This versatile engine serves as both a high-efficiency standard engine in the Silverado and a high-performance upgrade in the Colorado.
The 2.7L L3B TurboMax is the standard engine on many popular Silverado trims (WT, Custom, Custom Trail Boss, LT, RST, and LT Trail Boss), offering more standard torque than many V8 options. It provides an impressive mix of capability and fuel economy for everyday work and driving.
In the Colorado lineup, the L3B is the high-output upgrade. It's available as an option on the Z71 and Trail Boss trims and is the standard engine for the top-tier, off-road-ready ZR2, delivering maximum power for any adventure.
The defining feature of the TurboMax engine is its 430 lb-ft of torque. This immense pulling power is available low in the RPM range, giving both the Silverado and Colorado a strong, confident feel from a stop and when towing.
This engine proves that a smart, turbocharged 4-cylinder can easily do the work of a much larger, less efficient V8.
