General Motors expects to redesign, refresh or replace nearly 90% of its vehicles in the North American market from 2013 to 2016, according to a presentation to be made today at a conference in New York.

The automaker will double its pace of product improvements during that three-year period, compared to 2009 to 2012, GM North America Chief Financial Officer Chuck Stevens plans to tell analysts this morning.

In 2013, GM expects to refresh 39% of its North American product portfolio, fueled by redesigned vehicles such as the Corvette Stingray, Chevrolet Impala and Cadillac CTS.
