We've already been scolded this year not to call the air car the Air Car. The nomenclature is not getting any easier, but hopefully we've reached the last rebranding of the "Compressed Air Vehicle." An update to the MDI website tells us that the vehicle line up now has a "FlowAIR" theme. The models are now known as the OneFlowAIR (open top), MiniFlowAIR (a mini minivan) and CityFlowAIR (a truck-like vehicle with a bed). If you've been following the MDI story, you might recognize parts of these names from their previous incarnations as the OneCAT and MiniCAT.

An urban public transportation concept vehicle is now called the Multi FlowAIR and there is also the very odd looking AirPod, a concept that can be used to ferry people or goods in a little bubble. If outfitted for personal transportation, there are four seats - one in front for the driver, two adult seats looking backward and a seat for an infant somewhere, if I understand the French correctly.
