Renault's director of operations Remi Taffin says it has been painful to accept the fact his team has failed to win a single race in the 2015 F1 championship, if it misses out on the top step of the podium in Abu Dhabi.
In a season which has seen the French power unit manufacturer badly fall out with the teams it supplies, Red Bull and Toro Rosso, while having already lost Lotus who switched to Mercedes engines for 2015, Renault admits it has been a thoroughly underwhelming campaign.
Due to the Yas Marina circuit's characteristics with its long 1.7km straight the underpowered Renault engine is expected to once again struggle against the likes of Mercedes and Ferrari and Taffin says it would be a bitter blow to finish the season without a win as a supplier.
“After a long season we reach the final race of the year in Abu Dhabi. By our own standards it's not been as successful as we could have hoped and it will hurt if we finish the year without a win,” Taffin said. “But we have learnt a lot and there are also some strong steps forward that will consolidate us in future.”
Reflecting on the season as a whole, Taffin is upbeat that Renault has cured the majority of its reliability issues which plagued its start to 2015 and believes it has also closed the gap on its rivals in terms of performance.
“After a shaky start to the year we have consolidated reliability and each part is much more robust than last year,” he added. “Performance-wise we are also closer to the competition and know that in some circumstances we are able to challenge for the podium.
“Naturally challenging for wins is the next step in our recovery and the information learnt this year will help us get closer to achieving this aim.”
Renault is expected to complete its buy-out of Lotus in the coming weeks, while potentially salvaging a deal to supply Red Bull in 2016 after the team confirmed it will be on the F1 grid next season.
