The big data behind Indy Car racing

Team owner Roger Penske, president of Penske Racing, Tim Cimdric, Helio Castroneves, driver of the #3 Team Penske Dallara Honda, engineer Ron Ruzewski, crew chief Rick Rinaman, celebrate in victory lane after winning the IRL IndyCar Series 93rd running of the Indianapolis 500 on May 24, 2009

The biggest film hitting theaters this weekend is Ron Howard's "Rush," a story about Formula One race car drivers in the 1970s. These days if Formula One drivers want to win big, the way to win is with the help of tiny sensors and big data. As important as a race car driver's skills is the ability of their team to crunch numbers with the help of all kinds of computing. One guy prepping for next weekend's big Indy Car Grand Prix in Houston is Ron Ruzewski. He's the technical director for Penske's Indy Car racing division. Ruzewski says using sensors to collect and analyze data helps Penske work with its drivers.
