The 2023 Chevy Silverado 1500 is one of our heaviest hitters (and haulers!) here at West Chevrolet of Knoxville. It will now enjoy its fourth model year standing strong as the latest-generation pickup, and we guarantee that it will sport one fantastic feature that everyone has been asking about: the brand-new 3.0-liter Inline-6 LZ0 turbodiesel Duramax engine. GM Authority reported this week that the new diesel engine will be more widely available to order, after the production restraints that affected this year’s output have been lifted.
This hefty and capable Duramax is ready to roll, and available to order for the 2023 Chevy Silverado 1500 LTZ and High-Country trim levels. You can also enjoy its powerful presence on the LT, RST, and LT Trail Boss trim levels and shares a few high-octane and very desirable things in common with the LM2 including turbocharged aspiration, 3.0-liters of displacement, and an inline six-cylinder design. The LZ0 acts as a replacement for the LM2 in the 2023 model year providing more output and is rated at 305 horsepower and 495 lb-ft of torque.
Every time these heavy-hitting and brand-new engines appear on the scene, it is quite impressive to marvel at the mechanical traits that make them so amazing, as the LZ0 diesel features fully upgraded steel pistons, a revised combustion bowl, brand-new fuel injectors, and a refined turbocharger compressor. All this refined and expertly built goodness is mated to a 10-speed automatic transmission and is assembled by the hard-working and proud individuals at the GM Flint Engine Operations plant in Michigan.
Underneath it all is the GM T1 Platform, built by the crew on duty and always cranking out sheer perfection at the GM Fort Wayne plant in Indiana. As the price of diesel fuel remains a bit high in the US, efficiency such as the 24-mpg combined found here will be a welcome trait. In a separate blog post earlier this year, Motorbiscuit also confirmed that this new LZ0 Duramax engine’s reliability is so thorough that it has extended its recommended inspection to the 200,000-mile mark, alleviating the need for the somewhat difficult task of replacing the variable valve oil pump belt at 100,000 miles.
Engineers at the helm of developing the Duramax spent a lot of time assuring that the rig would start up quicker and discovered some fine tuning that had to take place during the crank design. It also uses smaller, steel pistons instead of aluminum, and needed a longer stroke to maintain 3.0-liter displacement. There are also brand-new injectors that assist with turbocharger tuning and an entirely reworked cylinder head along with a completely revamped cooling system. What all these components collaborate to achieve is a high satisfaction level with the smooth and quiet power the diesel provides, and the true reliability and grit drivers have praised Chevy trucks for all of these fantastic years!
