Performance from GM’s ECOTEC family of engines continues to advance with the 2.0L Turbo LTG, based on a generation of large-displacement four-cylinder engines that are designed for greater efficiency.

The turbocharger’s twin-scroll design helps optimize the usable power from the engine, virtually eliminating turbo lag and helping deliver a broad power band. It also gives the engine the rapid throttle responsiveness associated with a higher-displacement, naturally aspirated high-performance engine. Electronically controlled supporting components, including the wastegate and bypass, help optimize performance and efficiency.
