General Motors UK offshoot Vauxhall has officially opened its new Supply In-Line Sequencing (SILS) building at its Ellesmere Port plant in north-west England. In one of the most complex automotive supply chain management projects in Europe, the warehouse - the size of more than five football pitches - will be operated by global logistics company Ryder plc to support production of both the Astra and Vectra ranges. The new Vectra, based on GM's Epsilon platform, has been transferred from the company's Luton factory which will be closed once production of the current model ends in March.
