The Enstone team has applied for permission to have an extra day on track, which would require unanimous consent from the other teams.

AUTOSPORT understands that Lotus already has the required agreement from the majority of teams and given that Mercedes was granted an extra day before this week's Barcelona test after only running for three days in Jerez two weeks ago, it is likely to get permission.

It's not yet decided whether Lotus will run before or after the next Barcelona test, which runs from March 1-4, but sources indicate that the team is confident that it will have its chassis ready after making modifications to solve a problem believed to be related to the front suspension.
