This just in: OFFICIAL price and specs for GM’s 3.0-liter Duramax diesel engine.
The new 3.0-liter Duramax in both the Chevy Silverado and GMC Sierra will produce 277 horsepower at 3750 rpm and 460 lb-ft of torque at 1500 rpm. The power will be sent through a 10-speed automatic transmission.
This means that the GM 3.0-liter is the most powerful diesel in a half-ton on the market. The Ford F-150 uses a 3.0-liter diesel as well producing 250 hp and 440 lb-ft of torque, though its a V6 rather than inline cylinders.
The 2019 Ram 1500 still isn’t available with the updated EcoDiesel, though when it is made available again, it will likely produce the same 260 horsepower and 442 lb-ft of torque that was announced for the engine by the Jeep brand.
Orders for the new Duramax diesel in the Silverado and Sierra will be taken soon and GM says that the first customer deliveries will begin this summer.
