With rival 3/4-ton and full-ton pickups encroaching on 1,000 lb-ft of torque straight from the factory, the current GMC Sierra HD’s 765 lb-ft is beginning to seem paltry. Never mind that it has constantly excelled in real world testing versus the likes of Ford and Ram, because sometimes it is just a numbers game. And sometimes the players have to come up with bigger numbers.
Enter the 2017 GMC Sierra HD. Seen here in Denali form, its fully functional hood scoop hints at a titanic powerplant that is sure to build on the current 397 hp and 765 lb-ft currently offered. Likely from cooling improvements to the existing 6.6L Duramax V8 diesel engine. With that said, GMC is currently keeping all information under lock and key — we have no leads as to what the power figures will be, or if it’s even the same Duramax engine, let alone an all-new one. Only the picture of this 2017 GMC Sierra 2500HD Denali was released. Big Red isn’t about to show its hand in this ever-ongoing poker game just yet. So that leaves us with nothing but our wandering imaginations to think of what’s hiding behind that massive mail slot of a hood scoop. And our imaginations are downright reckless.
