Reviving an old thread. Hyundai says it will be ready by 2028.
Story here. The article answers some of the questions that were asked in this thread before.
"The company says its aircraft will operate as quietly as a dishwasher, emitting 65 decibels in vertical takeoff and landing phases and 45dB while cruising horizontally."
"Supernal, the automaker’s eVTOL division, says its S-A2 concept can cruise at 120mph and reach an altitude of 1,500 feet. It packs enough battery capacity for the type of 25- to 40-mile trips that helicopters commonly conduct between downtowns and airports for wealthy business types."
