Meet the small-but-mighty L3B 2.7L Turbo 4-cylinder, an engine built from a clean-sheet design specifically for light-duty pickups. For the 2022 model year of Chevrolet and GMC 1500 pickups, General Motors re-engineered this workhorse for a quieter experience, while also re-tuning it to deliver 20% more torque than its predecessor from 2019.
 
The result?
A smaller engine that not only saves you fuel, but touts a surprisingly capable 430 lb.-ft. of torque and a maximum 4WD Crew Cab conventional towing capacity of up to 9,000 lbs¹.
 
Paired to a smooth-shifting 8-speed automatic transmission, the 2.7L Turbo is standard in:

• Silverado 1500 Work Truck, Custom, Custom Trail Boss, LT, and LT Trail Boss
• Sierra 1500 Pro and Elevation

GREAT POWER, MORE RESPONSIVE
Up against GM's sturdy 5.3L V8, the 2.7L I4 holds its own:
 

	L84 5.3L V8	L3B 2.7L I4
Cylinders	8	4
Horsepower	353	310
Torque (lb-ft)	383	430
Acceleration (sec) 0 to 100 km/h	6.5	6.2
4WD Fuel Consumption (L/100km Energuide)	13.4 Combined	13.1 Combined

 

TOUGH ON TOWING
The 2.7L Turbo isn't left in the dust when you compare towing numbers, either:
 

	L84 5.3L V8	L3B 2.7L I4	L87 6.2L V8	LM2 3.0L I6 Duramax
Max Towing (non-NHT2) 4WD Crew Cab Short Bed	9,200 lbs	9,000 lbs	9,100 lbs	9,000 lbs

 

The 2.7L Turbo High-Output makes good use of power dense fuel-saving technologies including:

• Variable Valve Timing
• Direct Injection
• A Dual-Volute Turbocharger
• 3-phase Sliding Camshaft
• Active Fuel Management

 

DUAL-VOLUTE TURBOCHARGER
Delivers a noticeably quicker engine response time when accelerating from low speed. The Dual-Volute geometry allows for the complete separation of engine exhaust gases so more exhaust energy is available to the turbine wheel. By splitting the exhaust gases it’s like having two turbos providing more boost for superior performance.
 
3-PHASE CAMSHAFT
Provides three levels of valve lift resulting essentially in three levels of power:

• High Lift is the default mode, providing more power on demand for initial accelerations or for passing.
• Low Lift provides a balance between power and fuel efficiency for times when full power isn’t required.
• And finally, there’s the “No Lift” mode or “Active Fuel Management,” which deactivates two out of the four cylinders in light load conditions providing even more fuel efficiency.
