"We now know the car is strong enough and as from 7 February in Jerez, we can start work on making it quick and reliable," a team source reported in a press release posted on the team's website.
The test will run from Feb 7-10, followed by two more sessions (at Barcelona) Feb 21-24 and March 1-4. There is no word yet as to how the testing duties will be divided up between Daniel Ricciardo and Jean-Eric Vergne.
