From 1984 to 2009,
Dale Earnhardt, Inc. (DEI) operated as a
NASCAR-related in
Mooresville, North Carolina, United States. The company was founded by
Dale Earnhardt and his wife,
Teresa Earnhardt. Earnhardt was a seven-time
Winston Cup champion. He
died in a crash on the closing lap of the
2001 Daytona 500. Despite his ownership of the DEI racing team, Earnhardt never drove for his team in the Winston Cup; instead, he raced for his long-time mentor and backer
Richard Childress at
RCR. In the late-2000s, DEI suffered critical financial difficulties when
Dale Earnhardt, Jr. left and
Anheuser-Busch and the
United States Army moved their sponsorships to
Gillett Evernham Motorsports and the newly-formed
Stewart-Haas Racing, respectively; DEI consequently merged with
Chip Ganassi Racing in 2009 to form
Earnhardt Ganassi Racing.
