Mercedes executive technical director Paddy Lowe has described as "absurd" the possibility of changes being made to the latest regulations for the 2015 Formula One season.

Despite the criticism of the new 1.6-litre V6 turbo-charged power unit following the opening two grands prix, Sunday's action-packed race in Bahrain halted in their tracks all the negative comments.

In the build-up to the event there were suggestions of shortening the races or increasing the amount of fuel being used to guard against "taxi driving" as declared by Ferrari president Luca Di Montezemolo.

But FIA president Jean Todt has made it clear there will be no quick fixes for this season, other than - for entertainment purposes - the likelihood of raising the decibel levels of the current cars given they are far quieter compared to their old V8 counterparts.

The likes of Ferrari and Red Bull, however, could attempt to push for changes for next season, but Lowe believes that would be a backward step for the sport.

"Jean has taken a very sensible line," said Lowe, whose team have made a dominant start to the new campaign, with Nico Rosberg winning in Australia and Lewis Hamilton in Malaysia and Bahrain.

"There were things being talked about in the last weeks and days that were just completely unrealistic.

"The first suggestion was we need 110 kilograms (of fuel). Has anyone realised you couldn't fit 110 kilograms into these cars? Ah, oh dear!

"Then there was talk of making the races shorter. Can you imagine selling that concept to the public?

"It would be like saying 'We've decided people aren't fit enough these days and marathons are only going to be 25 miles, not 26'. The messaging around that cannot be contemplated.

"So I hope all of that, and this ridiculous talk of fuel saving, can be put behind us.

"In Bahrain the guys were racing from beginning to end, and it was a completely normal level of fuel saving."

When asked about the possibility of their rivals pushing for changes for next season, Lowe added: "I don't even think that makes sense.

"Formula One is about developing technology, setting stretched targets. I would say the 100 kilograms for the race and 100 kilograms per hour are actually perfectly-judged numbers.

"If that's a stretch for other cars, it's a stretch they should be reaching out to.

"The nature of F1 is to push technology to the limit and beyond. The idea of backing out of that for next year is absurd to me.

"If anything the point of Formula One would be to stretch it further. Maybe next year it should be 95 kilograms for the race."
