GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks 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. Enthusiast website GM Authority 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 was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. 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 numbers. Fitted to a rear-wheel-drive Tahoe, 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. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban 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 trims but Ford abandoned the segment.

How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:

See the new COPO Camaro's awesomeness from many angles

Considering that the COPO Camaro exists solely to drag race, the action you'll see in this video comes as little surprise. Still, Chevrolet Performance wants to prove that the 2016 model, which uses on the sixth-gen body, is just as adept launching down the strip as previous COPOs. This example may still be testing, but its 427-cubic-inch V8 performs like a champ. The engine's raw muscle, at least when coupled with suitably wide and sticky tires, is enough to lift the front wheels when the driver puts the hammer down off the line. This video from Chevy Performance shows off all the drag-strip action from several unexpected angles. You can watch the rear axle at work and even see the engine under the hood during the run. Our personal favorite is the shot of the launch from underneath the car – it's a perspective you never usually get to see. And, naturally, there are lots of great angles showcasing the car's massive burnout potential. The 2016 COPO Camaro debuted at SEMA in 2015. Buyers have a choice of three V8s, and all of them come with a three-speed automatic gearbox, solid rear axle, and adjustable suspension. Relish this opportunity to see the 2016 COPO Camaro at work, but remember, it's a rare beast. As in years past, Chevy plans to build just 69 of them. Over 5,500 people applied to get one in 2016, and the first example brought $300,000 for charity. Related Video:
