Formula One's managing director of motorsport, Ross Brawn, has labelled the gap between the sport's top three teams and the rest of the field "unacceptable".
Mercedes, Ferrari and Red Bull have won every race in Formula One since the start of the 2014 season and the performance gap between those three and the rest of the field is rarely under a second per lap. Force India's Sergio Perez is the only driver outside of those three teams to finish on the podium this year, at the Azerbaijan Grand Prix in April, and Renault, which finished fourth in the constructors' championship, was 297 points shy of Red Bull in third place by the end of the year.
