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 Escalade reportedly getting 200-hp bump from supercharger

Cadillac is preparing to supercharge the Escalade, according to a recent report. The body-on-frame General Motors SUVs that it shares its basic underpinnings with are allegedly in line to receive a big increase in power, too. Released for the 2021 model year, the fifth-generation Escalade eschewed downsizing and launched with a 6.2-liter V8 as its standard engine. It develops 420 horsepower and 460 pound-feet of torque when it's naturally aspirated, and Motor Trend learned from an anonymous source that the optional supercharger will increase the first figure to anywhere between 600 and 625. The eight's torque output will undoubtedly go up, too. The supercharged Escalade won't outgun the sold-out Dodge Durango SRT Hellcat, which gets 710 horses, but it will pack a serious punch. It doesn't sound like the V8 will require significant modifications to handle the extra power because the supercharger kit will likely be installed by dealers, not on the assembly line. This strongly suggests that it's more of a bolt-on job than one that requires taking the engine out and apart to install stronger connecting rods and forged pistons, for example. ECU tweaks will be part of the package, too, and the fuel delivery system may require some upgrades. Interestingly, Motor Trend learned from Texas-based Hennessey that the SUV's ECU is locked to tuners, which adds credibility to the report. Motorists who want more power will need to go through official sales channels, then. Bigger brakes and a firmer suspension won't be part of the package — at least not yet. The same source outlined a true high-performance evolution of the body-on-frame behemoth that will be quicker and tighter to drive. Oddly, it's not being developed by the engineers in charge of Cadillac's V-branded models, according to the report. If the report is accurate, we'll learn more about the supercharged Cadillac Escalade in the coming months, and it might go on sale in time for the 2022 model year. Expect the supercharger to come with a four-digit price tag. Chevrolet's Tahoe/Suburban and GMC's Yukon/Yukon XL will reportedly be available with a supercharger, too.

2018 Cadillac XTS does its best CT6 impression

Although the Cadillac sedan lineup almost exclusively consists of rear-drive sedans, one last bastion of the old front-drive Caddy exists in the XTS. And it looks like the old-school XTS isn't going anywhere, since it just got a refresh that makes it look more like the CT6 and the CTS. This of course is a bit ironic considering the fact that the CT6 will look different in the near future. Until then, though, this update does make the XTS look more up-to-date. The main part of the headlights end higher up on the front fascia, while a strip of LED accent lights waterfall down the front bumper. The grille has slightly more sculpted slats, and the front badge has been scaled down a bit. There are no longer creases that unify the main grille and the lower one in the bumper, which help the car appear lower and wider than the outgoing model. At the back, the license plate position has been moved down to the bumper, and the trunk lid has more lines and creases. The taillights now have horizontal elements that extend toward the middle of the car. The exhaust finishers and the reverse light also look larger and more prominent now. The refreshed XTS also brings a couple of new trim options. There are new wheel designs both in 19- and 20-inch sizes. Inside, XTS buyers will be able to choose from three new color and upholstery combinations. Two of them, however, are exclusive to the Platinum trim level and come with semi-aniline leather seats. There's not really anything new mechanically with the 2018 XTS. The only major change seems to be a new tire design that is quieter and provides a smoother ride. Otherwise, the XTS will remain available with either the standard 3.6-liter V6 making 304 horsepower, or the optional 410-horsepower twin-turbocharged 3.6-liter V6 in the V-Sport model. The standard engine comes with either front-wheel drive or all-wheel drive, and the V-Sport is only available with all-wheel drive. Pricing has yet to be released for the 2018 model year.
