Lucas Fenhaus (born April 8, 2004) is an American professional stock car racing driver. He competes part-time in the NASCAR O'Reilly Auto Parts Series, driving the No. 5 Ford Mustang Dark Horse for Hettinger Racing. He has previously competed in the NASCAR Craftsman Truck Series, the ARCA Menards Series, ARCA Menards Series East, and the Superstar Racing Experience, and from 2019 to 2021 was a part of the Kulwicki Driver Development program.

Racing career Early career

Fenhaus was inspired to race after watching his cousin, father, and grandfather race snowmobiles on ice oval tracks. He would start racing snowmobiles and then began racing on pavement in go-kart and bandolero racing. At the age of fourteen, he began competing in late model racing events at State Park Speedway in his hometown of Wausau, Wisconsin. Growing up, he watched races at the track and was inspired by Tim Sauter and his success in races there. He was part of the Alan Kulwicki driver development program and would win the Lodi Memorial and the 2018 track championship at State Park Speedway.

After winning the 2021 Slinger Nationals, Fenhaus earned a spot in the Superstar Racing Experience race at Slinger Speedway. He competed in the race against many current and former NASCAR and IndyCar drivers and finished second (behind Marco Andretti) and led the most laps.

CARS Tour In the CARS Tour, Fenhaus drove the No. 96 Chevrolet for Highlands Motorsports in 2022 and won the championship in their Pro Late Model Tour.

ARCA Menards Series In January 2022, Fenhaus drove a stock car for the first time as he tested an ARCA Menards Series car in the series' preseason test session at Daytona International Speedway for Fast Track Racing. He did not end up running any ARCA races for Fast Track or another team in 2022.

On March 3, 2023, it was announced that Fenhaus would run the full season in the ARCA Menards Series East for the new Pinnacle Racing Group team in their No. 28 car. After winning two races at Nashville Fairgrounds Speedway and Iowa Speedway, he finished second in the championship to William Sawalich after suffering a crash in the season finale at Bristol Motor Speedway.

NASCAR Craftsman Truck Series

In 2024, it was revealed that Fenhaus would make his debut in the NASCAR Craftsman Truck Series at World Wide Technology Raceway, driving the No. 66 Ford for ThorSport Racing, where he finished in tenth place. He then ran the races at Pocono Raceway and Lucas Oil Indianapolis Raceway Park, finishing twenty-second and seventh respectively.

In 2025, it was announced that Fenhaus would run another partial Truck Series schedule with ThorSport in the No. 66, this time in eleven races. At Michigan, Fenhaus would score his first career pole and would earn his best career finish of third-place.

NASCAR O'Reilly Auto Parts Series On January 27, 2026, it was announced that Fenhaus would attempt to make his debut in the NASCAR O'Reilly Auto Parts Series at Daytona International Speedway, driving the No. 5 Ford for Hettinger Racing.

Personal life Fenhaus's cousin, father, and grandfather raced snowmobiles on ice oval tracks, and he started his racing career by racing snowmobiles before racing on pavement. He was inspired by drivers Tim Sauter (from watching him race at State Park Speedway) and Kevin Harvick (which is why he chose to race the No. 4 in late models and uses the same font that Harvick does in the Cup Series).

In 2022, Fenhaus graduated early from Wausau East High School and moved from Wisconsin to North Carolina (where NASCAR teams are located).
