Auto sales in March and first quarter down nearly across the board

Nearly every major automaker reported weak U.S. sales for March and the first quarter of 2019, citing a rough start to the year, but said a robust economy and strong labor market should encourage consumers to buy more vehicles as 2019 rolls on. GM, which no longer releases monthly sales figures, saw first-quarter sales fall 7 percent, with declines across all brands. Sales of Silverado pickup trucks fell nearly 16 percent and the high-margin Chevy Suburban large SUV dropped 25 percent. Ford also no longer releases monthly sales numbers, but is due to release its first-quarter sales figures on Thursday. According to industry data, Ford's sales fell 2 percent in the quarter and 5 percent in March. Ford representatives did not immediately respond to requests for comment. FCA reported a 7 percent fall in U.S. sales in March and a 3 percent drop for the first quarter. All of FCA's brands dropped in March, except for Ram, which saw a 15 percent increase in pickup truck sales. "The industry had a tough first quarter, but with spring finally starting to show its face and continued strong economic indicators ... we are confident that new vehicle sales demand will strengthen going forward," FCA's U.S. head of sales, Reid Bigland, said in a statement. Toyota reported a 3.5 percent fall in U.S. sales in March and 5 percent for the first quarter, hurt by declining demand for its Corolla sedans and Camry vehicles. "While some of our competitors are abandoning sedans, we remain optimistic about the future of the segment," Toyota said in a statement. Nissan posted a 5.3 percent drop in sales in March, and its first-quarter sales were down 11.6 percent. Honda and Hyundai bucked the trend. Honda's U.S. sales rose 4.3 percent in March and 2 percent in the quarter, while Hyundai's were up 1.7 percent and 2.1 percent, respectively. Passenger-car sales suffered throughout the January-March quarter compared with the same period in 2018 as Americans continued to abandon them in favor of larger, more comfortable pickup trucks and SUVs, which are far more profitable for automakers. The battle for market share in the particularly lucrative large-pickup truck market intensified in the quarter, as Fiat Chrysler Automobiles' Ram brand outsold the U.S.' No. 1 automaker General Motors' Chevrolet-brand trucks. The two automakers have both launched redesigned pickup trucks.

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.

Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.
