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.

New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver. You can view how it works in motion via the video below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

2020 Infiniti Edition 30 models priced

The 2020 model year marks the 30th anniversary of Infiniti, and as announced back in August, the brand is rolling out specially tweaked Edition 30 models across the bulk of its lineup. We now have more details and pricing for the commemorative editions, which are available on the Q50 sedan, Q60 coupe, QX50 compact crossover, QX60 mid-size crossover, and QX80 full-size SUV. The Q50 Edition 30 sedan's starting price is $43,700 with rear-wheel drive and $45,700 is all-wheel drive. The Q50 Edition 30 is priced between the Luxe and Sport trim levels, but its equipment is closer to that of the Sport. Although it's $4,800 cheaper than the Sport, the Edition 30 adds full-speed adaptive cruise control, but it uses the smaller brake rotors of the Luxe trim and it skips the Sport's adaptive damping. Unique Edition 30 elements include dark-chrome 19-inch wheels and exterior trim, black mirror caps, and a black mesh grille. The Q60 Edition 30 coupe is offered as a $4,200 package for the Luxe trim level. Added to the $45,500 base price of the rear-wheel-drive Luxe coupe, and you get a starting price of $49,700 for the Edition 30. All-wheel drive is another $2,000. Exterior enhancements mirror those of the Q50 Edition 30. The Q60 Edition 30 package also adds navigation, an around-view monitor, power-adjustable steering column, memory settings, rear auto-braking, adaptive cruise control, heated seats and steering wheel, and a few lesser items. The QX50 Edition 30 compact crossover builds on the mid-level Essential trim level. It's sold as a package for $1,200 and includes adaptive cruise control, blind-spot intervention, lane-depature prevention, and adaptive front lighting, plus 20-inch dark-finish wheels, dark-chrome exterior accents, a body-color rear diffuser, and a black headliner. For the range-topping QX80, the Edition 30 is a package that adds $3,500 to the Luxe (base) trim level. Besides the dark-chrome exterior trim and dark-finish 22-inch wheels, it includes a rear camera mirror, lane-departure prevention, adaptive cruise control, blind-spot intervention, and a black headliner. On Infiniti's most popular vehicle, the QX60, full details of the Edition 30 are not yet available, but we're told the model will start at $50,850. That represents a $4,700 premium over the Luxe trim level, and includes the content of the ProAssist package as well as the Edition 30 design enhancements.
