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.  

2016 Camaro gets most revealing tease yet

Chevrolet started its long teaser campaign for the 2016 Camaro by just revealing the exhaust manifold and front frame, but as time has passed the company has slowly unveiled more. In the latest glimpse ahead of the pony car's May 16 debut, we're actually getting to see the model's profile completely undisguised. As suggested by the recent tease of the rear and hood, the 2016 Camaro wears a sharper, more angular design than the current model. This is especially the case when you look at the taut lines making up the rear. Chevy claims that the new shape underwent 350 hours of wind tunnel tests to be able to generate left lift, improve cooling and reduce wind noise in the cabin. A smooth underbody pan is among the aerodynamic tweaks, and it runs from underneath the front grille to the center of the Camaro. Chevy asserts that all of the changes at the front help reduce lift by 30 percent. Related VIdeo: 2016 Camaro is all about the Aero Total aerodynamic lift improved by 30 percent for improved stability 2015-05-11 DETROIT – After 350 hours of wind tunnel testing – often 24 hours a day – the new Camaro will slip more easily through the wind, and drivers of the Camaro SS will experience a marked improvement in reduced aerodynamic lift. These changes illustrate the lengths the aerodynamics team went to for improved performance, stability, cooling and lower wind noise intrusion "The importance of aerodynamics increases exponentially as we increase vehicle performance," said Kirk Bennion, Exterior Design manager. "As engine output increases, we need more engine cooling. As acceleration and top speeds climb, we need to reduce lift for better high-speed stability. However, we cannot make any changes at the expense of increasing drag, which can hurt fuel economy. "To balance these different aerodynamic targets, we tested literally hundreds of changes on the new Camaro, millimeters at a time." For example, the initial design called for the lower grille bars to be set at a 20-degree angle to the horizon. However, after meticulous testing, the team improved engine-cooling airflow by 1 percent by shifting the angle to 13 degrees – a change that achieved the airflow target while maintaining the original grille design. And rather than a traditional front air dam to reduce aerodynamic lift, the team developed a flush belly pan that stretches from the front grille to the center of the vehicle.

GM reports third straight sales drop in China in 2020

BEIJING — General Motors' vehicle sales in China fell 6.2% in 2020, as the U.S. automaker suffered a prolonged slowdown in the world's biggest auto market. GM, China's second biggest foreign automaker, delivered 2.9 million vehicles in the country last year, the company said on Wednesday, for a third straight decline in annual sales. But sales have been recovering in the second half of last year, up 12% between July and September and 14% in the final three months. GM has a Shanghai-based joint venture with SAIC Motor, in which the Buick, Chevrolet and Cadillac vehicle brands are made. It also has another Liuzhou-based venture, with SAIC and Guangxi Automobile Group, in which they make no-frills minivans and have started to make higher-end cars. Sales of its Buick brand grew 4% on the year and Wuling rose 9%, the statement said. Luxury brand Cadillac's sales increased 8%. Sales of GM's more affordable Baojun brand dropped 33% last year, while sales of its mass-market Chevrolet tumbled 30%. GM's delivery of 2.9 million vehicles in China follows 3.09 million vehicles in 2019, 3.65 million vehicles in 2018, and 4.04 million in 2017, for a three-year decrease of 28%.
