Bruno Senna will drive for Renault on Friday practice in Hungary

The Brazilian, who made his Formula 1 racing debut with the Hispania team last year, will get a one-off opportunity at the Hungaroring.

Senna joined the team in February as a reserve driver and Hungary's outing will be his first in a grand prix weekend with the team.

"I'm really excited to be driving in FP1 at the Hungaroring," said Senna.

"It's not very often you get these opportunities with big teams, and I'm very grateful for getting this chance. Hopefully I can do a good job and show the team the potential I have, and help us move forward.

"I've done some productive work in the R31 already this year - though never during a race weekend - so I know the car layout well and I'm confident it will be a smooth transition. I'm looking forward to working with the team during the session to ensure a good car set-up for Nick when he resumes driving in FP2."

Team boss Eric Boullier added: "We feel now is the right time to give Bruno a chance to drive for us during a Free Practice session. Although he's done some mileage with our R29 and R31 already this year, driving in a Friday session will provide him invaluable experience with the R31 during a race weekend.

"It will also give us with a chance to see how Bruno adapts to driving during a competitive practice session. As of Free Practice 2, Nick will return to the car for the remainder of the weekend alongside Vitaly."
