General Motors and Chevrolet Motor vehicles use Vortec series engines. The Vortec series is a trademarked name of piston engines that were initially created for GM trucks but eventually branched into the Chevrolet company.
There are four classes of Vortec engines that range from four-cylinders to eight-cylinder variants. The name Vortec was first used publicly in 1984, in an advertisement showcasing the technology that created a vortex inside the combustion chamber. The vortex was then able to create better fuel economy for the engine. As of February 2015, there is currently one Vortec engine still being produced: the L96 engine. Besides the L96 engine, the Vortec series was replaced by the Ecotec variant.
The L96 is a 6.0 liter V8 Vortec engine that produces 360 horsepower and 380 foot pounds of torque. It manages to use an efficient intake system that produces nice flow throughout the engine. The engines feature advanced electronic throttle control, quiet exhaust manifolds, camshaft phasing and flex-fuel capability. Another feature is the 58X ignition system. The 58X ignition system allows the engine to retain correct timing throughout its operation. This precision allows the engine to maintain optimal fuel economy throughout its operating range.
The following vehicles use the L96 as their engine:
- Chevrolet Express
- Chevrolet Silverado
- Chevrolet Suburban 2500
- GMC Savannah
- GMC Sierra HD
- GMC Yukon XL
