Summary

After the successful introduction of the 2,2-L ECOTEC engine with gasoline direct injection in 2003 for use in Opel vehicles, General Motors now introduces the 2.0-L ECOTEC turbo engine with direct injection and dual continuously variable cam phasing in the Model Year 2007 Pontiac Solstice GXP. These technologies help the ECOTEC engine produce more power with excellent response, while maintaining the lower fuel consumption of a small displacement port-injected engine. Producing 260 SAE horsepower (~194 kW) and 260 lb.-ft. (~350 Nm) of torque, the engine is GM’s highest specific output production engine ever and is the most powerful production engine in the ECOTEC family. The engine is GM’s first direct injection offering in North America. The engine was developed with the global resources of GM Powertrain in the United States and Europe, drawing on expertise from the naturally aspirated ECOTEC directinjection and dual continuously variable cam-phased engines and turbocharged engines already in production.
