GM DRIVETRAINS
The Ecotec 2.0L SC (Supercharged) is compact and lightweight, and its Eaton M62 Supercharger adds 40
percent more power to the Ecotec 2.0L engine compared to a naturally aspirated version. The M62
supercharger utilizes a helical roots compressor and integral pressure control, producing a maximum of 12-19
PSI of boost. The boosted intake flow exits into an all-new matched intake manifold with an integral air-to-
liquid heat exchange intake charge cooler system. A compact single-track, six-rib belt supercharger drive
system utilizes a linear tensioning device to further strengthen the already impressive system performance and
durability. A microprocessor manages the M62 supercharger, fuel, direct spark delivery systems and the
engine’s 68-mm Electronic Throttle Control (ETC) system. ETC delivers outstanding throttle response,
improved reliability and better integration with cruise control electronics for greater overall performance and
drivability.
The Ecotec 2.0L SC engine is built with a six-quart oil sump and a crankshaft driven pump. A block-mounted
oil cooler, or optional remote cooler, is included to ensure proper lubricant cooling that promotes long engine
life.
The 2.0L SC engine is built exclusively at the FGP (Fiat-GM Powertrain) engine facility in Kaiserslautern,
Germany. This plant uses a die-cast production technique that yields a block that is well suited for high-stress
applications including turbocharging and supercharging.
Often referred to as the Global Four Cylinder, the starting point for the 2.0L SC is the Ecotec 2.2L (RPO L61).
This engine has leveraged GM Powertrain’s worldwide design and engineering capability by drawing on the
best practice of technical centers in North America and Europe. The Ecotec 2.2L created a template for
subsequent global powertrain development that laid the groundwork for engines such as Powertrain’s new
Global 3.6: V6. Most important, the Ecotec 2.2L is a world-class gasoline engine with obvious benefits for the
