Makowiecki began his motorsport journey in karting before progressing to single-seater competition in the French Formula Three Championship, where he finished fourth in Class B. His career trajectory soon turned decisively toward GT and endurance racing, disciplines in which he would make his name over the following two decades.
From 2003, Makowiecki became a fixture in the Porsche Carrera Cup France. He placed third in the points standings in 2004 and again in 2009, and finished second in both 2006 and 2007. His persistence was rewarded in 2010 when he took the championship title outright, delivering six victories, eleven podiums, and three pole positions across the season.
Makowiecki first entered the FIA GT3 European Championship in 2009, driving for Hexis Racing AMR and finishing fourth in the championship. He continued with Hexis into the 2010 FIA GT1 World Championship, then moved to Marc VDS Racing Team for 2011 before returning to Hexis for 2012.
His World Endurance Championship debut came in 2011 with Luxury Racing, continuing with that team into the opening phase of the 2012 FIA World Endurance Championship season. At the 24 Hours of Le Mans that year, his final race with the team, he claimed pole position — a landmark result that announced him as a serious force in prototype and GT competition.
He joined Aston Martin Racing for 2013 and delivered two race victories: the 6 Hours of Circuit of the Americas and the 6 Hours of Fuji. In Japan that same year, driving alongside Naoki Yamamoto for Weider Dome Racing in Super GT, he won the 42nd International Pokka Sapporo 1000km at Suzuka Circuit.
Makowiecki became a Porsche Motorsport factory driver in 2014, debuting in the GTE-Pro class with Porsche AG Team Manthey in that year's FIA World Endurance Championship. The factory relationship proved enormously successful across the following decade.
His most significant victories in Porsche colours include:
2018 and 2019 12 Hours of Sebring
2018 and 2020 Petit Le Mans
2022 24 Hours of Le Mans
All of these wins came in Porsche 911 machinery, cementing his reputation as one of the most dependable pilots in Porsche's GT stable.
For the 2023 FIA World Endurance Championship season, Makowiecki moved into the top Hypercar class, driving the Porsche 963 alongside Dane Cameron and Michael Christensen. His transition to the premier prototype category represented the logical next step after a decade of sustained GT excellence.
He subsequently made a further transition by joining the Alpine Endurance Team in the Hypercar category, where he continues to compete.
Makowiecki's career illustrates the sustained value of marque loyalty and technical expertise within factory GT programmes. His five major endurance victories across Sebring, Road Atlanta, and Le Mans — all achieved within the Porsche factory structure — place him among the most decorated Porsche factory drivers of the 2010s and early 2020s. The 2022 Le Mans victory in particular stands as the crowning achievement of a career built steadily on class and consistency.
