No diesels in the running for 2016 Green Car Of The Year

It's a new era for the Green Car Of The Year. In the past, the theme of the award was to take a broad look at alternative powertrains and pick the best among them. "Clean diesels" from the Volkswagen group were often among the finalists and won the award twice. For the 2016 edition - which will be handed out at the LA Auto Show next month - not a single diesel made the list. There's little wonder why. Green Car Journal, which names the winner with a panel of experts, had to strip two VW brand vehicles of their past wins. The 2009 VW Jetta TDI, which won in 2008, and the 2010 Audi A3 TDI, which won in 2010, have both lost their titles now that the world knows about the "defeat devices" that VW installed in many of its TDI vehicles around the world. So, what does that leave us with for 2016? Two plug ins, a hybrid, and two gas vehicles. The two electric vehicle are the Audi A3 e-tron and the Chevy Volt, while the all-new Toyota Prius (which will come with a plug-in version later) is the lone pure hybrid. Rounding out the pack are two efficient gas models: the Hyundai Sonata and the Honda Civic. This is the tenth year for the Green Car Of The Year, and it will be interesting to see if diesels can come back into the award's good graces (for the record, no diesels were among the finalists in 2013, either) in the future. For now, we'd like to know who you think should win. You can read more about the finalists in the press release below and then cast your vote in our poll.

The 2016 models include the Audi A3 e-tron, Chevrolet Volt, Honda Civic, Hyundai Sonata, and Toyota Prius. An increasing number of vehicle models are considered for the Green Car of the Year® program each year, a reflection of the auto industry's expanding efforts in offering new vehicles with higher efficiency and improved environmental impact. Green Car Journal has been honoring the most important "green" vehicles every year at the LA Auto Show, since its inaugural award announced at the show in 2005.

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

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.
