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.

Weekly Recap: BMW rolls out ambitious plug-in hybrid electric plan

"We believe that for the United States, this is going to be very important." – Julian Arguelles Let there be no doubt, BMW is serious about electric vehicles. The German automaker said this week it will make plug-in hybrid versions of all of its core models, an aggressive move that demonstrates its commitment to electric propulsion systems. BMW did not specify which vehicles will get the plug-in systems or provide a timeline for when they will arrive. But the announcement is clearly more than blustering, and the company revealed a 3 Series plug-in prototype this week at an event in France. BMW said the 3 Series uses a version of its 2.0-liter turbocharged four-cylinder engine (240 horsepower, 300 pound feet of torque) with an electric motor sandwiched between the engine and transmission in place of the torque converter. It has an all-electric range of 22 miles. A plug-in X5 with the same powertrain was also displayed alongside the 3 Series, though the X5 has been on the auto-show circuit for more than a year, including a recent stop in Los Angeles. Those two vehicles use "eDrive," and BMW's plans represent the first widespread transfer of its technology from development of the i3 and i8 models to more mainstream products. BMW said it's developing electric powertrains so they can be deployed rapidly across its range, and they are flexible enough to be used with fuel cells in future products. Enticingly, BMW is also working on a "Power eDrive" system, which debuted in a 5 Series GT concept at the event in France. This setup has two electric motors powered by a 20-kilowatt-hour battery pack, and when teamed with a four-cylinder turbo, pump out about 670 hp. Reinforcing BMW's commitment, the company will add more than 200 jobs at its factory in Dingolfing, Germany, to support electric-vehicle development. The moves come as BMW and other automakers diversify their portfolios while fuel economy and emissions regulations are getting tighter around the world. The United States has set a 54.5-mpg CAFE requirement for the 2025 model year. BMW said the electric vehicles were developed with an eye toward the US market, its government policies and its wide-ranging commuting styles. "We believe that for the United States, this is going to be very important," spokesman Julian Arguelles said. Ben Scott, a senior analyst in London with automotive research firm IHS, said BMW's moves are expensive – but necessary – to keep pace with the market.

How two-state Chevy Spark EV outsold 50-state Volt last month

Is it really just about price? Last month, the Chevy Spark EV got a sizable price drop of $1,500 alongside a lowered lease price of $139 a month (down from $199). Those numbers, particularly that cheap lease, had a tremendous impact on how many all-electric Sparks GM sold last month. There were 920 Spark EVs sold in April, and the Spark EV is available in only two states: California and Oregon. Sales will start in Maryland in the third quarter of 2015, but there are no pre-orders taking place there, so all 920 were West Coast sales. To be more precise, there were about 864 Spark EV leases signed last month, since 94 percent of those 920 sales were retail leases. As Annalisa Bluhm from Chevrolet communications told AutoblogGreen, that level was, "simply insane." "In those states which offer Spark EV, you can get a 1LT Spark EV for less than a 1LT Spark, with more features" Bluhm said. "Factor in that you will save approximately $82 per month by abstaining from gas, and it's easy to see why people went crazy for the Spark." Let's put 920 into perspective. For one thing, it's crazy up from the 151 Spark EVs sold in March 2015 and the 97 sold in April 2014. It's also almost as many as GM sold all last year, and way more than two years ago. The General sold 653 Spark EVs in 2013 and 1,146 in 2014. To throw in a comparison with GM's longstanding plug-in champion, the aging Volt, the Spark EV came out ahead in the monthly tally for the first time ever. In April, the Volt sold 905 units. The plug-in hybrid's best-ever sales month was August 2013, when it sold 3,351 units. Counting all models and powertrains, Chevy sold 3,743 Sparks in April. So, does this success mean that Chevy is looking to bring the Spark EV to more markets? Bluhm said that GM is considering other states and is always looking at the business case, but has "nothing to announce yet."
