277 horsepower and 460 pound-feet of torque.
Statement from GM:
"The all-new, Duramax 3.0L inline-six turbo diesel will deliver an SAE-certified 277 hp and 460 lb-ft of torque, more than any other light-duty, full-size truck diesel available. Dealers and customers can place orders for the efficient, refined diesel and the first customer deliveries begin this summer. We will share more information, including towing capacity and efficiency, in the near future.
It is priced identically to the 6.2L V-8 as a $2,495 premium over a 5.3L V-8 model (or $3,890 over a 2.7L Turbo model) making the 3.0L Duramax the most affordable light-duty diesel engine on the market.
The 3.0L Duramax turbo-diesel is available on the Chevrolet Silverado LT, RST, LTZ and High Country trims, as well as all GMC Sierra trims except the base Sierra trim."
