The Isuzu N-Series gas truck is powered by General Motors' 6.0L Gen IV small block V-8 engine, coupled to a new double overdrive 6-speed automatic transmission with lockup torque converter that improves both vehicle performance and fuel economy.
With 297 hp and 372 ft.-lbs. of torque, the engine carries on with well-proven design features like a 100,000 mile maintenance-free ignition system, a long-life timing chain and cast stainless steel exhaust manifolds. The Isuzu N-Series gas truck is also available with an optional CNG/LPG capable engine.
