General Motors (GM -0.17%) launched its all-new Chevy Impala a couple of months ago, and sales have been pretty good. But sales totals don't tell the whole story. GM's new full-sized sedan comes with a strategy that's completely different from the outgoing car, one that's designed to maximize the numbers that are most important to GM's CEO: profits.

On that front, the new Impala is doing quite well. As Fool contributor John Rosevear explains in this video, the new Impala is just one of a series of all-new products that will seek to shift the General's position in the U.S. market in a big way -- a strategy that might already be beginning to bear fruit for GM shareholders.
