The light-duty Chevrolet Silverado 1500 is offered with a wide variety of powerplant options to satisfy customers, including the turbocharged 2.7L I4 L3B gas unit. Making its debut on the 2019 Chevrolet Silverado 1500 and 2019 GMC Sierra 1500, the L3B is a modern, power-rich four-cylinder that delivers not only efficiency, but surprising performance as well. In fact, the Silverado turbo 2.7L I4 will sprint to 60 mph a full second quicker than the 4.3L V6.
As GM Authority covered previously, it was already known that a gas-powered Silverado turbo would hit 60 mph in under 7 seconds. Now, however, GM Authority has uncovered the more specific 0-to-60 mph acceleration figure of 6.8 seconds, which means the boosted four-banger can complete the test a full second quicker than the same truck with the base naturally aspirated 4.3L V6 LV3 gas engine.
Offered as standard on LT and RST trim levels, the turbocharged 2.7L I4 L3B gas engine produces an SAE-certified 310 horsepower and 348 pound-feet of torque, with peak twist coming online between 1,500 and 4,000 rpm.
Highlight features include an innovative double overhead cam valvetrain, as well as Active Fuel Management (i.e., cylinder deactivation) and continuously variable valve timing. The turbo comes with a dual-volute housing that sharpens throttle response and boosts low-speed torque figures, and the engine represents Chevy’s first application of Active Thermal Management technology.
“The new 2.7L Turbo engine represents a clean-sheet design for Chevrolet and was developed from the outset as a truck engine,” Chevy explains.
In order to help it make plenty of low-end torque, the turbocharged four-cylinder was designed with a long piston stroke of 4.01 inches (102 mm), improving combustion and enabling a higher compression ratio.
“Typically, a long stroke can increase the load of the pistons against the cylinder walls, generating more friction,” Chevrolet explains. “That’s alleviated in the 2.7L Turbo with an offset crankshaft. It is slightly off-center of the cylinders, allowing a more upright position for the connecting rods during their movement.”
Combining efficiency, clever technology, and plenty of power, the 2.7L I4 L3B gas engine in the Silverado turbo has a lot to offer customers – including extra scoot to 60 mph.
