General Motors Company [NYSE:GM] is introducing a new generation of its Duramax V-8 diesel engine in its 2017 Chevrolet Silverado and GMC Sierra 2500HD pickup trucks.

The automaker on Saturday confirmed the engine’s output at 445 horsepower and 910 pound-feet of torque.

That makes it 5 hp more powerful than Ford Motor Company’s [NYSE:F] Power Stroke turbocharged 6.7-liter V-8 diesel, though the Ford has a more important 15 lb-ft torque advantage. Nevertheless, torque in the latest Duramax represents a 19 percent gain on the outgoing unit. And best of all, 90 percent of this grunt is available from as low as 1,550 rpm. GM says the new engine is also much more refined, offering quieter, smoother operation.

There is also an interesting air intake system, distinguished by a new hood scoop. Around 60 percent of the air going into the engine is via this intake, helping air entering the engine to remain cool even when the unit is running hot.

But the air also needs to be dry. That’s why the intake features an air/water separator where humidity or mist is turned into larger, heavier droplets that can be collected before the air enters the engine. Testing of this system was conducted in hot, humid days at elevations of up to 11,000 feet.

The new engine will be available in GM’s big pickups starting from early 2017. It will enable a maximum conventional towing rating of 20,000 lb and a max fifth-wheel/gooseneck tow rating of 23,300 lb.
