Despite big success in places like China, General Motors (GM 4.37%) has had a rough time in the U.S. market recently. Products that had fallen behind competitors', plus lingering resentments over GM's 2009 bailout, left GM's market share last year at lows not seen in decades.

That may be starting to turn around, as GM's latest products have impressed critics and buyers alike. Analysts are saying that GM's sales growth in July might outpace Ford's(F 0.47%) – or put another way, GM looks to be gaining back some of that lost market share. In this video, Fool.com contributor John Rosevear looks at the latest forecasts – and at some of the key factors driving the U.S. auto market right now.
