Just final yr, each Detroit automaker supplied an environment friendly and highly effective diesel engine in its half-ton pickup trucks. But Ford canceled its F-150’s PowerStroke V6 forward of the 2022 mannequin yr. Then Ram introduced it might solely construct its EcoDiesel V6 by the tip of 2022. The last half-ton truck with a diesel engine choice is the Chevrolet Silverado/GMC Sierra from General Motors with its 3.0-liter Duramax diesel I6.
What diesel is within the Silverado 1500/Sierra 1500?
General Motors builds a turbocharged diesel I6 for its half-ton vans, badged because the Duramax. In both the GMC Sierra 1500 or the Chevrolet Silverado 1500, this 3.0-liter powerplant makes 460 lb-ft of torque and will get as much as 30 mpg on the freeway.

GM first supplied a 6.2-liter diesel V8 in its C/Okay vans method again in 1982. Since then, Diesel engines have been prized by pickup truck patrons for each their energy and their effectivity. The latest Duramax 3.0 is not any completely different. But GM paired the advantages of diesel with a tried-and-true engine format to extend dependability and reduce shifting elements.
While the newest diesel half-tons from Ram and Ford have been turbocharged V6 engines, GM provides a turbocharged inline six-cylinder. According to GMC‘s Assistant Chief Engineer, John Barta, “The inline six is a naturally balanced engine.”
What does this imply for truck house owners? Barta reveals, “We don’t want steadiness shafts and the engine solely has one set of overhead cams. Fewer elements imply much less weight and friction and enhanced effectivity. It’s a win-win design that gives gasoline financial system and easy operation.”

One of the weaknesses of previous diesel engines has been their sluggish acceleration. Engines designed to launch shortly have needed to sacrifice effectivity.
Barta mentioned, “The 3.0L Duramax was designed to be a ‘no excuses’ engine choice that gives wonderful gasoline effectivity, nice low-end torque and easy responsive operation.”
GM leveraged superior know-how to steadiness energy and effectivity. For instance, the three.0 can change the pitch of its turbocharger blades to shift from responsive acceleration to environment friendly operation.
Barta added, “Also, new to the Duramax diesel engine household, the three.0L makes use of a variable consumption valve, we name it the swirl valve, to tumble or swirl the air at low rpm to get higher combustion and energy with much less gasoline.”

Barta feels his engine is a success: “The low-end torque and broad torque band offer you a satisfying punch that speaks to energy and functionality whereas doing it at low noise ranges and providing a mixed common gasoline financial system within the mid-20s.”
The success of the Duramax 3.0 in each Chevrolet Silverado 1500s and GMC Sierra 1500s speaks for itself. It is not any surprise that on the planet of half-ton vans, the Duramax 3.0 is the final diesel standing.
