Formula One has significantly altered its proposed ban on pit-car radio transmissions after teams raised concerns, with information on car performance allowed for the rest of the season.

F1 proposed drastic rules to prevent most radio messages due to fan disquiet that it was the teams rather than drivers that were effectively controlling the cars, with drivers altering settings at team behest and following instructions on fuel, tire and brake use.

The new rules were to have started at the Singapore Grand Prix this weekend, but following a meeting between the teams and the FIA late Thursday, it was determined that the ban on car-performance information will be put off until 2015.

However, driver coaching messages via radio will be banned immediately.
