Red Bull Racing's Daniel Ricciardo climbed back behind the wheel of the RB13 on Tuesday where he had a very successful morning, even if it wasn't the most thrilling of sessions for him.

However, the afternoon session saw an issue with the power unit in his car curtailing his afternoon session as the Milton Keynes based squad went to work to fix the issue to make sure the car was ready for today's second and final day of the test where Pierre Gasly is behind the wheel and currently sits ninth on the timesheets as the teams prepare to break for lunch.

"It was a good outing for the aero department – we did a lot of data gathering in the first hour, which all went to plan, and that's important for the guys, even though for a driver it's not the most thrilling thing, as you're just trundling around really!” Daniel said. “After that we did a few runs on the soft tyre and made a few mechanical changes, which were interesting, we then completed a couple of runs on the supersoft.”

“ I think we discovered a few things there. You do try some bigger set-up steps than you might do on a race weekend and it was interesting to see what the results of those changes were. We were planning a few long runs in the afternoon but obviously the power unit issue prevented that."
