GM recalls 64k 2011-2013 Volts over carbon monoxide fears, stop sale on Trax and Encore

General Motors is recalling 50,249 Chevrolet Volts from the 2011-2013 model years in the US and an additional 13,937 exported examples because of fears over carbon monoxide buildup. According to a statement, if a Volt is accidentally left on while running on electric power, its internal combustion engine would eventually kick on to charge on the battery. If this happens in an enclosed space, then carbon monoxide can fill the area, leading to a potential exposure to the dangerous gas. According to GM, there have been two injuries reported due to this issue. To fix the problem, there's a software update to limit the time the vehicle can idle. According to Automotive News, GM is also issuing a stop sale on about 2,300 examples of the 2015 Chevrolet Trax and Buick Encore. In these compact crossovers, it's possible that the steering column assembly could touch the power steering circuit board and cause damage over time. This could potentially cause the system to stop working. Automotive News indicates that the automaker is still working with the supplier to get the necessary parts to repair this problem. General Motors is recalling 50,249 Chevrolet Volts in the U.S. from the 2011-2013 model years to implement a software update that will limit the amount of time a vehicle can be left idling in the "on" or "run" position. If a driver exits the vehicle and inadvertently leaves the vehicle "on" by failing to react to cues and warning chimes emitted by the vehicle, the vehicle's high-voltage battery will drain after a period of time and the gasoline engine will begin to run. If the gas engine runs for a long period of time within an enclosed space, such as a garage, carbon monoxide could build up. GM is aware of two injuries, both related to carbon monoxide build up. The total recall population including Canada and exports is 64,186. Related Video:

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.

Chevrolet Chaparral 2X Vision Gran Turismo could only work in a video game [w/video]

There's something wondrous about the Vision Gran Turismo series of concepts that has let companies go wild with completely imaginary concepts for Gran Turismo. For Chevrolet's crack at the idea, it has taken a page out of its performance past with the Chaparral Can-Am racers of the '60s and '70s, with its designers having reinterpreted that period look for the future of motorsports as the Chaparral 2X. In real life, the 2X looks even better than in earlier photos. The design takes inspiration from someone in a flying suit with head down and arms outstretched, an influence you can really see that in the vehicle's shape. The driver lies facedown inside with the instruments projected onto a visor. Unfortunately, the powertrain here is a complete flight of fancy and works purely in the video game world. It imagines a laser propelled by lithium-ion batteries and an air-powered generation to make 900 horsepower. The 2X has a theoretical top speed of 240 miles per hour and hits 60 mph in a lightning-quick 1.5 seconds. Scroll down to see the concept on video with Chevrolet designers describing their inspiration and read the company's full announcement. It's also downloadable in Gran Turismo 6. Chevrolet to Show Chaparral Vision Gran Turismo Concept Boundary-pushing, Chevy-powered race cars changed motorsports design DETROIT – When racers Jim Hall and Hap Sharp founded Chaparral Cars in 1962, few could have guessed how they would shake up the conformities of the racing world – and fundamentally change it. Through pioneering applications of aerodynamics and aerospace technology, and a partnership with Chevrolet Research and Development, Chaparral Cars advanced the science of racing cars. It also triumphed on the track over well-established sports car companies from around the world, using Chevrolet horsepower. It was that spirit of innovation that inspired the Chevrolet Chaparral 2X VGT concept race car developed for the Vision Gran Turismo project, which celebrates the 15th anniversary of PlayStation® racing game Gran Turismo by inviting manufacturers to give fans a glimpse into the future of automotive design. It will debut at the Los Angeles Auto Show, Nov. 19, and gamers will be able race the Chaparral 2X VGT following the release of an online update for Gran Turismo 6 during the holiday season.
