Infiniti QX50 concept previews production model with variable compression engine

Infiniti revealed its QX50 concept ahead of its official debut at the Detroit Auto Show, and despite the concept title, it looks pretty much production-ready. The company calls the crossover "an evolution of the QX Sport Inspiration" concept, and that's certainly accurate. Side-by-side, the QX Sport, which we already figured was previewing a new QX50, and this concept look nearly identical. The primary changes are bumpers and side skirts that feature the obligatory aluminum trim to look like skid plates, and simple black plastic fender flares. The overall result is a crossover that is pleasant but not exactly exciting that bridges the gap between the small and swoopy QX30 and the large QX60. The plain wrapper hides plenty of impressive technology, though. Under the hood is Infiniti's fascinating variable-compression turbocharged engine. It's a 2.0-liter inline-four that can alter its compression ratio to anything between 8:1 and 14:1. The result is an engine that produces an estimated 268 horsepower and 288 lb-ft of torque. Infiniti says the four-cylinder should be about 27-percent more efficient than a comparable V6. In addition, while the company says this concept just shows a potential application of the engine, it's safe to say that you can expect it in the production model. With the new engine, the QX50 will also switch from to a front-drive platform, with all-wheel drive definitely an option or possibly standard; the current QX50 is based on the aging rear-drive FM platform used on other Infinitis and the Nissan 370Z. The other new tech buried in the QX50 concept's body is what Infiniti calls the "first production-ready incarnation" of its ProPilot semi-autonomous technology. The company doesn't go into great detail about what it will do except for handling stop-and-go highway traffic. We would hazard a guess that the system is functionally the same as the one introduced on the Nissan Serena minivan in Japan. It goes by the same name and can handle stop-and-go traffic, as well as maintain the car's lane position and distance behind other cars. It's another safe bet that we'll see this system in the production model. Other details about the car, such as the interior, have yet to be revealed. We're sure to see it as well as other information about the QX50's technology when it makes its full debut in Detroit. Related Video:

2019 Infiniti QX60 Drivers' Notes Review | Past its prime

The 2019 Infiniti QX60 is a three-row crossover from Nissan's luxury brand. It's based on the Nissan Pathfinder, sharing the same basic platform and powertrain. It sits near the top of Infiniti's lineup, above the new QX50 and just below the body-on-frame QX80. That said, the car-based platform underneath the QX60 means its actually more spacious than its truck-based sibling. Power comes solely from a 3.5-liter V6 making 295 horsepower and 270 pound-feet of torque. All-wheel drive is available, though our tester was a front-wheel drive model. The 2019 QX60 starts $46,795, but our tester has nearly $20,000 worth of options. The $5,000 limited package adds upgraded leather on the seats and steering wheel, dark wood trim, 20-inch wheels and chrome trim on the exterior. The $3,400 proactive package adds safety features like lane-departure warnings, blind-spot monitoring, backup collision intervention and adaptive cruise control. Other options include back-seat entertainment ($2,150), a wifi hotspot ($495) and the $3,500 sensory package (a Bose audio system, ventilated front seats, heated second-row seats, a motion-activated liftgate and a moonroof for the second and third rows). Editor-in-Chief Greg Migliore: I'm immediately struck by the interior. It's quiet and comfortable. The quilted leather on the door panels is almost decadent. Infiniti is really going for it with this kind of interior styling. Some might say it's a little bit much, but generally, I think the company gets it right. Same with the outside. Infiniti tries to make a statement, and this swoopy, creased design is reason enough to buy the QX60. Our tester has the 295-hp V6, which is plenty capable. There's a lot of torque steer with the front-wheel-drive setup. It's kind of fun, but not really the dynamic most buyers are going for it. Overall, I like the QX60. It's big, comfortable, luxurious and powerful. Get AWD, though, as FWD in the snow is a little squirrely in something this large. Road Test Editor Reese Counts: Unlike Greg and Joel, I wasn't bowled over by the interior. I couldn't find a comfortable seating position for the life of me. The bottom cushion wasn't deep enough and the back seemed to protrude out at odd points into my spine. The leather looks and feels OK, but that was my only highlight. The overall interior design looks fat and boring, especially compared to models from Mercedes-Benz and Lexus. Just look at some of the details like the vents and steering wheel.

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.
