Testing
If a team declares that one of their current race drivers is to be substituted by a driver who has not participated in an F1 race in the two previous calendar years, one day of track testing will now be permitted, on an approved circuit not being used for a Grand Prix in the current season. This is to avoid scenarios such as that seen in 2009 when Jaime Alguersuari made his Formula One debut with Toro Rosso having only previously driven an F1 car in straight-line testing.
In another minor change, teams will be allowed six rather than eight days of straight-line aero testing per season. They will also have the option of substituting any of these days for four hours of wind tunnel testing with a full-scale (rather than the normal 60 percent-scale) model.
