Mar.11 (GMM) HRT on Friday became the last formula one team to reveal its 2011 car.

But the F111, designed in-house by the Spanish team after the collapse of a technical deal with Toyota, may not actually run at the Circuit de Catalunya on Friday due to delayed spare parts.

That would mean Hispania, featuring drivers Tonio Liuzzi and Narain Karthikeyan this season, will have just one full day of testing before the season opener in Australia in two weeks.

The car, shown to the world's media in the Barcelona pitlane, does look different to the sluggish 2010 contender, and features an all-new white and red livery.

On track, Michael Schumacher was impressing at the wheel of Mercedes' fully-updated Mercedes car, beating Sergio Perez's Thursday best time despite using only the soft Pirellis -- not the super-softs used by Sauber' Mexican rookie.

"We've definitely moved forward," team boss Ross Brawn told the BBC. "Whether it's enough we won't know until Melbourne."

Elsewhere in the F1 world, McLaren's executive chairman Ron Dennis was banned from driving on the roads for six months following four recent traffic offences in the UK.

The Surrey Advertiser newspaper said the 63-year-old's latest offence involved running a red light.
