At the end of September, some of my auto journo colleagues busied themselves with the French delights of Paris, covering new reveals at the Paris Auto Show.

Me? I was somewhere much more in line with my personality, surrounded by heavy-duty trucks at the 1.5-mile Texas Motor Speedway. With both Ford and Ram cresting the 900 lb-ft of torque mark, the General needed to play catch-up.

Enter Chevy’s new 6.6-liter Duramax Diesel.

A document containing official horsepower and torque numbers for General Motors’ new 6.6-liter V8 Duramax turbo-diesel was found buried on the GM Powertrain website — before the company quickly deleted it.

You remember the hood scoop on that teased 2017 GMC Sierra 2500HD? The one General Motors really wanted you to notice?

Well, GM spilled the beans on the mystery inlet, explaining that all of its diesel-powered 2017 heavy-duty pickups will receive the scoop to force-feed air into the 6.6-liter Duramax engine.
