How did AJ Allmendinger get to NASCAR?

A.J. Allmendinger started his NASCAR career with Red Bull Racing in late 2006. The move from open-wheel racing to stock cars wasn't easy, and after struggling to qualify for races, he was released by the team in 2008. He bounced back with Richard Petty Motorsports, where he raced from 2009 to 2011. 

During that time, he finished third in the 2009 Daytona 500 and recorded his best points finishes in the Cup Series. Those performances earned him a move to Penske Racing in 2012, but his season ended early after he received an indefinite suspension following a failed drug test. 

Allmendinger returned in 2013 and slowly rebuilt his NASCAR career. Penske Racing brought him back for selected races, and he won two Xfinity Series races before joining JTG Daugherty Racing full-time, where he raced through 2018. He joined Kaulig Racing as a part-time Xfinity Series driver in 2019 and won at the Charlotte Roval that season. 

In 2020, he claimed his first NASCAR victory on an oval at Atlanta. A year later, Kaulig Racing gave him a full-time Xfinity ride and a part-time Cup Series schedule. He won multiple Xfinity races and gave the team its first Cup Series victory at Indianapolis. In August 2024, Kaulig Racing announced that Allmendinger would return to full-time Cup competition in 2025.
