No, Batman hasn't taken up fighting crime in Detroit, that's just General Motors and Chevrolet pulling out all the stops for the announcement of the Chevy Lego Batmobile. The symbol switches back and forth from Batman to the Chevy bow-tie:

In a Saturday morning, Jan. 14 surprise reveal, Chevrolet showed off a man-made Batmobile which will be used in the upcoming "The Lego Batman Movie." The Chevy Lego Batmobile was created through a three-way partnership between Chevy, Warner Bros. and Lego.

The Chevy Batmobile is 17-feet-long, weighs just less than 1,700 pounds and used nearly 350,000 individual Lego pieces.

The vehicle shown in Detroit was inspired by Batman's Speedwagon used in the movie that will hit theaters in the U.S. Feb. 10.

Erik Varszegi, lead designer, and Jeff Rushby, lead builder, said that the design process took about 220 hours of work and the actual production took another 1,800 hours. The two led a team of 68 people.
