F1: Vettel unfazed by latest rule changes
Sebastian Vettel has brushed aside the latest regulation changes that could affect his chances of retaining the Formula One world title.
Since the last grand prix in Canada, the FIA have outlawed engine mapping changes - tuning the engine to provide extreme performance - between qualifying and a race.
And from the British Grand Prix in a fortnight's time, off-throttle blown diffusers, using exhaust gases to also aid performance, will be banned.
The general feeling in the paddock is that the changes have been made by FIA technical delegate Charlie Whiting in order to slow down Red Bull and Vettel, who have dominated the current campaign.
However, Vettel, who has six poles and five wins from the seven races this year to open up a 60-point gap in the standings, is unfazed.
"Engine mapping is something everyone has played around with, especially this year," the 23-year-old German said.
"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.
"I don't think the team are hiding something from me, so there's no secrets. I can assure you there is nothing special going on from Saturday to Sunday."
Team-mate Mark Webber is also of the same mind, although he feels for all concerned in F1 it would have been better if the FIA had dealt with the matter at the end of the season.
"It will be the same for everybody. We just need to adapt again and get used to it," the 34-year-old Australian said.
"Our team are used to adapting to a change in the regulations which I don't think will turn the field upside down.
"Obviously it would have been cost effective to know this before the season started.
"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 anticipated Red Bull have more to lose than anyone, but team principal Christian Horner believes "it's impossible to predict."
Horner added: "We know what benefit we see, but we don't know what benefit others see. In reality it will affect the front-running teams a very similar amount to be honest.
"Then there are other teams who have exploited the concept more and very clearly designed their cars around it, so I can only envisage that they must be highly frustrated by it.
"It is slightly confusing, with the technical directive, that it wasn't addressed at the end of the year going into next year, why it's been done mid-season.
"At the end of the day it's the same for everybody and we'll deal with it at Silverstone."
