UPDATE 2-Peru awards $5.66 bln subway project to sole bidder
(Adds project cost from Proinversion, recasts first sentence and headline to focus on companies with biggest stakes)
LIMA, March 28 (Reuters) - A consortium led by European firms Finmeccanica and ACS won a contract for a $5.66 billion subway line in Lima after competitors unexpectedly dropped out of the contest last week, Peru's state investment agency said on Friday.
Consorcio Nuevo Metro de Lima will build and maintain the mostly underground 35-kilometer (22-mile) line in a 35-year private-public concession, state investment agency Proinversion said.

Spanish builder Iridium, owned by ACS, controls 25 percent of the group, which also includes Spain's FCC and Peru's Cosapi, Impregilo said.
Two other consortiums, including one formed by Brazilian construction giant Odebrecht and Peru's biggest builder Grana y Montero , failed to submit bids last week as expected, sparking concerns that the auction might be flawed.
Proinversion said those groups pulled out after the government refused to raise the project's $6.62 billion cost ceiling.
