Lahaye began his competitive career in karting between 1995 and 2001 before moving into open-wheel racing. He competed in Formula France and French Formula Renault as stepping stones, then in 2004 contested World Series Lights, finishing fifth in the standings and taking a round win at Valencia. In 2005 he moved to the Eurocup Megane Trophy with Tech 1 Racing, finishing ninth in his debut season before improving to runner-up in 2006 with three victories. He slipped to fifth place in 2007 with a single win before switching disciplines entirely.
From 2008, Lahaye committed to prototype endurance racing. His first season in the Le Mans Series came with Saulnier Racing, sharing a Pescarolo-Judd LMP2 car with Pierre Ragues and finishing fifth in the LMP2 category standings. That year also brought his first start at the 24 Hours of Le Mans, where he, Ragues, and China's Congfu Cheng finished 18th overall and third in the LMP2 class.
In 2009, the team was rebranded as OAK Racing. Lahaye partnered Karim Ajlani in the Le Mans Series LMP2 class, recording two podium finishes across the five-race season and finishing ninth overall. At Le Mans he was joined by Guillaume Moreau but the car retired. He also won both rounds of the 2009 Asian Le Mans Series held at Okayama, partnering team owner Jacques Nicolet and Richard Hein to take the class victories.
The 2010 season saw Lahaye partner Nicolet again in the Le Mans Series, finishing third in the LMP2 standings. At Le Mans he shared with Moreau and Jan Charouz, finishing seventh overall and second in the LMP2 class — his strongest result at the Circuit de la Sarthe.
The 2011 season brought serious setback. Competing in the LMP1 category of the Intercontinental Le Mans Cup with OAK, Lahaye suffered a heavy accident during qualifying at Spa-Francorchamps, sustaining two broken vertebrae, a broken hand, and an injured knee. The injuries forced him to miss the 24 Hours of Le Mans that year.
In 2012, Lahaye returned to full competition, joining the FIA World Endurance Championship in OAK's Morgan LMP2 car alongside Nicolet and Olivier Pla. His return to the top tier of endurance racing at that level demonstrated his recovery from the Spa accident and his continued relevance in the LMP2 class. He also made a further WEC appearance for the Ultimate team in 2022.
Lahaye's career combined a competitive ascent through French single-seaters with a decade-long commitment to prototype endurance racing at Le Mans Series and World Endurance Championship level. His co-ownership of Ultimate, competing alongside the Lahaye family logistics business, reflects his integration of motorsport and entrepreneurship — a combination that has kept him involved in top-level endurance racing well beyond his years as a front-running competitor.
