Daniel Ricciardo rues DNF in Mexico

Daniel Ricciardo endured a day to forget at the Mexico Grand Prix on Sunday, retiring after only six laps as his Red Bull teammate Max Verstappen won the race.

Ricciardo was forced to start from 16th on the grid after taking a penalty for a change of power unit on Sunday morning.

And then, as Verstappen streaked away to take the lead and victory, the Australian was struggling to survive before exiting with a turbo failure.

“Obviously, the weekend turned to crap,” he said.

“I did what I could at the start – it was pretty close, there was a bit going on – but I made quick progress.

“I told Helmut (Marko) this morning that I’d get up to seventh by the end of the first lap. I was a couple of laps off I think, but we got close.

“We put the new unit in, but something went wrong. Not really sure what it was or where that puts us for Brazil.”

It was a dreadful weekend for Renault with several engine failures on Friday and Saturday, while Nico Hulkenberg, Carlos Sainz and Toro Rosso’s Brendon Hartley were all hit by mechanical failures on Sunday.

All the issues appeared to be linked to Mexico City’s specific high-altitude environment.

“There’s certainly something fundamental going on,” Ricciardo added.

“We’ve been coming to Mexico the past few years so there shouldn’t be any surprises, (but) I know the altitude and temperatures have been hard to stay on top of this weekend.

“I don’t know if it’s this year’s spec of engine which is struggling up here – obviously it is, but why we’re not sure.

“So, it’s been a pretty grim weekend for a few of us.

“It’s a shame to be out early again, so I guess it’s a bit of what Max experienced early in the year – yeah, it’s not so fun."
