Dodge plans to pull out of NASCAR at the end of the 2012 season.

ESPN.com first reported the decision, necessitated largely by Penske Racing opting to move to Ford engines starting in 2013.

Penske has been a Dodge team since 2003 but was affiliated only with Ford from 1994 to 2002.

Ford announced Monday the Penske engines would be provided by Roush-Yates. ESPN reported the move casts doubt about the Penske Racing motor department with more than 60 employees.

Dodge was out of NASCAR from 1978-2000 before returning in 2001.
