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.

2016 Chevrolet Camaro: Notes from the reveal

The 2016 Chevrolet Camaro debuted Saturday evening in Detroit at an enthusiast-oriented event near the city's IndyCar course. While the big news was the Camaro's 200-pound weight loss, tighter chassis, and a snorting new V8, plenty of other morsels of Camaro info came out. Here's some of the more interesting stuff we heard. • The 2.0-liter inline four-cylinder is the first turbocharged engine in a Camaro. • The LT1 borrowed from the Corvette Stingray marks the third time a Camaro has used an engine with that badge. It was previously used in 1970-72 (Z/28), 1993-97 (Z/28), and 1996-97 (SS). • The Camaro was revealed in a tent before nearly 1,000 enthusiasts, General Motors executives (including CEO Mary Barra) and mere feet from the Grand Prix course where IndyCars will run in two weeks. • Chevy hopes to continue to attract new customers with the Camaro and said 63 percent of the fifth-generation buyers were new to the brand. • GM product boss Mark Reuss neatly summed up the Camaro's handling character. "It's wicked fast and extremely nimble." • Reuss on the design goal: make it "look like a car for tomorrow instead of a car from yesterday." • Reuss' first car was a 1967 Camaro, and he's reiterated his passion for the car. "People want to be seen in a Camaro, and that never goes away." • Chevy North America president Alan Batey said he plans to line up a red Camaro as soon as the order bank opens. We assume he'll have early access to that. • Though the appearance is similar, the sixth generation of the Camaro appears a little sleeker and is more aerodynamic thanks to 350 hours in the wind tunnel. Only two parts, the SS badge and the rear bow-tie emblem, are carryover. • Al Oppenheiser, the Camaro's chief engineer, said most of the options (except Magnetic Ride Control, which is SS exclusive), will be offered on the inline four. The engine will be capable of propelling the Camaro to a sprint to 60 miles per hour in well under six seconds. "We don't want to ... make it feel like an excuse car," he said. • Without revealing specifics, Oppenheiser said every Camaro variant will be faster than the model it replaces. •The interior is vastly improved. We got an up-close look in the cabin of one of the cars revealed with a red and white layout, and the materials are much better. The setting is more colorful, and 24 different ambient lighting shades are available. Related Video:

GM to cut production at 5 plants in North America, kill several models

DETROIT/WASHINGTON — General Motors Co said on Monday it will cut production of slow-selling models and slash its North American workforce in the face of a stagnant market for traditional gas-powered sedans, shifting more investment to electric and autonomous vehicles. The announcement is the biggest restructuring in North America for the U.S. No. 1 carmaker since its bankruptcy a decade ago. GM said it will take pre-tax charges of $3 billion to $3.8 billion to pay for the cutbacks, but expects the actions to improve annual free cash flow by $6 billion by the end of 2020. GM plans to halt production next year at three assembly plants: Lordstown, Ohio, Hamtramck, Michigan, and Oshawa, Ontario. The company also plans to stop building several models now assembled at those plants, including the Chevrolet Cruze, the Cadillac CT6 and the Buick LaCrosse, the sources said. Sources said the Chevrolet Volt, Impala and Cadillac XTS would also be discontinued. Signs of the demise of six passenger-car models have been swirling since July. Plants in Baltimore, Maryland, and Warren, Michigan, that assemble powertrain components have no products assigned to them after 2019 and thus are at risk of closure, the company said. It will also close two factories outside North America, but did not identify those plants. The AP reported that 14,700 jobs would be affected. Some 8,100 of those would be white-collar jobs reduced through buyouts or layoffs. The No. 1 U.S. automaker signaled the latest belt-tightening in late October when it offered buyouts to 50,000 salaried employees in North America. The company also said it will cut executive ranks by 25 per cent to "streamline decision making." Some 6,000 factory workers could lose their jobs or be transferred to other plants. Its shares were last up 6.2 percent at $38.16. Tariff 'headwinds' and cost-cutting GM Chief Executive Officer Mary Barra told reporters on Monday the company can reduce annual capital spending by $1.5 billion and increase investment in electric and autonomous vehicles and connected vehicle technology because it has largely completed investing in new generations of trucks and sport utility vehicles. Some 75 percent of its global sales will come from just five vehicle architectures by early in the 2020s. It plans to reduce annual capital spending to $7 billion by 2020 from an average of $8.5 billion a year during the 2017-2019 period.
