Inside Track: Refueling the Business of NASCAR, hosted by Emmy-Nominated CNBC Sports Business Reporter Darren Rovell, examines a sport that was once seemingly unstoppable. Infamous for its ties to southern bootleggers and famous for filling some of the largest venues in the world - 200,000 fans at some speedways – a decade of growth made it the fastest growing sport in America.

But the rise of the 90s has given way to a new century recession. An imploding car business and shrinking sponsorship budgets are threatening the corporate dollars that are the sport's very lifeblood. Owned and controlled by the France family, NASCAR is looking at ways to weather the storm.

Darren Rovell takes you inside the garage of driver turned owner Tony Stewart and a never before seen look at how NASCAR sponsors are looking for business – from each other. Inside Track takes the viewer under the hood for a look at the people behind the iconic American companies that have stuck with this sport that was born more than five decades ago.
