Electric car designs for secretive automotive startup Faraday Future of Gardena were published today on the company’s app, according to website Engadget.

The company was set to unveil its electric car concept tonight at the Consumer Electronics Show in Las Vegas, but some early drawings of the concept car were inadvertently posted on Faraday’s promotional app, according to the report. The images have since been taken down.

Those images showed a Batmobile-like electric car that claims performance of 1,000 horsepower, the ability to go from zero to 60 miles per hour in less than three seconds and a top speed of over 200 miles per hour.

Founded in 2014, Faraday reportedly has more than 400 employees, a plan for a $1 billion plus manufacturing facility in Nevada and the backing of a Chinese billionaire.
