Formula 1 Managing Dir Ross Brawn said that F1's engine makers "will have to share some parts and technology with new entrants under proposed rule changes" for '21, according to Alan Baldwin of REUTERS. Mercedes, Ferrari, Renault and Honda between them supply the 10 teams and "there are no newcomers set to join them in two years’ time." Brawn: "The drawbridge has been pulled up and the existing suppliers don't want anyone else to come in." He said that a compromise had been found, however, that "might make it easier." Brawn: "There are regulations coming out which would mean new entrants will get support from existing entrants. There will be components and technology which will have to be shared if it is requested. There has been a recognition from the existing manufacturers that they can’t shut the door behind them." F1's post-'20 vision set out last April originally envisaged "cheaper, simpler engines to encourage new manufacturers into the sport," with Porsche and Aston Martin attending some meetings. Aston Martin CEO Andy Palmer said last month that his company "lost interest after the sport backtracked on those plans" (REUTERS, 12/14).
