This is how GM is hiding new Chevy Volt in public

General Motors is letting the public know that, well, it's not about to let the public know anything else about the next-generation Chevrolet Volt. But the automaker is willing to talk about its camouflaging process for upcoming versions of the extended-range plug-in. So it's a half-hearted secret, at best. GM actually has a "camouflage engineer" charged with creating ways to disguise the styling of new vehicles. In the Volt's case, the company is applying black and white swirly color patterns on top of the materials, such as plastics, vinyl and foam, that are used liberally across the body. It's all part of a teaser campaign that started last month with pictures of part the 2016 Volt. Earlier this month, GM said it was keeping track of Volt drivers' habits as it works on the next-gen model. The company noted that more than four out of five trips are being made in all-electric driving mode, and that 60 percent of Volt owners use a plain-old 100-volt outlet to recharge their cars. The car is slated to make its global debut at Detroit's North American International Auto Show next January, and the early word is that performance and all-electric range will be improved (we should hope so). The car will also be sleeker. By how much, we can't tell yet, because of those darn swirly patterns. GM's got more non-details in its press release below. Engineers charged with hiding styling while vehicle testing proceeds in public DETROIT – The styling of the next-generation Chevrolet Volt is one of the automotive world's best-kept secrets. Keeping customers and media eager to see the successor to the groundbreaking original at bay until the new Volt debuts at the North American International Auto Show in Detroit in January is tricky business. First, it is engineers, not designers, who are charged with creating camouflage that balances styling secrecy with the need to validate the Volt and its systems in public. "If it were up to me it would be a shoebox driving down the road," said Lionel Perkins, GM camouflage engineer. "The design team wants us to cover more of the vehicle and the engineering team needs to have enough of the vehicle's weight and aero exposed so that the tests in the development process are consistent with the product that will come to market." The engineers responsible for the "cool" designs covering the car might deserve style points but their efforts are intended strictly to hide the metal beneath.

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.

Chevy gives Camaro Red, Black Accents for SEMA

Just the other day, Chevy announced a series of modified show cars it's planning to bring to SEMA this year. Now it has revealed full details on what could prove the most enticing among them in the form of a pair of Camaros. These new Red Accent and Black Accent editions are based on the new, sixth-generation 2016 Camaro SS. The former starts out as a Camaro SS convertible, done up in silver with red trim inside and out. It's got a leather interior, custom grille, hash-mark fender graphics, blacked-out bowtie badge, and 20-inch alloys. Even the engine is visually enhanced with a red cover. While it was at it, Chevy also dropped the suspension and fitted a new air intake and Brembo front brakes. Joining it is the Black Accent concept, based on a red Camaro SS coupe. As its name suggests, it's got a blacked-out aero kit, bowtie badge, and fuel cover, along with darkened tailllamps and satin black stripes. It also gets a black leather interior and its own set of 20-inch wheels, along with the aforementioned lowering kit, Brembo front brakes, air intake, and red engine cover. The Accent concepts are designed to showcase the extent of the accessories Chevy is offering for the new Camaro, and will be showcased at SEMA alongside modified versions of the Spark, Trax, Malibu, Colorado, and Sierra. Feel free to scope out the gallery above and the details in the press release below.
