A new video Tesla posted to YouTube shows an image of an unnamed vehicle partially hidden by a sheet, and footage of passengers reacting to the acceleration of Tesla's planned second-generation Roadster.

The video, posted Wednesday, first pointed out by electric vehicle blog Electrek, is a stab at generating hype around Tesla's brand days after CEO Elon Musk behaved antagonistically toward Wall Street analysts during the company's first-quarter earnings conference call.

Some of the viewers on the video and in other venues are speculating the vehicle under the sheet is the planned Model Y, a crossover based on the Tesla Model 3 sedan, a $35,000 mass-market vehicle which is in high demand, but which Tesla has struggled to produce.

Tesla was not immediately available for comment.
