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.

2022 Cadillac CT4-V Blackwing First Drive Review | A magnificent sunset

Rising from the ashes of the ATS-V, the 2022 Cadillac CT4-V Blackwing represents the ultimate (in the purest sense of the word) in compact performance from GM’s luxury brand. The name Blackwing was originally applied to a stillborn, twin-turbocharged V8 destined for a new generation of luxury sedans, but has been repurposed as a symbol for CadillacÂ’s stubborn insistence on doing right by its performance heritage, right up to the end. Yes, the end. The last gasp. The grand finale. Swan song. Farewell tour. Whatever version of finality works best for you, apply it here, because Blackwing represents the gasoline-powered CadillacÂ’s final form. There are two key components to a sport sedan: a kick-ass powertrain and a chassis than can wrangle it. Check and check. A modern and powerful twin-turbo V6 resides under the CT4-V Blackwing's hood, and it rides on the latest and greatest revision of GMÂ’s global Alpha platform, which evolved from the same basic underpinnings of the ATS, CTS and Chevy Camaro. A stretched and widened version is the foundation for the CT5 (look for our review of that car's Blackwing next week). In transitioning from ATS to CT4, Cadillac decided to reposition and price its smallest sedan against EuropeÂ’s subcompacts. In the grand tradition of CadillacÂ’s sporty four-doors, this makes it a size mismatch. ItÂ’s almost as large on the outside as a BMW 3 Series or Mercedes C-Class, rather than the front-wheel-drive based 2 Series Gran Coupe and CLA-Class with which the CT4 nominally competes on price. This generational re-branding also resulted in a new, very different approach to high-performance models wearing the letter V. Before, they represented the pinnacle of their respective nameplates, but now, a -V represents the mid-grade offering. Upgraded certainly (limited-slip rear differential, more power, adaptive suspension) but positioned against AudiÂ’s S and BMWÂ’s M-Sport models. Cadillac even calls it "CT4 V Series" in certain places because the situation wasn't confusing enough. And although there's nothing ambiguous about the Blackwing's position atop the CT4 hierarchy, Cadillac's have-their-cake-and-eat-it-too approach to the CT4Â’s positioning still makes things a little hinky.

Woman thwarts car thieves by jumping on hood

When a pack of car thieves tried to steal a Milwaukee-area woman's car at a gas station, she didn't run for help. Oh no. She hulked out, jumped on the hood, and screamed her head off until the thief finally ran off. According to WISN, Melissa Smith was gassing up her white Subaru Outback at a BP station near Milwaukee's historic Third Ward on the afternoon of May 24. As she stood there pumping gas and minding her own business, a black Cadillac swung slowly around the front of the Subie and came to a stop just off the front left corner. As Smith turned her back to hang up the pump nozzle, a dude bailed out of the Caddy, crouched down, and snuck into the Outback's driver's seat. "I didn't see him till I saw him get into my car. Or someone was in my car, and had my, 'Oh, hell this isn't happening to me today' moment," Smith told WISN. As soon as she saw the thief in her car, Smith ran around the front then leaped on to the hood. She started yelling and pounding on the windshield as the thief tried to pull away from the pump, but he refused to stop. He tried a couple quick stops in an attempt to shake her off, but to no avail. "He looked at me, and he laughed at me, which really irritated me," Smith said. "He was laughing while I was on my car, and he was trying to throw me off, so zero remorse." Smith clung to the Subaru, shouting and pounding until the thief gave up. He abandoned ship, jumped back into the Caddy, and the group of thieves sped away. Unfortunately, when the thief bailed he left the Subie in gear with Smith still holding on for dear life. "Then I had to chase my car into the street and stop it before it hit somebody else," Smith said. Thankfully, Smith was unharmed in the incident, but the crooks got her purse, phone, wallet, and sunglasses. Milwaukee police are still looking for the suspects, who they say stole the black Caddy before trying to steal Smith's Subaru.
