Ever since GM
announced that the all-new Chevy Silverado and GMC Sierra would get an inline
six-cylinder diesel, prospective customers wondered how much power and torque that engine would make. Well, they need not wonder anymore
because the new Duramax engine’s specs have been uncovered. The 3.0-liter
straight six will deliver 277 hp at 3,750 rpm and 623 Nm of torque at just 1,500 rpm. The only transmission choice will be a 10-speed
automatic.
The specs have been
found on the GMC build and price tool and confirmed by a GM representative to
TFLTruck. So there you have it, the 2019 Chevrolet Silverado 1500 and 2019 GMC
Sierra 1500 will offer the most powerful diesel engine in the segment. As a
reminder, the 2018 Ford F-150’s Power Stroke V6 produces 250 hp and 596 Nm of torque. As for the Ram 1500, the new generation model hasn’t
received the updated 3.0-liter EcoDiesel V6 yet. However, when it becomes
available the updated diesel unit will likely deliver the same power and torque
as in the Jeep Gladiator: 260 hp and 600 Nm.
While the Silverado
and Sierra Duramax will offer the most powerful diesel engine of all half-ton
pickups, it remains to be seen whether they will also be the most economical.
The Ford F-150 Power Stroke, for example, offers an EPA-estimated fuel economy
of 30 mpg highway, 22 mpg city, and 25 mpg combined.
On the Silverado,
the Duramax engine will be available on LT, RST, LTZ and High Country trims. In
the Sierra, the new diesel engine will be available on all trims except the
base model. GM will soon start taking orders for the new Duramax diesel in the
Silverado and Sierra, with the first customer deliveries to begin this summer.
