Hendrick Motorsports and NASCAR's most popular driver, Dale Earnhardt Jr., receive millions of dollars through the Pentagon's racing sponsorships.
With earnings in the $29 million range in 2010, Earnhardt remains NASCAR's highest-paid driver, Forbes reports.
Earnhardt and two of his teammates at Rick Hendrick's championship-winning organization finished the year 1-2-3 in earnings, the same showing ranking as in 2009, according to the Forbes analysis of NASCAR that is done annually.
Jeff Gordon earned about $25 million and five-time Cup champion Jimmie Johnson $24 million.
The figures include race earnings, sponsorship payments and merchandising royalties.
The earnings of all three were down marginally in 2010 from the previous year, according to the Forbes examination.
The Hendrick organization also stayed atop the heap in overall valuation, Forbes said.
Forbes placed the Hendrick organization's value at $350 million and reported it had revenues of $177 million in 2010. Roush Fenway Racing was a distant second in that category, Forbes said, valued at $224 million with 2010 revenues of $140 million.
