Kevin Magnussen was handed a 10 second time penalty and two points on his license following last lap contact with Renault team-mate Jolyon Palmer in Spain.
Stewards deemed that Magnussen was culpable for edging Palmer wide at Turn 13 and went on to classify in 14th place.
The sanction dropped Magnussen to 15th spot, behind Sauber's Felipe Nasr.
"We had decent pace on the Soft tyre but on the Hard and the Medium – especially the Medium – we were weak," he said.
"It wasn’t a good day for me and I’ll be working closely with the team to understand why we weren’t able to deliver."
Palmer was more upbeat after delivering what he perceived to be the best performance of his short Formula 1 career.
"I think that was probably the best race I’ve done in terms of pace and performance," he said.
"The car was feeling okay, we were battling tyre degradation a bit but it was managable. It’s a bit disappointing not to finish in the points but for myself, I’m happy."
