GMC has always developed durable, bulk, rugged and high-performance pickup trucks and the all-new Sierra HD is announced with increase performance and much more advanced mechanics.
From a visual standpoint, the 2017 GMC Sierra HD is looking fabulous with the company`s signature surrounding the body, while the powertrain is the car`s main highlight. The most important features that refer to the new styling add-ons refer to the custom air intake system, as well as the more prominent hood scoop.
But to achieve such impressive power, the company had to make some serious adjustments, fitting the pickup truck with a lot of up-to-date mechanics.
We are looking here are at a new cylinder block and cylinder heads, increased oil and coolant-flow capacity, new electronically-controlled turbocharger, B20 bio-diesel compatibility, custom rocker cover, updated solenoid duel system, new camshaft and so on.
All these contribute to the pickup`s impressive power, meaning that the 6.6-liter turbo-diesel Duramax V8 engine is now capable of delivering 445 horsepower and 910 lb-ft of torque, which means a 19 percent torque more than the present V8 power. This means that 90 percent of the engine`s power is available between 1,550 rpm and 2,850 rpm, which is the perfect timing for the most difficult towing.
The pricing details or the performance figures are not yet revealed, but we should expect fresh details in the upcoming period.
