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 CT4 and CT5 high-performance V cars spied

This summer, Cadillac teased much more impressive V-series models than the lukewarm CT4-V and CT5-V. Now we get a better look at both super sedans, each one boasting more aggressive, but subtle visual upgrades. Normally we would talk about the visual changes to each car individually, but the changes are nearly identical between the cars. They both get deeper chin spoilers and lower side skirts. The lower grille opening now features slatted sections on either end. The headlights, main grille and hood all look unchanged from the regular V models. The same goes for the rear bumpers and tailpipes. The rear spoilers on both are much taller, though. The wheels on the CT4 look about the same as the CT4-V, but the CT5 wheels look a bit different with more detail. We also get a good look at the wheel-filling brakes. Cadillac hasn't said anything concrete about the specifications of the hotter CT4 and CT5 models, except that they'll definitely be faster than the revealed V models. One thing we do know, thanks to our spy photographer's video from earlier this year (shown above), the CT5 will get a V8. Our bet is on it being the Blackwing twin-turbo V8 that's available in the CT6-V and CT6 Platinum. It would probably have at least the same output at the CT6-V at 550 horsepower and 640 pound-feet of torque. Expect the 10-speed automatic transmission to carry over with it. This drivetrain would also open up the possibility of all-wheel drive. As for the fast CT4, it could potentially revive the ATS-V's twin-turbo V6 with 464 horsepower and 445 pound-feet of torque. It would probably also get a 10-speed automatic and maybe all-wheel drive as an option.

Cadillac Lyriq EV debut delayed by Covid-19 virus

The, coronavirus, otherwise dubbed Covid-19, has claimed another large gathering. General Motors canceled the public debut of its coming Cadillac Lyriq crossover, planned for April 2 in Los Angeles, due to fears over the continued spread of the virus. With more than 14 confirmed cases of residents with Covid-19, Los Angeles declared a state of emergency last week. Michael Albano, a communications director at GM, said in an e-mail to The Verge that "Our top priority is the safety of our media guests and employees." At the time of writing there's no word on a potential new date for the reveal for the highly anticipated crossover that GM just announced last week at a private event in Warren, Michigan. However, the automaker provided Autoblog with a statement that read, in part, "Please know we are working to reschedule the reveal as soon as possible." What we know about the Lyriq is just as compelling as what we don't know. There XT5-sized people hauler will be out to dazzle in every way, with a ton of weight on its shoulders — many will be judging GM's and Cadillac's past and claimed preparedness for the future based on this one offering. The Lyriq will be the first GM EV to sit on a new EV architecture the engineers call BEV3 and the marketers call Ultium, with battery capacities up to 200 kWh and a potential range of 400 miles. Speaking of which, GM just applied to trademark the term Tecra with the US Patent and Trademark Office, so we could be in for more information on innovative battery systems in the not-too-distant future. The automaker could forgo a public debut for the time being and opt to livestream the event. Or, who knows, it's possible the Detroit Auto Show just garnered itself a whopping debut for the show's debut event in June; the first rendering of the Lyriq aired at last year's Detroit show.
