Built for performance and durability, the all-new 6.6L V8 delivers 481 hp and 501 lb.-ft. of torque. It’s strength right where you need it.
At the core of GM’s 6.6L V8 is an aluminum block with cast iron cylinder liners and 6-bolt main bearing caps. Topped with aluminum heads, it makes a lightweight, strong framework, the same blueprint that has anchored V8 engines for decades. A new throttle body, new dual fuel injection system, modified compression ratio and increased displacement make it highly capable and built to last.
Airflow is crucial to power. A new, larger throttle body and tuned intake runners work together to deliver air to the combustion chamber, helping maximize horsepower, torque and efficiency. Advanced cam phasing precisely controls valve timing to help ensure optimal airflow.
The reimagined 6.6L V8 uses both Direct Fuel Injection and Port Fuel Injection. This tandem design balances horsepower and efficiency, with favorable emissions and reduced fuel system noise at warm idle.
An increased compression ratio, longer piston stroke and 400 cu. in. of displacement provide impressive power and efficiency. A specialized piston bowl design, cam profiles and the new dual fuel injection system complete a workhorse engine that can tackle inclines, tow trailers and haul hefty loads.
Lubrication is a vital contributor to an engine’s durability. This new system features a larger dual main bearing oil feed design that supplies consistent pressure and volume. Paired with a continuously variable oil pump, it delivers oil pressure as required, while the block-mounted oil cooler helps keep the engine at its optimal temperature.
