Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

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.

Toyota lowering Prius sticker prices in California

For the citizens of the state that has the biggest impact on Prius sales, it's understandable that Toyota might be offering its biggest perks there. With the next-generation version of the world's most popular hybrid not likely to see the light of day until the 2016 model year, the Japanese automaker is looking to spur sales as a stopgap measure. And that's especially true for the Prius C compact and the Prius Plug-in Hybrid. Toyota has bumped incentives for potential Southern California buyers of the Prius C to about $2,000 off the MSRP, which is up from $750 and about the same size of the perk given to prospective Prius Plug-in buyers, according to numbers from CarsDirect. For the standard Prius Liftback and the Prius V wagon, Toyota increased its discounts by about $500. The perks went into effect April 1 and will last until May 4. Toyota spokeswoman Amanda Rice confirmed to AutoblogGreen that the $2,000 incentive for the Prius C is specifically for the 2014 model year, and that the 2015 model year spurs a $750 incentive. She also confirmed that Toyota this month increased standard Prius lift back cash-back offer to $1,750 from $1,250, though amount offered can change by region. "While we will do what is necessary to remain competitive, Toyota's practice is to always lead with the product, not the deal," Rice wrote in an e-mail to AutoblogGreen. "The use of our incentives is tactical, reinforcing our value and focus on keeping our products competitive in the market." The Prius family was California's most popular passenger vehicle in 2012 and 2013, but sales since then have fallen off. Through the first quarter, US Prius sales were down 14 percent from a year earlier after falling 11 percent last year to about 207,000 units. A Toyota representative didn't immediately respond to a request for comment from AutoblogGreen on the increased incentives in the face of reduced sales. Related Videos:
