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.

Is this '47 Chevrolet a rat rod or a sports car?

These days there are plenty of vehicles that blur the conventional automotive class structures. For instance, was the Honda Crosstour a wagon or an SUV? And what exactly was the Nissan Murano CrossCabriolet? Regardless, those line-blurring cars (or trucks) are out there, and though this one didn't roll off a production line, it's still quite the automotive head-scratcher. Hailing from Missouri, this epic creation is one part mad science experiment, one part 1947 Chevrolet pickup, and one part '95 Mercury Cougar. Add it all up and you get an awesome truck-sports-car hybrid, complete with an outrageous wing and a V8 to boot. And interestingly enough, it's up for sale . RELATED: Check out this Wild-Styled Lamborghini Rat Rod So how does it all come together? According to the listing, the Chevrolet truck cab (which had previously been chopped) was sanded down to bare metal and given a thorough shellacking of clear coat. It was then melded together with the front end of a 1995 Chevrolet S10 pickup truck, and set low to the ground on Bilstein suspension drop spindles. Stance achieved. But instead of fielding an engine from either of those pickups, it pulls its heart from a 2005 Chevrolet Tahoe SUV—a big 5.3-liter V8 heart, that is. It comes backed-up to a GM Turbo 400 automatic transmission. Towards the rear however is where things get really interesting. A Copper Pearl coated tube frame chassis both attaches the rear independent suspension (a la Mercury Cougar) to the racy spoiler, as well as secures the rat rod's rear-mounted radiator, fan, and fuel tank. I'm not quite sure why, but it just looks glorious. RELATED: Reports Say Mid-Engine Corvette Will Arrive in 2018 Inside the vintage cab, the Chevrolet furthers its racing proclivities (it's said to have won burnout and auto-cross events) with a pair of harnessed racing seats, a drift brake, a detachable steering wheel, and a tachometer with oil and temperature gauges, but oddly no speedometer. The shifter is a crescent wrench. And its shift boot? That's a Crown Royal Purple bag. All in all, this grin-worthy Frankenstein creation tallies up bits and pieces from four different vehicles (five if you include the Camaro wheels), which make it truly a mash-up of epic proportions.

2023 Chevrolet Silverado HD reportedly getting mammoth torque

Chevrolet just gave the light-duty Silverado a significant round of updates. It hasn't detailed the changes it has in store for the heavy-duty model yet, but a recent report claims the truck will arrive with significant engine upgrades. Without citing sources, website TFL Truck reported that the current pickup's 6.6-liter Duramax turbodiesel V8 will return in the updated model. Its displacement won't increase, but its output will reportedly grow to 505 horsepower and a mammoth 1,085 pound-feet of torque. To put those figures into perspective, the 6.6-liter makes 445 horsepower and 910 pound-feet of twist in the 2022 Silverado HD; GMC's Sierra HD is available with it as well. Bumping the Duramax's output is a way to keep up with the competition. Arch nemesis Ford offers buyers who have extremely heavy things to tow 475 horsepower and 1,050 pound-feet of torque from a 6.7-liter turbodiesel V8. Over at Ram, the most powerful engine available in a heavy-duty truck posts numbers of 420 and 1,075, respectively. If the report is accurate, Chevrolet will enviably take the horsepower and the torque crowns in the segment. What remains to be seen is what effect the increases will have on the Silverado's towing capacity. As of writing, it's capable of towing up to 36,000 pounds (approximately 15 times the weight of a 2021 Mazda MX-5 Miata). Moving out of the engine bay, the 2023 Silverado HD will receive an updated exterior design that will again help differentiate it from the smaller, light-duty model. We're expecting the next round of updates will also bring new tech features, and it's reasonable to assume that the trim structure will evolve; Chevrolet might notably shift the HD in a more outdoorsy direction to satisfy a growing demand for off-road-focused trucks in the United States. None of this is official; Chevrolet is keeping its lips sealed about the updated Silverado HD. Full details will likely emerge in the coming months, and sales are tentatively scheduled to start in time for the 2023 model year.
