The 2019 Chevrolet Silverado and GMC Sierra will be
offered with a new 3.0-liter Duramax turbodiesel six-cylinder engine. GM hasn’t
said much about the engine, but it specifications might have just been leaked.
TFLtruck says a reader sent in pictures of GM
Canada’s dealer website where the engine’s performance specifications were
listed. They show the diesel will produce 282 hp and 609 Nm of torque. If those numbers are accurate, the Duramax would outgun the 3.0-liter
Power Stroke diesel engine that is available in the Ford F-150. It produces 250
hp and 595 Nm of torque.
The 2019 GMC Sierra
diesel will be able to return 28 mpg highway. The document doesn’t indicate
which particular version of the truck is capable of returning that figure, but
the most fuel-efficient version listed by the EPA – a rear-wheel drive model
with the 5.3-liter V8 engine – returns 23 mpg highway.
If that 28 mpg number is correct, the diesel-powered
Sierra will likely offer similar fuel economy ratings to the F-150. Of course,
there are countless versions of the truck and the F-150 diesel has an EPA
rating that ranges from 20 mpg city / 25 mpg highway / 22 mpg combined to 22
mpg city / 30 mpg highway / 25 mpg combined.
In terms of towing, the Sierra diesel will reportedly
be able to pull up to 3,538 kg. This is one area where the F-150
diesel has a clear advantage as Ford has previously confirmed the truck has a
towing capacity of up to 5,170 kg. That’s a pretty sizable
difference of 1,632 kg.
