The potential extension of DRS overtaking zones this year will be decided on a circuit by circuit basis.
That is the claim of Auto Motor und Sport, even though the extension of the zone in Barcelona proved a success.
After Russia, where the only overtaking move was a Sauber team order, the drivers pushed the FIA to have the Barcelona DRS zone extended by 100 metres.
"Without that, overtaking would have been harder. It gave you 4 to 6 metres more," said winner Lewis Hamilton.
Indeed, the report said that in the end, there were 18 overtaking moves in Barcelona, not including more near-passes and duels.
But correspondent Michael Schmidt said: "The FIA wants to look at DRS zones on a case by case basis and extend them only where it makes sense."
