2016 Chevy Volt powertrain video teasers

If there's one thing we've learned about plug-in vehicle fans, you have a thing for seeing your cars get made. The series of videos showing BMW i3 production was strangely popular, as were the shots from inside the VW e-Golf plant. Well, with General Motors pulling the veil off of the 2016 Chevy Volt this week, it's time to take a peek at the production process for that vehicle as well. You're welcome. Up first we've got a clip from CNN Money showing a little bit about how the new Volt's new battery pack and other powertrain components are made. Those of you who are trying to read the lithium tea leaves and see if the new shape reveals that the 2016 Volt will have five seats might want to check it out. Then we've got two clips from GM itself, one showing an animation about the updated Voltec powertrain and another with some B Roll of the old Volt. Since GM doesn't want us to see the new car quite yet, we'll have to enjoy this for now. Watch below. This content is hosted by a third party. To view it, please update your privacy preferences.

2019 Chicago Auto Show photo gallery: All of the grilles

Do you like trucks? How about grilles? Like really big, shiny, chromey, in-your-face, could-be-made-by-Broil-King grilles? Well, the Chicago Auto Show is the place to be. Traditionally known as the truck show of the annual auto show circuit (at least those covered by national media), Chicago has what seems like a small national park's worth of acreage devoted to both consumer and commercial trucks. From humble extended cab Ford Rangers to a mammoth F-650 with cherry picker sprouting from its aft quarters, there's bound to be a truck for everything. And they all have grilles. So above is our gallery devoted to them, because hell, why not? Should you want to know about the trucks attached to those grilles, check out our coverage below.

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.
