The engine also includes a variable valve timing system, allowing for optimal engine performance across the entire RPM range.

Additionally, this engine meets stringent emissions regulations, including the US EPA's Tier 3 Bin 5 and EURO 6 standards. It achieves this by incorporating technologies like a cooled exhaust gas recirculation system, a close-coupled catalytic converter, and a secondary air injection system.

The 1.4L 8th Generation Opticam LE2 Cruze Engine is a versatile powertrain solution, capable of producing around 153 horsepower at 5,600 RPM and 177 lb-ft of torque at 1,850-4,900 RPM. This engine offers impressive fuel economy, with an estimated combined rating of up to 31 miles per gallon (US).
