Diesel Duramax engines in the newest GMC Trucks in Ontario has the industry buzzing. Here, we wish to wrap up our segment on these new Truck engines and make sure to finish pointing out all that is great about them here. “The new Duramax 6.6L is a next-generation redesign of the venerable turbo-diesel engine and incorporates a new, GM-developed control system. The Duramax’s signature low-rpm torque production hasn’t changed, offering 90 percent of peak torque at a low 1,550 rpm and sustaining it through 2,850 rpm — an attribute that contributes to the Sierra HD’s confident pulling power.”
So, obviously power in the push and pull are both being added to these trucks as a result of these new engines. The GMC Trucks for sale at your Thunder Bay GMC Truck dealer with these new engines also have something else new this year, patent is pending, but the air intake system which you can identify on the GMC Sierra HD by its bold scoop in the hood, will drive cool and dry air into the engine, helping to sustain these trucks performance and allow for cooler engine air temperatures at almost all times.
The cooler air, mentioned above, that results from this new intake construction, is essential in engine health and function. “Cooler air helps the engine run better under load, 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.” So, the gain here, when it comes to these Thunder Bay Truck engines in Canada, is definitely in engine ability, but what many don’t understand is that with any new abilities, other things often times must be considered and constructed to maintain the balance of the engine. The above air intake and discussion of engine temperature is a prime example of this concept at work.
