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.

Hotter Cadillac CT5-V could use the CTS-V's 6.2-liter V8

Cadillac is in the final stages of testing the high-performance variant of the CT5, prototypes are racking up miles all over the world, and a recent report sheds light on the engine screaming between its punched-out fenders. It's a V8, to no one's surprise, but it's not the twin-turbocharged, 4.2-liter unit many believed the sedan would use. Sources familiar with Cadillac's product plan told Car & Driver the hotter CT5 — whose name hasn't been revealed yet — will receive an updated version of the supercharged 6.2-liter V8 that powered the mighty CTS-V. It developed 640 horsepower in the firm's last German-bashing super-sedan, though where engineers will peg the CT5's output remains to be seen. It will roast the rear tires through a paddle-shifted automatic transmission. The publication explained Cadillac chose the 6.2-liter because it's more compact than the 4.2-liter Blackwing engine it developed for the CT6. The former features a pushrod design, while the latter gets twin overhead cams that make it taller and wider. The CT5 is a new model, but its Alpha platform is older than Cadillac's newest V8. Cadillac hasn't announced what will power the flagship CT5. The model is tentatively due out in showrooms before the end of 2020, so we expect to learn more about it in the coming months. Seeing it in the metal for the first time during the 2020 Detroit Auto Show in June isn't entirely out of the question. What's next? If the report is accurate, the much-hyped Blackwing may end up being an orphan engine. It was developed specifically for the Cadillac brand, and inaugurated by the CT6-V that recently went out of production. The many rumors claiming General Motors will put the engine in other models to recoup its investment are falling like dominoes. It won't fit in the CT5, so there's no reason to believe it will end up in the smaller CT4; its flagship version will likely arrive with a twin-turbocharged, 3.6-liter V6 borrowed from the ATS-V. An earlier report claims the next-generation Escalade won't use the Blackwing, either, because making it fit would cost too much. Looking beyond Cadillac, the only General Motors-owned brand that could use the Blackwing is Chevrolet, since we can't imagine the GMC Yukon will get it if the Escalade doesn't. The Tahoe/Suburban duo is off the table, too.

Cadillac prices new XT5 from $39,990

Keen to put your deposit down for a new Cadillac XT5, but waiting to find out how much you'll need to set aside? Well the wait is over, friend, as Cadillac has announced pricing for the new crossover. US pricing starts at $38,995, which works out to $39,990 once you factor in the standard $995 destination charge. That's only $1,390 more than the now wreathless brand charged for the outgoing SRX, which the new XT5 replaces and which carried a starting price of $38,600 (delivered). It also undercuts the competition from most other luxury automakers. The BMW X3 ($40,495), Audi Q5 ($40,900), Lexus RX 350 ($42,850), and Infiniti QX70 ($45,850) each start at a higher base price than the Caddy. However the Mercedes GLE stats marginally lower at $39,875, and the Lincoln MKX goes for significantly less at $37,935 – all prices including destination charges. Of course, that starting price is just for the base model with front-wheel drive. All-wheel drive is optional on Luxury and Premium models, but comes standard on the top-spec Platinum. Step that far up the ladder, though, and you'll be looking at $63,495 (delivered).

XT5 enters the strongest category in the luxury automotive space, the midsize luxury crossover segment, where Cadillac set sales records in 2015. "The arrival of this sophisticated new crossover positions Cadillac well, as XT5 enters the most popular segment in the global luxury market," said Cadillac President Johan de Nysschen. "It's pivotal to our ongoing growth, which is why we've developed XT5 from the inside out to provide customers more space, more technology, more luxury and more efficiency." The XT5 is the first in a series of upcoming luxury crossovers carrying the "XT" designation, a key aspect of the brand's product-driven global growth plan. The new luxury crossover joins Cadillac's lineup immediately following the new range-topping CT6 Sedan, as the brand enters a new phase of product growth. The XT5 is the next chapter in elevating the Cadillac brand: it is bold, distinctive and sophisticated with enhanced driving dynamics. This new crossover perfectly reflects Cadillac's positioning in the luxury automotive marketplace, de Nysschen said.
