From this weekend’s European Grand Prix, Formula One teams will no longer be allowed to change engine maps between qualifying and the race.

This will immediately eradicate special qualifying settings, used by the teams, where Red Bull in particular have proved very successful.

It is believed that some teams had been running extreme engine maps for qualifying to maximise the cars performance over a shorter run.

These settings are then changed for the race as over a longer distance the cars risk reliability of engines and could also burn too much fuel.

F1 technical chief Charlie Whiting informed the teams earlier this week, but while many believe the change could affect Red Bull the most due to their dominance in qualifying, their drivers do not think they will be overly affected.

‘I think it’s something that everyone was playing around with, especially this year, It makes a difference to everyone, but I don’t think it makes a bigger difference to us than others. It’s the same for all of us, all the teams.’ Sebastian Vettel told Autosport Magazine, while Mark Webber added: ‘It is not a trivial thing to throw in the middle of the season for teams, but they will adjust. Everyone is in the same boat. It is the same for everybody. We are not overly concerned. It is not a cheap exercise to make adjustments off the back of it.’

Formula One teams will have to adjust again to another tweak in the regulations next month.

From the British Grand Prix the use of blown diffusers while ‘off-throttle’ will also effectively be banned.
