The Future of Advanced Air Mobility

South Korea's Hyundai unveiled its S-A1 eVTOL personal air vehicle program on January 7, 2020, at the Consumer Electronics Show in Las Vegas. At the same time, rideshare group Uber announced that the car manufacturer is now a partner in its plans to launch an air-taxi network called Uber Air.

Hyundai's engineering team aims to have a full-scale prototype ready to start test flights in 2023, with the company targeting type certification in 2028. The four-seat aircraft will initially be piloted, but might subsequently fly autonomously, at which point passenger capacity could increase to six. The all-electric S-A1 is expected to be able to fly up to around 60 miles (100 km) at speeds of up to 180 mph (290 km/h) while cruising at between 1,000 and 2,000 feet. A key design goal, as per Uber's specifications, is for the aircraft to be able to be fully recharged within five to seven minutes.


Our objective assessment of this program’s probable success.

FutureFlight assesses the probability of success for a new aircraft program by considering the following criteria:

  • Total investment funds available in proportion to the anticipated cost of getting an aircraft certified and in service
  • A company’s in-house capability (in terms of numbers of engineers, technical staff, and customer support teams)
  • The past experience of the company and its senior leadership in developing aircraft
  • The caliber and past experience of key program partners
  • Whether key aircraft systems have been selected and are available for use
  • Whether the preliminary design review has been completed
  • Whether the design for the full-scale prototype has been completed
  • Whether the type certification process has been formally initiated with an appropriate regulator
  • Whether the company has achieved a first flight with a full-scale prototype
  • The number of hours logged in a flight test program
  • Whether type certification has been achieved
  • The number of orders and commitment received for the aircraft
  • Whether the company has adequate facilities to begin series production of the aircraft
Our Methodology

Hyundai has committed $1 .5 billion to the S-A1 program, as part of a much larger $52 billion bet on electric vehicles and "disruptive mobility technology." The company has no direct experience of aerospace technology but is in the process of significantly ramping up its engineering capability. According to Uber, the automobile manufacturer's long experience in lean manufacturing will allow it to build the planned eVTOL aircraft at a significantly lower cost than most rivals. 

However, as of January 2020, it had yet to define the design for the S-A1's propulsion system and it clearly has a lot of work to do to complete the design and build a full-scale prototype by 2023.
