F1 manufacturers to hold engine rules summit
Amid concerns that development restrictions and homologation deadlines are freezing in performance advantages too much, the sport's manufacturers have been called to discuss shaking things up to help make a more level playing field in the sport.
It is understood that teams bosses and senior engine representatives from all four of F1's car makers will be in attendance in a get-together that could have big ramifications for the competitive order in 2016 and beyond.
For if there is scope to allow Renault and Honda to make the gains they need to make a big leap forward in performance over the winter, then it could have an impact on Red Bull's engine plans.
One of the key issues at the moment is that a loophole in F1's engine regulations that allowed teams to conduct in-season development this year has been closed off for 2016.
That means all the manufacturers will have to lock down their engine designs for next season by February 28 – which is currently just a few days after 2016's first test has taken place.
Honda, Renault and Ferrari are eager for the rules to be freed up, either by allowing restricted in-season updates or even ditching development restrictions altogether.
While Mercedes could stand firm and block any changes to the rules to ensure it maintains its advantage, Motorsport.com understands it is open to a situation that would allow its rivals to catch up to a limited extent.
It is well aware that locking in the significant advantage it has over Renault and Honda at the moment is not good for F1, and that the sport overall would benefit from closer battles at the front.
However, Mercedes has to be careful in allowing too much freedom for its rivals, because there is a danger that closest contender Ferrari would utilize any update avenues to lift itself to the top of the order.
That is why there are some proposals being put forward to impose limits on dyno testing to prevent manufacturers' costs getting out of control. More at Motorsport.com
