Dennis welcomes new testing deal

"The testing agreement creates definition, but meaning what we have agreed to do and when, but as regards to the level of cost saving I would have liked to have seen, it has not really achieved that," Dennis said.

"But it is much better to have it that not have.

"It at least eliminates high cost testing, which was already creeping into the equation - i.e. intercontinental testing.

"What we have done is take on the request of the drivers to ensure the circuits are completely or close to completely compliant with the safety aspects of testing.

"That is the recommendations from (FIA medical chief) Gary (Hartstein)."

A provisional deal is believed to have been struck between the teams, although the agreement will only stand if all of F1's 11 teams approve the limitation.

Ferrari, who last year stood alone in refusing to sign up to the 30-day limit, have fallen in line with their rival teams this year.

Although the deal is yet to become official, Dennis said all the key teams have signed up.

"It was agreed verbally and when it passed through my desk it was two-thirds signed, it had the key names of it at the time," Dennis said.
