Tesla may finally be preparing to unveil its long-delayed next-generation Roadster. According to people familiar with the plans, the company could hold a launch event as early as this month, potentially featuring a limited-edition model briefly lifting off the ground.

During the years-long development process, Tesla reportedly explored several concepts, including adapting the Model S Plaid platform and incorporating design elements inspired by the Lamborghini Countach and the SR-71 Blackbird reconnaissance aircraft.

The original Roadster was the vehicle that first put Tesla on the map. Over nearly a decade, CEO Elon Musk repeatedly expanded his ambitions for its successor—from building the world’s fastest production car to creating something more extraordinary than all the fictional vehicles in the James Bond films combined. He has also claimed that the car would be able to fly.

Those shifting goals reportedly sent Tesla’s designers through years of repeated revisions. The company unveiled a prototype of the second-generation Roadster and began accepting reservations in 2017, but later substantially reworked the original concept. The redesigned version has yet to be shown publicly, while production and delivery plans have been repeatedly delayed.

Three people familiar with the matter said Tesla is preparing an unveiling event at SpaceX’s testing facility in McGregor, Texas. The event could include a carefully staged demonstration of a limited-edition Roadster jointly developed by Tesla and SpaceX.

The vehicle is expected to use cold-gas thrusters to achieve a brief hovering or “flying” effect. Musk has previously said the thruster system was being developed with SpaceX.

Several months ago, Tesla reportedly considered an even more ambitious stunt resembling a scene from a science-fiction film. The plan involved sending the Roadster onto a magnetized, roller-coaster-style ramp, briefly driving it upside down, rotating it upright and then hovering in midair.

The final demonstration remains subject to change. One person familiar with the project said the initial plan was postponed after a rehearsal for Musk, and parts of the presentation have since been scaled back.

Musk has reportedly acknowledged to some Tesla employees in recent weeks that the demonstration will be extremely difficult to execute and could go wrong, but that it should be highly entertaining regardless of the outcome.

Tesla has not officially confirmed the event’s date or the details of the planned demonstration.
