Introduction: What is eVTOL and Why Does It Matter

eVTOL (electric Vertical Take-Off and Landing) refers to aircraft capable of vertical takeoff and landing using electric power. While they may resemble helicopters, the use of electric motors creates fundamental differences: significantly lower noise levels, reduced operating costs, and zero carbon emissions.

eVTOL aircraft are receiving enormous attention as the core vehicle for Urban Air Mobility (UAM), with the potential to dramatically reduce short-distance travel times within cities. For example, the journey from Manhattan to JFK Airport, which takes over an hour by car, could be completed in approximately 7 minutes by eVTOL.

UAM Market Size Projections

Leading financial institutions and consulting firms project the UAM market as follows:

• Morgan Stanley: Forecasts the global UAM market to reach approximately $1.5 trillion by 2040
• McKinsey: Predicts the Advanced Air Mobility (AAM) market will reach $30 billion annually by 2030
• Deloitte: Projects the US AAM market alone will grow to $115 billion by 2035
• Roland Berger: Estimates annual UAM passengers will reach billions globally by 2050

Dozens of eVTOL companies are competing to capture this massive market opportunity, with Joby Aviation, Archer Aviation, and Vertical Aerospace standing out as the most prominent publicly traded companies.

Revenue Generation Timeline

All three companies have yet to generate meaningful revenue. Even after commercial operations begin, reaching profitability is expected to take considerable time.

• Joby: Initial commercial revenue expected in 2026-2027
• Archer: Initial revenue expected in 2026-2027, focused on United Airlines routes
• Vertical: Revenue generation expected from 2027-2028 onward

TAM (Total Addressable Market) Claims

TAM figures presented in each company's investor presentations tend to be highly optimistic:

• Joby: Opportunity worth tens of billions annually in the global short-distance transportation market
• Archer: US urban air taxi market alone worth tens of billions
• Vertical: Hundreds of billions in the European and global regional aviation market

Investors should evaluate realistic penetration rates and achievable market size conservatively rather than accepting these TAM figures at face value.

Competitive Landscape: Other Key Players

Lilium - Lessons from Bankruptcy

German eVTOL company Lilium was once considered one of the industry's most promising players but filed for bankruptcy in late 2024 due to funding shortfalls. Lilium's case provides several important lessons:

• eVTOL development requires far more capital than initially anticipated
• Funds raised through SPAC listings alone may be insufficient to reach certification
• Proprietary technology (ducted fan approach) does not necessarily guarantee market advantage
• Risk of failing to secure government subsidies/emergency funding

Note: A European investor consortium subsequently showed interest in acquiring Lilium's assets, leaving open the possibility of partial company restructuring.

EHang (China)

• China's leading eVTOL company, first in the world to obtain type certification for an autonomous eVTOL (EH216-S)
• Certification from the Civil Aviation Administration of China (CAAC) obtained in 2023
• Differentiated from Western competitors through unmanned autonomous flight approach
• Already conducting pilot operations for tourism, short-distance transportation, and logistics
• Advantaged by the large Chinese domestic market, but global expansion constrained by US-China tech competition

Wisk Aero (Boeing-Backed)

• Wholly owned subsidiary of Boeing, developing autonomous air taxis
• Differentiated by its long-term vision of fully autonomous, pilotless flight
• Backed by Boeing's aviation certification experience and financial resources
• Commercial operations may come later than other companies, but operational costs could be dramatically reduced once autonomous flight is achieved

Other Notable Companies

• Beta Technologies: Developing cargo/logistics eVTOL, UPS partnership
• Volocopter: German company, multicopter approach, had planned Paris Olympics demonstration flights but experienced delays
• SkyDrive: Japanese company, targeting Osaka Expo 2025 demonstration flights

Key Risk Factors

1. Certification Delay Risk

FAA/EASA eVTOL certification is an unprecedented process. It may take longer than expected, and additional requirements may emerge. Historically, certification of new aircraft categories has almost always been delayed.

2. Battery Technology Limitations

Current lithium-ion battery energy density (approximately 250-300 Wh/kg) imposes constraints on eVTOL range and payload capacity. The commercialization timeline of next-generation battery technologies (solid-state batteries, lithium-sulfur, etc.) is directly linked to eVTOL performance improvements.

3. Public Acceptance

Public perception of safety and acceptance of flying taxis remains unproven. Community concerns about noise, safety, and privacy could become obstacles to service expansion.

4. Regulatory Environment

• Urban airspace flight path approvals
• Noise regulations
• Privacy issues (aerial photography along flight paths, etc.)
• Complexity of global expansion due to varying regulations across countries

5. Intensifying Competition and Funding Shortages

The eVTOL industry faces fierce competition at a stage where revenue has yet to materialize. Enormous capital is required to reach certification and commercialization, and more companies may follow Lilium's path to bankruptcy.

FAQ

What is the biggest difference between eVTOL and helicopters?

The most significant difference is the power source. Helicopters use fossil fuel-powered turbine engines, while eVTOLs use electric motors and batteries. This results in dramatically lower noise (approximately 1/100th of helicopter levels), lower operating costs, simpler maintenance, and zero carbon emissions. Additionally, distributed electric propulsion (DEP) improves safety - if one motor fails, the aircraft can continue flying safely on the remaining motors.

Which company is the most promising among Joby, Archer, and Vertical?

Each company has distinct strengths and weaknesses, making a definitive ranking difficult. Joby benefits from the longest track record, extensive test flight experience, and Toyota's manufacturing support. Archer's strengths lie in its strong partnership with United Airlines and Stellantis's mass production capabilities. Vertical Aerospace's advantages include partnerships with aviation industry giants like Rolls-Royce and Honeywell, along with its European market positioning strategy. From an investment perspective, certification progress, cash position, and the substantive value of partnerships should all be evaluated holistically.

What is the expected price of an eVTOL air taxi ride?

Premium pricing is expected during the initial phase. The industry targets long-term pricing of $3-$5 per mile, comparable to or slightly higher than UberX. Initial pricing is expected to start at approximately $6-$9 per mile, gradually decreasing as economies of scale and technological advances take effect.

Are eVTOLs safe?

eVTOL companies claim high safety levels through distributed electric propulsion (DEP) technology. Using multiple independent motors means the aircraft can continue flying and landing safely even if one fails. Additionally, passing rigorous FAA/EASA certification ensures that commercial operations will guarantee safety levels equivalent to existing aircraft. However, large-scale commercial operational experience is still lacking, so empirical safety data will take time to accumulate.

Is UAM service possible in Korea?

The Korean government is fostering UAM as a national strategic industry. The Ministry of Land, Infrastructure and Transport is conducting the K-UAM Grand Challenge, with a roadmap established targeting commercialization from 2025. Korean companies including Hanwha Systems, Hyundai Motor Company (Supernal), and Korean Air are actively participating. Routes between Seoul-Incheon Airport and within central Seoul are being evaluated as initial operating corridors.
