New 445 Horsepower Heavy-Duty Duramax Engine From GM

GMC’s heavy-duty trucks, fitted with the Duramax engine, deliver superior capability and power. The GMC Duramax engine can be counted on to get the job done, and is increasingly looked to by working professionals. GMC’s Duramax engine has forged a bond with customers based on capability and trust. GMC has sold nearly 2 million vehicles powered by the Duramax engine, over the past 15 years.

GMC has now taken the Duramax engine to new heights with the release of the new 6.6L L5P Duramax turbo-diesel V-8 engine destined for GMC’s 2017 model year heavy-duty pickup trucks; including the new 2017 GMC Sierra HD. The redesigned Duramax engine offers more torque and horsepower than ever before, enabling easier trailering and hauling. 

The new 6.6L L5P Duramax turbo-diesel V-8 engine will pump out 445 horses and 910 pound-feet of torque! That’s a 19% increase in max torque over the outgoing Duramax 6.6L! Along with greater torque and more horsepower, the redesigned turbo-diesel Duramax engine is also much quieter. In fact, engine noise, at idle, is reduced 38%. 

The impressive power of the new Duramax engine wouldn’t be possible without the proper amount of air intake. The engineers at GMC have created a new, patent-pending vehicle air intake system that drives cool, dry air into the engine for sustained performance. Cooler air helps the engine run better, especially in conditions where engine and transmission temperatures can rise quickly. That allows the Duramax to maintain more power and vehicle speed when trailering in the toughest conditions. 

The new intake design is distinguished on the 2017 GMC Sierra HD, by a bold hood scoop, and is another example of the advanced integration included in the 2017 Sierra HD that makes it over-the-road capable.

The new Duramax 6.6L is matched with the Allison 1000 six-speed automatic transmission. The transmission has undergone several refinements to accommodate for the new engine’s higher torque capacity, including a new torque converter. The Allison 1000’s Tow/Haul mode reduces shift cycling for improved cooling and better control when towing or hauling heavy loads. 

A new, smart diesel exhaust-brake feature enhances control when descending steep grades. The integrated exhaust-brake system makes trailering less stressful by creating additional backpressure in the exhaust, resulting in negative torque during deceleration and downhill driving, enhancing driver control and prolonging brake pad life. A new electronically controlled, variable-vane turbocharger helps the engine make more power, and revisions to enhance the capability of the exhaust-brake system.

GMC Canyon Diesel: Coming soon to the Tulsa Metro!

Well, it's official folks! Our new truck shoppers will soon be able to purchase the 2016 Canyon fitted with a diesel engine! There had been rumors swirling since the release of the all-new GMC Canyon, back in 2015. Now we know, a diesel mid-sized truck from GMC will soon be a reality, and it was on the books from the start. 

“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. 

The 2016 GMC Canyon diesel will be fitted with a the new 2.8L Duramax diesel engine. The new Duramax diesel takes the GMC Canyon's award-winning capabilities to a new level in the mid-sized truck segment. The engine gives the GMC Canyon a powerful advantage over the competition with 181 horsepower and 369 lb-ft of torque. The 2016 GMC Canyon diesel will be able to tow up to 7,700 pounds thanks to an all-new powertrain - expanding the trucks class-leading capabilities even more. 

Several new technologies and supporting features complement the Duramax diesel’s capability while helping ensure GMC’s trademark refinement: 

• A new, electronically controlled two-speed transfer case on 4WD models  
• An all-new integrated trailer brake controller is standard and exclusive on diesel models  
• Smart diesel exhaust brake system that enhances vehicle control and reduces brake wear on steep grades  
• Standard Hydra-Matic 6L50 six-speed automatic transmission matched with a Centrifugal Pendulum Vibration Absorber in the torque converter, which reduces powertrain noise and vibration 

In addition, the 2016 Canyon offers technologies and connectivity features such as GMC IntelliLink with new phone integration technology – and Apple CarPlay capability – OnStar 4G LTE with Wi-Fi hotspot, Forward Collision Alert and Lane Departure Warning. 

Additional engine features: 

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

Of course with Volkswagen’s diesel engine Environmental Protection Agency emission test cheating fallout, the new 2016 GMC Canyon diesel will have to be put through a new, more rigorous test from the EPA, but we're confident the mid-sized pickup will pass the test with flying colors; and so is GMC stating, "The Duramax 2.8L 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 new 2016 GMC Canyon diesel will offer our Oklahoma truck enthusiasts exceptional capability delivered with a confident feeling of control. It's expected to arrive at our Tulsa Metro, Buick GMC dealership later this year.
