Solar Impulse 2 inizierà il suo giro del mondo fra fine febbraio e inizio marzo e volerà per 25 giorni ripartiti su 5 mesi, percorrendo 35'000 chilometri a una velocità compresa fra i 50 e i 100 km/h. L'aereo a energia solare, capace di volare "di giorno e di notte senza carburante", decollerà da Abu Dhabi e farà la prima tappa a Muscat, in Oman. Quindi punterà verso India (Varanasi e Ahmedabad), Myanmar (Mandalay), Cina (Chongqing e Nanchino), Hawaii e Stati Uniti (Phoenix, New York e una terza fermata da stabilire in funzione della meteo).
L'ultima tappa del viaggio comporterà la traversata dell'Atlantico e un ulteriore scalo nell'Africa settentrionale o nell'Europa meridionale. L'arrivo ad Abu Dhabi, dove il velivolo è stato trasportato da Payerne il 6 gennaio in pezzi stivati in un Boeing, è previsto per la fine di luglio o l'inizio di agosto.
L'impresa coronerà un progetto che ha comportato 12 anni di studi e in cui sono già stati investiti 150 milioni di franchi.
