5.3L Small Block V8 Engine

---

The small block V8 in SS models features:

• Active Fuel Management™ for an EPA estimated 16 city, 24 highway MPG.
• Aluminum Construction — all major castings in the V8 engine, including
• the deep-skirt engine block, are made of weight-saving aluminum. Casting from aluminum contributes to a stiff engine structure that helps ensure smooth operation
• Electronic Throttle Control (ETC) — ETC replaces the mechanical link between the accelerator pedal and engine with drive-by-wire electronic control. This allows for remarkably smooth and precise acceleration
• Polymer-Coated Pistons — pistons are coated with a polymer material that reduces engine wear and contributes to quieter operation
• Cylinder-Head Technology — the small block V8 cylinder heads were originally developed for the Corvette Z06. Their pent-roof combustion chambers and flat-top pistons deliver high horsepower
• Composite Intake Manifold — the composite intake manifold design allows the small block V8 to deliver high levels of torque at low and mid-range engine speeds while still delivering plenty of airflow for peak engine horsepower
