GM releases many more details about the upcoming Chevy Silverado 1500 3.0L Duramax I6 turbo diesel. We take a look inside the engine to see what makes it tick. It’s a very high-tech and state of the art diesel, but will people buy it in great numbers?

We now know most of the specs about this new engine with exception of perhaps the most important piece of information – the engine’s fuel economy estimates.

Before we dig deep into the engine, let’s recap what we already know. The light duty turbo diesel is rated at a class-leading 277 horsepower and 460 lb-ft of torque. GM says 95% of maximum torque arrives at 1,250 rpm. The maximum 460 lb-ft is available between 1,500 – 3,000 rpm. The engine is mated to a 10-speed automatic transmission as the only choice.

The diesel will be available in Chevy Silverado 1500 and GMC Sierra 1500 trucks at the same price as the 6.2-liter V8 / 10-speed powertrain combination. In the Silverado, in means the diesel costs $2,495 over a 5.3-liter V8 or $3,890 over a 2.7-liter gas turbo-four.

In the Chevy, the engine will be available in LT, RST, LTZ, and High Country trim levels. The 3.0-liter Duramax-powered trucks are rated at 9,700 lbs of maximum towing in 2WD or 9,400 lbs towing in 4×4 configuration.

Now, we learn that the engine has an aluminum block and cylinder head. It is a Dual Overhead Cam (DOHC) design with four valves per cylinder. It’s equipped with an exhaust brake to help it slow down heavy loads.

The engine is equipped with active thermal management system for quick warm-ups or improved cooling. It has a water charge air cooler. It’s fitted with ceramic glow plugs for quicker cold weather starts. GM says that a block heater is not required with temperatures above -22F degrees.

The variable geometry turbocharger and the electronically variable intake manifold help the engine deliver the power ratings and lots of low-end torque.

GM says this new 3.0-liter Duramax has a high level refinement, and it is also very quiet. We will have to reserve judgement until we drive it for the first time a little later this month.

This is a high-tech engine, but how will GM’s half-ton truck consumers receive the engine? Will it be a popular choice, or have most light duty truck customers moved on to other engine options? GM is definitely trying to hit all the marks with the power ratings and aggressive pricing. We will have to wait and see.
