Webber had chassis problem in Australia - Marko
Helmut Marko has suggested Mark Webber suffered with a chassis problem in Melbourne.
The Australian was almost nine tenths off dominant teammate Sebastian Vettel in qualifying, before finishing almost 40 seconds down in Sunday's 2011 season opener.
"Mark had some problems with the chassis," Red Bull's motor sport director Marko said on German television RTL.
"With him, neither the hard nor the soft tyres really worked. His tyre wear was also significantly greater than Sebastian's," he added.
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.
