Renault drivers Kevin Magnussen and Jolyon Palmer both retired from the British Grand Prix due to worsening gearbox problems with the RS.16.
Renault endured another troublesome performance at Silverstone as neither Magnussen nor Palmer challenged for the top 10 before retiring.
Palmer was also skewered by an issue in the pit lane as neither driver reached the chequered flag.
"We tried our best but unfortunately we were just not quick enough today," said Magnussen.
"We suspected something might be wrong with the gearbox towards the end of the race so retired the car as a precaution."
Palmer added: "It was going reasonably well on the wet tyres at the beginning of the race and then we did a good stop for the intermediate tyres.
"Things were looking up: I got ahead of Kevin and I was catching Romain Grosjean. When I pitted for slick tyres, I had a green light to go but the rear right wasn’t finished and I’d already started to leave the box.
"From then on I lost about a minute and then received a 10 seconds penalty for unsafe release. What happened was unfortunate but it could happen to anyone up and down the pit lane.
"We retired the car as there was a strange feeling with the gearbox, more as a precaution as at that stage we were two laps down."
