The turbocharged Ecotec 1.4L is part of GM's small-displacement, power-dense four-cylinder engines. The wide rpm range for maximum torque helps the engine deliver better driving experience and performance. This turbocharged engine's power-boosting advantage comes from forcing greater airflow into the engine. Its pressurized charge packs more air into the cylinders, allowing them to process the air and fuel of a larger engine for momentary driving situations.
The 1.4L's turbocharger is integrated within the exhaust manifold, for reduced weight and greater packaging flexibility in smaller vehicles. The engine incorporates numerous mass-reducing features, including a cast iron block with a hollow frame structure, hollow-cast camshafts and a plastic intake manifold.
