Renault headed back home with a written-off race weekend after neither of its drivers failed to see the checkered flag in Sunday's Azerbaijan Grand Prix
Jolyon Palmer's engine suffered from a misfire on the way to the grid and the issue worsened until his retirement at the end of lap 7.
Nico Hulkenberg was running as high as fifth in what was a highly eventful race, but clipped the wall and broke his front right suspension on lap 25.
The double DNF result is a set-back for the French team in its quest to for sixth place in the Constructors' standings, and one which Renault Sport boss Cyril Abiteboul was not happy with.
"A double DNF is the worst that can happen to the team both in terms of race results and in terms of championship position," lamented Abiteboul.
"We need to understand and immediately address the technical issues that prevented Jolyon to even participate, and Nico to start higher in the grid this weekend.
"We saw a highly unusual and eventful Grand Prix and we will do all we can to make sure that this will be our only double DNF of the season.
"The only positive note is that a Red Bull Racing car finished on the highest step of the podium, which, on a track like Baku, is a great reward to the efforts made in bringing extra power to our customers."
