Tesla has announced that the long-awaited second-generation Roadster will finally be unveiled on October 1, a mere eight years after Elon Musk first promised it. In a post on X on Saturday, the company offered the kind of detail-rich communication it's famous for: "Go for launch," accompanied by a graphic reading "10.01." So mark your calendars, assuming you haven't already marked them several times before.

The graphic also appears to tease the cold gas thrusters that Musk has promised will let the Roadster fly - or at least hover menacingly - developed by SpaceX, his other big company. Because nothing says "practical sports car" like strapping rocket technology to it and hoping for the best.

The second-gen Roadster was first announced in November 2017 and has been delayed so many times that it's become less a vehicle and more a recurring calendar event. It even sparked a social media spat between Musk and OpenAI CEO Sam Altman last year, when Altman noted that "7.5 years has felt like a long time to wait" after putting down a $50,000 reservation fee. Musk countered that Altman had received a refund, which is one way to resolve a customer service complaint.

The Information recently reported that the 2017 version of the car was completely abandoned in favor of a new, yet-to-be-revealed design that would be shown imminently. Imminently, in Tesla time, is a flexible concept.

And just to manage expectations: Musk has previously acknowledged that even after the big reveal, the Roadster won't actually go into production for another 12 or 18 months. So if you're keeping score at home, that's a reveal on October 1, followed by a production timeline that could generously be described as "eventually."
