GMC News: Rumorpile: Details of 3.0L Duramax Turbodiesel for GMC Sierra Leak Out

[William Maley]

Aside from the turbo-four engine, the 3.0L Duramax diesel inline-six for the upcoming 2019 Chevrolet Silverado and GMC Sierra 1500 has us very intrigued. General Motors has been quiet on power figures and fuel economy for this engine since announcing this engine earlier in the year. But thanks to a crafty person who got some photographs off of GM Canada’s dealer site, we now have some figures.

The photos were posted by TFL Truck and reveal the diesel engine produces 282 horsepower and 450 pound-feet of torque - 32 horsepower and 10 pound-feet more than the F-150's 3.0L PowerStroke diesel. GM also claims a highway fuel economy figure of 28 mpg - about two mpg less than the F-150. That 28 mpg figure gives us pause as Canada reports fuel economy figures very different - 'x' liters per 100 kilometers - not miles per gallon.

Max towing is rated at 7,800 pounds.

We'll see if those numbers pan out when the diesel becomes available sometime later this or early next year.

Wonder if it will sell though?

Numbers-wise, it doesn't pay to buy the diesel to save fuel money.
I did some figuring on the Ram V6 gas vs. I6 diesel a few years ago and it was going to take something like 19 years to break even.
Just watched a vid on the F-150 diesel and it was of the same opinion- fuel cost savings were between $46 - 200/year, but the 3.0 PowerStroke costs in the $4K range- at $200 yr savings on fuel, that's again 20 years to break even.

Buy a diesel because you like the power, or the longevity, or merely the image... but not for fuel savings.
