How to Identify a DOD Engine

DOD (Displacement On Demand) or AFM (Active Fuel Management) allows your V8 engine to save fuel by running as a 4 cylinder engine under steady, light load conditions.



How to Identify a VVT Engine

VVT (Variable Valve Timing) allows your engine to develop more torque or horsepower under various conditions by advancing or retarding the camshaft.
