Max Verstappen says he isn't concerned by the fact the same problem forced him to stop twice during Wednesday's running as he still managed to rack up 101 laps – the most of any driver.
Verstappen's running on the sixth day of pre-season testing was interrupted twice, with both issues related to the power unit. However the Dutch driver is confident the problem won't recur during the season as Renault have already identified a fix.
"I didn’t run out of fuel [when he stopped on-track], we were two laps short of the race distance, we got a lot of data but unfortunately we had to stop, similar issue to what made us stop this morning.
"But in one way I’m also quite confident because the Renault boys, I think they already have some plans in place to change that part for Melbourne anyway, so it should be alright."
He added: "I always stay very positive and try not to think about it [problems] too much, that’s what testing’s for – to challenge all the parts and then see how good they are and where you can improve so for sure today we learned a lot today and that’s positive for the future."
Overall Verstappen says he's comfortable with the car which has shown small improvements between the two tests.
"Just a little bit better balance to be honest, always try to improve. We're heading in the right direction, it's more enjoyable to drive.
"It’s smooth balance, a predicable car, when you turn in you know exactly what the car is going to do so that’s positive."
