Last year, BMW announced it would build its new i8 engine for hybrid sports cars alongside the current production of gasoline and diesel engines (pictured above). This is part of a £250million investment in its UK sites.
Engineers will have carried out their own cost/performance benefit benchmarking work across the board of processes and components, such as assembled camshafts (e.g. Krupp Presta) versus cast or forged camshafts (e.g. Mahle); and checked out vendors' products (e.g. for diesel fuel injection Bosch, Delphi and Siemens VDO). And then be satisfied with the results.
