Ford Racing was founded in 1901 and is the high-performance division of Ford Motor Company that specializes in performance upgrades for their vehicle lineup. It was also the name used for all of its factory-backed motorsport activity. 

Today, the company has changed the name to Ford Performance but had kept that tradition of providing the highest quality of products.

Ford Racing has been actively participating in motorsport racing since the 1900s. They have used this to promote their brand and show the people what their vehicles can do when it comes to performance. 

Over the years of racing, they have produced many race winners and track records at the time, but their most memorable success was when they beat Ferrari at their own game during the Lemans 24 hrs race. The event was so successful, that they turned it into a blockbuster.
