KERS "a potential risk" for Red Bull

For the whole of the weekend, Red Bull had been keeping very quiet about their KERS outfit. Why weren't the reigning world champion constructors using it during qualifying, what were all these rumours about a 'mini KERS' for the start and did they even have a hybrid system on board the RB7 at all?

"We didn't have KERS in our cars this weekend," revealed team principal Christian Horner in an interview with the BBC.
"We didn't want to tell anyone. If you look at the start of the race, it seems it wasn't necessary anyway." Pole-sitter Sebastian Vettel easily shook off the pursuing Lewis Hamilton to claim a convincing start-to-finish victory in Melbourne.

Horner admitted that the Red Bull KERS system would be causing the team a few more headaches yet. "We were a bit nervous about discussing it before the race. We used it on Friday and we were unhappy with the reliability. We felt that it could be a potential risk, so we removed it from both cars and didn't use it for the whole of Saturday and Sunday," said Horner, explaining the secrecy surrounding the hybrid system.

Although KERS represents an interesting advance in engineering, Horner said that star designer Adrian Newey saw no good reason to build the RB7 around the system: "KERS would have to fit in with Adrian's aero package, and that would have been a bigger challenge for us."

Red Bull will use KERS at some tracks - Marko

There will be other grands prix at which Red Bull does not use KERS this season, Helmut Marko has revealed.

After all the talk about 'mini-KERS', it emerged on Sunday that the reigning champions had actually removed the energy recovery systems from both cars before Sebastian Vettel dominated qualifying and the Australian grand prix.

"I guess that we will use it (KERS) at tracks that have a long straight," Red Bull motor sport boss Marko said on German television RTL.
