The Genesis G80 3.8-liter direct-injected Lambda engine is optimized to deliver a flatter overall torque curve at low rpm for superb drivability.This engine includes a three-stage variable intake system,triangular-pattern fuel injector for improved combustion,
an air-gap exhaust manifold for better NVH, and an upgraded cylinder block with a variable-vane 2-stage oil pump for reduced parasitic losses. In keeping with its 5.0-liter V8 sibling, the G80 3.8-liter Lambda engine utilizes direct-injection and produces 311 horsepower at 6,000 rpm and 293 lb.-ft. of torque at 5,000 rpm, delivering the most standard horsepower against key segment competitors. It also has a high compression ratio of 11.5:1 for greater thermal efficiency. The Lambda engine will run on regular fuel with only a small reduction in peak power, and no negative driving effects.
