The EV600 electric van is scheduled to go on sale later this year through a new commercial business unit of GM's called BrightDrop.

The division is planning a full portfolio of electric products, not just vehicles, including a delivery pallet that was unveiled Tuesday. The potential foray into "personal air mobility" was announced as part of Cadillac's portfolio of luxury and EV vehicles. It included an autonomous shuttle and an electric vertical takeoff and landing (eVTOL) aircraft, or more commonly known as a flying car or air taxi.

Michael Simcoe, vice president of GM global design, said each concept reflected "the needs and wants of the passengers at a particular moment in time and GM's vision of the future of transportation. This is a special moment for GeneralMotors as we reimagine the future of personal transportation for the next five years and beyond." 

The flying vehicle is designed to hold one passenger and travel roughly 56 mph between rooftops and other urban destinations, according to the company.

A GM spokeswoman confirmed GM has designed models of both autonomous concepts, but computer renderings were simulated during the presentation. She declined to provide other details. Despite uncertainties around personal air mobility, Morgan Stanley expects the autonomous urban aircraft market may be worth $1.5 trillion by 2040.
