Allez Opi-Omi!

Go Grampa/Gramma!

Original: "Go, Grampa and Grandma!" (Or, "Come on, Grampa and Gramma, (look at me!)) with "Go" in French and the rest in German.

But here "Opi-Omi" can also mean Grampa/Gramma, which is what McQueen's relation is to Gold Ship if one takes into account her real-life racehorse counterpart.
