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.

Here are a few of our automotive guilty pleasures

It goes without saying, but I'll say it anyway. The world is full of cars, and just about as many of them are bad as are good. It's pretty easy to pick which fall into each category after giving them a thorough walkaround and, more important, driving them. But every once in a while, an automobile straddles the line somehow between good and bad — it may be hideously overpriced and therefore a marketplace failure, it may be stupid quick in a straight line but handles like a drunken noodle, or it may have an interior that looks like it was made of a mess of injection-molded Legos. Heck, maybe all three. Yet there's something special about some bad cars that actually makes them likable. The idea for this list came to me while I was browsing classified ads for cars within a few hundred miles of my house. I ran across a few oddballs and shared them with the rest of the team in our online chat room. It turns out several of us have a few automotive guilty pleasures that we're willing to admit to. We'll call a few of 'em out here. Feel free to share some of your own in the comments below. Dodge Neon SRT4 and Caliber SRT4: The Neon was a passably good and plucky little city car when it debuted for the 1995 model year. The Caliber, which replaced the aging Neon and sought to replace its friendly marketing campaign with something more sinister, was panned from the very outset for its cheap interior furnishings, but at least offered some decent utility with its hatchback shape. What the two little front-wheel-drive Dodge models have in common are their rip-roarin' SRT variants, each powered by turbocharged 2.4-liter four-cylinder engines. Known for their propensity to light up their front tires under hard acceleration, the duo were legitimately quick and fun to drive with a fantastic turbo whoosh that called to mind the early days of turbo technology. — Consumer Editor Jeremy Korzeniewski  Chevrolet HHR SS: Chevy's HHR SS came out early in my automotive journalism career, and I have fond memories of the press launch (and having dinner with Bob Lutz) that included plenty of tire-smoking hard launches and demonstrations of the manual transmission's no-lift shift feature. The 260-horsepower turbocharged four-cylinder was and still is a spunky little engine that makes the retro-inspired HHR a fun little hot rod that works quite well as a fun little daily driver.

Recharge Wrap-up: Lyft partners with Didi Kuaidi, Cadillac uses ultracapacitors

Lyft and Chinese on-demand transportation venture Didi Kuaidi have announced a partnership. Additionally, Didi Kuaidi is investing $100 million in Lyft. The two ridesharing companies will share technology and provide interoperability between platforms. For users, this means it will be easier to get around when traveling between the US and China. "In today's rideshare environment, where every region presents a unique set of challenges and opportunities, partnering with the homegrown leader is the winning approach to Chinese expansion," says Lyft President and co-founder John Zimmer. Learn more in the video above, and in the press release below. Car2go has announced service in Miami Beach, FL. Beginning October 1, the one-way carsharing service will expand its boundaries beyond its current Miami service area to include neighboring Miami Beach.

Cadillac will use ultracapacitors in its stop-start systems for 2016. Rather than relying on battery power to run electrical systems while the engine is not running, the utracapacitors can provide a stable flow of energy without losing lifespan to repeated cycling. Supplied by Maxwell Technologies, the ultracapacitors are also lighter than batteries and, according to Cadillac, provide smoother restarts. The 2016 models to use the updated stop-start technology as standard will be the ATS and CTS, with the exception of the V performance variants. Read more at Green Car Reports.
