GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

Chevrolet Chaparral 2X Vision Gran Turismo could only work in a video game [w/video]

There's something wondrous about the Vision Gran Turismo series of concepts that has let companies go wild with completely imaginary concepts for Gran Turismo. For Chevrolet's crack at the idea, it has taken a page out of its performance past with the Chaparral Can-Am racers of the '60s and '70s, with its designers having reinterpreted that period look for the future of motorsports as the Chaparral 2X. In real life, the 2X looks even better than in earlier photos. The design takes inspiration from someone in a flying suit with head down and arms outstretched, an influence you can really see that in the vehicle's shape. The driver lies facedown inside with the instruments projected onto a visor. Unfortunately, the powertrain here is a complete flight of fancy and works purely in the video game world. It imagines a laser propelled by lithium-ion batteries and an air-powered generation to make 900 horsepower. The 2X has a theoretical top speed of 240 miles per hour and hits 60 mph in a lightning-quick 1.5 seconds. Scroll down to see the concept on video with Chevrolet designers describing their inspiration and read the company's full announcement. It's also downloadable in Gran Turismo 6. Chevrolet to Show Chaparral Vision Gran Turismo Concept Boundary-pushing, Chevy-powered race cars changed motorsports design DETROIT – When racers Jim Hall and Hap Sharp founded Chaparral Cars in 1962, few could have guessed how they would shake up the conformities of the racing world – and fundamentally change it. Through pioneering applications of aerodynamics and aerospace technology, and a partnership with Chevrolet Research and Development, Chaparral Cars advanced the science of racing cars. It also triumphed on the track over well-established sports car companies from around the world, using Chevrolet horsepower. It was that spirit of innovation that inspired the Chevrolet Chaparral 2X VGT concept race car developed for the Vision Gran Turismo project, which celebrates the 15th anniversary of PlayStation® racing game Gran Turismo by inviting manufacturers to give fans a glimpse into the future of automotive design. It will debut at the Los Angeles Auto Show, Nov. 19, and gamers will be able race the Chaparral 2X VGT following the release of an online update for Gran Turismo 6 during the holiday season.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
