Teresa Earnhardt remains mysterious figure

Were he alive today, Dale Earnhardt likely wouldn't recognize the NASCAR team that bears his name.

His son, Dale Earnhardt Jr., is gone, driving for a rival organization. What used to be known as Dale Earnhardt Inc. (DEI) is now called Earnhardt Ganassi Racing, the result of an economics-driven merger.

At the helm, as she has been since the NASCAR legend's death in the 2001 Daytona 500, is his widow, Teresa Earnhardt. She now shares control of the team with Chip Ganassi and Felix Sabates, but she remains the face of the franchise.
