Renault insists that the problems that have struck its Formula 1 teams are fixable by the next Bahrain test.
The French car manufacturer has had a difficult time at Jerez in Spain this week, with its teams struggling with reliability. Most in the spotlight has been Red Bull, with the reigning champion outfit completing just 14 laps over the course of the first three days.
But as work continues at Renault's Viry-Chatillon base on Thursday night to implement solutions, the company's F1 engine chief Rob White has made it clear that its problems are curable by Bahrain.
In the meantime, Renault is focusing on workaround solutions to the software issues that have blighted its running this week so its teams can complete valuable mileage on Friday.
"We are extremely confident that the problems we have experienced can be dealt with," White said. "We don't have a single minor problem or indeed a big howler that is causing the trouble.
