Carlin's Jean-Eric Vergne achieved his objective of hearing the Marseillaise played out at his home round by taking a dominant fifth Formula Renault 3.5 victory of the season at Paul Ricard.
The Frenchman led every lap from pole, and as a result of the 25-point maximum score closes to within 14 points of team-mate Robert Wickens' championship lead.
"The ambiance in the team is still quite good," said a delighted Vergne. "I haven't seen any black eyes yet! At the moment Robert and I are still sharing data and I expect that to continue until the end of the season. We remain friends off the track, but on it is a different story."
Epic Racing's Albert Costa had his most competitive drive in the category to date, finishing just one second adrift of Vergne in second. However, the Catalan was unable to close within sufficient distance of Vergne to mount an overtaking attempt.
Wickens secured the final place on the podium in what was a processional race among the top three.
Third qualifier Brendon Hartley (Gravity-Charouz) provided some excitement after slipping to fifth on the opening lap, owing to a problematic up-change away from the line.
The Kiwi lost considerable time following Alexander Rossi, the Fortec man's race severely compromised by picking up a piece of front wing that lodged in his sidepod.
Hartley was five seconds adrift of Wickens when he finally passed Rossi at Signes on lap seven, but a series of fastest laps would bring Hartley to within half a second of Wickens and a podium finish, while Mofaz's Jake Rosenzweig took advantage of the manoeuvre to demote Rossi a further position.
ISR's Daniel Ricciardo had an eventful race. The Australian dropped behind Rosenzweig to seventh in a slightly wild start, and circulated in a group bunched behind Rossi.
On lap 10, Ricciardo and Rossi went wheel-to-wheel through the final sequence of corners. Ricciado had overtaken the Californian racer at Virage du Lac only for Rossi to recover the position at the final corner, Virage du Pont.
Having survived a trip across the run-off on the exit of the corner, in order to be certain of avoiding a collision, Ricciardo grabbed sixth place at Signes two laps later.
Fifth was secured at the same spot three laps from home, but the pass was made tense by Rosenzweig briefly edging Ricciardo onto the blue rumble strips along the Mistral straight.
Wickens still leads the championship on 213 points, Vergne is second on 199 and Costa has consolidated his third place with 138.
