May 7 (GMM) McLaren tested a higher front nose at the Mugello test last week.
Backmarker Marussia aside, the famous British team is the only team in 2012 to have resisted the temptation of running a high 'step' nose, in the wake of new safety regulations.
McLaren was the early frontrunner this season with its MP4-27 car, but Jenson Button and Lewis Hamilton struggled notably last time out in Bahrain.
Germany's Auto Motor und Sport said the team quietly tested the significant nose development on the final day of Mugello testing last Thursday, with test driver Oliver Turvey at the wheel.
The report also speculated that McLaren experimented with an adjustable brake duct system at Mugello, which might be used to regulate tyre temperature for the finicky 2012 Pirellis.
The system would have to be adjusted by the mechanics during a pitstop.
