F1 technical director Ross Brawn says proposed changes to engine regulations could be put on hold until 2021. Big changes have been planned to the engines to try and attract more suppliers to the sport, including Porsche.
The key change would see the abolition of the MGU-H unit, which converts heat energy from exhaust gases into electrical energy, providing around 60% of the car’s energy from electricity.
However, it seems many in the paddock are not keen on the proposals, with Mercedes boss Toto Wolff saying it is wrong to change the engine rules so dramatically.
And Brawn admits it has given Liberty Media food for thought on where they should go with the changes.
“We want to devise new technical rules for the engines, with which we can arouse the interest of new manufacturers and at the same time keep the existing manufacturers on board,” he told reporters.
“That’s why I think we should think about the timing,” he added. “I’m not sure if 2021 is the right date or whether we should wait until we can be sure that extensive adjustments will also bring fresh blood into the sport.”
