The Globe and Mail reports in its Friday edition that chief executive officer Don Walker says Magna International will likely need to build a new assembly plant if it wins more contracts to manufacture vehicles. The Globe's Greg Keenan writes that Magna and BMW announced Thursday the new version of BMW's 5 Series sedan will be assembled at Magna's plant in Graz, Austria, beginning next year. That contract, plus another to build unidentified vehicles for Jaguar Land Rover, and the extension of an agreement to make a Mercedes-Benz sport utility vehicle in Graz, will take production volume in the Magna plant up to 200,000 vehicles a year. The Graz plant, called Magna Steyr, will be at full capacity later in the decade, says Mr. Walker. He says Magna has no plans at the moment to build a new assembly facility. However, another plant would be necessary if Magna were to sign more contracts that would generate production of 150,000 to 250,000 vehicles a year. Neither BMW nor Magna would reveal how many cars Magna Steyr is expected to build, but industry sources said in January that annual production should be about 100,000. The cars will also be built at BMW's existing plant in Dingolfing, Germany.
