DETROIT -- This was perhaps the most triumphant day for the United States auto industry's Big Three companies in more than three years. 

With glitz and glamour, the executives of Ford, General Motors and Chrysler all introduced new models from some of their brands Monday at the 2012 North American International Auto Show in Detroit. 

Some that made noise leading up to the show -- and certainly after they were unveiled -- were the Dodge Dart, Ford Fusion, Chevrolet Sonic, and a couple of Chevy concept cars, the Code 130R and Tru 140S. 

Let's compare the measurables of the Big Three's offerings:

Ford Fusion: Features both gas-powered, hybrid and plug-in hybrid versions; 40 mpg highway in gas-powered version; price was not specified, but will be comparable to the current Fusion, which starts at $20,200. Will compete in midsize market.

Dodge Dart: Expected to be able to acheive 40 mpg highway, but Dodge CEO Reid Brigman would not specify whether that was only in economy versions of the car; starts at $15,995. Will compete in compact market.

Chevy Sonic: 35 mpg highway. Expected to start at $14,995. Will compete in subcompact market.

And now, compare their designs for yourself by looking at the pictures ahead.
