Daniel Ricciardo’s string of bad luck continues as he faces a five-place grid penalty for this weekend’s Brazilian Grand Prix.

The Australian, who suffered yet another mechanical failure during last round’s Mexican Grand Prix, was forced to change his turbo after it was found to be damaged by fire extinguisher chemicals that a marshal moved on to douse a small fire.

It means the Renault-bound driver can start no higher than sixth this Sunday as he looks to finish his outgoing season on a high in his Red Bull outfit.

“Obviously the marshals are doing the prudent thing, and they have seen a bit of smoke,” said Red Bull Racing Team Principal, Christian Horner on Sky Sports F1.

“You can see flames coming out of the back there, so you cannot blame the marshal really, he is putting out a fire.

“But then he has rammed a load of fire foam up the exhaust and it has then solidified in the turbo, and that was the end of that. It ruined the turbo.

“The other turbo that Daniel has in his pool was on the engine that failed in Austin, and Renault was saying that every time they have run a turbo when they have had a failure like that, they normally stop after 400km. So, we don’t really want to put him in that position.”

Since the 29-year old’s Monaco triumph earlier in May, Ricciardo has fallen absent to the podium while enduring six DNF’s, with back-to-back retirements on two occasions. His Dutch teammate Max Verstappen, however, has claimed fortune with dominant victories in Austria and most recently, Mexico City.
