In addition to two gasoline powerplants, the GMC Canyon lineup offers a unique option: the 2.8-liter Duramax turbo-diesel four-cylinder, a precision-engineered engine that expands the Canyon’s already formidable capabilities, including trailering capacity of up to 7,700 pounds (3,492 kg).

The 2.8-liter Duramax diesel, SAE-certified at 181 horsepower and 369 lb-ft of torque, also delivers on efficiency. Two-wheel drive models equipped with the engine are EPA-rated at 30 mpg highway.

“A diesel engine was part of the Canyon’s portfolio plan from the beginning, meaning the chassis, suspension and other elements of its architecture were engineered to support it,” said Scott Yackley, assistant chief engineer. “That means there are no compromises with the Canyon diesel. It offers exceptional capability delivered with a confident feeling of control.”

Designed For Durability
The Canyon small pickup truck’s new 2.8-liter Duramax turbo-diesel is part of General Motors’ global family of turbo-diesel four-cylinder engines designed to deliver capability and efficiency. It features a variable-geometry turbocharger for optimal power and efficiency across the rpm band and a balance shaft for greater smoothness.

"The new 2.8-liter Duramax was designed specifically for trucks and has undergone many of the same validation tests as the 6.6-liter Duramax offered in the GMC Sierra HD models, advancing the Duramax brand’s legacy of durability and reliability,” said Yackley.

The Duramax 2.8-liter is the cleanest diesel truck engine ever produced by GM and meets some of the toughest U.S. emissions standards, thanks in part to a cooled exhaust gas recirculation (EGR) system.

The cooled EGR system lowers combustion temperatures and rates, improving emissions performance by reducing the formation of nitrous oxide (NOx) emissions.

Smart exhaust brake details
The Canyon’s integrated, driver-selectable exhaust brake system is based on the system introduced on the Sierra HD models and uses the compression power of the 2.8-liter Duramax engine to improve vehicle control and reduce brake pad wear.

When the exhaust brake is engaged in cruise mode, exhaust cruise grade braking helps the cruise control system maintain the desired downhill vehicle speed, keeping the driver from having to apply the brakes and exit cruise control to maintain speed.

When the exhaust brake is engaged in non-cruise mode, the transmission and the exhaust brake deliver the correct amount of braking to assist in vehicle control, regardless of vehicle load. It is a smart system that varies the amount of braking needed for the vehicle, load and grade. The engagement of the system is smooth and quiet, while its performance enhances the driver’s feeling of control.

CPVA contributes to refinement
The Centrifugal Pendulum Vibration Absorber (CPVA) in the torque converter is designed to control vibration and noise. It is an absorbing damper with a set of secondary spring masses, that — when energized — helps to cancel out the engine’s torsional vibrations so the driver and passengers can’t feel them. Its use in the Canyon marks the first application of a CPVA in GM vehicles and its first use in the midsize truck segment.

Additional engine features include:

  • Iron cylinder block and aluminum DOHC cylinder head
  • Forged steel crankshaft and connecting rods
  • Oiling circuit that includes a dedicated feed for the turbocharger to provide increased pressure at the turbo and faster oil delivery
  • Piston-cooling oil jets
  • 16.5:1 compression ratio
  • Common rail direct injection fuel system
  • Ceramic glow plugs for shorter heat-up times and higher glow temperatures
  • Balance shaft that contributes to smoothness and drives the oil pump
  • Laminated steel oil pan with upper aluminum section that contributes to engine rigidity and quietness
  • B20 bio-diesel capability
