Americans will get an idea of what Cadillac's newest model will look like when President Bush rides down Pennsylvania Avenue on Thursday, the Associated Press (AP) said.

Bush will take part in the inaugural parade in a jet-black, Cadillac DTS limousine which will provide a glimpse of the design direction of the production version of the 2006 DTS, the report noted.

AP said GM will introduce the production version of the DTS at next month's Chicago Auto Show.

Similar to the production DTS, Bush's limousine highlights Cadillac's redesigned front and rear, while integrating the brand's signature egg-crate grille up front, the report said.

AP noted that the president's hand-crafted limousine is longer, wider and taller than the production model, and is equipped with state-of-the-art protection and communication systems. It seats six and the rear seat features a concealed, foldaway desktop.

Cadillac spokeswoman Kelly Wysocki told the news agency she could not discuss specifics of the arrangement between GM and the government, such as the cost of the vehicle or how many are produced.

The Associated Press noted that GM has produced limousines and other specialty vehicles for US presidents, ambassadors and foreign dignitaries since the early 1900s.
