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:

Infiniti Formula One-inspired Q60 Project Black S has been canned

Infiniti gave enthusiasts a preview of what a high-performance hybrid coupe equipped with Formula One-derived technology could look like when it released the Q60-based Black S concept in 2017. While executives hinted the 563-horsepower model could reach production sooner rather than later, the company confirmed it's been axed. Industry trade journal Automotive News learned the concept was consigned to the automotive attic from an Infiniti spokesman. He pointed out the design study "continues to inspire us," but he didn't explain why the Black S won't reach production. We're not surprised by the decision, though. It was a complex, eye-wateringly expensive version of a slow-selling model unveiled in 2015. Making the numbers add up was likely easier said than done.  Interestingly, many Infiniti dealers didn't want the Black S. "In today's market, a premium Japanese performance coupe has to be very low volume. Anything that Infiniti produces for its dealers, we want it to be a volume product. We're not really in the racing business. I would much rather see something like the QX60. That's a volume vehicle, that's where this company needs to go," opined Ed Lennon, the chairman of the Infiniti National Dealer Advisory Board, in an interview with Automotive News. Unveiled at the 2017 edition of the Geneva auto show, and presented again the following year in Paris, the Black S was powered by a gasoline-electric hybrid drivetrain built around the twin-turbocharged, 3.0-liter V6 that powers the Q60 Red Sport 400. It worked with three motor-generator units similar to the ones found in the Kinetic Energy Recovery System (KERS) fitted to Formula One cars. One spun the rear wheels, and the others were connected to the turbochargers to eliminate lag and deliver instant boost. Infiniti quoted a sub-four-second sprint to 60 mph. Hybrid technology adds weight, and Formula One-like components are no exception. Infiniti noted the drivetrain weighed 441 pounds more than the Red Sport 400's V6. Had it been built, the Black S would have relied extensively on carbon fiber to keep weight in check, and it would have offered a 50/50 weight distribution. Much has changed since 2017, however. Roland Krueger, the former Infiniti CEO who championed the project, left the company in January 2019 to lead Dyson's ill-fated automotive unit. Infiniti announced plans to exit the European market later that year, and it ended its participation in Formula One in 2020.

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.
