Matt Campbell will compete for Porsche Penske Motorsport in 2023, driving the No. 7 LMDh Prototype in the IMSA WeatherTech SportsCar Championship, alongside co-driver Felipe Nasr.

In his first full season competing in the IMSA WeatherTech SportsCar Championship in 2022, the Australian-born Campbell produced four class victories on his way to claiming the GTD Pro (GTDP) class championship while racing a Porsche 911 GT3 R for Pfaff Motorsports. Paired with current Porsche Penske Motorsport teammate Mathieu Jaminet last season, Campbell scored class victories at the Rolex 24, Laguna Seca, Canadian Tire Motorsports Park and Lime Rock en route to the GTDP title. The performance earned Campbell the opportunity to compete in the No. 7 Porsche 963, with Nasr, in 2023. 

Campbell competed in seven races during the 2021 IMSA WeatherTech 
SportsCar Championship season. He produced three GT Le Mans (GTLM) class victories in his seven starts, racing a Porsche 911 RSR-19 for WeatherTech Racing. 

In 2020, Campbell raced in the IMSA season-opening Rolex 24 at Daytona and the Petit Le Man season finale at Road Atlanta. He was part of the GTLM pole-winning effort at the Rolex 24 and the class-winning finish at Petit Le Mans to close out the season.

Campbell made his debut in the IMSA WeatherTech SportsCar Championship during the 2019 season. Driving a Porsche 911 GT3 R, Campbell competed in the Rolex 24 at Daytona, along with series races at Lime Rock and Road America. He earned his first IMSA class victory with a GTD win at Road America.
