GM's latest production delays: Colorado/Canyon, Cadillac CT4/CT5, Camaro

DETROIT — General Motors Co extended production cuts in North America on Wednesday due to a worldwide semiconductor chip shortage that has impacted the auto sector. The U.S. automaker said its Wentzville, Missouri, assembly plant would be idled during the weeks beginning March 29 and April 5. It will extend down time at its plant in Lansing, Michigan, which has been idled since March 15, by two weeks. The action was factored into GM's prior forecast that it could shave up to $2 billion off this year's profit, spokesman David Barnas said. GM did not disclose how much volume would be lost by the move, but said it intended to make up as much lost production as possible later in the year. The chip shortage came as North American auto plants were shut for two months during the COVID-19 pandemic last year and chip orders were canceled, and as demand surged from the consumer electronics industry as people worked from home and played video games. That's now left carmakers competing for chips. Semiconductors are used extensively in cars, including to monitor engine performance, manage functions for everything from steering to automatic windows, and in sensors used in parking and entertainment systems. Vehicles affected by the GM production cuts include the mid-sized pickup trucks, the Chevrolet Colorado and GMC Canyon in Missouri, and the Cadillac CT4 and CT5 and Chevy Camaro cars in Michigan. Meanwhile, GM said its San Luis Potosi, Mexico, assembly plant, idled since Feb. 8, will resume production with two shifts beginning the week of April 5. Last week, GM said it was building certain 2021 light-duty full-size pickups without a fuel management module, hurting their fuel economy performance by one mile per gallon. Exacerbating the shortage is a recent fire at a Renesas Electronics chip plant in Japan. Barnas said GM was assessing the impact of the fire.  

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.

2023 Cadillac Lyriq vs Tesla Model Y, Audi E-Tron, Jaguar I-Pace | Specs compared

The 2023 Cadillac Lyriq is the latest electric luxury crossover to enter a quickly growing segment. It brings with it the company's trademark creased design language along with high-tech features and an impressive amount of range. The Cadillac also happens to have a price and specifications that put it square in the middle of a competitive group, so we had to line up the numbers to see how it compares. We've gathered up a selection of premium electric crossovers including the Tesla Model Y, Audi E-Tron and Jaguar I-Pace, all of which seem like the closest rivals for the Cadillac. We've assembled all the raw numbers in the chart below. We've also got some additional analysis below that. And now, onto the data. Power, range, efficiency Interestingly, the Cadillac is the least powerful of the bunch. This is a bit surprising considering that GM will have a 1,000-horsepower electric Hummer pickup coming out soon. But in the Lyriq, Cadillac only uses a single electric motor powering the rear wheels. While its 340 horsepower and 325 pound-feet of torque should be more than adequate, it falls short of all the dual-motor, all-wheel-drive competition. Because Tesla does not provide horsepower or torque numbers, we're not sure how much the base model makes. We assume it's close. The true power fiends will likely want the optionally available Model Y Performance, though. It also doesn't have publicized power numbers, but its 0-60 mph time of 3.5 seconds suggests its substantially more powerful than the other crossovers, here. Power is all well and good, but range is arguably more important for an electric car. The Tesla is on top, here. The base Long Range trim has an estimated range of 326 miles. The company doesn't specifically say how large the battery is for it or the Performance, which goes 303 miles. The Cadillac is close behind with a current estimate of more than 300 miles on its 100-kWh battery. Cadillac doesn't say whether that number is the gross amount or the usable amount. The Audi and Jaguar lag behind with less than 250 miles from their 95- and 90-kWh batteries, respectively. Audi is the only company that notes that the usable capacity is less than the total, which is a common strategy employed to extend the life of the battery and to maintain consistent ranges over time. 2020 Audi E-Tron View 13 Photos While not as broadly discussed as range, we also wanted to touch on efficiency.
