GM CEO Mary Barra predicts mass electrification will take decades

General Motors is allocating a substantial amount of money to the development of electric technology, but Mary Barra, the firm's CEO, conceded that battery-powered cars won't fully replace their gasoline-burning counterparts for several decades. She stressed the shift is ongoing, but she hinted it will be slower than many assume. "We believe the transition will happen over time," affirmed Barra on "Leadership Live with David Rubenstein," a talk show aired by Bloomberg Television. She added that not every car will be electric in 2040. "It will happen in a little bit longer period, but it will happen," she told the host. She was presumably talking about the United States market; the situation is markedly different in Europe and in China, where strict government regulations (and even stricter ones on the horizon) are accelerating the shift towards electric cars. On the surface, it doesn't look like General Motors has much invested in electrification; the only battery-powered model it sells in America in 2020 is the Chevrolet Bolt (pictured), which undeniably remains a niche vehicle. Sales totaled 16,418 units in 2019, meaning the Corvette beat it by about 1,500 sales. In comparison, Cadillac sold 35,424 examples of the aging last-generation Escalade during the same time period. And yet, the company isn't giving up. It has numerous electric models in the pipeline including a slightly larger version of the aforementioned Bolt, the much-hyped GMC Hummer pickup, and an electric crossover assigned to the Cadillac brand. These models (and others) will use the Ultium battery technology that General Motors is currently developing. Its engineers are also working on a modular platform capable of underpinning a wide variety of cars. Bringing these innovations to the market is a Herculean task. EVs may not take over for decades, but Barra and her team must believe their 2% market share will increase significantly in the coming years if they're approving these programs. Autonomous technology is even costlier, more complicated, and more time-consuming to develop. Barra nonetheless expects to see the first General Motors-built driverless vehicles on the road by 2025. "I definitely think it will happen within the next five years. Our Cruise team is continuing to develop technology so it's safer than a human driver. I think you'll see it clearly within five years," she said on the same talk show. Her statement is vague but realistic.

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.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
