With 4 cylinders, 16 valves and 200 horsepower, the powerful 2.8-liter new Duramax diesel engine delivers 500 Nm of torque at 2,000 rpm. This high-performance, fuel-efficient engine employs a direct injection system, a variable geometry turbo, and an intercooler to boost torque at low revolutions. A lightweight servomotor controlled by the Engine Control Module (ECM) dramatically improves driving performance. Power is delivered with great consistency, and optimal fuel efficiency is obtained with an overdrive gear of two gear ratios. The engine is teamed with a 6 speed active select automatic transmission, and precise gear changes make driving more enjoyable.
With 4 cylinders, 16 valves and 163 horsepower, the robust 2.5-liter new Duramax diesel engine delivers 380 Nm of torque at 2,000 rpm. Despite the engine’s impressive output, it’s also remarkably fuel-efficient, thanks to its direct injection system. The turbocharger and intercooler system work together to regulate the temperature and density of the air being circulated in the engine at any given time to improve combustion and optimize horsepower and torque. The engine is matched to a smooth-shifting, 6-speed manual transmission that makes changing gears quick and effortless.
