Porsche tops J.D. Power quality index as Korean brands soar

While complaints about infotainment systems remain a thorn in the side of automakers for J.D. Power's annual Initial Quality Study, there's a lot to celebrate this year. The average number of problems reported per 100 vehicles fell to 112 in 2015 – a three-percent improvement compared to 116 in 2014. The results of this year's survey are based on the responses of over 84,000 people about problems within the first 90 days of buying or leasing a 2015 model-year vehicle. For the third consecutive year, Porsche tops the rankings with an average of 80 problems per 100 vehicles. Although, that's slightly more than the 74 the German sportscar maker scored in 2014. "While the Japanese automakers continue to make improvements, we're seeing other brands, most notably Korean makes, really accelerating the rate of improvement," Renee Stephens, vice president of US automotive quality at J.D. Power, said in the study's release. In fact, Kia ranks as one of the biggest movers in this year's list. The Korean brand jumped to second place from seventh last year. The company had an average of 86 problems per 100 vehicles, a 20-point improvement. Third place went to Jaguar with an average of 93 problems reported, versus last year's second-place finish with 87 of them. Fourth place was Hyundai, and fifth-place Infiniti also earned a gold star for improvement with 97 issues per 100 vehicles – 31-points better than last year. Fiat still anchored the bottom of the list. However, its 161 problems this year is a lot better than the 206 in 2014. Ranked by nationality, Korean brands (Hyundai and Kia) are now leading the industry in initial quality with an average of 90 problems reported per 100 vehicles. According to J.D. Power, this is the first time Europe's figure beat Japan with 113 and 114 issues, respectively. The American brands also averaged 114. Whereas General Motors dominated last year, the segment awards are spread out in 2015. GM, Hyundai, Nissan, and Volkswagen Group are all tied with four models each earning prizes.

Tesla leads and Infiniti bleeds in Consumer Reports' satisfaction survey

According to Consumer Reports, Tesla owners are more likely to rave about their vehicles than any other brand. And we're not surprised — Tesla has performed very well in past customer satisfaction surveys, despite the fact that the electric cars themselves tend to have more problems than most other automobiles. Second place went to Lincoln, which interestingly had a higher cumulative score than Tesla in individual category measurements like comfort and storage space. Ram, a truck-only brand, rounded out the top three. The consumer-focused magazine bases its owner satisfaction score on responses to a very simple question: Would you buy this exact car again? The higher percentage of owners who answer "definitely yes" to that question, the higher the satisfaction score. Further breakdowns are scored for other parts of the ownership experience, which is why brands that rank poorly in Consumer Reports' own reliability charts — like Tesla and Lincoln, for example — can still earn top marks for satisfaction. The lowest-ranked brands for satisfaction are Cadillac, Nissan and Infiniti. Interestingly, Cadillac performed better than average in Driving and Comfort and middle-of-the-road in the In-Car Electronics and Cabin Storage, but like most other brands, scored poorly in Value. In fact, only Subaru, Mazda and Volkswagen scored better than average in Value. Nissan and especially Infiniti earned comparatively low marks across the board to go along with the bottom-of-the-barrel satisfaction score. Here's the full list of automakers from Consumer Reports' satisfaction survey, ranked in order from best to worst: Tesla Lincoln Ram Chrysler Subaru Hyundai Porsche Dodge Mazda Toyota Kia Mini BMW Ford Audi Honda Volvo Volkswagen Lexus Jeep GMC Chevrolet Mercedes-Benz Buick Cadillac Nissan Infiniti It's worth diving into the individual category scores in addition to the official finishing order for a full look at the results. For instance, despite the fact that automakers like Lincoln and Ford use similar infotainment systems, their In-Car Electronics scores don't quite match up. Also, some automakers have full lineups with multiple cars, trucks and SUVs while others offer just a couple of nameplates. Head on over to Consumer Reports for all the details.

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.
