Visualizing Drafting in NASCAR Racing

ESPN and SportVision have developed a live visualization of airflow around cars in a race.

"We continue to be fascinated with showing viewers things that you cannot see - the line of scrimmage in football, the strike zone in baseball, and the airflow in motorsports ... known as drafting," said Jed Drake, ESPN senior vice president and executive producer. "Draft Track brings to life for the viewer an element of NASCAR racing that has been a much-discussed but unseen part of the sport for decades."
