The Airspeeder Mk4 is described as the first crewed version of this spaceship-style vehicle that's designed to hold ultra-fast races. Adelaide company Alauda Aeronautics previously claimed the Mk4 as the world's fastest electric Vertical Take-Off and Landing (eVTOL) aircraft. It flies off the success of the remotely-piloted Mk3, which had successfully completed more than 350 test flights and taken part in two Airspeeder demonstration races in South Australia. The Mk4 utilises a hydrogen-electric powertrain and features eight ducted propellers with 360-degree dual gimballed capability, allowing for exceptional maneuverability.
