Initially with its own Williams Hybrid Power company, the Grove squad had developed a flywheel KERS unit, but later switched to a battery-powered system for its FW33 challenger.
However, ongoing reliability concerns might see the unit temporarily cast aside until the problems can be resolved.
“We need to decide quickly what we are going to do,” Rubens Barrichello told Dutch website f1today.nl.
“I hope we do not conclude that we have to race in Melbourne without KERS, but it is possible,” he added. “It is an uncertain factor for us; one day it gives us no problems and the next day it gives us hundreds of problems.”
But Q3 issues aside, the Grand Prix veteran believes that the new car can deliver “Q3 and a good number of regular points” as he enters his eighteenth consecutive season in the sport.
Meanwhile, there are also reports that Swiss watchmaker Oris has increased its sponsorship commitment with the team, in a deal that will see its logos have a greater presence on the livery of the FW33.
