GMC was awesome enough to invite us into the heart of the Rocky Mountains in Telluride, Colorado – a place where there’s only one road in and out – to drive the 2017 GMC Sierra 2500 HD and 3500 HD pickups. We expect to get a real-world feel of what the reworked 6.6L Duramax V8 diesel engine is capable of with its 445 horsepower and 910 lb-ft of torque. It’s otherwise a rather familiar pickup truck, but that doesn’t mean some of you have questions we could ask engineers and other subject matter experts on-hand at your behalf.
At this point, we’d like to remind that, yes, there is such a thing as a dumb question. With that said, ask away!
