[2] Airbus "envision[s] Vahana being used by everyday commuters as a cost-comparable replacement for short-range urban transportation like cars or trains".

It was being developed at A³ (A-cubed), the expanded project and partnership outpost of Airbus in Silicon Valley.

[5] Airbus said "Our work on this demonstrator confirms our belief that fully autonomous vehicles will allow us to achieve the scale required of Urban Air Mobility.

"[7] To test the Vahana concept, small models flew in Santa Clara, USA in 2017.

In June 2017 at the Paris Air Show the prototype Vahana Alpha One (registration N301VX) was publicly presented for the first time.

[11] By January 2019, the second aircraft, Alpha Two, was completed, while the first was testing transitions to forward flight, but was not yet flown with the wings horizontal.

For both configurations the hover performance estimates were based on blade element momentum theory.
