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.

GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

Junkyard Gem: 1980 Chevrolet LUV Mikado

During the 1970s and into the 1980s, each member of the Detroit Big Three imported Japanese small pickups and sold them with Ford (Mazda Proceed), Dodge/Plymouth (Mitsubishi Forte), or Chevrolet (Isuzu Faster) badges here. Ford developed the Ranger and killed the Courier for 1983 (though Americans could still buy the Mazda-badged version all the way through 1993), while The General axed the LUV after the S-10 debuted in the 1982 model year. Isuzu sold the same truck as the P'up through 1987, though, and we might as well follow up our recent P'up Junkyard Gem with its LUV predecessor. LUV stood for Light Utility Vehicle, and I've managed to spot a handful in the boneyards over the years. This one now resides in a yard in northeastern Colorado. The Mikado trim package included striped seat upholstery and a sporty steering wheel, plus these cool dash badges. As far as I can tell, no LUV Mikado advertising featured any Gilbert and Sullivan tunes. This one is fairly rusty for Front Range Colorado, and it has endured a bed swap from some other small truck. The engine is the 75-horse Isuzu 1.8-liter. Members of this engine family went into everything from Chevy Chevettes to Isuzu Troopers in the United States. Very unusually for a small pickup during the Malaise Era, this one has a luxurious automatic transmission. Acceleration must have been a leisurely affair in this truck. Air conditioning? Unheard of! Someone stuck every one of their lunchtime apple stickers on the driver's door. After 41 years of work, this truck is done. Come on strong in a LUV of your own!
