Mar.7 (GMM) Marussia's 2012 car will be on the Melbourne grid next weekend, after the MR01 finally passed a missing FIA crash test.
The former Virgin team's Cosworth-powered car sat out the entire official pre-season period due to a new regulation in 2012 requiring single seaters to be fully homologated before they can even be tested.
The MR01 finally made its track debut on Monday and Tuesday, due to a loophole allowing limited running on demonstration Pirelli tyres for filming purposes even when the mandatory crash tests have not been passed.
But finally, late on Tuesday, Marussia announced that the crash tests have now all been passed.
"After a challenging few weeks for the team, we are pleased to have overcome the last hurdle of the final FIA observed crash test, which we passed today," said technical consultant Pat Symonds.
"Whilst we have a lot of catching up to do, we take heart from the fact that everything is back on a more positive trajectory," Renault's former engineering director added.
