INDIANAPOLIS -- Dale Coyne Racing and Vasser Sullivan Racing announced Friday they will end their IndyCar Series partnership.
The two teams had worked together for the past four seasons.
Coyne's team issued a statement acknowledging Vasser Sullivan wanted to focus on its sports car entries, though the Vasser Sullivan team said it still hopes to compete on North America's top open-wheel circuit.
"We've had a great and successful time with our partners at Vasser Sullivan Racing and we appreciate everything Jimmy and Sulli have done and brought to the team and our No. 18 entry," Coyne's team said.
