General Motors is in the process of developing the Ecotec range of small capacity petrol engines from one litre to 1.5 litres.  These engines will be built to a three and four cylinder architecture. These engines will feature direct injection, turbo charging and alternative fuel using capability.  The engines will have modular construction and different manufacturing plants in different parts of the world can change the components that go into the manufacturing of the engine, depending upon regional demands.
