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.

Cadillac plans upgrades to its Super Cruise hands-free system

Not content to let Tesla hog the spotlight with lofty claims about its autonomous driving capabilities, Cadillac plans major upgrades to its Super Cruise automated driving system starting next year, when the technology starts rolling out in more models. "The system that we have today, we continue to upgrade," Brandon Vivian, Cadillac's executive chief engineer, told The Verge. 'We have over-the-air re-flash capability, and you'll continue to see us add features and capabilities to Super Cruise going forward." A fellow top Cadillac engineer told the outlet they would not share specifics but said "We want to innovate" as competitors also make advances in self-driving technology. The news comes as Elon Musk says Tesla will launch a driverless robotaxi service in some U.S. cities next year, with "over a million cars with full self-driving, software, everything." The audacious claim hinges on a new Samsung microchip for self-driving vehicles. Last year, Tesla rolled out Navigate on Autopilot, which allows vehicles to change lanes, take exit ramps and choose the correct highway interchange and exit. At the New York International Auto Show, Cadillac announced that it will equip the forthcoming 2020 CT5 sedan with Super Cruise, though not initially. The brand plans to roll out a new model equipped with Super Cruise every six months starting in 2020 and going through the end of 2021, meaning four new models with the technology in two years. Super Cruise previously has been offered only on the CT6 Platinum, and as an option on other CT6 trim levels, along with a three-year OnStar package. It uses cameras, lidar mapping and radar, plus an infrared camera mounted atop the steering column to make sure the driver isn't nodding off, looking away for too long or climbing into the back seat. There's also an LED light bar on the steering wheel and Super Cruise icon on the instrument panel to let drivers know when the system is ready, not ready and ready to deactivate. But the system can't switch lanes and only works on around 130,000 miles of divided highways that GM has mapped with lidar-equipped vehicles. Vivian said the Super Cruise setup in the CT5 will be largely the same as in the CT6 and likened it to "a half step in between" a full next generation of the technology. GM also plans to eventually roll out Super Cruise to its entire U.S. lineup following its introduction in all Cadillac models. Autoblog named Super Cruise the 2019 Technology of the Year winner.

So in case you were wondering, yes, the CTS-V will continue to be one of the auto industry's very best high-performance bargains in its third generation.

This type of car is exclusive, the domain of the few who can access this level of incredible capability.
