DETROIT, Michigan - The world's automakers are betting big on the 2013 North American International Auto Show with nearly 50 products to be launched.The show will open to the public on January 19 at Detroit's downtown Cobo Centre, the Detroit News reported, adding that most of the "reveals" would be global.More than 30 brands will be featured and several will be returning to the show, among them Jaguar, Land Rover, Ferrari and Maserati.CADILLAC MOVES HOUSEThe Chinese will be there, represented by Guangzhou Automobile with a new car and to make it all worthwhile about 5500 motoring journalists from more than 60 countries have registered to attend the news media days - January 14/15.The show's organisers, the DetNews adds, are promising some significant changes over 2011, among them a three-story atrium for high-profile show events.General Motors is separating Cadillac from the rest of its brands, the display near Ferrari, Volvo and Porsche.GM spokesman David Caldwell to the newspaper: "It's mainly just an effort to place Cadillac within the context of our luxury competitors. That's better for people attending the show, too, making it easier to compare and shop for cars in the same segment or category."TOYOTA IN NEW SPACEFord is planning major changes to its stand, which this time will feature historical re-enactments and vintage vehicles highlighting the automaker's illustrious past.Toyota will be the first automaker to try out the 2800 square metres of floor space added before the 2011 show.There had been concern that the proliferation of "social media" would undermine the importance of auto shows but organisers believe Twitter and similar media are driving more people to the Cobo Centre."We were worried about that," a spokesman told the Det News, "but right now our show is going up in popularity and demand for floor space is at a premium."People still want to touch, and feel and smell cars."
