J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Recharge Wrap-up: Q50 Hybrid video, Iran's biodiesel weed

A new video from Infiniti showcases the Q50 Hybrid's kinetic energy recovery technology, borrowed from Formula One. The video details what is going on inside both the Q50 Hybrid and the racecar when it gathers energy to store for later use, offering better performance than an internal combustion engine alone. In the Q50 Hybrid, that electric energy helps the car accelerate from 0-60 in 4.9 seconds. The video also serves to highlight the relationship between racing innovation and performance and efficiency improvements in production vehicles. See the video above. The 2015 Toyota Prius C has been named a Top Safety Pick by the Insurance Institute for Highway Safety (IIHS). The compact hybrid, updated for the 2015 model year, has been upgraded from a "poor" to "acceptable" rating in the small overlap crash test, placing it on the Top Safety Pick list. Beginning in the 2016 model year, cars will have to score a "good" rating on the test to make the list, which means further improvements will be necessary if Toyota wants the Prius C to maintain its safety status with the IIHS.

John and Lisa Brichetto's Northington Energy LLC received a state loan to produce biodiesel in 2011, but the facility never started production and was later foreclosed upon. In addition to the $142,215 the Brichettos defrauded from Tennessee, the state also invested in utilities and roads, while the US Department of Agriculture also paid for site improvements.

Scientists at the Islamic Azad University have created two liters of biomass for biofuel from flixweed. Flixweed, also called herb-Sophia and tansy mustard, is a non-edible weed that grows in various climates with little to no effort. It was found to contain 22 percent oil and fatty acids, and the biomass contains oxygenated chemical components. "This issue is important because the atomic oxygen in the fuel of a car directly cuts exhaust and the dangerous carbon monoxide and cancerous particles suspended in air," says Mehdi Alami, a chemistry graduate working on the project.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.
