Peter DempseyPeter Dempsey is an Irish race car driver, engineer and driver development leader with a lifetime of motorsport experience. Peter began his career racing go-karts in Ireland at age 8. In 2004, he began racing competitively in the Formula Ford Series in Ireland and the UK as a driver for his father's racing team, Cliff Dempsey Racing. In 2005, he entered into his first full season of competitive racing in the Formula Ford Series where he won 33 out of the 43 races that he competed in. That same year, Peter was awarded the Motorsport Ireland Young Racing Driver of the Year Award. From 2006-2007, Peter continued to win numerous races and awards including third overall in the Formula Ford championship in 2006, two more nominations for the Motorsport Ireland Young Racing Driver of the Year Award, and the prestigious Walter Hayes Trophy both years in a row. In 2008, Peter boldly decided to move his racing career to the U.S.A. where he saw a major opportunity in the open-wheel development ladder. He completed his first season in the Star Mazda Championship with four wins, seven podiums, and third overall in the driver's championship. He entered the series once again in 2009 winning five races, six podiums, and finishing second in the driver's championship after a devastating DNF in the final event. In 2010, Peter broadened his racing resume further by racing an LMP2 car in the world famous 10-hour Petit Le Mans event at the Road Atlanta road course. He also made a trip back home to compete in both the Formula Ford Festival and the Walter Hayes Trophy which he won for the third time, becoming only the second driver to ever do so. From 2011-2013, Peter competed in the Firestone Indy Lights Series where he accomplished eight podium finishes and a record-breaking win that ended in a four-wide finish with a .0026-second margin of victory, going down in history as one of the most exciting finishes in the history of the Indianapolis Motor Speedway. In addition to his own racing resume, Peter has enjoyed mentoring and coaching many drivers to reach their full potential as they climb the motorsports ladder. It was this gratification along with his extensive racing experience that led Peter to form Turn 3 Motorsport.
