That should reduce the need to harvest battery power and super clip.<\/p>\n The sport\u2019s bosses also agreed on a change to the race starts, with a new \u2018low power start detection\u2019 system developed, which will trigger an automatic MGU-K deployment to mitigate start-related risks.<\/p>\n Want to be the first to know exclusive information from the F1 paddock?
