customer. At 307 pounds fully dressed, the L61 is the lightest engine GM has produced in its displacement
class, and one of the most compact four-cylinders in the w orld.

Before going into production, every Ecotec engine va riant is subjected to the toughest and most
comprehensive validation process ever carried out at GM, having to pass all of the dynamometer and vehicle
tests traditionally run by various GM organizations wo rldwide, including the most severe trials. Coinciding with
the rollout of the Ecotec program, general engine dur ability testing on lab dynamometers was increased by 60
percent. This has been carried forward to the new Ecot ec supercharged engine.
