F1 to clarify test ban amid Ferrari criticism

The testing regulations will be clarified amid concerns Ferrari breached the "spirit" of the in-season ban.

Red Bull's Christian Horner this weekend accused a "naughty" Ferrari of breaching the "spirit" of the agreement by testing its new exhaust layout at Fiorano last week.

Ferrari argues that the run was allowed because "filming and promotional" activities were taking place, and FOTA chairman Martin Whitmarsh on Saturday said the teams association will react.
