RED BULL BOSS CHRISTIAN HORNER has rejected assertions the team will introduce its Renault-built KERS system for the Belgian Grand Prix at Spa.
The system was initially dismissed as unnecessary and ineffectual during the early rounds of the season, with many teams dropping it in favour of added ballast.
However, McLaren?s recent KERS-inspired success has forced a rethink of its potential benefits, reviving interest among the top teams and stimulating speculation Red Bull would incorporate the system in future rounds.
While Horner admitted Red Bull is considering the option of fitting KERS to its cars for Monza, he said the team is confident its car will be on the pace at Spa even without the system.
?Spa is not so different to Silverstone and we had a strong car there, so to introduce KERS at this stage could only be disruptive," he said.
"We will make a decision for Monza after Spa. It would be the Renault/Red Bull KERS one that was developed at the beginning of the season. We will continue to look at it.?
Following the Valencia event, Red Bull have fallen further behind the pace of Brawn GP in both constructor?s and driver?s championships, with Jenson Button increasing his lead over Mark Webber to 20.5 points.
Button?s closest challenger in the title race now is teammate Rubens Barrichello, who broke a five-year drought in winning the European Grand Prix.
But the Briton is still wary of Red Bull?s pace and expects the Milton Keynes outfit to be dominant at Spa, whose long sweeping turns are likely to suit the Adrian Newey-designed machines.
He said: ?(Red Bull) are going to be quick for sure over the next few races, especially the next one at Spa, although I don't think the McLarens will be as quick as they were here.?
