Their backgrounds vary, but each believes they can lead the personal flight revolution
Just a few years ago, the idea of hailing an electric, autonomous flying vehicle via a smartphone app, like a car from Uber or Lyft, then have it whisk you over congested city streets, dropping you at your destination a few minutes later, sounded like pure science fiction.
But what was once considered preposterous is edging closer to reality, as companies large and small, new and old, race to be the first. Startups like Lilium are competing against aviation giants like Boeing and Airbus, as well as car makers like Audi and Aston Martin. But, with obvious parallels with the dream of a fully autonomous car, claims of the flying car being just a few years away are starting to repeat themselves, and some early pioneers have gone quiet.
Here is a quick look, updated in December 2020, at the biggest players in the industry, and the vehicles they hope will unlock a whole new transportation sector – one which Morgan Stanley claimed in 2018 could be worth $1.5 trillion a year by 2040.
Perhaps the most high-profile startup in the air taxi industry, Lilium was founded in Germany in 2015 and is working on an aircraft called the Jet. In its latest guise, shown off in May 2019, the Jet is powered by 36 electric motors and can fly as far as 300 km (186 miles) in as little as 60 minutes.
It is hoped the aircraft will be used to replace cross-city taxi journeys, with Lilium claiming it will eventually cost about the same, as a taxi, but complete journeys four times as quickly. The Lilium aircraft has been designed by renowned automotive designer Frank Stephenson, who was responsible for the new BMW-owned Mini Cooper, the current Fiat 500, the Ferrari F430 and the McLaren P1, among others.
Like many of the aircraft featured in this article, the Lilium Jet is a VTOL, which stands for vertical takeoff and landing. It can do this because its rotors rotate, pointing down while taking off and landing, and backwards when flying.
Still very much full-steam ahead, Lilium said in January 2020 how it is working to have its Key vehicle certified with regulators and authorities like the FAA. In November 2020 the company announced plans to build a $25 million, 56,000-square-foot 'vertiporm' hub for its electric aircraft in Orlando, Florida. The company reiterated its plans to begin public flights in 2025.
Uber chief executive Dara Khosrowshahi said in early 2018 that he believes flying cars will be commercially available in the US within the next ten years.
Not to be confused with helicopters, the vehicles Uber and others have in mind more closely resemble drones. A capsule large enough for two or three passengers - plus a pilot, at least initially - is flown through the air by a number of downward-facing propellers, powered by electric motors.
Khosrowshahi has previously said how flying autonomous vehicles make more sense than driverless cars when it comes to relieving pressure from congested city streets. Additionally, flying vehicles do not have to deal with the complexities of gridlocked roads, complicated junctions and unpredictable pedestrians.
On December 2, 2020 it was reported by Axios that Uber was in advanced talks to sell its Uber Elevate division to Joby Aviation, a California-based startup that had previously planned to partner with Uber on its flying taxi business. It was reported that a deal could be announced before the end of 2020, as Uber looks to recover from a tough year that saw riders of its taxi service fall dramatically during the Covid-19 pandemic.
Chinese company Ehang caused a stir when it unveiled a huge drone at the CES technology show in early 2016. Looking similar to the kind of drone you might buy in Walmart, the electric Ehang 184 was actually designed to carry humans. The company said the drone would cost between $200,000 and $300,000, and be capable of carrying a single passenger weighing up to 260 pounds for 23 minutes.
Soon after, Dubai expressed interest in bringing the drones to its skies, where they could autonomously shuttle tourists for around 20 minutes at a time, beating the city traffic below.
The Ehang 184 completed its first human test flights in rural China in February 2018, after which the company said the drone can fly safely at up to 130 km/h (80 mph) "in force seven typhoon conditions."
In November 2020, Ehang's drone took to the skies in South Korea as part of a tour of Seoul, Daegu and Jeju Island to signify the starting point of the exploration of urban air mobility (UAM) by South Korea. During the demonstrating, Ehang showed how its vehicle could be used to transport passengers, but also work as part of an emergency medical service, and offer aerial sightseeing for tourists.
Not to be confused with the luxury car maker of the same name (they used to be the same company), Rolls-Royce the engine manufacturer wants to join the flying taxi party. The company revealed concept images of a 250 mph flying machine in 2018 with a claimed range of 500 miles – far greater than most of its rivals.
The concept is designed to carry four or five people, and its wings can rotate 90 degrees to enable vertical take-off and landing. Instead of batteries, the Rolls-Royce air taxi is designed to be powered by gas turbines, which produce electricity that drives six electric propulsors.
Rolls-Royce said in 2018: "We believe that given the work we are doing today to develop hybrid electric propulsion capabilities, this model could be available by the early to mid 2020s, provided that a viable commercial model for its introduction can be created."
The company hasn't said a great deal about this concept vehicle since, but maintains an Air Taxi section of its website, explaining its plans for providing electric and hybrid-electric propulsion systems for flying taxis built by others. One dish concept is the CityAirbus demonstrator, built in collaboration with Airbus and designed to carry four passengers at up to 75 mph. The vehicle had its first untethered test flight in December 2019.
The air taxi industry is not just a playground for blue-sky-thinking startups seeking investor cash. Aircraft giant Boeing is also in the race with what it calls a PAV, or passenger air vehicle. The vehicle completed its first test flight in January 2019 at an airfield in Manassas, Virginia.
Boeing says the electric aircraft will eventually fly fully autonomously with no pilot at the controls, and cover a range of 50 miles before needing its batteries charging.
Boeing's efforts took off in 2017 when it acquired Aurora Flight Sciences, a company which is helping Uber with the development of its own flying vehicles.
The Boeing aircraft is 30 feet long, has a wingspan of 28 feet, and is a combination of helicopter, drone and fixed-wing airplane. The company is looking to build two versions initially, one capable of carrying two passengers and one for four people. A third version designed to carry freight weighing up to 500 pounds will follow after, assuming they are a technological and commercial success.
The aircraft complete item first brief test flight in January 2019, where it took off, hovered and landed. As of December 2020, Boeing says the aircraft is "currently undergoing additional testing"
Boeing said in October 2019 how it plans, via its Aurora Flight Sciences division, to build an electric flying taxi with Porsche, the sports car maker owned by Volkswagen.
Airbus and Audi
As a sign of how invested major companies are in the concept of private flight, Audi and Airbus announced at the 2018 Geneva Motor Show that they are jointly working on a flying vehicle, called Pop.Up Next.
Unlike some of their rivals in this space, Audi and Airbus see a future where a two-person pod can either be flown autonomously by a detachable drone, or drive itself on the roads by attaching to an electric rolling chassis. Inside, passengers are entertained by a huge 49-inch touchscreen which wraps itself across the entire width of the cabin.
There are no details yet on speed, altitude or range, but the very fact companies like Audi and Airbus are making such prototypes says a lot about their position on these vehicles.
Audi said in October 2019 that it has put its flying taxi plans with Airbus on hold. The German carmaker described the shift in strategy as "a realignment of our urban air mobility activities" and said it hasn't yet made a decision on future products. Audi added how it will be "a very long time" before such flying machines are a reality.
One of the more surprising entries in this article, British sports car maker Aston Martin revealed a flying concept called the Volante Vision in July 2018. The company has partnered with Rolls-Royce (the engine maker) and the UK's Cranfield University to design the autonomous aircraft.
The Volante Vision offers space for three in its leather cabin, with one person sat in front of the other two and a jet fighter-style canopy above. Power comes from a gas turbine hybrid propulsion system developed by Rolls-Royce.
Aston Martin claims the vehicle could travel from London to Paris in about an hour - a journey which currently takes two hours and 15 minutes by train or an hour less by plane.
As of December 2020, the car maker hasn't said much more about its flying vehicle plans. Aston Martin has struggled financially in recent years, with its share price tumbling after listing on the stock market, stock of unsold cars building up, and a year-long delay to the James Bond movie No Time To Die, in which is vehicles feature heavily. Having been taken over and restructured by Canadian fashion mogul Lawrence Stroll, it seems unlikely that the Volante Vision will be in Aston Martin's pipeline anymore.
The German startup wants to offer autonomous airport transfersVolocopter
Taking a manned instead of autonomous approach (at least for now), the German-built Volocopter uses 18 quiet electric motors to carry a payload of up to 160 kg a maximum distance of 17 miles at 43 mph.
The two-seat aircraft, which resembles a helicopter with many more rotors, has a claimed top speed of 62 mph and is designed to fly no higher than 2,500 meters.
A white paper published by Volocopter in June 2019 claims the aircraft creates a sound of about 76 decibels when landing 100 feet away, only slightly more than the average of 73 decibels created by New York traffic.
Airport transfers could be big business for Volocopter, which points out that 70 percent of city centers have an airport within 12.5 miles, and 93 percent are no more than 18.5 miles from the nearest airport - a distance the electric aircraft should be able to manage. To that end, Volocopter has partnered with Frankfurt Airport to work on "developing concepts that allow for the connection of airports with urban transport infrastructure through air taxi services," the company says.
Investors who have pumped money into Volocopter include Daimler, parent of Mercedes-Benz, and Intel.
In November 2020 the company said its vehicle is the first commercially licensed electrically powered air taxi, and says public passenger flights (with a pilot at the controls) are scheduled for 2022 and will cost from $350 per ticket.
Larry Page-owned Kitty Hawk has a partnership with a New Zealand airlineKitty HawkKitty Hawk, the electric airplane startup backed by Google co-founder Larry Page, has a new aircraft. Called the Heaviside (shortened to HVSD), the plane is all-electric and Kitty Hawk's third such vehicle since the company was founded in 2015.
The HVSD has eight electric motors, each driving a propeller which can be pivoted up and down, allowing for vertical takeoff and landing. The aircraft requires no runway and can take off like a helicopter, before the propellers rotate and it flies forward like an airplane.
Kitty Hawk's big claim with the Heaviside is how quiet these electric motors are compared to conventional aircraft. The startup says the Heaviside emits 38 decibels of noise when hovering at 1,500 feet, compared to 80 dBA from a helicopter — which is approximately 100 times more, due to how decibels are calculated.
"Once in the air, the vehicle blends into the background noise of a city or suburb, barely discernible to the human ear," Kitty Hawk says.
Development and testing of the Heaviside continued through 2020, with over 237 successful transitions from hovering to forward flight during hundreds of test flights. The vehicle has also flown more than 100 mikes on a charge, using half the energy per mile of travel as a Tesla Model S, while going faster, at speed of up to 180 mph.
Built by a Canadian startup called Opener (and owned by Google co-founder Larry Page), the BlackFly's unique selling point is how it can be flown without a pilot's license — or so the company claims.
The strange looking machine can reportedly fly for 25 miles at speeds of up to 62 mph. It can carry one person, is fully electric with a charge time of 30 minutes, and has a fixed-wing VTOL design.
Opener claims to have already conducted over 1,000 test flights and flown more than 10,000 miles while developing the BlackFly. The flying machine has an automated return-to-home function that lets the pilot get back to their start point, and there will be an optional "ballistic parachute" for added peace-of-mind.
In January 2020, new Opener CEO Ben Diachun said the vehicle could be ready for delivery before the end of the year, having developed 28 test vehicles and flow 31,000 test miles. Opener said on Twitter in March 2020 it was improving its manufacturing processes and refining the design of its vehicle. It later announced the donation of N95 masks to help with the Covid-19 pandemic in April, but isn't tweeted since. The company's last press release was in July 2019.
