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.
