Intro:

Felipe Nasr, one of three newcomers to Formula One, clocked the fastest time on the third day of pre-season testing on Tuesday (February 3).

SOUNDBITE (English): Nico Rosberg, Mercedes

"Yeah, so it's been a good start. The goal here was to do many kilometres and start to see where the problems are with the car, reliability-wise, so we achieved that in many ways, you know. Doing many kilometres, we started to see things breaking down and that's good, because then we can sort them out before Melbourne, because our weakness last year was this reliability a little bit and that, we really need to nail it this year and we're on the right track."

SOUNDBITE (English): Daniel Ricciardo, Red Bull

(Question: Running today was curtailed by an engine problem. We've been there before with Renault, particularly at the beginning of last season. Have you got concerns that they're not ready?) "No, we came in to this test, knowing that it was a pretty big evolution from last year and we knew it would be tight. So, you know, we'd obviously love to do a hundred and fifty laps here, but we knew it would be compromised one way or the other. Yeah, we'll see. If Danny (Russia's Daniil Kvyat) can rack up fifty laps tomorrow, I think that's not a bad test for us."
