More than five years after the worst financial crisis since the Great Depression shook global economies and markets alike, some top CEOs told CNBC on Monday the U.S. economy has finally begun to rev up, with a strong growth outlook across the board, but especially in the automotive sector.

The head honchos—representing major retailers and automakers—acknowledged the recent growth may have gone unnoticed, especially as job creation in December was at its lowest level in nearly three years. The economy produced just 74,000 jobs in December, far fewer than the roughly 200,000 jobs economists had forecast.
