GM natural gas-powered vans recalled due to possible leak

General Motors is recalling almost 3,200 of its compressed-natural-gas powered utility vans because of possible leaks. GM and the National Highway Traffic Safety Administration (NHTSA) released a notice last week saying that 3,196 Chevrolet Express and GMC Savana CNG vans are on recall, though no accidents have been reported due to the possible issue. The recall is specifically for vans for model years ranging from 2011 to 2014. The recall stems from a potential leak from the compressed natural gas high-pressure regulator, and such a leak could cause a fire or explosion. GM will replace the vehicles' high-pressure regulator in order to fix the problem, will do it free of charge and is instructing owners to contact Chevrolet or GMC customer service to arrange for the parts replacement. Utility vehicle makers like General Motors have pushed for fleet sales of CNG-powered vans and trucks for the past few years and have touted them for their cheaper refueling costs relative to standard gasoline, not to mention the fact that natural gas can be readily sourced from throughout North America (thanks, fracking). According to CNGPrices.com, compressed natural gas sells for about $2.22 a gallon, on average, while the AAA is pegging the average price of gas at $3.34 a gallon. NHTSA has posted information on the recall here. Featured Gallery News Source: NHTSA via Reuters Green Chevrolet GM GMC Natural Gas Vehicles CNG gmc savana

GM says its electric pickup truck is 'in development'

GM President Mark Reuss just reiterated the company's support for an electric pickup project. He also claimed that GM is going to be selling its future electric cars at "very average transaction prices" during the same conference with Wall Street analysts. Previously, Mary Barra informed the world of GM's electric pickup truck aspirations, but didn't tell us anything else. Reuss says the truck is already in development, though, according to a Wards Auto report. "We will have a complete electric lineup, including a pickup truck that's in development," Reuss said. This comment marks the second time GM has gone on the record about its intentions to bring an electric pickup to market. Additionally, Reuss said GM's third-generation global EV platform will be used to help develop the electric pickup. This platform was recently announced to underpin at least 20 new EVs from GM in the future — the platform itself is slated to be unveiled in 2021. Of course, this platform will be flexible and modular to allow various body styles to be used with it, a truck being one of those. Reuss still hasn't said what GM brand the pickup will be sold under, or what class of truck it will be. GM thinks this new platform is also going to be what helps it drive down the cost of building EVs. "We'll reach parity a lot sooner than people think," Reuss said comparing EVs to traditional gas-powered engines. "We're driving down the cost of batteries and the whole EV in general." As for electric pickups, Ford is also deep in development of its own electric F-150. However, neither of these truck projects have official timelines on them, so we can't say when they'll hit the market. For now, the cross-town rivals are both in development with their respective electric pickups. Even further across town is Rivian (in which Ford just invested half a billion dollars), a company that says its electric R1T pickup is right around the corner, with the official due date being end of 2020 for the time being.

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.
