Fiat Chrysler (FCAU) - Get Report has agreed to a deal to supply Google's (GOOGL) - Get Report Waymo self-driving vehicle arm with a fleet of thousands of additional Chrysler Pacifica minivans.

Waymo currently has 600 Fiat Chrysler minivans in its fleet. The two companies declined to disclose exactly how many vehicles were sold or at what price.

Waymo will open its autonomous ride-hailing service to the public starting in Phoenix later this year, an endeavor that the Pacifica hybrid minivans will support as the program is expanded to more cities. 

Fiat Chrysler has furnished Waymo with 600 cars so far. 

Waymo's partnership with Chrysler isn't exclusive. The company also has a fleet of self-driving Lexus RX SUV's, but the company appears to be fazing out those vehicles in favor of Fiat Chrysler's fleet. 

"In order to move quickly and efficiently in autonomy, it is essential to partner with like-minded technology leaders," Fiat Chrysler CEO Sergio Marchionne said in a statement. "Our partnership with Waymo continues to grow and strengthen; this represents the latest sign of our commitment to this technology."
