Andretti Autosport's interests will expand to include a Global Rallycross entry in 2014, representing Volkswagen.
Team principal Michael Andretti confirmed the plans as part of the team's season launch in Indianapolis on Monday, although full details of the program are still yet to be announced.
The Global Rallycross deal will add another facet to Andretti's increasingly diverse racing activities.
In addition to its flagship IndyCar and Indy Lights operations, it also recently became the first US-based team to sign up for the planned FIA Formula E championship.
It will also continue to field entries in Pro Mazda.
