In 2024, Michael Christensen enters his second season in the Porsche Penske Motorsport (PPM) program. He will contest the full FIA World Endurance Championship (WEC) season behind the wheel of the No. 5 Porsche 963 LMDh. Christensen will once again be paired with Frederic Makowiecki and the duo will also be joined by IMSA WeatherTech SportsCar Championship race winner Matt Campbell.

One of the early defining moments of Christensen's career happened in the fall of 2011. Going up against many other talented young drivers from around the world, he shined during a grueling selection process and was accepted into the Porsche Junior youth development program. Christensen continued to excel as he joined the Porsche Carrera Cup Deutschland in 2012. With consistently good performances and a win at Hockenheim, he grabbed his chance and climbed the ladder into the Porsche Mobil 1 Supercup.

In 2013, he promptly won the rookie classification and he claimed a race victory at Nurburgring. The strong Supercup results earned Christensen an opportunity as a Porsche works driver, beginning in 2014. In his rookie season as a works racer, Christensen promptly won the 12 Hours of Sebring.

In his first WEC season, Christensen posted three GTE Pro class victories in 2015. He continued to race in both Europe, as well as the U.S. in 2017 and the following year he broke out with a GTD class victory at the 24 Hours of Daytona before earning a class runner-up result in the Petit Le Mans season finale at Road Atlanta.
