A century ago, aviation pioneer Glenn Curtiss debuted the Autoplane, a three-seat car-cum-aircraft with removable wings.2 Ever since, automobile and aviation enthusiasts have been dreaming of “flying cars.” Flying can replace driving in cities around the globe, saving people's time as trips that take hours on the ground can be reduced to minutes in the air, improving productivity and quality of life. After decades of failed projects and false starts, we may now be on the threshold of this vision becoming a practical reality.
This new class of vehicles is emerging in the midst of an already dramatic transformation in the way people and goods move around. Driven by a series of technological and social trends, from ridesharing and bikesharing to electric and autonomous vehicles and beyond, the future of mobility could ultimately create a more integrated transportation system that is faster, cheaper, cleaner, and safer than today’s.3 Even as players across a host of industries come to grips with these changes to terrestrial mobility, advances in flying cars could add, literally, an entirely new dimension to an already complex landscape.
Even as players across a host of industries come to grips with these changes to terrestrial mobility, advances in flying cars could add, literally, an entirely new dimension to an already complex landscape.
While we are early in this journey, market segments seem to be forming, some early entrants are experimenting, regulations are being formulated, and technology is developing. This study looks at the emerging market for personal mobility, exploring both the current state of the technology—including the rapid advances made in recent years—as well as the many hurdles that remain before flying cars become widely adopted. It also examines important questions related to the regulatory framework and supporting infrastructure. Finally, the study explores how widespread use of passenger drones could reshape urban mobility, and suggests some key steps players in aerospace and other industries can do now to prepare for this exciting possibility, as well as what disruptions to possibly expect.
This study’s findings are based on both primary and secondary research. As part of our research, we interviewed subject matter experts and senior executives at leading aerospace and automotive companies as well as start-ups that are involved in the development of passenger drones and flying cars.
The technology and product development of passenger drones and traditional flying cars seem to be swiftly progressing. These vehicle concepts have been under development since the 1980s, and various prototypes already exist, with the majority capable of vertical takeoff and landing (VTOL). A VTOL vehicle is an aircraft that takes off, hovers, and lands vertically and does not require runways. For this study, our definition of VTOL excludes any type of helicopter. While traditional helicopters have had this capability since their inception, most are considered highly energy inefficient, seeming to prevent large-scale operations. Many companies today are instead focusing on electric or hybrid-electric designs with VTOL capabilities. These vehicles, popularly called flying cars or passenger drones, are designed to accommodate around two to five passengers or the equivalent cargo weight; be highly energy efficient, with reduced or zero emissions; and be substantially quieter than a traditional helicopter.4
Figure 1 lists and compares some of the major flying car and passenger drone manufacturers and their proposed vehicles.
With the increasing popularity of small unmanned aerial vehicles or drones, and regulations increasingly supporting their commercial use, passenger drones and flying cars appear to be moving closer to reality, with aerospace and aircraft design technology being developed rapidly. Many passenger drone and flying car manufacturers have already passed the conceptualization/design phase, and a majority of them are currently in the prototyping and testing stage, with most manufacturers expecting delivery by 2020 (figure 2).
In terms of technology, the industry is at an advanced development phase, and if safety and regulatory hurdles are cleared, passenger drones are expected to get wings by 2018–2020, and traditional flying cars by 2020–2022, while revolutionary vehicles could be a reality only by 2025.5

China’s Ehang has already tested its self-flying passenger drone, named 184, which was showcased at the Consumer Electronics Show in 2016. This quadcopter has already been tested in Dubai, where it is expected to be operational as early as 2018, according to the company. However, Ehang still needs to obtain an aviation license.
Aurora Flight Sciences, acquired by Boeing in October 2017, unveiled the eVTOL, with the prototype tested in the beginning of 2017. The company also announced a partnership with Uber, which is working on on-demand flying cars. Aurora aims to deliver 50 aircraft to UberAir by 2020.
The final commercial design of Flying Car by AeroMobil was revealed in April 2017. The vehicle is designed to be both driven and flown, unlike those of other companies, which are mostly manufacturing VTOL aircraft. AeroMobil has started taking pre-orders, with deliveries anticipated to commence in 2020.
Airbus’s Project Vahana, an electric autonomous helicopter, and CityAirbus, an air taxi, are also in the advanced development stage. Project Vahana is designed for both passenger and cargo transport, and Airbus plans to conduct flight tests of the prototype by the end of 2017. CityAirbus is a design for an air taxi, with multiple propellers and the appearance of a small drone. Customers would be able to book a seat on CityAirbus as they book an Uber ride.
Volvo’s parent company, Geely, acquired a flying car start-up, Terrafugia, in November 2017. Terrafugia’s first flying car, Transition, is in its testing phase, with deliveries anticipated in 2019. The company is also working on a VTOL flying car, which is expected to debut in 2023.6
There are numerous potential applications for these new forms of urban mobility vehicles (table 1). For many of these, the airborne trip could be just one leg of a multimodal journey and potentially accessed via a single, integrated mobility-as-a-service interface.7 For example, a traveler could be picked up by a ride-hailing car from her home in the suburbs, driven to a nearby “vertiport,” and flown to another vertiport at the city’s edge, before taking the subway to her destination.
Despite the technological progress and many potential applications for these aircraft, there are various challenges to consider with respect to regulations, certifications, infrastructure, and air traffic management (figure 3). While possibly daunting, none of these challenges are insurmountable, and the aerospace and related industries have navigated similarly complex challenges before—not least of which is the development and deployment of commercial airplanes. The key could be close collaboration between regulators and private sector stakeholders across the extended mobility ecosystem.
From a regulation perspective, the Federal Aviation Administration (FAA), its equivalent agencies around the world, and other transportation-related regulatory agencies have to weigh in on the requirements for these piloted and autonomous passenger drones: Is a pilot’s license required? What airspace can they occupy? What are the vehicle airworthiness8 requirements? There is some progress as the FAA has already started discussing certification options with some manufacturers and believes that initially these vehicles should be manned, then autonomously assisted, and then converted to a fully autonomous aircraft at a later stage.9 While regulations related to piloted passenger drones and flying cars could be relatively easy to address, fully autonomous VTOL operations are likely to be more challenging, with issues around how to allocate the use of the airspace (lower altitudes to higher altitudes) considering the exponential growth in piloted and autonomous vehicles utilizing the airspace. Beyond the FAA, the US Department of Transportation and other agencies will likely have to consider autonomous cars; for now, regulatory agencies would need to focus on issuing nonbinding guidelines while avoiding binding regulation as the technology is still in flux.
Currently, national and local regulatory authorities are addressing regulations related to smaller drones. For example, in the United States, the FAA is considering extending commercial operations of drones over controlled airspace beyond visual line of sight.10 These advancements could be a starting point for regulations related to passenger drones and flying cars, and, ultimately, for revolutionary vehicles.
In terms of technology, there are various considerations for VTOL manufacturers. First, in a GPS-denied environment, these vehicles would need on-board sensors such as radar, optics, and geolocation sensors. While these technologies exist and are being utilized in autonomous cars, they would have to be improved to provide the longer-range sensing and recognition capabilities required to deal with the multidirectional and convergence speeds associated with autonomous flight. Second, these vehicles would require advanced technologies, such as artificial intelligence and cognitive systems, to enable advanced detect-and-avoid capabilities. Machine learning could be essential as operations move from piloted to autonomous: A vehicle would need to learn from the pilot’s actions over thousands of operational hours to become fully autonomous over time. Third, energy management is crucial: carrying an energy load sufficient to transport passengers or cargo, maintain a safety margin, and reload for the next flight. While battery technology is rapidly improving, in order to increase passenger and cargo capacity and extend the ranges of passenger drones, it will need to improve further, or alternatives would need to be found.
Infrastructure constraints include proper takeoff and landing zones, and parking and battery charging stations. A wide network of vertiports would require either new infrastructure or existing infrastructure, such as helipads, rooftops of large public buildings, and unused land, to be modified. To create a truly unified traffic management system, additional infrastructure may need to be installed along predefined flight corridors to aid high-speed data communications and geolocation. All these infrastructure changes would require the collaboration of commercial stakeholders and the local urban planning authorities.
There would have to be a robust air traffic management system in place to guarantee safe and efficient operations of passenger drones and flying cars, which would meet the requirements of the FAA and the European Aviation Safety Agency. To achieve this, industry leaders and manufacturers would likely need to reach an agreement on a reliable traffic management framework that integrates with other modes of transport, especially in urban areas. In the United States, there is already progress, with Uber and NASA recently signing a Space Act Agreement for traffic management of autonomous vehicles that will fly at a low altitude.11
For the scaled adoption of passenger drones and flying cars (particularly fully autonomous) to occur, the operators of these vehicles would likely need to demonstrate a near-flawless safety record, covering both mechanical integrity as well as safe operations. As we have seen with autonomous cars, any mishap can garner significant attention and can slow the pace of adoption.12 While achieving mechanical integrity would be easier, the operations of VTOL in suburban and urban areas could pose unique challenges—some of which are described in the aforementioned infrastructure section.
Apart from other considerations, people also need to overcome any psychological barriers they may have associated with the idea of flying in a pilotless aircraft, since these vehicles are likely to be autonomous eventually. According to a recent survey by UBS, a Swiss global financial services company, 54 percent of the respondents said they were unlikely to take a pilotless flight.13
Furthermore, for passenger drones and flying cars to be widely accepted, they would likely have to be both ubiquitous and as versatile as an automobile—people should be able to fly the vehicle to a store or take it to the beach, and it should be able to cover longer distances safely. Psychological barriers can be overcome if manufacturers and regulatory authorities ensure these vehicles are as safe as an aircraft, and the vehicles have well-documented safety records.

In 2013, Amazon hosted a 60-minute demonstration of its ambitious drone delivery program, Amazon Prime Air. Four years later, the program is yet to take off on a commercial scale. However, a drone delivering anything from your online shopping packages to medicines or even food may not be such a far-fetched idea. Several other companies such as Google and Alibaba have since launched their own R&D programs to make this a reality.
Over the past year, there have been various pilot programs featuring drones completing a successful delivery. In June 2017, Amazon patented a beehive-structured tower to serve as a multilevel fulfillment center from which its delivery drones can take off and land. Most of the drones for such programs are designed to take off and land vertically to transport even fragile goods with care, with a payload capacity of anywhere from 4 to 19 pounds.
However, there seem to be two key challenges slowing these drones from becoming a commercial reality. First, electric motor efficiency and battery capacity still need significant improvement, as the delivery radius of current technologies is only 10 miles from the warehouse. Since a company can have only a limited number of warehouses, it appears that drone delivery, even if it becomes a reality, for now may be limited to shorter distances—although companies such as Amazon and UPS have started using delivery trucks to serve as mobile warehouses, from where drones can be launched. UPS has already tested launching a drone from a delivery truck to distribute a package to the destination.
Second, the FAA in the United States and similar government bodies in other countries currently restrict drone usage due to a requirement for line-of-sight control, which means that a drone operator must be able to see (if not control) the drone first-hand throughout an entire flight. This safety requirement is focused on trying to avoid possible collisions with airplanes, power lines, and people and property on the ground. While such regulations are expected to be eventually lifted, the governments of some countries, such as China, have approved such drones.
As package delivery drones make their way to commercialization, passenger drones are expected to follow a similar development path.14
While widespread use of passenger drones and flying cars is likely decades away, their arrival could dramatically reshape a mobility landscape that is already in transition. And as we have seen in many other areas of disruptive technology—from driverless cars to streaming music to social media—being a “fast follower” can put companies at a disadvantage. It is still likely not too soon for businesses in multiple industries to consider developing a strategy for mobility’s third dimension.
So what opportunities for business does this create, and what disruptions can we expect? Multiple roles could potentially emerge:
These companies will strive to design, build, and scale the production of the VTOL aircraft. The potential demand for these vehicles might “correspond to about 100 times the yearly production of Airbus Helicopters,” according to Jörg Müller from the Airbus Group's corporate development department.15 The key success factors for these companies could be technology maturity and integration (as the basics of all the necessary technologies are already available) as well as the ability to get the aircraft designed and built, scale supply chain and production capacity, and to get an aircraft certified. These companies would derive their value through the manufacturing, selling, and leasing of the vehicles to a VTOL operator. Current trends include:
These companies would receive an on-demand request for VTOL transportation and dispatch it to the customer. It is unlikely that the rideshare model of today (driver owning the vehicle) will extend to elevated travel. Vehicles could be too expensive in the near term for individuals to own, pilots may need to be certified, and the maintenance and repair required to maintain a flight-worthiness rating would be extensive. The passenger drone operators may have to provision the fleet either by owning or leasing the vehicles, and be directly responsible for the full set of operational requirements, much like the on-demand executive jet market operates today.
While aerospace and technology companies have been the most active, a variety of other players could also try to cash in on the disruptive opportunities:
Other roles in the broader mobility ecosystem would also need to account for passenger drones. Mobility managers that provide seamless trip planning, ticketing, and payments would need to incorporate yet another mode into their consumer interface. Digital infrastructure would be key to ensuring safe, secure, and reliable communications between fleets of passenger aircraft. And we have already discussed the need to develop and maintain the requisite physical infrastructure.
Urban travel seems to become more difficult every day. Drivers can spend between 50 and 100 hours per year stuck in traffic in the most congested cities.22 In the United States alone, the direct (fuel and time) and indirect (higher prices of goods due to freight vehicles being delayed) costs of congestion totaled nearly $300 billion in 2016.23 These challenges could be exacerbated by growing populations and rising urbanization over the coming decades.
In many places, there simply is no more physical space to build new surface transportation infrastructure, even if budgets allowed it. One potential solution is to harness the power of data and analytics to better balance transportation supply and demand, and increase efficiency. But another opportunity is to look up—utilizing the airspace above urban and suburban areas to move more people and goods.
While still nascent, this mode of travel represents a significant business opportunity for those that can design, build, operate, maintain, and deliver passenger drones, flying cars, and related services. It also affects other sectors:
A decade ago, driverless cars seemed a little more than a futurist’s vision. Today, nearly every automaker and many major technology companies are investing billions in their development, with many predicting their widespread availability near the turn of the decade. Likewise, flying cars may today seem like science fiction. Where will we be a decade from now?
