The Future of Advanced Air Mobility and the Reality

 

 

Advanced Air Mobility (AAM) promises a sci-fi future where electric vertical takeoff and landing (eVTOL) aircraft zip passengers over traffic-clogged cities, slashing commute times while cutting emissions.

Companies like Joby Aviation, Archer Aviation, and Lilium have fueled imaginations with sleek designs and bold projections, drawing billions in venture capital (VC).

Yet, the gap between glossy renders and operational reality raises questions about feasibility, especially in the near term.

But are the eVTOLs a transformative leap or just another overhyped dream burning through investor cash?

The Allure of eVTOLs and VC Frenzy

eVTOLs, often dubbed “air taxis,” combine helicopter-like vertical takeoff with airplane-like cruising, powered by electric batteries.

The pitch is compelling: quieter, greener, and faster than ground transport, they could revolutionize urban mobility. McKinsey estimates the AAM market could reach $1 trillion by 2040, with 45,000 eVTOLs in service globally.

This potential has lured VCs and corporate giants alike. Joby Aviation has raised over $2 billion, including from Toyota and Delta Air Lines, while Archer secured $850 million in 2025, boosting its liquidity to $2 billion. Lilium, before its insolvency filing in 2024, attracted $1 billion from investors like Tencent.

Investors see a “category killer” opportunity, betting on first-mover advantages in a market that could rival regional airlines. Yet, history shows that capital-intensive hardware ventures often falter.

The 2024 collapse of Lilium, despite its hefty funding, underscores the risks. High-profile failures, like the fizzled Paris Olympics air taxi plan, highlight how promises often outpace delivery. VCs are drawn to the hype, but the path to profitability is littered with technical and regulatory hurdles.

Technical and Economic Challenges

eVTOLs face formidable obstacles. Battery energy density, currently around 200 Wh/kg, needs to nearly double to meet the range (70-80 miles) and payload (3-4 passengers) requirements for viable air taxis.

Current lithium-ion batteries struggle with aviation’s safety and weight demands, and breakthroughs remain speculative. Noise, while lower than helicopters, is a concern in urban areas, requiring costly mitigation.

Infrastructure like vertiports, charging stations, and air traffic management demands billions in investment. Scaling these to support a dense network is a decades-long endeavor. Economically, eVTOLs are a tough sell.

A 2025 study pegs operating costs at $0.61/passenger-km, competitive only with autonomy and better batteries. Without these, air taxis remain a premium service for high-income travelers, not a mass-market solution.

Ground transport, especially autonomous taxis, is often cheaper. Initial losses are expected, as seen with Uber and Lyft, but eVTOL operators face higher capital costs and stricter safety standards.

Joby and Archer, both pre-revenues, are burning cash. Joby with $1.3 billion in liquidity and Archer with $2 billion yet face dilution risks if certification delays hit.

Regulatory and Safety Barriers

The FAA’s Innovate28 plan aims for eVTOL operations by 2028, but certification is a bottleneck. The process for powered-lift aircraft is uncharted, with safety standards far stricter than for drones.

Joby and Archer have logged test flights, but full commercial approval remains uncertain. The FAA’s October 2024 rule on powered-lift operations sets pilot and operational standards, but evolving air traffic management for congested urban skies is complex.

Public acceptance is another hurdle. A 2024 survey of 975 U.S. respondents showed interest in eVTOLs but hesitancy to fly early, with willingness dropping in poor weather. Building trust requires time and flawless safety records.

Case Studies: Hits and Misses

Joby Aviation: Joby is a frontrunner, with $1.3 billion in cash and over 1,000 test flights by 2025. Its S4 aircraft targets 100-mile ranges and four passengers. Partnerships with Delta and Uber bolster its mobility platform, but Joby’s $400 million annual cash burn raises concerns. It aims for commercial operations by 2026, assuming no regulatory snags.

Archer Aviation: Archer’s Midnight aircraft, designed for short urban hops like Manhattan to JFK, has United Airlines as a partner. Its $850 million raise in 2025 reflects investor confidence, but dilution hit its stock hard. Certification progress lags Joby’s, and cash burn remains high.

Lilium: The German startup’s insolvency in 2024 is a cautionary tale. Despite at least $1.5 billion in funding, Lilium struggled with battery limitations and high development costs. Its jet-based eVTOL design was innovative but unviable without major capital.

Feasibility in the Near Future

In the next 5–10 years, AAM is feasible but limited. Small-scale operations, think of something like elite shuttle services or cargo delivery, are likely by 2028, as per the FAA’s timeline.

Joby and Archer may launch in select cities, but mass-market air taxis are a 2035+ prospect. Battery advancements, vertiport networks, and autonomous systems are critical, and none are guaranteed soon.

IDTechEx forecasts a $20 billion market by 2044, but this assumes steady progress. Public adoption, cost reduction, and regulatory clarity will dictate scale. For now, eVTOLs risk being a niche luxury, not a commuter staple.

Conclusion

AAM and eVTOLs hold transformative potential, but the road is treacherous. VCs are betting big, lured by trillion-dollar projections, but technical, economic, and regulatory barriers temper optimism.

Case studies like Lilium’s failure and Joby’s progress show both the promise and peril. Near-term feasibility hinges on incremental wins, that is, limited routes, cargo use, and regulatory milestones. Until batteries improve and infrastructure scales, air taxis remain a high-risk, high-reward gamble for investors.
