SUZUKA - So dominant is Sebastian Vettel that the German said he would race without the power-boosting KERS system in Sunday's Japanese Grand Prix if Red Bull mechanics could not fix the problems that plagued him during qualifying. The fact that Formula One's runaway championship leader lapped second quickest behind team-mate Mark Webber at Suzuka on Saturday is testament to Vettel's prodigious talent and unrivalled pace. "Obviously we had an issue with KERS (Kinetic Energy Recovery System) in the morning free practice, causing us to abort (the session) prematurely and change all the batteries," said Vettel, who will secure his fourth successive world title if he wins on Sunday. "We have to find the issue and solve it," said Vettel. "That's plan A. If that doesn't work we have to race without KERS."–AFP
