The GM L3B is a turbocharged four-cylinder gasoline engine that General Motors designed for its full-size pickup trucks. It is an undersquare aluminum inline-four with double overhead camshafts, displacing 2.7 liters, and it is tuned for strong low-end torque. It combines active fuel management, which can shut down the middle two cylinders under low power, with start-stop, variable valve timing and an intake valve lift control that has three electromagnetically actuated cam profiles. A BorgWarner dual-volute turbocharger with an electrically actuated wastegate can reach up to 27 psi of boost. The L3B was first used in the Chevrolet Silverado and GMC Sierra, its parts are cast at Bedford in Indiana and it is assembled at Spring Hill in Tennessee, and it succeeded the 3.6 liter LGX and LGZ and the 4.3 liter LV3 V6 engines.
