GM CEO Barra says 'we are selling every truck we can build'

DETROIT — General Motors Chief Executive Mary Barra said on Monday the automaker is "selling every truck we can build" and expanding North American truck-building capacity, even as U.S. gasoline prices hit record highs. Barra made her comments during the automaker's annual shareholder meeting. GM is pursuing a two-track strategy: Investing heavily in electric vehicles for North America, China and other markets, and funding those investments by trying to maximize profits from its North American combustion pickup truck and large SUV lineups. Barra said GM is planning higher-priced versions of its Silverado large pickup and its large SUV models. GM and its Detroit rivals Ford Motor Co and Stellantis NV rely heavily on sales of large pickup trucks and SUVs for global profits. High U.S. gasoline prices in the past have undermined consumer demand for relatively inefficient models. Nominal pump prices hit an average of above $5 a gallon for the first time ever last week, the federal government said Friday. GM is ramping up production of EVs. Barra said the Cadillac Lyriq electric sport utility is sold out through 2023. In response to shareholder questions, Barra said the "clear priority" for using cash generated by its operations is to "accelerate our EV plans." She did not rule out share buybacks or other approaches to returning cash to shareholders. GM still expects to increase production this year by 25-30%, despite continuing pressure on semiconductor supplies globally. Barra said GM is working to redesign vehicles to reduce the number of processors required by 95%. Barra serves as GM's board chair and CEO. GM shareholders overwhelmingly rejected a proposal to separate those roles.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.
