Musk puts a 2028 date on the thruster Roadster he first floated in 2017

A production date from Musk on this nameplate comes with a record. Customers could reserve a second-generation Roadster with a $50,000 deposit, or pay $250,000 upfront for a Founders Series model ^[10]. The 2028 date falls 11 years after the November 2017 unveiling ^[17]. With the wait creeping toward a decade, Musk apologized on an earnings call to "long-suffering" deposit holders and said Tesla was focusing heavily on its robotics and autonomy programs ^[12]. "Roadster is not just icing on the cake; it's the cherry on the icing on the cake," he said then ^[13]. Business Insider previously reported that Tesla began ramping up the Roadster's design cycle in the summer of 2025 ^[15].

The demo tested something narrower than a product. Musk said the car used "ultra high-pressure air tanks" to propel itself into the air ^[4]. During the event he said "it will probably work" ^[8], and on the livestream he said "Well, it worked" ^[7]. The 60 mph run Tesla showed, at 0.81 seconds, was a recorded demonstration ^[6].

The skeptics' case is about the stunt. Gene Munster, managing partner at Deepwater Asset Management, wrote on X that it "was an engineering flex with no commercial value beyond embarrassing traditional car makers" ^[19]. John Carmack, the former CTO of Meta's virtual reality division, wrote: "That demo involved a non trivial chance of embarrassing failure!" ^[18]. Both are verdicts on the demo. None of the reports includes a price for the production car, says whether it will carry the thrusters or describes certification work. Until one of those appears, the date rests on Musk's statement alone.

Legality is the one constraint Musk addressed directly. "I'm not sure it's necessarily legal in all jurisdictions," he said at the launch, and asked whether the car was street legal he answered, "Yeah, depends on your street" ^[16]. Production in 2028 could therefore mean a car that is sold or a car that flies, and we do not know yet whether those are the same car.

Business Insider offers a reason the date may matter less to Tesla than the demo did. It argued that the car makes Tesla look like a company that can build things others cannot, a message for Wall Street and for engineers Tesla wants to hire ^[20], and that the car "may not need to be a volume sales winner" to be a hit ^[21]. Musk has framed presentations this way before. Of a 2019 Neuralink presentation he said the "main reason for doing this presentation is recruiting" ^[22].

If that reading is right, the benefit arrives with the demo and the cost of missing 2028 arrives later, falling on customers waiting for a car. In our view the date starts to count when it comes attached to a price or a regulatory filing, and we would revise that view if either appears.
