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.

German police Corvette promotes safe aftermarket tuning

The German organization Tune It! Safe! promotes safe, legal vehicle tuning in the country, and it probably doesn't have to worry about anyone breaking the law when this Polizei-themed Chevrolet Corvette is on the scene. The Vette is on display at the Essen Motor Show and is the group's latest police-wrapped tuner car, following models like the Brabus Rocket, Mercedes-Benz CLS, and AC Schnitzer-tuned BMW 123d in years past. Tikt Performance did the tuning this time, and the German company added a full carbon-fiber body kit for the Vette, including a front lip, side sills, rear spoiler, and relatively understated wheel flares. It also installed forged wheels that measure 19-inches in front and 20-inches in back and wrapped them with Hankook Ventus S1 Evo tires. To really let the coupe look the part of a proper Polizei car, the tuners included police lights from Hella and the appropriate blue-and-white wrap. Tikt left the 6.2-liter V8 alone to produce 460 horsepower and 465 pound-feet, and the power routes through a seven-speed manual. Even with the stock performance, this police-themed 'Vette would still look fantastic blasting down the Autobahn with the lights flashing. World premiere at the Essen Motor Show: initiative for safe tuning starts the new campaign year with TIKT Performance Corvette A powerful look for a powerful campaign: TUNE IT! SAFE! presents innovative design and maximum precision Innovative design, maximum precision and unique performance – with an enhanced Corvette, TUNE IT! SAFE! shows that attractive, creative tuning in no way has to conflict with legal requirements. In the new campaign year, the seventh generation of a sports car icon stands as a symbol and shining example of safe automobile tuning and 100 per cent driving fun. The campaign car of the initiative for safe tuning, sponsored by the Federal Ministry of Transport, the Association of Automobile Tuners (VDAT) as well as numerous other organisations and institutions, sees its premiere at the Essen Motor Show (Hall 10, Stand F104). TUNE IT! SAFE! also continues its partnership with premium tyre manufacturer Hankook. Tuning specialist TIKT Performance based in Upper Bavaria is responsible for the innovative conversion of the new TUNE IT! SAFE! police car.

2016 Chevy Volt will be available across Canada, unlike most of US [UPDATE]

UPDATE: The story's been updated to add a response from General Motors of Canada. It's not enough that the Toronto Blue Jays may be the most intimidating team in Major League Baseball. Now, it appears that our neighbors to the north will also have some bragging rights in regards to General Motors' Chevrolet Volt extended-range plug-in vehicle. Specifically, most of Canada will have access to the 2016 version before most of the US will. In fact, the car will be available in Canada before people can buy it in Michigan. A trip to Windsor, Ontario, anyone? The Volt, which will boast a longer plug-in range than the current version, could go on sale in Canada as soon as November, GM Authority says. The model's second-generation version may debut in California as soon as this month, and is slated to be sold later this year in the 10 other states that abide by the so-called CARB (California Air Resources Board) rules for zero-missions vehicles. Those states include Oregon, Maine, New York and Massachusetts. But not GM's home state of Michigan. Either way, the new generation model's debut can't come soon enough for the US automaker, as Volt sales in 2015 have seriously lagged the 2014 numbers because of people waiting for the new version. "We will receive the 2016 Volt in Canada this fall, starting with our key Volt markets in Quebec, Ontario and British Columbia," wrote General Motors of Canada spokesman George George Saratlic in an e-mail to AutoblogGreen. "Note these are also the three provinces that provide provincial incentives on EV purchases. We'll then roll out Volt to the rest of the country." Last week, details were revealed about the first sales of the 2016 Volt, where marketing efforts will be concentrated among the largest plug-in buying states in the union. The other 39 states will get their shot starting next year with the 2017 model-year variant. Related Video:
