Lilium has begun assembly of the propulsion system for its electric vertical take-off and landing Lilium Jet

Lilium is developing an electric vertical take-off and landing (eVTOL) "jet," which uses ducted electric vectored thrust engines. It's not a jet engine in the traditional sense, but an electric motor-driven propulsion system. The distinction lies in the absence of combustion; it relies on electric motors to power fans for thrust. So, while it's called a "jet," the term is being used more for marketing than technical accuracy.
