William Lambros Bio
William J. Lambros (born May 6, 2003) is an American professional stock car racing driver. He last competed part-time in the NASCAR Craftsman Truck Series, driving the No. 2 Ford F-150 for Reaume Brothers Racing. A versatile competitor, Lambros has built his early career across karts, open-wheel cars, sports cars, and Modified Tour stock cars before stepping into NASCAR’s national ranks.
Early Life and Background
William J. Lambros was born on May 6, 2003, in Montauk, New York. Growing up in the small Long Island beach community at the eastern tip of New York State, he was introduced to motorsports at a young age. Lambros first raced at the age of five, competing in go-karts on local circuits, where his competitive instincts quickly emerged.
By the time he was thirteen, Lambros had won his first karting championship, marking him as a young talent to watch. After finishing high school, he pursued formal training to prepare for higher-profile competition. That preparation included completing both the Skip Barber 3-Day Racing School and the Skip Barber 2-Day Advanced Racing School, which gave him the credentials to race in larger and faster cars.
Path to NASCAR
Following his karting success, Lambros joined the Skip Barber Driver Development program in 2018, using it as a launchpad into car racing. He soon diversified his resume, gaining experience in series such as the SMART Modified Tour, the Monaco Modified Tri-Track Series, the Formula 4 United States Championship, the TC America Series, and the Michelin Pilot Challenge. Each step exposed him to different cars and track types, helping him develop a broad skill set.
Lambros’s progression through modifieds, open-wheel formula cars, and sports car racing gave him a versatile foundation. His performances in those series convinced him that the time was right to attempt NASCAR’s national ladder. The move was made official in 2025, when plans were announced for his debut in the NASCAR Craftsman Truck Series.
William Lambros Career
Early Career (2018–2024)
Lambros began his car racing journey in 2018 through the Skip Barber Driver Development program. He earned his racing license after completing both the 3-Day and 2-Day Skip Barber schools, a path that allowed him to gain experience in formula-style cars and sports cars. His early career included starts in the Formula 4 United States Championship, where he adapted to open-wheel racing at a young age.
Alongside his formula car work, Lambros sampled stock car racing through the SMART Modified Tour and the Monaco Modified Tri-Track Series in the northeastern United States. He also gained valuable seat time in the TC America Series and the Michelin Pilot Challenge. These varied experiences shaped him into a well-rounded driver, preparing him for the heavier, more powerful trucks of NASCAR competition.
NASCAR Craftsman Truck Series Debut (2025)
In 2025, it was revealed that Lambros would make his NASCAR Craftsman Truck Series debut at Lime Rock Park, driving the No. 2 Ford for Reaume Brothers Racing. The road-course debut marked a major milestone, giving the young driver his first start in one of NASCAR’s three national series. His selection highlighted the confidence that Reaume Brothers Racing placed in his road-racing background.
Lambros made his second Truck Series start later in the summer at Watkins Glen International, again behind the wheel of the same No. 2 Ford. Back-to-back road-course events allowed him to lean on his modified and sports car experience while adjusting to the pace and demands of NASCAR national series competition. These appearances established him as an emerging part-time competitor in the Truck Series garage.
Reaume Brothers Racing Era (2025)
Lambros joined Reaume Brothers Racing in 2025 as the driver of the No. 2 Ford F-150, campaigning a part-time NASCAR Craftsman Truck Series schedule. His Truck Series program began with the road-course debut at Lime Rock Park, where he turned his first competitive laps in series competition. The partnership with Reaume Brothers Racing provided a platform to showcase his skills on a national stage.
During his 2025 campaign, Lambros continued to log laps at another iconic road course, Watkins Glen International, expanding his experience at high-speed, technical venues. Competing for Reaume Brothers Racing gave him the opportunity to learn the routines of a NASCAR race weekend, including practice, qualifying, and pit work. His limited but focused schedule allowed him to gain national series exposure without overextending a still-developing team relationship.
Driving Style and Strengths
Lambros has built his reputation on road-course versatility, shaped by years in formula cars, modifieds, and sports car racing. His background in the Formula 4 United States Championship, the Michelin Pilot Challenge, and Modified Tour competition has given him comfort with technical circuits, heavy braking zones, and precise car control. Those strengths translate well to the road-course events that have defined his NASCAR Craftsman Truck Series starts to date.
Notable Races and Milestones
Lambros’s NASCAR Craftsman Truck Series debut at Lime Rock Park in 2025 stands as the headline milestone of his career so far. Adding a second start at Watkins Glen International later that same summer reinforced his commitment to road-course competition. Together, those two appearances marked his transition from regional and open-wheel racing to NASCAR’s national ranks.
