air electric vehicles,  electricity generation and renewable energy storage.

MDI energy storage provides substantial benefits over chemical and other batteries. Their electric vehicles provide benefits and attractiveness for mass user uptake. MDI manufacturing is distributed and modular and very flexible.

AFL & MDI have a top management and technical team spanning Australasia and Europe, working together to provide both turnkey regional commercialisation and production.

It has taken two decades for MDI to progress through its research and development, move to industrialisation, and now be mass commercialising.

There is now a huge tailwind for MDI’s technology and product capabilities.
