Hyundai and KAI Partner to Develop Electric Advanced Air Mobility Aircraft

Updated on May 25, 2026 • 3 min read

Hyundai Motor Group and Korea Aerospace Industries have signed a memorandum of understanding to jointly develop advanced air mobility aircraft based on electrified aviation powertrains.

The agreement brings together Hyundai’s electric mobility and manufacturing capabilities with KAI’s aircraft development, airframe engineering and aerospace certification experience.

Supernal and KAI to jointly develop AAM aircraft

Under the agreement, Hyundai’s U.S.-based AAM affiliate Supernal will work with KAI on aircraft development.

The partnership will focus on:

• electric aviation powertrains
• AAM aircraft airframe development
• mass production strategy
• certification cooperation
• supply chain development
• global customer networks

Hyundai Motor Group and KAI will also separately collaborate on commercialization of electrified aviation powertrains developed by Hyundai’s Aviation Powertrain Sub-Division.

Why the partnership matters

AAM aircraft require a combination of automotive-scale production and aerospace-grade safety.

Hyundai brings:

• electrification expertise
• battery and powertrain knowledge
• large-scale manufacturing capability
• mobility ecosystem experience

KAI brings:

• fixed-wing aircraft experience
• rotorcraft systems expertise
• airframe development capability
• aerospace certification knowledge
• composite structure experience

This combination is important because future AAM programs must move beyond prototypes into certified, repeatable production.

Composite airframes will be central

Although the announcement focuses on electrified powertrains, advanced composite structures are likely to play a key role in the aircraft platform.

AAM aircraft need:

• lightweight airframes
• high fatigue resistance
• efficient aerodynamic structures
• scalable production methods
• crashworthy cabin designs

KAI has previous experience with eVTOL airframes, thermoplastic composites and infused composite structures, making it a valuable partner for future lightweight aircraft development.

Commercialization challenges remain

The partnership will still need to solve major AAM industry challenges, including:

• battery energy density
• aircraft certification
• noise control
• infrastructure readiness
• high-rate manufacturing
• operating cost reduction
• regulatory acceptance

The agreement’s supply chain and certification cooperation language is especially important because those areas often determine whether AAM concepts become commercial aircraft.

Editorial Perspective

This MOU matters because AAM is shifting from concept design to industrial execution.

Many companies can build demonstrators. Far fewer can certify, manufacture and support aircraft at scale.

Hyundai and KAI are trying to combine two different strengths: automotive industrialization and aerospace discipline. If successful, the collaboration could position South Korea as a serious competitor in the global electric air mobility market.
