Red Bull’s Italian-based rookie team said the Ferrari-powered TR7 passed the last of the FIA’s mandatory crash tests on Thursday.
According to new rules this year, the car is therefore now fit to test at Jerez from 7 February.
“(Now) we can start work on making it quick and reliable,” said Toro Rosso in a statement.
Reports indicate that Australian Daniel Ricciardo – the slightly more experienced of the team’s lineup also featuring rookie Jean-Eric Vergne – will be driving the TR7 on the opening day.
Frenchman Vergne is expected to drive on the last two days of the four-day test.
