Daniil Kvyat takes over behind the wheel tomorrow for the fourth and final test day at Jerez.
The STR9 was back on track and completed 30 laps with Jean-Eric Vergne at the wheel, which is a much more positive result than yesterday, showing that work is going in the right direction.
Jean-Eric Vergne: “It was still a difficult day, but I'd say a lot more positive than the previous two, in fact it was a massive step forward. Towards the end, we were able to complete a few laps with the power unit running well. I am pleased with the work done by the team, especially on the Renault side. After yesterday, everyone stayed calm and identified the problem. I believe we now have a good basis on which to work overnight so that tomorrow we can make even more progress.”
