BERLIN, Germany - Formula 1 chief executive Bernie Ecclestone has predicted that the 2013 season's runaway championship leader and Red Bull ace Sebastian Vettel's dominance of the sport could end as early as 2014Ecclestone said: "His domination will end, maybe in 2014. We're going to have completely new cars, new engines, new rules. "That will be the chance for Ferrari and Mercedes to catch up with Vettel. Next year it might not be the best driver but the best car that wins the title."ONE SEASON, SEVEN WINSEcclestone said he believed the recent jeers that have met Vettel's last two race wins in Italy and Singapore were not due to him as a person, but due to his dominance.Vettel has won the last three grands prix and seven in total in 2013, more than half the races, and leads Ferrari’s Fernando Alonso by 60 points in the standings. Alonso is 36 points ahead of third-placed Mercedes’ Lewis Hamilton.Ecclestone said: "He doesn't give Fernando Alonso and Lewis Hamilton a chance, he's as dominant as (Ayrton) Senna or (Michael) Schumacher in certain periods."
