He remained with the team for the 2008 season in the newly-formed Formula BMW Europe, where he scored 11 podiums including one victory, but was beaten to the title by teammate Esteban Gutiérrez.

[8][9] Podiums came often that year, as Wittmann scored 13 in 27 races and took five wins, including victories at the Pau Grand Prix and two triumphs at the Norisring.

He would return to the top step at Zandvoort, defending well against fellow BMW driver António Félix da Costa, but was only able to follow this up with a podium in Moscow and one at Oschersleben, eventually ending up sixth in the standings.

[29][30] During the summer of 2015 meanwhile, Wittmann was able to test the Toro Rosso STR10 Formula One car at the Red Bull Ring, garnering praise from race engineer Phil Charles for his technical feedback, cleanness, and long-run rhythm.

[35][36] The title fight would become tighter following a disqualification for a technical infringement in Hungary however, whereafter Wittmann led the standings by just 14 points to Edoardo Mortara.

[40] He would return towards stronger results in the latter half of the campaign, scoring four podiums in the final five events, though he also garnered attention for his repeated critique of Audi's drivers and their driving etiquette over the team radio.

[42] In 2018, the German was comprehensively beaten in the standings by Gary Paffett, René Rast, and Paul di Resta, coming home fourth overall after winning in Hungary and defending well against Mortara to take the spoils at the Norisring.

[50][51][52] Unfortunately for the German, he was only able to score two podiums in the remaining three events while Rast and Müller pulled away with multiple victories; thus, Wittmann ended the season third in points.

[57] Despite being the team's only driver, Wittmann found himself fourth in the standings after the first half of the season, finishing every race inside the top eight and winning at Zolder.

Meanwhile, Wittmann would also score his maiden podium at the 24 Hours of Nürburgring, finishing second for Rowe Racing alongside Martin Tomczyk, Sheldon van der Linde, and Connor De Phillippi.

[70][71] In the GTWC Endurance Cup meanwhile, the ROWE trio won the season opener at Monza and came out on top at the prestigious 24 Hours of Spa.

Wittmann would be racing on two fronts in 2024, as he became part of Schubert Motorsport in the DTM alongside fellow champions René Rast and Sheldon van der Linde, and was named as one of BMW M Team WRT's six drivers in the Hypercar category of the FIA World Endurance Championship, partnering Raffaele Marciello and Dries Vanthoor in the #15.
