General Motors<\/a> temporarily stopped taking orders for trucks<\/a> and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production.<\/p>\n

Enthusiast website GM Authority<\/a><\/em> learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There’s no official word on precisely what the problem<\/a> was linked to and whether it was related to the on-going chip shortage<\/a> that’s wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks.<\/p>\n

Called LM2 internally, the six is available in Chevrolet’s Tahoe<\/a>, Suburban<\/a>, and Silverado 1500<\/a> and in GMC’s<\/a> version of these trucks. It’s also an option in the Cadillac Escalade<\/a>. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy<\/a> numbers. Fitted<\/a> to a rear-wheel-drive Tahoe<\/a>, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer<\/a>.<\/p>\n

Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban<\/a> sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500<\/a> trims but Ford<\/a> abandoned the segment<\/a>.<\/p>\n
