SAO PAULO -- Daniel Ricciardo's run of rotten bad luck is showing no signs of coming to an end any time soon.
The Australian driver will serve a grid penalty this weekend after Red Bull was forced to change the turbocharger in his Renault engine. It's the sixth turbo he's used this year, above the allotted amount in the regulations, meaning he will serve a 10-place grid penalty for Sunday's race.
Ricciardo suffered a heartbreaking double retirement at the U.S.-Mexico double header while running in promising positions -- he had taken pole position in Mexico City before the reliability issued occurred on Sunday.
