Late Renault retirement in Bahrain GP was 'brutal' - Hulkenberg

The German had fought his way up to sixth - which included battling through a "war zone" of an opening lap - but was robbed of a finish when he suffered an engine issue on the approach to Turn 1 just after starting his fourth-last lap.

Team-mate Daniel Ricciardo then stopped at the same corner seconds later with what Renault later confirmed was an MGU-K problem.

Those events left Renault shellshocked, and Hulkenberg said he too found it hard to accept a good result had been taken away so quickly.

"In my mind I had it booked already," he said. "But it just shows you have to bring it home [over the] full race distance.

"Without that, three laps, I was controlling everything. I had a gap to [sixth-place finisher Lando] Norris and everything was fine.

"It came also without any signs or problem before. It just happened from one moment to another.

"Obviously it's a bitter one, hard to swallow. A brutal moment that can happen in racing.

"But on the positive side we had decent pace in the car today. Just yesterday and today the problems prevented really good results."

Hulkenberg managed to charge through the field from 17th on the grid, after surviving what he described as a crazy opening part of the race.

"Lap one was like a war zone," he said. "It was crazy.

"[There were] cars all over the place, contact, sparks, parts flying around - I got a big hit on the helmet from a part as well.

"Everything was in that race. It was a spectacular race to be in.

"I did a lot of overtaking which was fun. It would have been really nice to reward myself and the team with those points, but we just need to bounce back another time."

Team principal Cyril Abiteboul said Renault had "previously encountered" the issues it experienced late on, which he said were becoming "increasingly frustrating and unacceptable".

"After a very intense winter, it's been a very bad start to our racing season," said Abiteboul.

"Similar to Melbourne, our qualifying in Bahrain was massively compromised by minor electronics issues, which impacted both cars.

"Our race today came to a sudden stop so close to the finish. These are issues we have previously encountered but something we were unable to rectify in Bahrain.

"These problems are increasingly frustrating and unacceptable as both cars have shown very good competitiveness both over one-lap and race runs.

"Nico delivered another outstanding drive from seventeenth to sixth.

"Daniel is building on precious experience in the car, and despite good race pace, his strategy gamble didn't work out.

"Daniel will continue his familiarisation in the car during this week's test conducting performance-related work.

"We must react and shift our focus on reliability."
