How Chevy used popular Instagram user to promote 2016 Volt

A picture is worth a thousand words. When it comes to Chevrolet and its Volt extended-range plug-in, the automaker is hoping pictures can be turned into a few more buyers. The company extended a little love to one popular social-media practitioner to see if the trick works. Former biochemical engineer Kevin Lu started his Instagram account a couple of years ago during a road trip, and the quality of his shots has attracted about 181,000 followers. With that popularity in mind, Chevy brought Lu up to Detroit to check out the unveiling of the next-generation Volt at the Detroit Auto Show last month. Lu also got to see the Detroit-Hamtramck Assembly factory where the Volt is built, Automotive News reports. As for the next-gen Volt, Chevy says a more efficient powertrain and lighter battery help give the car an all-electric range of up to 50 miles and a total driving distance of more than 400 miles. Chevy also touts the model's streamlined grille and (tight) seating for three in the rear. General Motors hopes a combination of those improvements and exposure from sources such as Lu and his Instagram account (and some sleepy ads, apparently) revitalize sales of the model. Last year, Volt sales fell 19 percent to 18,805 units.

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.
