GM's Duramax diesel engine: a strong ally

Traditionally, the GM family diesel engines were still found with the company's HD vehicles, primarily the 2500 and 3500 series pickups. With these, they offered impressive towing capabilities, combined with more reasonable odds at the consumption.

Two years ago, GM decided to extend this option to the 1500 series models, both the Chevrolet Silverado and the GMC Sierra. And since these vehicles lend their structures to the family's SUVs, the latter also offer the Duramax Diesel mechanics introduced by the company. For example, Tahoe, Suburban and Yukon pickup trucks and SUVs can also accommodate the 3.0-liter 6-cylinder turbo-diesel, an engine that delivers 277 horsepower and incredible torque of 460 pound-feet.

Efficiency above all

With this engine under the hood, all vehicles that benefit from it become efficient at every level. First, it should be mentioned how impressive the power is as soon as you touch the accelerator. The horses have something to do with it, of course, but the availability of torque from 1,500 rpm makes all the difference.

And the amazing thing is that no matter what you harness in the back, the engine never seems to force; it performs flexibly at all times.

As for the weight that can be towed with a model equipped with the 6-cylinder Diesel Duramax, it fluctuates from one model to another, but we swim in a really interesting range, around 8000-8500 pounds with SUVs, 9300 books with vans.

Finally, the other advantage is at the pump that you see it. While with a conventional V8 engine, the average fuel consumption of a full-size SUV or pickup truck can vary between 13 and 15 liters per 100 kilometers, it is 8.5 to 10.5 liters with a model equipped with 6-cylinder Diesel Duramax.

That’s a huge difference and for those who ride a lot, the savings await you in the long run.
