GM 6.0L Vortec L96 V-8

6.0L Vortec V-8 Specifications and Information

General Motor's 6.0L V-8, or Vortec 6000, has been the gas engine of choice in the company's heavy duty applications, including the Chevrolet Silverado and GMC Sierra 2500/3500, since the 2010 model year. While the engine produces much less power than the Sierra/Silverado 1500's high compression 6.2L V-8, the 6.0L is better suited for heavy truck applications as a result of its mild compression ratio and broad, flat torque curve. It's lower horsepower and torque ratings also reduce fuel consumption and improve reliability.

At the 364 cubic inches of displacement, the engine is rated at a respectable 360 peak horsepower and 380 lb-ft peak torque. More importantly, the engine features a relatively broad, flat torque curve and a linear horsepower curve that grows sharply. In addition to Chevrolet Silverado and GMC Sierra 2500/3500 pickup trucks, the 6.0L is and/or has been offered in the Suburban 2500, Yukon XL, Express, Savana, and all chassis cab trucks. All 6.0L Vortec engines are mated to GM's 6L90 automatic transmission.

The 6.0L Vortec features unique high flow cylinder heads with "cathedral" shaped intake ports and "D" shaped exhaust ports. Its sister engine is the 6.0L LC8, which features the same basic engine structure but has been engineered to run on compressed natural gas (CNG).

2010 - 2018 6.0L Vortec L96 Horsepower and Torque Curves

Though the 6.0L Vortec may be comparatively lacking in overall horsepower and torque, it exhibits a relatively flat torque curve (although peak torque is produced unfavorably high in the powerband) and a steady, sharp climbing horsepower curve. Torque remains reasonable as the engine approaches its 6,000 RPM redline.

The 6.0L Vortec gasoline engine has been offered beside the 6.6L Duramax diesel since the 2010 model year. While the Duramax displays far superior performance characteristics, the 6.0L Vortec is an economical choice for buyers who require a truck with a high GVWR but aren't able to justify the additional cost of the diesel platform and/or will not utilize the diesel to its full potential. After all, the cost of ownership can prove considerably higher with modern, emissions controlled diesel engines. For heavy towing needs, there remains no alternative to the Duramax's high torque rating and favorable fuel economy under rigorous conditions.
