Sebastian Vettel isn't too worried about Red Bull's lack of running in Jerez, saying testing is the time to have problems.
The German and his team-mate Daniel Ricciardo managed just 21 laps over the course of the four days at the Spanish track.
Hampered by engine issues and overheating, Red Bull eventually called an early end to the test.
But rather than worry about it, Vettel is adamant testing is the perfect time to have issues.
"Other teams drove more miles, which is important because everything is still new," he told Sports Bild..
"But," he added, "it is better to have the problems now in the test than later in the race.
"I hope that Bahrain is better."
Weighing in on the engine issues Renault experienced in Jerez, the Red Bull racer said: "We must not underestimate this, the new drive units are a huge challenge.
"Everything is still completely new.
"I believe that both Renault and us will solve the Jerez problems but there is no guarantee that another part will go."
